Security report
Your score and findings appear here after you scan.
A one-off scan isn't runtime protection.
Vigil checks every live prompt, retrieved document and tool call your agents handle — and blocks attacks before they reach the model. Free Starter plan includes 1 Agent, 1,000 logs/month, and 7-day retention (plus a 14-day full Team trial, no credit card required).
