Why Remediation Stalls: The IT and Security Handoff Problem

Key Takeaways

• Remediation rarely stalls because nobody is working. It stalls in the handoff, when a finding moves from a security dashboard into an IT ticket queue without the context IT needs to act on it.
• Severity scores like CVSS alone lead teams to patch the wrong things first. Pairing CVSS with EPSS and asset criticality tells you what’s actually being exploited and what actually matters to your business.
• Nearly half of enterprise vulnerabilities stay open past the twelve month mark, and a chunk of those are rated high or critical.
• Legacy systems, missing patch testing, and emergency patch cycles all slow remediation down in different ways, and each needs a different fix.
• Verifying a fix worked matters as much as applying it. Plenty of tickets get closed as “resolved” without anyone confirming the vulnerability is actually gone.

A vulnerability sits open for 90 days. Then 120. A security analyst has flagged it three times. IT says it’s in the queue. Nobody is lying, and nobody is lazy. The fix is just stuck in the space between two teams that are looking at the same problem through two different lenses.

That gap is where most remediation actually dies. Not in the scan. Not in the report. In the handoff.

Where The IT And Security Handoff Actually Breaks

Security finds the vulnerability. IT owns the system it lives on. Somewhere between those two facts, a lot goes wrong.

Security teams often work off a scanner and a severity score. IT works off a ticket queue, a change calendar, and a production system they’re responsible for keeping up. When a finding crosses from one world into the other, it frequently loses the context that made it urgent in the first place. That’s the structural root of it, not a personality clash between two departments.

Severity Scores Don’t Tell The Whole Story

CVSS tells you how bad a vulnerability could be. It doesn’t tell you how likely it is to actually get used against you. A vulnerability with a CVSS score of 9 sitting on a server behind layers of internal controls can matter far less than a CVSS 6 sitting on something exposed to the internet. That mismatch explains why do security teams patch low risk vulnerabilities while missing critical ones, and it’s a pattern that shows up in nearly every backlog sorted by severity alone.

EPSS fills the gap CVSS leaves open. It estimates the probability that a given CVE will be exploited in the next 30 days, based on real world exploit activity instead of theoretical damage. Research from the vulnerability scoring community has found that fewer than 5% of published CVEs are ever exploited in the wild, even though most teams still sort their backlog by severity alone. Combine CVSS with EPSS and asset criticality, and the list of what to fix first gets a lot shorter, and a lot more accurate.

The Ticket Lands Without Context IT Can Use

IT isn’t resisting the fix. IT is resisting a ticket that doesn’t tell them enough to act on, which is really the answer to why do IT teams resist vulnerability remediation requests. A finding that shows up with no business context, no exploit evidence, and no sense of urgency relative to everything else on IT’s plate gets pushed to the bottom of the pile, every time.

The teams that get faster remediation give IT more than a CVE number. Every ticket that moves fast tends to answer a few questions up front:

• Which asset is affected, and what does it actually support?
• Is this vulnerability being exploited anywhere right now?
• What happens if nobody touches it this week?
• Is there a safer interim fix if a full patch isn’t ready?

Without that, security is asking IT to trust a severity number. IT usually needs more before it reprioritizes its own week, and that hesitation is often mistaken for pushback when it’s really a request for buy-in that never fully arrived. That’s also why do security teams struggle to get remediation buy-in from IT in the first place: the ask shows up without the reasoning attached.

Why Vulnerabilities Persist For Months Without Being Fixed

Once a finding clears the handoff, it still has to survive contact with reality. That’s where legacy systems, testing gaps, and patch timing take over as the main blockers.

