> Monitor vendor security signals and organize evidence for risk reviews

OpenPostern helps businesses monitor the security signals associated with their software vendors. Teams select vendors from a catalog, then review information drawn from vulnerability feeds, known exploited vulnerability listings, infrastructure checks, and security news. Scores and alerts help prioritize which changes merit further investigation.

The service includes checks for certificates, DNS configuration, and HTTP headers, with notification channels and historical views varying by plan. Teams can export vendor information and produce reports for internal reviews or insurance discussions. A free tier covers a small vendor list, while paid plans expand monitoring and collaboration. Its reports organize evidence for review without guaranteeing a vendor's security.
