Q&A

What exactly is Capsule Security?

Capsule Security is an AI agent runtime security platform. Its primary function is to prevent AI agents from either malfunctioning or going rogue. It does this by providing real-time monitoring during runtime and promptly intervening when any anomalous or potentially unsafe activities are detected. The tool is also designed as an independent security layer and does not require any modifications to the existing systems including code, agents, or architecture.

What are the core features of Capsule Security?

The core features of Capsule Security are Runtime Monitoring and Runtime Intervention. In Runtime Monitoring, Capsule Security provides live visibility into the activities of agents allowing the detection of issues as they occur. Under Runtime Intervention, it acts to prevent unsafe actions from execution including potentially risky commands, unsafe tool usage, sensitive data exposure, and unexpected action chains.

How does the Runtime Monitoring feature of Capsule Security work?

Capsule Security's Runtime Monitoring feature provides live visibility into AI agent activity. It continuously tracks the behavior, decisions, and execution paths of these agents. This level of detailed tracking enables it to detect issues as they occur in real-time. It is designed with the concept of 'deep observability', allowing for continuous insight into how AI agents function, and facilitating faster investigation and governance.

How does Capsule Security's Runtime Intervention function prevent unsafe actions?

Capsule Security's Runtime Intervention function acts to prevent unsafe actions from being executed. When it detects potentially risky commands, unsafe tool usage, sensitive data exposure, or unexpected action chains, it intervenes and blocks these activities. This capability operates in real-time, preventing incidents without slowing down the agents or engineering teams involved.

Does Capsule Security require modifications to existing code, agents, or architecture?

No, Capsule Security does not require any modifications to the existing code, agents, or architecture. It is designed as an independent security layer. This design ensures that it is always relevant and works with any framework, tool, or environment, thereby eliminating the need for rewriting agents, redesigning workflows, or sacrificing autonomy.

What types of AI agents can Capsule Security secure?

Capsule Security can secure a broad range of AI agents. These range from Developer & Endpoint Agents like local agent frameworks and tools, to SaaS & Enterprise Agents such as Microsoft Copilot Studio agents and Salesforce Agentforce. Essentially, any AI agent capable of taking actions can be secured by Capsule Security.
