Not verified. We could not confirm an ISO/IEC 27001 certification for Perplexity.

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: Not verified; No public ISO/IEC 27001 certification was confirmed. Request evidence from Perplexity AI, Inc. if this is a procurement requirement.
SOC 2: Confirmed; Perplexity AI, Inc. also reports a SOC 2 attestation, which can complement but does not replace ISO scope evidence.
Default data training: Opt-out required; On consumer/free/Pro accounts an 'AI data retention' setting is on by default and can be used to improve models; logged-in users can opt out in Settings > Account, but logged-out users cannot.
Business-tier training: No by default; Perplexity Enterprise Pro and the Sonar API operate under Zero Data Retention and state customer/enterprise data is never used to train models.

Practical risk: On consumer plans data is used to improve models unless you turn off the default-on 'AI data retention' toggle, and reporting alleges Perplexity shared conversational data with ad/tracking platforms (incl. in Incognito).

How to make a decision

Check the precise account tier, written contract and intended data before approving Perplexity. 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.
