Constellation Gate AI ("Gate AI") is a drop-in security gateway that sits between your AI agent and the model, screening every request for prompt-injection attacks, credential/PII leaks and hijacked tool calls. It also compresses and caches prompts to cut token usage without changing outputs, and records an immutable, blockchain-backed audit trail. Built for teams running AI agents or coding tools that need security, compliance and cost visibility.Editor's note: Listed from public information — hands-on review pending. We never sell rankings.
