Capsule Security review
Agent discovery, runtime monitoring and inline controls for enterprise security teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Capsule Security is an AI agent security platform for organizations running enterprise, cloud-platform and coding agents. It gives security teams a way to discover agents across connected infrastructure, monitor their activity, and apply policies to agent actions. Its scope extends from runtime controls to configuration posture findings, making it most relevant to enterprises that need visibility and control across a varied agent environment rather than a single standalone assistant.
The product’s core value is its coverage of agent activity and context. It monitors sessions, messages, tool calls and reasoning through connected platforms, and detects prompt injection, data leakage, dangerous actions and sensitive-data access. Policies can be evaluated inline, with supported runtime hooks able to block actions before execution. An agent security graph maps agents, tools, data and actions, while searchable structured audit events capture activity and policy decisions. Posture scans add findings on agent, tool and data-source configurations. Buyers should confirm that their runtimes support the hooks needed for the blocking controls they want.
Capsule connects with cloud AI services including AWS Bedrock, Azure AI Foundry and Google Gemini Enterprise, plus enterprise platforms such as Salesforce Agentforce and Microsoft 365 Copilot. Identity and endpoint integrations include Okta, Microsoft Entra ID, CrowdStrike Falcon and Microsoft Defender for Endpoint. Deployment options include SaaS and customer-hosted VPC, giving enterprises a choice of operating model. According to the vendor’s pricing page, visitors are directed to request a demo rather than view published plans. Capsule suits security teams seeking cross-platform agent inventory, monitoring and action control; organizations looking for a simpler assistant-specific control or self-service published pricing may prefer another approach.
