About Capsule Security
Capsule Security provides a runtime security platform for AI agents. It monitors agent behaviour continuously and intervenes when activity looks anomalous or unsafe. The company sells to security, compliance and AI governance teams in enterprises that use AI agents. Its platform works as an independent layer, so customers do not need to change agent code or architecture. The platform covers discovery, observability, runtime protection and identity control. It can discover agents across home-grown systems, SaaS platforms and endpoints without installing agents. It maps how agents interact with tools, data and actions, and it enforces policies before actions run. It also offers white-box red teaming to find weaknesses in agent logic and prompts. Capsule supports agents built on platforms such as AWS Bedrock, Azure AI Foundry, Google Vertex AI, Claude Code, Cursor, GitHub Copilot, ChatGPT Enterprise, Microsoft Copilot Studio and Salesforce Agentforce. It has integrations for the Claude Platform, Claude Code hooks and Claude Code OpenTelemetry.
