> Sentinel Gateway — jaisimha18-nebula-ninjas. Use this tool when you need to secure internal servers with zero-trust access control and real-time threat detection, solving problems of tool-poisoning and metadata drift. The Sentinel Gateway takes in agent tool calls and outputs a cryptographic provenance ledger, providing a secure interface for monitoring and verifying tool activity. It is ideal for use cases requiring robust security and compliance in sensitive environments.
