Lakera
A security guard for your AI — blocks prompt attacks, jailbreaks, and harmful responses before they cause damage
Using Lakera is like hiring a vigilant security guard for your shop who quietly checks every person coming in and every package going out, stopping trouble before it reaches the floor.
Lakera is a safety layer that sits between your AI app and the people using it. It watches every message going in and every response coming out, catching things like sneaky attempts to trick the AI, leaked sensitive information, or unsafe content. Companies use it so their chatbots and AI features don't get manipulated, embarrass the brand, or expose private data. Think of it as a bodyguard that makes sure your AI behaves the way you intended.

Guardrails AI focuses on checking that your AI's answers follow your own rules like format and accuracy, while Lakera focuses more on blocking outside threats like prompt attacks and jailbreaks, so the choice really depends on whether you're worried about bad outputs or bad actors.
