Navigating the AI Security Landscape

Why are there so many categories?

The AI security market is fragmenting. Input/Output Guardrails (like Lakera) focus on sanitizing prompts.Agentic IAM (like Keycard) focuses on identity.Agent Runtime Security (like GuardionAI) unifies these by protecting the entire execution lifecycle of autonomous agents.

How to choose?

If you have a simple chatbot, look for Guardrails. If you are deploying autonomous agents that use tools (APIs, DBs), you need Runtime Security with strong tool authorization. For enterprise visibility without blocking, look at Observability platforms.
