Vendor Evidence Drift API: the certification that quietly covers less
An API that compares two snapshots of a vendor’s compliance evidence and reports scope changes, subprocessors, policies, SLAs, and reproducible risk scores.
Field notes
The service compares retained vendor-evidence snapshots rather than merely displaying a vendor’s current trust page. Its illustrative six-month comparison catches three materially different changes: availability disappears from a SOC 2 scope, a Brazilian subprocessor is added, and the uptime SLA moves from 99.95% to 99.90%. The homepage says the demo uses the paid endpoint’s engine, while the advertised free tier allows 150 evidence checks per month.
