Cloudflare's WriteGuard addresses agent security risks

Cloudflare has developed a new security system called WriteGuard to address a critical vulnerability in agent deployments. The primary risk identified is not prompt injection, but rather an agent performing authorized actions at high speed under a human's name without oversight. WriteGuard acts as a server-side interception layer, classifying calls based on their potential impact and attributing actions to specific agent identities to prevent misuse. AI
