Key Points
- CISA’s Known Exploited Vulnerabilities (KEV) catalog identifies vulnerabilities that are actively being exploited, providing a stronger remediation signal than severity scores alone.
- NinjaOne Vulnerability Management now surfaces KEV status alongside CVSS scores to help IT and security teams prioritize vulnerabilities based on real-world risk.
- Risk-based remediation enables organizations to focus patching efforts on actively exploited vulnerabilities rather than relying solely on vendor-assigned severity ratings.
- Automated workflows can accelerate remediation for KEV-listed vulnerabilities and support faster response to emerging threats.
- KEV intelligence strengthens audit, compliance, cyber insurance, and executive reporting by providing defensible, threat-informed remediation decisions.
- As AI accelerates vulnerability discovery and exploitation timelines, organizations will increasingly need risk-based prioritization to manage growing remediation backlogs.
Every month, hundreds of vulnerabilities receive a severity rating. Dozens of those are flagged as the most serious possible. For IT and security teams, this creates a familiar and frustrating problem. When everything looks urgent, nothing is truly prioritized.
That’s where the Known Exploited Vulnerabilities (KEV) catalog comes in. It tells you what’s actively under attack. NinjaOne Vulnerability Management now surfaces KEV status directly alongside CVSS scores, so your team has both signals in one place.
What is the CISA KEV catalog?
The security industry created KEV because severity alone isn’t enough. The KEV catalog is maintained by the Cybersecurity and Infrastructure Security Agency (CISA). It’s a curated, continuously updated list of vulnerabilities that have been confirmed as actively exploited in the wild. They’re known to be actively dangerous, not just rated as critical by a vendor.
A vulnerability scoring 9.8 on CVSS that has never been observed in active exploitation is lower priority than one scoring 8.1 that appears on CISA’s KEV catalog and is actively being used by attackers. Traditional severity-based patching prioritizes the first. Risk-based remediation prioritizes the second.
This isn’t a hypothetical scenario. It plays out constantly. A significant portion of KEV-listed vulnerabilities have CVSS scores below 9.0, and many high-scoring vulnerabilities never see active exploitation. Severity and exploitability are related, but they are not the same thing.
Federal agencies are required to remediate KEV-listed vulnerabilities within defined timeframes, and the catalog has quickly become the most reliable real-world exploitation signal available to IT and security teams.
How KEV works in NinjaOne Vulnerability Management
KEV intelligence is now integrated directly into the NinjaOne Vulnerability Management workflow. When scanning your environment, NinjaOne enriches every vulnerability finding with both CVSS severity and KEV status, giving you a complete picture of each vulnerability’s real-world risk.
This means your team can prioritize remediation based on active exploitation, not just vendor ratings. You can configure automated workflows to accelerate patching for KEV-listed vulnerabilities, separate from your standard severity-based policies. And you can demonstrate to auditors, insurers, and executive stakeholders that your remediation decisions are grounded in real threat intelligence, not arbitrary severity thresholds.
For MSPs managing multiple clients, KEV intelligence adds another layer of confidence to remediation reporting. When a client asks why a particular vulnerability was prioritized, you have a clear, defensible answer backed by CISA data.
The bigger picture
The timing of this release matters. AI-powered vulnerability discovery initiatives, including Anthropic’s Mythos and OpenAI’s Daybreak, are expected to dramatically increase the volume of vulnerabilities discovered and compress the time between discovery and active exploitation. Organizations will face growing remediation backlogs and increasing pressure to act faster on the vulnerabilities that matter most.
In that environment, the ability to distinguish between a vulnerability that is severe and one that is actively under attack becomes even more valuable. KEV intelligence gives your team that distinction today, and positions you to manage the accelerating pace of vulnerability discovery as it unfolds.
Enterprise customers and compliance frameworks increasingly expect risk-based prioritization, not just patch compliance. KEV intelligence is one of the clearest signals available for meeting that standard and demonstrating that your security program is focused on real-world risk.
