About IT Security
What this is for.
Three questions, in order. What happened. Does it affect you. What should you do.
You tell us what you run. Every advisory is then matched against it, and the answer comes with the reasoning — which product, which version, which range the vendor published.
It is not a scanner and not a managed service, and it does not inspect your network. Every verdict is computed from what you enter and what vendors and agencies have published, and every fact on an advisory page is linked to the record it came from: NVD, CISA’s Known Exploited Vulnerabilities catalogue, FIRST’s EPSS, and the vendor’s own advisory.
