At a glance
Daniel Miessler sits down with Dan DeCloss, founder of PlexTrac, for twenty five minutes that start as a founder interview and turn, about seven minutes in, into a live walkthrough of the actual product. DeCloss has been in cyber security for twenty plus years, came up through GRC before moving to penetration testing, and built PlexTrac out of a specific personal grievance: he loved testing and hated writing the report. Miessler, a pen tester himself, says the same thing in almost the same words at 1:50.
But the conversation is not really about reporting anymore. The thesis DeCloss returns to over and over is that the industry no longer has a discovery problem. Scanners find plenty. Pen testers find plenty. AI is about to find vastly more. What nobody can answer is which of the twenty three thousand open finding instances in front of you is the one that will actually get you breached, and that gap is what PlexTrac has spent the last several years growing into: aggregate every finding source into one place, score it against the business context that is true for your company, hand the security team a ranked list, and then push the work out into Jira, ServiceNow, or Azure DevOps so the people who actually fix things never have to log into a security dashboard.
The demo section is the meat. DeCloss clicks through exposure management, the risk scoring algorithm editor, integrations, status history, the workflow automation engine, the write ups and narratives libraries, MITRE ATT&CK based playbooks that generate a finished report at the end of an engagement, compliance questionnaires, and asset management. Then the last three minutes turn to what happens when Claude Mythos class models start finding vulnerabilities at machine speed, and DeCloss lands on a position that is both modest and useful: the answer is not to slow AI down, it is to put AI upstream in the SDLC so less broken code ships, and downstream on the backlog so defenders fix the right things first. This page rebuilds the whole conversation in order, including the parts of the demo that only make sense if you saw the screen.

The problem he is actually hot on
Miessler opens with the question he says he always likes to start with: what is the problem you are really hot on and excited to try to solve?
DeCloss answers with his own career shape. His background is penetration testing. He has been in cyber security for twenty plus years. And the thing he has always tried to focus on is helping organizations prioritize the right things, meaning the things that will actually get them breached, then remediate those things, then stay focused on what an attacker can genuinely do inside their environment.
The origin of that focus is a frustration. He grew up partly in the GRC space, and with a technical background sitting underneath him, he kept feeling that GRC was not really asking the operative question. Not "did we check the box," but "what are attackers actually doing in environments, and how are those things actually getting people breached?" That gap is what pulled him toward penetration testing, where the technical aspects are literally how an attacker does the work. He describes himself as a hacker by trade in the older, nicer sense of the word: someone who always wants to understand how things work. Those were the things that got him excited.
Why PlexTrac exists: he hated writing reports
Then he started PlexTrac, and the founding motivation is refreshingly small and specific. He wanted to remove some of the friction in the pen testing process. They started in the pen test reporting space because, in his words, he hated writing reports and hated the lack of collaboration on findings, which arrived in a very static way, a document, a PDF, a thing that sat there.
What he wanted instead was a dynamic platform. Not just a report generator, but a place where the findings that are critical to an organization live right alongside all the other risks that are getting reported. That single design decision, findings from a pen test sitting in the same store as findings from everything else, is the seed of everything the product later became.
What still gets him excited, he says at 1:21, is helping people fix the right things, helping them avoid getting breached, and helping them know exactly what an attacker can do in their environment.
How the product evolved
Miessler says he has been aware of the product for quite a while and asks how much it has changed, particularly given what is happening now with AI attackers. Is it moving toward remediation in addition to reporting? Because the great thing about PlexTrac back in the day, he says, was that it helped with the part of the pen test that was the worst for the tester. Then he says the line every pen tester has said out loud at least once:
I always loved testing and I always hated reporting.
DeCloss confirms the expansion. Reporting is still the roots and still a very important piece of the puzzle: helping testers stay focused on more testing and less reporting is still core product. But four more layers have grown on top of it.
- Stage 1Pen test reporting. The origin. Kill the static document, kill the copy and paste, let testers spend their hours testing instead of writing. Still core product today.
- Stage 2Centralize every finding source. Vulnerability scanning, application scanning, code scanning, all of it pulled into one platform, so the pen test findings become an overlay on top of the whole vulnerability management picture rather than a separate PDF nobody opens.
- Stage 3Risk scoring and prioritization. Score every finding against the context of the environment, because the blue team problem is not "I have no findings," it is "everything is labeled critical by Nessus and by my pen testers, so which one do I fix first?"
