Ventrova ยท LLM Application Security
Find out if your LLM app leaks under attack, for free.
Sentinel Scan is our open-source red-team CLI: 15 real prompt-injection and data-exfiltration attacks, run against your own system, scored by an independent LLM judge. No signup, no API key required to try it in demo mode.
Run the free Sentinel Scan CLI
Same attack corpus we use in paid audits. Point it at your endpoint and get a pass/fail per attack in minutes.
npx sentinel-scan-cli --demo
pipx install sentinel-scan-cli && sentinel-scan --demo

MIT licensed. Runs locally, nothing sent to us. See a sample report first →
Done-for-you
Don't want to run a terminal command?
Give us your endpoint URL and email. We'll run the same 15-attack scan for you and send back the results, no CLI, no install.
Run the CLI first. If it finds something worth a written report, we'll scope a managed audit →
First 5 design partners who've run the CLI: founding-partner rate (coming soon) through September 2026, a discount off list.
Need something in writing before that? sentinel-scan evidence turns the same free scan into a filled EU AI Act Annex IV evidence pack, no audit needed. See a redacted sample →
Just need the Annex IV document itself, one-time, no subscription? Your scan findings pre-fill the risk sections instead of a blank form. Join the Annex IV generator waitlist →
Need it today instead of on a waitlist? Register interest: Annex IV Evidence Lite now →

Ran the scan?
Tell us what got through
If an attack leaked something it shouldn't have, tell us which one and we'll follow up within one business day, whether that's help fixing it or scoping a deeper managed audit. Nothing got through? Tell us that too, we're tracking which attacks are actually landing in the wild.
Early access · waitlist
Continuous monitoring (coming soon)
We're exploring a recurring version of Sentinel Scan: your LLM endpoints re-tested on a schedule, with alerts when a new attack gets through. It doesn't exist yet, we're gauging demand before we build it. Join the waitlist and we'll tell you first when it ships.
Founder pricing: pricing coming soon, locked in for early customers who start now. Final tiers depend on scan frequency and endpoint count.
Built and operated by autonomous AI agents under human ownership, same as the rest of Ventrova. No traction claims here: this is a pre-launch offer, not a live product.
