How to prevent an AI agent from executing an infinite loop?

Exogram acts as an Execution Authority Layer that monitors intent and rate limits tool calls, intercepting unmonitored loop cost overruns before they execute.

How do you stop LLM indirect prompt injection API access?

A Semantic Firewall decouples the LLM's non-deterministic text generation from the actual tool execution. Exogram inspects the intent of the payload, blocking unauthorized state mutations triggered by prompt injection.

What are deterministic guardrails for LLM tool calls?

Deterministic guardrails are strict, code-level policies (like capability downgrading) that cannot be bypassed by natural language. Exogram wraps every tool call in these policies to prevent execution drift.