- Stage 4Workflow automation for tracking and remediation. The track in PlexTrac. Visibility on who is doing what on the fix side, bidirectional ticket sync, triggers, assignment, escalation.
- Stage 5AI on the lifecycle. Today it writes findings and reports from the context of the finding. Next it moves into recommendation and automation across remediation and prioritization. Announcements teased for "the near future."
The blue team pain point he names at 2:44 is the crux of the whole interview. A defender opens the console and sees tons of issues. They are all critical. They are all stated critical by Nessus and by the pen testers. So how does anyone know which ones to fix first? Because, as he puts it:
At the end of the day, we don't have a problem of sourcing findings. It's more where are the right ones to be fixing now that'll make the biggest impact on our business.
So the expanded product does three things: aggregate the data, provide a mechanism for scoring and prioritizing findings within the context of the business, and then facilitate workflow automation around tracking and remediation.
On that last one he tells the story that explains the company name. The track in PlexTrac has always been about tracking and remediation, and it comes from a specific failure mode he lived through as a consultant: he hated delivering a pen test report and then coming back a year later because nobody had fixed anything. Some of that is a procedural breakdown, he says with a certain generosity. They did not copy and paste the right data into the spreadsheet or the ticketing system. Or, less generously, they did not care about it at all. Either way, the fix is the same: permanent visibility into who is doing what on the remediation side, and as little friction as the platform can strip out.
What AI is actually changing in the wild
Miessler asks the AI question directly at 4:06. One of the narratives is that AI is letting people attack faster. What is DeCloss seeing in findings, what are Customers reporting back, and how is PlexTrac helping?
DeCloss's answer is notably unhyped, and it is worth quoting because it cuts against the way most vendors answer this question. As an industry, he says, we do not have a problem identifying more issues. Yes, AI is accelerating attacks and providing new attack vectors and new mechanisms. But the attacks still tend to be exploiting some of the same things, just at a faster pace, alongside identifying more issues.
Which means the defender's question does not change at all. It is still "what are the most important things I should be fixing first." That is the problem PlexTrac is trying to solve and, he says, does help solve: giving you a better perspective on the prioritized list. And then the sentence that becomes the through line of the last third of the conversation:
That list is going to continue to grow deep, and AI will only continue to make that list bigger.
He also draws a clear product boundary here, twice in the conversation: PlexTrac does not do automated remediation. The goal is to provide as much recommendation and automation around that process as possible, and to integrate with the products that actually perform the fix. Miessler agrees it gets a little sticky when vendors try to own the whole thing.
Context driven risk scoring
Miessler picks up the word "context," which he calls one of his favorite words, and asks how the business context gets factored into the prioritization.
DeCloss frames PlexTrac's approach against the industry norm. A lot of products and companies provide their own proprietary risk scoring mechanism, a black box that hands you a number. PlexTrac took a different approach. There is a default out of the box calculation using the things commonly associated with a risk score: asset criticality, the location of the asset, the type of data it processes, and so on. But then the flexibility goes back to the Customer and to the user.
You have full control over how those factors get weighted and what additional criteria you want to add, so you can say, in effect, this is how we structure our data, these are the fields that matter most to us, and we want those fed into the risk score. Full flexibility over what criteria go into the algorithm and what weights they carry. The result, in a phrase DeCloss likes, is an objective overlay applied in a somewhat subjective manner.
And it does not have to be enterprise wide. You can break the calculation down by department or division. Keep a default enterprise wide risk calculation, then give an R&D department that needs different scrutiny its own scoring algorithm. Miessler reads it back as Customers having a decent amount of control over the schema for the ratings, customizable per group, which is exactly right, and then asks the question that turns the interview into a demo: are you able to pull that up?
The walkthrough: findings, instances, and the number 56
At 7:15 the screen share starts and DeCloss is inside the exposure management module.
He explains the data model first, because everything downstream depends on it. There are findings and there are instances of findings. Think of a finding as "we have SQL injection." Each reported occurrence of it is an instance of that finding. That distinction is what lets one vulnerability class carry twenty three thousand real world occurrences later in the demo.
In the left hand column of the table sits the risk score. The finding at the top is labeled critical by its source, which he believes was Nessus, or Tenable. But its PlexTrac risk score reads 56, which lands in the high band, not critical, because it is being calculated by the risk scoring algorithm attached to it. And this particular algorithm is scoped to the accounting department specifically.
