Claude Cowork Security: Enterprise Risks, Vulnerabilities & Best Practices

Claude Cowork is an agentic desktop AI tool that can access local files, execute commands, automate browser tasks, connect to enterprise systems through MCP servers, and run scheduled workflows using a user’s existing permissions. Its direct-action capabilities can improve productivity but introduce risks involving sensitive-data exposure, prompt injection, unmonitored tool use, malicious configurations, credential theft, and compliance gaps, particularly because Cowork activity is not currently included in Anthropic’s audit logs, Compliance API, or data exports. The material advises organizations to avoid using Cowork for regulated workloads involving HIPAA, PCI-DSS, or similar requirements until audit coverage is available, and to adopt a layered governance model ranging from disabling Cowork entirely to permitting only organization-approved plugins, connectors, and domains. Recommended controls include enterprise SSO and SCIM, managed device policies, MCP allowlists, restrictions on sensitive files and risky commands, network egress limits, incident-response procedures, and operational monitoring through OpenTelemetry, although it does not replace compliance-grade auditing. It also presents MCP gateways and LLM proxies, including MintMCP products, as tools for centralized authentication, access control, runtime monitoring, and audit trails across Cowork and other AI clients.
