Dublin Startup Jentic Launches Free Permission Firewall to Stop OpenClaw Credential Leaks

What Happened

Dublin-based startup Jentic released Jentic Mini on March 25, 2026 — a free, open-source, self-hosted permission firewall for OpenClaw agents. According to The New Stack and Arabian Reseller, Jentic Mini sits between agents and the APIs they connect to, holding credentials centrally so the agent never sees them directly. The tool enforces fine-grained permissions and provides a single kill switch that shuts down all agent data access instantly.

Jentic Mini gives developers access to an AI-curated catalog of more than 10,000 APIs and workflows while establishing "no-go zones" that prevent agents from accessing sensitive files like .env or banking URLs without explicit manual authorization. The tool is available on GitHub and the Jentic website at no cost.

Why It Matters

The credential leakage problem has been one of OpenClaw's most embarrassing security gaps — agents routinely surface passwords and API keys in their output, and the 135,000+ exposed instances documented by SecurityScorecard make this a live vulnerability at scale. Jentic Mini takes a practical, middleware approach rather than trying to fix OpenClaw's architecture: by ensuring the agent never holds credentials directly, it eliminates the most common exfiltration vector without requiring changes to OpenClaw's codebase. The single kill switch is particularly valuable for enterprise teams that need an emergency stop mechanism. Unlike SecureClaw's audit-focused approach or OpenShell's sandboxing strategy, Jentic targets the specific credential-handling weakness that security researchers have flagged most urgently.

What's Next

Jentic has positioned this as a gateway to its broader API management platform. Expect to see similar middleware solutions emerge as the OpenClaw security ecosystem matures from detection-only tools toward active prevention layers.
