VendorSentry

VendorSentry is a web app (with optional browser extension) that continuously monitors your SaaS vendors for security drift and risky changes that commonly precede incidents. Instead of generic questionnaires, it pulls evidence from what vendors actually expose: security headers, TLS posture, DNS changes, exposed admin portals, leaked credentials tied to vendor domains, public breach signals, and status-page anomaly patterns. It then maps findings to your internal vendor list, assigns a practical risk score, and generates a short, actionable remediation request you can send to the vendor (with evidence attached). The product is intentionally lightweight: it won’t replace full GRC platforms, but it will catch the “quiet” issues that procurement reviews miss and that attackers exploit. Expect some false positives early; the value comes from trend detection, change alerts, and fast triage rather than perfect certainty.
