OpenPostern
Track third-party security threats with prioritized alerts and risk scores
OpenPostern monitors third-party vendors and alerts you to real, actionable risks. It pulls daily data from NVD and CISA KEV, checks SSL/TLS certificates and DNS/HTTP security, and scans security news with AI to find issues affecting your exposure. It combines signals into a 0–100 vendor risk score with clear next steps. You can start in minutes by searching its vendor catalog—no integrations or security team needed. Designed for SMBs, it filters noise so you only act when a vendor issue demands attention.
