Trust & security
Security

Enterprise plan includes data privacy agreements, SSO, and admin controls. Anthropic publishes a usage policy and data handling documentation.

Microsoft 365 Copilot maintains data within your Microsoft 365 tenant. SOC 2, ISO 27001, and GDPR compliant. Data does not leave Microsoft 365 security boundary.

Privacy notes

Free plan data handling differs from enterprise arrangements. Review Anthropic's privacy policy before uploading sensitive documents. Enterprise contracts include stricter protections.

Copilot has access to your emails, documents, and Teams messages within your tenant. Review permission settings carefully. Enterprise version maintains data within Microsoft 365 environment.

Cons
  • Integration ecosystem is narrower than ChatGPT
  • No built-in image generation
  • Voice input not available on all platforms
  • Free plan limits can be restrictive for heavy users
  • Microsoft 365 Copilot business plan expensive at $30/user/month on top of existing licensing

  • Less capable for creative and coding tasks than specialised tools
