Runtime security that decides what your AI agents are allowed to do
Wrap agent tool calls and get a typed decision - allow, block, redact or hold for review - before the tool actually executes, based on actor, role, route and typed inputs.
Screen user input, fetched web pages, API responses and tool output for hostile instructions before anything reaches the model context.
Detect and strip names, addresses, national IDs, bank and card numbers before they reach model context, logs or third-party tools, with optional in-process local detection.
Bot protection, WAF rules, rate limiting, signup form protection and email validation to keep public endpoints and signup flows clean.
