TL;DR: 26% of CISA KEV vulnerabilities were fully remediated in 2025, according to Lansweeper's blog post and the Verizon 2026 DBIR. Incomplete inventory and ownership data turn remediation into a reconciliation problem before any fix can land.
Editorial analysis by NHI Mgmt Group, based on content published by Lansweeper: “What Is IT Remediation? Definition, Types, and Process”.
Key questions
Q: Why do remediation efforts stall when asset records are inconsistent?
A: Remediation stalls because inconsistent asset records prevent teams from knowing which hosts, applications, owners, and versions are actually affected.
Q: What is the difference between remediation, mitigation, and acceptance in vulnerability management?
A: Remediation fully fixes the vulnerability so the weakness is removed.
Q: How should security teams prove that a vulnerability has really been remediated?
A: They should require evidence that the vulnerable condition is no longer reachable or exploitable, not just that a ticket is closed.
Practitioner guidance
- Establish verified asset identity before assigning remediation Reconcile scanner output, inventory records, and business ownership so every finding points to one change target.
- Route findings by accountable asset owner Attach an owner to each asset class and make the ticket follow that ownership record instead of a manual handoff.
- Treat verification as a mandatory closure step Recheck the affected asset after the fix and keep the finding open until the exposure is no longer observable.
Bottom line: Remediation fails most often at the mapping stage, where teams cannot connect a finding to one verified asset and owner.

Remediation is an asset-data problem before it is a patching problem. Security teams often treat remediation as a speed issue, but the real friction is usually identity resolution for assets. If the finding cannot be matched to a verified machine record, the fix cannot be targeted or evidenced. That makes remediation dependent on governance over asset identity, not just vulnerability tooling.
A few things that frame the scale:
- The average time to mitigate a leaked secret is 36 hours, highlighting the operational burden of manual remediation processes, according to the 2024 State of Secrets Management Survey.
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to the State of Secrets in AppSec.
A question worth separating out:
Q: How do mean time to remediate and reopen rate help security teams?
A: Mean time to remediate shows how long it takes to close findings after detection, while reopen rate shows how often supposedly fixed issues return. Together they reveal whether patching, configuration changes, and validation checks are actually holding, or whether teams are only creating temporary closure in the ticketing system.
