AWS ACTIVATE MEMBER · AGENT-NATIVE SECURITY GATEWAY

zn stops
prompt injection.

Sacrificial protection for AI agents: deterministic rules locally in <0.1 ms, Galvanize-60M CPU inference at 11.52 ms p50 (sub-15 ms), and zero data retention (ZDR) on paid tiers.

WHY ZN

Sacrificial protection

Like a sacrificial shield for your AI systems, zn absorbs and neutralizes prompt injections before they ever reach your models or tools. Every tool call is inspected in real time.

HOW WE’RE DIFFERENT

Three reasons teams switch to zn

No anonymous checkmarks. Every claim links to something you can verify.

Open core, zero dependencies

MIT SDKs with no third-party code plus the Rust core on GitHub. Runs offline with no vendor lock-in — unlike proprietary APIs you cannot inspect or self-host.

Browse the source

Published gates, frozen benchmarks

Galvanize-60M reports a 1.00% tool FPR across 9/9 certified industrial gates (vs 90.33% for ProtectAI), 91.60% Deepset OOD recall and 77%-97% needle recall over 23,699 public vectors. Honest note: 9 locales with published evaluations, not 100+ claimed languages.

Pricing FAQ

What happens after the 48h trial?

The 48h trial includes 100 standard and 25 Galvanize-60M neural calls. Upgrade to Hobby at $19/mo (100,000 calls/mo); your API keys stay valid.

Need more calls?

Overage packs start at $9 for 30,000 calls and never expire.

Do you store my prompts?

No. Evidence is a SHA-256 hash plus metadata with 90-day retention. See /privacy.

Can I cancel anytime?

Yes. Cancel anytime through Polar self-service.