He opens the calculation to show what composes it. Instance severity and asset criticality are the two most heavily weighted inputs. Then a couple of others he set up for this example: is there a known exploit for it, and has it been used in a known ransomware campaign. That is the whole idea of contextual scoring in one screen: the scanner says critical in the abstract, the algorithm says high for this department on this asset, and the second number is the one that should drive the work queue.
Clicking into the algorithm itself opens the editor. Here you can see how points accumulate within each weighted category, and you can build a very robust set of rules. You can change the weights themselves. And you can add additional variables, which come in three families:
- Asset related variables. If you tag all of your assets, or want to base scoring on their physical location or asset type, that is available.
- Finding and instance variables. Anything about the finding itself. Did it have a CVSS score of four? You specify what score bands map to what criteria. Tagging works here too.
- Custom fields. Any custom field you already use inside PlexTrac is exposed to the risk scoring engine. DeCloss says they see Customers lean on this a lot, because organizations tend to have custom fields they already use across their entire environment on assets or findings, and those are exactly the fields that encode the business context nobody else knows about.
The daily view: dashboard, assets, and the ticketing sync
Miessler asks what a Customer actually sees day to day. When you land on PlexTrac you get the general dashboard: open findings, that kind of thing, plus assets with critical findings. Drill into exposure management and you can pivot the whole view around assets. What assets live in my environment. How many findings does each one carry. DeCloss picks one asset and reads off its findings, their status, and who is assigned to what. The same drill down works at the finding and instance level.
Then he opens the integrations filter and the list of vulnerability scanning vendors PlexTrac ingests. But the more interesting integration, and the one he clearly cares about, is the ticketing side: Jira, ServiceNow, Azure DevOps, and those are bidirectional syncs.
The reason he cares is workflow, not features. If your IT operations group or one of your development teams has to leave their tooling and come into a security platform to update a ticket, they will not do it, and the security team ends up chasing them. So the ticketing and remediation process happens inside the fixer's own workflow, and that data syncs back into PlexTrac and automatically updates the status of the finding.
Miessler reads it back: so they can close an item inside their own workflow without having to come back to the dashboard. Exactly, DeCloss says. You are not interrupting anyone's workflow, and as the security team you still have a centralized view of everything that has happened and who responded to it.
He clicks a finding to show its full status history, and apologizes that it is a demo environment so it has been used a lot. He also notes you can define custom sub statuses to match your own process, things like "ready for retest" or "ready for review."
The workflow automation engine
DeCloss then opens the workflow automation engine, which reinforces the same mechanism from the other direction. Inside the reporting module, if a pen tester reports a critical finding, then the moment it is published it can be immediately assigned to somebody.
Miessler asks who these people are: someone on a dev team, someone on a security team? Both, DeCloss says. In this example you can assign to a specific person, send it to Slack or Microsoft Teams, say into an open escalations channel, send emails, or immediately create tickets directly in the target system such as ServiceNow. The flexibility is deliberately wide so you can automate as much as you possibly can. And then the boundary again: they do not do the remediation itself, but they integrate with the products that do. Miessler: "that gets a little sticky when people try to do the whole thing."
Miessler asks whether triggers can fire off criteria like department plus severity. The trigger fires off the finding itself, DeCloss clarifies, and then you can layer criteria on top: if it is also assigned to this person, then go do these things. The base events are finding created, finding edited, or finding status changed, including a change to a specific sub status.
Libraries: write ups and narratives
Miessler spots the questionnaires, playbooks, and libraries in the navigation and asks what they are. DeCloss starts with libraries, which are pre built content and sit closer to the original reporting product.
The pitch is aimed squarely at anyone who has written a pen test report. You already have your standard way of writing up SQL injection. You already have your standard cross site scripting narrative. In PlexTrac those are write ups, stored in the write ups database. PlexTrac ships multiple sources of them and plenty of Customers bring their own.
The obvious benefit is reuse. The less obvious benefit is the one DeCloss actually emphasizes, and it is a genuinely good point that only a practitioner would raise: it reduces bleed over. When you copy and paste from one report into another, information unique to the previous Customer comes along for the ride. Every consultant has had that heart stopping moment of finding another client's hostname in a deliverable. A write ups database removes the copy and paste step entirely, so the bleed over cannot happen.
