Logs from an access proxy are more than network chatter. They are evidence. They show which systems vendors touch, what data moves, and when. For vendor risk management, these logs are essential. Without them, you are blind to what third parties actually do inside your environment.
A strong vendor risk management process uses logs from the access proxy to confirm that vendors follow agreed policies. You can detect unsafe patterns: unexpected endpoints, bursts of traffic at odd hours, or API calls outside scope. This raw telemetry lets you enforce contracts in real time, not just on paper.
Centralizing logs from every access proxy gives you a single audit surface. You can feed them into SIEM tools, alerting pipelines, or automated compliance checks. You can compare vendor activity against allowlists and geofencing rules. You can flag data exfiltration before it becomes a breach.
