Practical security insights and product updates from the team building safer, simpler key management for modern APIs.
CNCERT flagged prompt injection in AI agents as a national security risk. The Telegram link preview exfiltration technique is real. Here's how a credential proxy makes it structurally impossible.
Run API Stronghold as a credential proxy for OpenClaw so agents never hold real API keys. Fake keys in, real credentials injected at the proxy, nothing reaches the LLM context window.
Environment variables work fine solo. They fail in production. The Phantom Token Pattern gives agents fake tokens that proxy to real credentials at runtime.
Zero trust says never trust, always verify, least privilege. Most AI agent deployments violate all three. Here's how a credential proxy closes the gap without rewriting your stack.
