The REST containers have no authentication, the project states no SLA or support, and it covers personal data only, with no prompt injection or content moderation checks.\n\n## Before you call either\n\n### Google Cloud Model Armor\n\n1. Create one template per location you call from. A template in us-central1 doesn't answer on the europe-west2 endpoint\n2. Call `sanitizeUserPrompt` before the model and `sanitizeModelResponse` after, and read filterMatchState on both\n3. Treat EXECUTION_SKIPPED as unchecked, not clean. It means the input went over the filter's 65,536-token cap\n4. Pin the template to the Stable alias and move off v1 and v2 before 17 December 2026. In asia-northeast3, v1 stays the Stable version\n5. Retry 500, 502, 503 and 504 with truncated exponential backoff, and keep fan-out under the 1,200 queries a minute shared by the project\n\n### Presidio\n\n1. Install from PyPI or pull images from ghcr.io/data-privacy-stack. The mcr.microsoft.com/presidio-* images are no longer updated\n2. Download a spaCy model (python -m spacy download en_core_web_lg) before the first `AnalyzerEngine()` call, or use the Docker image\n3. Send both text and language to `/analyze`. A request missing either returns HTTP 500 with a JSON error field\n4. Pass entities and score_threshold to limit results. Many country-specific recognisers are disabled by default and need enabling in the registry YAML\n5. Keep the containers on a private network or behind your own authenticating proxy. They accept any caller\n\n## Questions\n\n### Which is better for AI agents, Google Cloud Model Armor or Presidio?\n\nGoogle Cloud Model Armor scores 77.9 (BB) on agent readiness against Presidio's 66 (B), and leads in 6 of 7 scored categories. Presidio leads on payments \u0026 pricing.\n\n### Can an agent call Google Cloud Model Armor and Presidio without installing anything?\n\nGoogle Cloud Model Armor has a hosted endpoint at https://modelarmor.{location}.rep.googleapis.com/v1/projects/{project}/locations/{location}/templates/{template}:sanitizeUserPrompt. No hosted endpoint is listed for Presidio.\n\n### Are Google Cloud Model Armor and Presidio open source?\n\nNo open-source release is listed for Google Cloud Model Armor.
