Detection Engine Updates Version 2.164
Release Date: May 25, 2026
This release of the GitGuardian detection engine adds six new detectors — for Authentik API Token, Pagar.me Encryption Key, Adobe Refresh Token, LiteLLM API Key, brapi.dev API Key, and Open VSX Access Token — together with new checkers for Google OAuth2 Keys and a new analyzer for Adafruit IO API Key.
Notable precision improvements (measured on internal benchmarks):
snyk_key: precision raised from ~40% to ~90%.finicity_authentication_keys: precision raised from ~67% to ~98%.hunter_api_key: precision raised from ~9% to ~100%.datadog_api_credentials: significant reduction in false positives.github_access_token: significant reduction in false positives.heroku_platform_key: significant reduction in false positives.
