Vigile Sentinel — Runtime Phone-Home Detection

Beta

Static scanning catches what's in the code. Sentinel catches what the code actually does on the wire. It monitors MCP server network behavior in real-time to detect C2 beaconing, data exfiltration, DNS tunneling, and covert channels that static analysis misses.

C2 Beaconing

Catches tools phoning home on a schedule

Credential Theft

Detects SSH keys & tokens leaving your machine

DNS Tunneling

Spots data hidden in DNS queries

Sentinel is in Beta. Detection patterns are continuously improving. Sentinel supplements — not replaces — your existing security practices. Terms of Service.

Frequently Asked Questions

Everything you need to know before getting started.

Is the CLI scanner really free?

Yes, completely free and always will be. The CLI scanner includes 220+ detection checks across MCP, skill, Sentinel, and backend analysis, plus trust scoring and typosquatting detection. It requires no account or API key. Run npx vigile-scan anytime.

What does Sentinel detect that static scanning doesn't?

Static scanning analyzes code before execution. Sentinel monitors what happens at runtime — actual network connections, data exfiltration attempts, C2 beaconing patterns, and DNS tunneling. A malicious MCP server might look clean in code but phone home when it runs.

What's the difference between Pro and Pro+?

Pro gives you Sentinel runtime monitoring with behavioral pattern detection — perfect for individual developers securing their MCP setup. Pro+ unlocks advanced detection patterns (DNS tunneling, C2 beaconing), longer monitoring sessions (30 min), 10 concurrent servers, and support for teams running production systems.

Can I try Sentinel before subscribing?

Running vigile-scan --sentinel on the free tier shows you the upgrade prompt with a preview of Sentinel's detection categories. Subscribe to Pro ($30/mo) to unlock runtime monitoring.

Do you offer annual billing?

Yes. Pro Annual is $300/year ($25/mo effective, saving $60/yr vs monthly) and Pro+ Annual is $900/year ($75/mo effective, saving $300/yr vs monthly). Annual subscriptions renew yearly and can be canceled anytime.

Can I upgrade from Pro to Pro+ later?

Absolutely. Upgrade anytime from your account page. Billing is prorated so you only pay the difference for the rest of your billing cycle.