Research from Edgescan has found that close to half of enterprise vulnerabilities remain unpatched after twelve months, and 17% of those are rated high or critical severity. That’s not a detection failure. Detection already happened months earlier. It’s a remediation failure, and it usually comes down to a short list of repeatable causes:

• Legacy systems. Older systems carry technical debt that turns every patch into a risk calculation. Why do legacy systems create persistent vulnerability management challenges comes down to this: a fix that takes ten minutes on a modern stack can require a full regression test on an application nobody fully understands anymore. Teams end up choosing between an unpatched vulnerability and a broken production system, and unpatched usually wins by default.
• Missing patch testing. Patching without testing is how outages happen. Testing without enough environments or time is how backlogs grow. This is how does lack of patch testing slow vulnerability remediation plays out in practice: most organizations don’t have a clean staging environment for every system a patch touches, so testing gets squeezed into whatever window is available, which pushes the actual fix further out.
• Emergency patch cycles. An out of band critical patch doesn’t wait for the next release. It interrupts sprints and forces engineers to context switch off planned work, which is exactly why do emergency patch cycles disrupt development operations the way they do. Do this often enough, and engineering starts treating every “emergency” patch with less urgency, because the label has been overused.

How Risk Based Prioritization Closes The Remediation Gap

None of this gets solved by tightening SLAs on a broken process. A faster deadline on bad prioritization just produces faster escalations, not faster fixes.

Risk based vulnerability management works because it changes what gets asked of IT in the first place. Instead of “patch everything rated critical,” the model becomes “patch what’s exploitable, exposed, and sitting on something that matters.” That combines a few signals into one prioritized list instead of five disconnected ones:

• CVE data and CVSS severity
• EPSS exploit probability
• The CISA Known Exploited Vulnerabilities catalog
• Asset criticality
• Current threat intelligence

Secure.com’s own breakdown of EPSS in practice walks through exactly how that scoring combination plays out on a real backlog. Why do organizations overspend on vulnerability remediation without risk reduction? Usually because they’re spending effort proportional to volume, not to risk, and those two numbers rarely line up.

Prioritization only solves half the problem, though. The other half is knowing where things stand and knowing a fix actually landed:

• Tracking gets messy fast. A shared spreadsheet works fine until three teams are updating it at different speeds, or a system in the scanner doesn’t match the same system in the CMDB. That’s why do organizations fail to track remediation progress effectively so often: once the data disagrees with itself, nobody trusts the tracker anymore. How to track vulnerability remediation progress across teams really comes down to one requirement above all others, a single source of truth that both security and IT actually check.
• “Resolved” isn’t proof. A ticket marked resolved isn’t the same thing as a vulnerability that’s actually gone. Why do teams struggle to verify that vulnerabilities were properly fixed usually traces back to skipped retesting: plenty of fixes get closed without confirming the exploit path is actually closed, which means the same CVE can quietly reappear months later. How to verify vulnerability remediation effectiveness after patching really just means retesting the exact path that was flagged, not just confirming the patch installed.

Running Remediation Like A Program, Not A Fire Drill

The organizations that stop drowning in backlog treat remediation as a workflow with steps, not a queue of alerts to react to.

• Meet engineering where it already works. How does vulnerability management connect to Azure DevOps for remediation is one of the biggest unlocks for engineering-heavy teams: route prioritized findings straight into the same board developers already live in, instead of a separate security portal nobody checks. A finding that shows up as a ticket in the tool engineering already uses gets fixed faster than one buried in a report.
• Don’t wait on zero days. No patch doesn’t mean no options. How to handle zero day vulnerability response without available patches usually comes down to compensating controls: blocking a specific attack path at the network layer, disabling a vulnerable feature, or adding detection rules for known exploit patterns. The goal isn’t to wait for the vendor, it’s to shrink the exposure window in the meantime.
• Run it like a sprint. How to run a vulnerability remediation sprint with engineering teams starts with treating it the way engineering treats any other sprint: a fixed scope, a clear owner per item, and a demo at the end that proves the fix actually worked. Bundling related fixes together, instead of sending one ticket per CVE, also cuts down on the context switching that wears out engineering’s patience with security requests.

How to close the loop between vulnerability detection and remediation is really the question underneath all of this. Detection, prioritization, assignment, the fix itself, and verification all have to feed back into each other, or the same problems keep resurfacing under new CVE numbers.

Conclusion

Remediation doesn’t stall because security or IT stopped caring. It stalls because the handoff between them is missing the one thing that would make prioritization obvious: shared context. Fix that handoff, and the backlog stops being a mystery and starts being a manageable list.
