ThunderGuard sits between the world and your agent. It intercepts prompt injection, jailbreaks, tool misuse and data exfiltration in real time — before they ever reach your model.
One URL change. No SDK, no code in your repo. Live in under 10 minutes.
Traditional firewalls inspect packets. Nobody is inspecting the language going into your agent — and language is now the attack surface.
Malicious text buried in user input, emails or scraped pages rewrites your agent's instructions and turns it against you.
Role-play framing, encoding tricks and multi-turn manipulation push your agent to say and do things you never approved.
Attackers chain your agent's own tools — email, payments, file access, code execution — into actions with real-world cost.
System prompts, API keys and customer data quietly extracted from your agent's context, one clever question at a time.
ThunderGuard is a security proxy. Your traffic flows through it, gets inspected in milliseconds, and clean requests pass straight through to your model provider.
Replace your model provider's base URL with your ThunderGuard endpoint. Keep your own provider API key.

Inline detection and blocking of the OWASP LLM Top 10 attack patterns, tuned for agents with tools.
We attack your agent before hackers do — hundreds of adversarial probes, with a report of what broke and how to fix it.
Block rate, threat types and attack sources updating in real time. Know you're under attack while it's happening.
No SDK inside your codebase, no agents on your servers. One URL change, works with any stack.
Slack and email alerts on attack spikes and new threat types, with full request context for triage.
You choose fail-open or fail-closed. If ThunderGuard is ever unreachable, your agent behaves exactly as you decided.
