Arcjet is a runtime security platform embedded in AI code to detect prompt injection and authorize agent actions.

Arcjet provides runtime security building blocks that developers can embed directly into their AI applications. By calling these security functions right before an action happens, the platform enables real-time protection. It offers essential capabilities including prompt injection detection, agent tool call authorization, sensitive data redaction, and protection against bots and abuse.

// ANALYSIS

Embedding security directly into AI application code is becoming a necessity as agents take on more autonomous actions and access sensitive systems. By shifting security left into the runtime environment, Arcjet allows developers to enforce context-aware policies, such as validating specific tool calls before execution, rather than relying on blunt network-level defenses.

–Context-aware security is superior for protecting agent tool calls.
–Embedding at runtime minimizes latency for real-time AI interactions.
–Addresses the critical need for prompt injection defenses in production AI apps.
