Cerberius helps developers make decisions about who's interacting with their apps — and how. Whether it's a new signup, a login, or a prompt to an LLM, we offer signal that helps you understand what's coming in.

IP Risk Lookup: Understand where connections originate, and flag known proxies, bots, and abusive traffic before it hits your backend.

Email Verification: Catch disposable or risky emails early. Verify that addresses are real, active, and not from throwaway domains.

Prompt Safety Check: Scan LLM prompts before they reach your model. Catch injections and manipulations that could alter output or behavior.

More is coming: We are committed to expanding our set of tools and are already working on new capabilities to support developers building secure systems.

Cerberius is available with a free tier — no time limits, no credit card required. And if you're building something and want a deeper look, we're offering a limited number of beta access slots with expanded usage.