The narratives database is the same idea for the prose sections of a report: the executive summary, the methodology, the scope, all the parts that are written rather than enumerated. Pre built, templatable, so you can define the ten sections of the report you always want and have them appear.
Two Customers, one platform: internal teams and consultancies
Looking at the libraries, Miessler has a realization on camera. He had been thinking about internal use: a big corporation or a mid size company using this to explain findings to internal Customers, manage remediation, prioritize vulns. But the libraries make him see the other market. This could also be a pen test company, with multiple testers doing tons of work for different clients who want very different deliverables. Some Customers want cold, hard, direct truth in no more than three pages. Others want a giant twenty page verbose thing.
One hundred percent, DeCloss says. PlexTrac supports consulting teams working with many clients. The demo environment is an enterprise demo, so the containers are labeled departments, but in a consultancy those are the equivalent of a client, and you write a report for that specific client. Equally, a large enterprise with an internal pen testing team can write its own pen test reports in the platform and bring all its other findings together in the same place. Those are the two use cases the product supports:
- an internal enterprise team with both exposure management needs and pen test reporting needs
- consulting firms and managed services firms supporting multiple Customers, doing pen testing, vulnerability management, and sometimes the tracking and remediation on the Customer's behalf
The multi Customer story has a nice concrete detail. Tool integrations can be configured per Customer. If you are a managed services firm with ten Customers, one runs Tenable, one runs Qualys, one runs Rapid7, and you integrate with each Customer's tool set separately, centralizing all that data while keeping it isolated per Customer.
Playbooks: MITRE ATT&CK engagements that write their own report
This is the section where Miessler audibly changes posture, and it is the best few minutes of the demo.
Playbooks, also known as runbooks inside PlexTrac, support executing an engagement built off MITRE ATT&CK. You can build test plans against different frameworks, but ATT&CK was the primary use case. DeCloss says suppose we want to emulate APT28, opens it, finds it only has three procedures loaded in this environment, and switches to FIN6 for a better example.
Starting the engagement, he selects who it is being run against, and the playbook lists all the procedures that will be tested and executed, giving you a view of your coverage within the ATT&CK matrix itself. Then the testing team works the list. For each procedure they record the red team outcome, was it successful, and the blue team outcome, did the defenders log it, detect it, block it, or see nothing at all. You can attach all kinds of detail. And at any point you can mark a procedure done and say this becomes a finding, at whatever severity.
Miessler stops him:
Oh, okay. So this is a big deal. So you kind of casually mentioned this is also a methodology, like a workflow system for managing what needs to be done in a test.
Exactly. You build the template from whatever framework you use, MITRE or otherwise, it holds all the steps so the team can collectively make sure they cover everything, and the output flows into the report.
DeCloss adds the second purpose. It is a methodology for the testing team, and it is also a data collection surface for the blue team. The defenders can come in and say they did not see this activity, or that they went back and did have the logs, or that there was no evidence at all. That can be added during the engagement, or afterward, since the red team may not want to reveal everything until the report is delivered.
Miessler names the third audience: auditors and Customers who simply want evidence that the work was done, with logs of what happened and when. Especially, he says, for purple team engagements, where the whole question is what did they do and what did we do. Yep, DeCloss says, this really serves that purpose.
Then the payoff. When you are done you submit the engagement, and PlexTrac creates a report using whatever templates you chose. He flips to the reporting module and there it is: all the findings, including the one procedure he converted to a finding, sitting where it belongs, with all the procedures still shown underneath. The narrative sections came in automatically from the template chosen at the start of the engagement. Now the tester tweaks them, cleans them up, adds whatever else is needed, and has a full fledged report.
Miessler's reaction is the honest one:
This is hours and hours of manual work.
"Every single time you execute it," DeCloss says.
