AI agents are no longer experimental - they’re operational.

Proofpoint has acquired Acuvity, integrating AI-native detection models, runtime enforcement, and governance controls into its security stack.

Key implications for defenders:
• Context-aware AI interaction monitoring
• Control across endpoints, browsers, and AI infrastructure
• Mitigation of prompt injection & model manipulation
• Governance for enterprise AI deployment
• Unified protection for human + agent workflows

Agentic risk modeling is now a core requirement.
