Vigil Guard is an AI Detection & Response platform for monitoring prompts, model responses, and agent actions as they occur.
What Vigil Guard is
Vigil Guard is an AI Detection & Response platform for monitoring prompts, model responses, and agent actions as they occur. Its detection stack evaluates interactions through six parallel branches and returns an ALLOW, SANITIZE, or BLOCK result. Coverage includes direct and indirect prompt injection, jailbreaks, data leakage, malicious instructions, semantic drift, and secrets. The platform can redact more than 20 types of personally identifiable information before content reaches a model, with replacement, hashing, or masking configured for each API key. It is offered through an API, browser extension, Linux deployment, and self-hosted installation. The Chrome and Microsoft Edge extension monitors shadow AI usage. Enterprise deployment uses Docker Compose on Linux x86_64 and can run fully air-gapped without external calls or telemetry. Listed integrations include Splunk, QRadar, Sentinel, Elastic SIEM, n8n, LiteLLM, and a Python SDK with REST access. Every installation has a seven-day full-function trial. Pricing is on request, with no free plan.
