GuardianShield runs on your own machine — the client starts it, so there is no endpoint to ping. 82 installs a week from pypi. Last commit 3 Mar 2026.
AI security layer: code scanning, PII detection, prompt injection, secrets, CVEs
Today is the operative word: we check GuardianShield every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
GUARDIANSHIELD_PROFILE (Default safety profile (general, education, healthcare, finance, children)), GUARDIANSHIELD_AUDIT_PATH (Path to the SQLite audit database), GUARDIANSHIELD_DEBUG (Set to 1 for debug logging).
The author declared them in the registry entry; get the values from the project itself.