And then, in a moment of unusual candor for a product demo, DeCloss points out that the finding he just created is scoring low, not critical, even though he labeled it critical as the pen tester. Why? Because it fell to the default equation and he never assigned an asset to it, so none of the contextual criteria were met. He shows the miss rather than hiding it. Miessler's read is fair: it is good to have that kind of flexibility. It is also the clearest possible illustration of what contextual scoring does. Sever the finding from its business context and the context aware number has nothing to work with.
| Module | What it actually does | Who it is for |
|---|---|---|
| Exposure management | Findings and instances from every source, contextual risk score in the left column, asset pivot, priorities grouping, integrations filter. The demo environment holds 23,000 finding instances. | Blue team drowning in "everything is critical" |
| Reporting + libraries | Write ups database (reusable SQL injection, XSS write ups, no copy and paste bleed over) and narratives database (executive summary, methodology, scope as pre built sections). | Testers who love testing and hate reporting |
| Playbooks / runbooks | Engagements built on MITRE ATT&CK procedures. Red team outcome and blue team outcome per procedure, coverage view, mark a procedure as a finding, submit and it generates the templated report. | Red, blue, purple teams, and auditors wanting evidence |
| Questionnaires | The longest standing module. Custom questionnaires for any compliance framework, for example an annual PCI self assessment. Mark non compliance, add notes, complete questions, deliver results as findings. | Internal audit and GRC, or assessment consultancies |
| Assets | Everything that arrived from a manual pen test entry, an Nmap scan, a vulnerability scanner, or the API from something like ServiceNow. Asset type, criticality, tags, data owners, and the metadata that feeds scoring. | Everyone, because scoring depends on it |
| Workflow automation | Triggers on finding created, edited, or status changed. Actions: assign to a person, post to Slack or Teams, send email, create the ticket in ServiceNow or Jira or Azure DevOps. Bidirectional sync back. | Security teams who are tired of chasing IT |
Questionnaires
Miessler apologizes for digging around the interface and asks about questionnaires. DeCloss calls it one of the older, longer standing modules. It was built for custom questionnaires tied to any compliance framework, or just general questionnaires. It has some similarities to runbooks but is not identical.
His example: an annual PCI self assessment questionnaire. He starts one. Miessler reads it back as making sure certain things are tested according to a standard you have to follow, which DeCloss confirms, and adds it serves two audiences: your internal audit or GRC team, and firms doing questionnaire based assessments rather than pure pen testing. He admits the demo example is weak because it only has three questions, but shows the mechanics: mark them as not compliant, add notes, mark the question complete. It is another workflow around executing a questionnaire and delivering those results as findings, which is the important part, since it lands the compliance output in the same store as everything else.
Twenty three thousand instances
Miessler asks whether they are seeing a lot of use and interest around this because more vulns are coming in. Yes, definitely, DeCloss says, and then starts to "land the plane on the demo side" with the number that makes the whole argument concrete.
In this demo environment alone there are 23,000 instances of findings.
That is the number the risk score exists to defeat. Sorted by contextual risk, the ones scoring 100 are the ones you go fix first. And beyond individual scores, the priorities capability lets you group instances and assets together to get a more holistic view: within this set of instances and assets, prioritize these things above all else.
Everything around the prioritization and management of findings, he says, is where they see the most demand and the most help needed, and that is what they are aiming to continue supporting: prioritization, understanding who is doing what, and automating as much of the remediation lifecycle as possible.
Asset management
Miessler notices the asset management and asks about it. These are all the assets that have come in, DeCloss says, whether reported manually in a pen test, produced by pen test tooling such as an Nmap scan, delivered by a vulnerability scanner, or brought in through the API from something like ServiceNow.
Inside an asset you get the metadata you would expect. You can set the asset type and the criticality, which is the input that flows straight back into the risk scoring capability. You can tag assets and assign different data owners. The intent, in his words, is to standardize and centralize as much of this information as possible.
What is coming next
At 21:53 Miessler asks what DeCloss is excited to work on next, and guesses he will be in Vegas. He will: Black Hat, for sure.
On the roadmap, the theme is AI across the lifecycle: more recommendations, more automation around the lifecycle, with things to be shared in the near future. The organizing frame he reaches for is Gartner's, which he calls the CTM lifecycle, covering the identification, validation, prioritization, and mobilization of findings. That is the main focus.
What exists today is the natural first application. PlexTrac's current AI capability helps testers write their reports, which he notes is a very natural fit for LLMs, since the model has the context of the findings and reports are structured prose. What is coming is AI supporting more automation in the remediation lifecycle workflow and in prioritization.
Miessler makes the point that ties the roadmap back to the demo: even with AI, you cannot do much unless you have the data. PlexTrac already has the connectors and the pre built plumbing that gets the data in one place, which is what makes the AI layer possible at all.
The Hacker News article, Mythos, and the vulnpocalypse
Miessler says he saw DeCloss on The Hacker News recently, and asks what that was about.
