AI gateway security requires evaluation beyond convenience, says developer guide.

A developer-focused guide advises that AI gateways, often adopted for operational convenience, become critical security boundaries by handling all AI traffic. It distinguishes between three gateway types: AI, MCP, and agent gateways, each protecting different aspects of AI interactions. The guide highlights indirect prompt injection as a key threat, especially for agents using external tools, and recommends rigorous testing of security features. It suggests creating a test harness to evaluate a gateway's ability to block malicious prompts while allowing legitimate traffic.
