Capsule Security provides a runtime security and governance platform for AI agents operating across third-party environments such as Copilot Studio, Agentforce, and ServiceNow. The product discovers agents, inventories their tools, data access, and actions, and gives security teams a consolidated view so they can see which agents exist, what they can reach, and how they behave. It enforces real-time guardrails to block prompt injection, tool abuse, and sensitive data exfiltration, while aligning controls with frameworks like NIST AI RMF, ISO 42001, MITRE ATLAS, and the EU AI Act. The platform integrates with existing SIEM and IAM stacks so SecOps can monitor agent activity, investigate anomalies, and respond without introducing a separate operational silo. Capsule emphasizes purpose-built runtime AI models and kernel-level observability (e.g., tracing system calls and resource usage) to turn low-level behavior into human-readable timelines, enabling security teams to approve policies, stop rogue agent actions quickly, and prove compliance around high-risk AI automations.