The article, DeCloss says, laid out a bit of their take on the Mythos and vulnpocalypse discussion, and he encourages everyone to read it. The premise is the one he has been circling all conversation. As everyone knows, AI is going to keep accelerating the ability to find more things. The solution is not to try to prevent that. It is to let AI help the defenders, and he splits that into two moves.
Move one: push AI upstream into the SDLC. His stated premise is that moving AI into the software development lifecycle is the natural fit for most people. If you have a Mythos class model sitting in your pipeline, then great, you should be producing far less vulnerable code right out of the gate. Fix it before it ships and it never becomes a finding.
Move two, because move one will not arrive fast enough. That upstream shift, he concedes, is not going to proliferate in the near term. So the next primary milestone is using AI to help defenders prioritize the findings they already have. AI will keep finding more and more, and it will go faster. If you can make sure you are prioritizing the things that will actually get you breached, that is always going to be the most important thing.
Known knowns
Miessler distills it: it is easy to get over excited about new tech, but what is the new tech actually doing? In this case it is finding way more stuff, and you still have the central problem of what do I fix.
Exactly, DeCloss says, and that closes the loop back to why he got into pen testing in the first place. How are breaches actually happening. What is actually going to get people breached. Understanding what attackers can genuinely do in your environment. So be proactive about that, do the testing, try to identify it.
Then the strategic point, and it is the most quotable idea in the interview. We have so much more information available to us now than we did fifteen years ago. I know what attackers can do in our environment. That is a known known. They will always come up with other things, but for the most part we know a lot of what they can do. We just have to identify how to prevent it.
So focusing on the known knowns is always going to be just as important as trying to stay ahead of the next zero day. Staying ahead of the zero day is always going to be a lot more difficult. But if you have a handle on how you are reducing that backlog of known knowns, that is where the bulk of the work needs to be done.
Miessler agrees and puts the honest version of it plainly: we are not in a situation where we have fixed everything and everything is clean, and now we just need to worry about zero days. We are still sitting on a giant backlog of stuff that has not been fixed, and we need a priority for it. One hundred percent, DeCloss says.
They close on Vegas. Miessler will be at Black Hat, hopes to see him there, and says they will get the link added. Great to chat.

Where it stands
This is a sponsored vendor conversation. The video description links a PlexTrac demo through an Unsupervised Learning tracking link, roughly two thirds of the runtime is a product walkthrough, and DeCloss is the founder. None of that makes the observations wrong, but it is the frame, and Miessler does not pretend otherwise: he asks DeCloss to pull the product up on screen and then digs around the interface himself.
The core argument holds up independently. The claim that discovery is no longer the bottleneck is being validated in real time. FIRST forecast roughly 66,000 CVEs for 2026 after 2025 finished at a record 48,185, and NIST reclassified tens of thousands of backlogged CVEs as "not scheduled" for analysis. Anthropic's Claude Mythos Preview, the model DeCloss references, was announced in April 2026 as capable of autonomously discovering and exploiting zero days, and Palo Alto Networks reported finding 75 vulnerabilities in its own products in a month, roughly seven times its usual rate, after adopting frontier security models. Against that backdrop, "the list will keep growing and you still have to pick" is not marketing, it is arithmetic.
Two small corrections for anyone taking notes. DeCloss says "the CTM lifecycle" that Gartner deemed; the framework he is describing is CTEM, Continuous Threat Exposure Management, whose stages include the prioritization, validation, and mobilization steps he names. And "Hacker News" here means The Hacker News, the security news publication where PlexTrac runs expert insight pieces and won two 2026 Cybersecurity Stars Awards, not the Y Combinator link aggregator. The specific vulnpocalypse article is never named on air, so treat the two linked PlexTrac bylines in the Resources below as the closest published statements of the position rather than as the exact piece.
The one claim worth holding lightly is the implied efficacy. Contextual, Customer weighted risk scoring is a genuinely better idea than sorting by raw CVSS, and DeCloss argues that case well, including the moment where he lets his own demo score a critical finding as low. But the quality of the output depends entirely on whether an organization has actually tagged its assets, set criticality honestly, and maintained the custom fields the algorithm reads. A configurable scoring engine sitting on top of unmaintained asset data will produce confident numbers that are just as arbitrary as the ones it replaced. He says as much without quite saying it: assign no asset, get a meaningless score.
