Is ChatGPT ISO 27001 certified?

Yes

OpenAI · AI assistants

Yes. OpenAI is ISO/IEC 27001 certified for ChatGPT, the international information-security management standard.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

ISO/IEC 27001: Confirmed; OpenAI reports ISO/IEC 27001 certification. Ask for scope and current certificate dates before treating it as supplier assurance.
SOC 2: Confirmed; OpenAI also reports a SOC 2 attestation, which can complement but does not replace ISO scope evidence.
Default data training: Opt-out required; On free/Plus consumer ChatGPT, conversations are used to improve models by default unless you turn off 'Improve the model for everyone' in data controls.
Business-tier training: No by default; OpenAI does not train on inputs or outputs from ChatGPT Team, ChatGPT Enterprise, or the API platform by default.

Practical risk: Consumer/free ChatGPT uses your chats for training unless you proactively disable it, so staff pasting work data into personal accounts can leak it into model improvement.

How to make a decision

Check the precise account tier, written contract and intended data before approving ChatGPT. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
