Vigil Guard
What Vigil Guard is
Vigil Guard is a paid AI Detection & Response platform that monitors prompts, model responses, and agent actions in real time. Its detection system evaluates interactions through six parallel branches and can return ALLOW, SANITIZE, or BLOCK. Coverage includes direct and indirect prompt injection, jailbreaks, data leakage, malicious instructions, semantic drift, secrets detection, and output guardrails. The platform can redact more than 20 personally identifiable information entity types before data reaches a model, using replacement, hashing, or masking configured per API key. It is offered as an API, browser extension, Linux deployment, and self-hosted installation. Enterprise can run with Docker Compose on Linux x86_64 and operate air-gapped without external calls or telemetry. The extension supports Chrome and Microsoft Edge. Integrations include Splunk, QRadar, Sentinel, Elastic SIEM, n8n, LiteLLM, and a Python SDK with REST access. Each installation includes a seven-day trial with full functionality and no usage limits.
