BreachBeacon

BreachBeacon is a web app (with optional browser extension) that continuously monitors your third-party vendors for early signs of compromise and security regression. It combines traditional security checks (domain, certificate, DNS, email security posture, exposed services, leaked credentials) with AI-assisted analysis of vendor trust signals (security pages, SOC2/ISO claims, incident disclosures, status pages, and changelogs) to produce a simple, defensible risk score and a “what changed” timeline. Instead of sending endless questionnaires that vendors ignore, you get lightweight, automated evidence and alerts when a vendor’s posture worsens—new exposed ports, DMARC misconfigurations, suspicious subdomains, newly leaked employee credentials, or sudden policy changes. The product is realistic: it won’t magically see inside a vendor’s network, but it will catch many common external indicators that correlate with real incidents. It’s designed for small security teams who need leverage, not more busywork.
