Best for: Developers shipping AI agents to production

Visit Secra

Secra sits between your AI agent and the language model it uses. Each incoming prompt is scanned for threats such as prompt injection, attempts to hijack the agent's persona, or tricks to leak data, and harmful ones are stopped before they cause damage.

It is added with a Python client in a couple of lines of code, and scanning is designed to be very fast. A free allowance of 100 credits per month is included, with no card required.
