Cybersecurity insights, threat intelligence updates, and vulnerability management best practices from the SYRN team.
Since 11 September 2026, manufacturers must report any actively exploited vulnerability within 24 hours through ENISA's platform. What this obligation changes, and does not change, for the way you prioritize patches.
We took the 598 CVEs that threat intelligence reports attribute to a named actor or tool, and looked at their CVSS scores. Nearly six in ten are not critical, and that share runs from 0% to 100% depending on the group. Above 9, CVSS describes a shape of attack more than a severity: the unauthenticated RCE.
Is SYRN a vulnerability scanner? No. A scan is a snapshot that hands you 200 critical CVEs per cycle without telling you which ones are actually being exploited. Here is how a scanner and SYRN complement each other inside a CTEM practice.
Heartbleed, Log4Shell, Citrix Bleed: we assume a flaw with a name must be worse. But cross-referencing 994 named vulnerabilities against 361,589 CVEs flips that. A name tells you almost nothing about severity. It tells you the flaw will be exploited.
We analyzed 355,000 CVEs and CISA's entire KEV catalog. Patch Tuesday is a decoy: the real disclosure peak is Wednesday. A (tongue-in-cheek) guide to when not to take time off in vulnerability management.
Nearly 50,000 CVEs in 2025, 70,000 expected in 2026, yet less than 1% are actually exploited. Why CVSS and EPSS are no longer enough to decide what to patch.
