Is Claude safe to use with company data?
Claude is safe for company data on Team or Enterprise plans, where Anthropic does not train on your inputs by default and offers a DPA — consumer Claude.ai accounts are not appropriate for regulated data without those controls.
Does Claude train on your data?
Anthropic does not train its models on business/commercial inputs by default, and offers controls on consumer tiers. Always confirm the setting for the plan you use.
The enterprise option
Claude for Work (Team/Enterprise) adds SSO, admin controls, and contractual data-handling commitments suitable for sensitive data.
Data processing agreement (DPA)
Anthropic provides a DPA for commercial customers — needed when employees enter personal data under GDPR/UK GDPR.
The real risks for Anthropic customers
- Consumer accounts lack the contractual and admin controls regulated industries require.
- No org-level visibility into which staff paste sensitive data.
- Data-handling settings differ by plan and must be verified.
What never to paste into Claude
- Customer or employee PII
- Financial or payment data
- Health information (PHI)
- Proprietary code or secrets
- Confidential contracts
