Frequently Asked Questions
- Q: Is ISO/IEC 27001 certification sufficient for a legal AI vendor to handle privileged client data?
- ISO/IEC 27001 is a strong baseline indicator but not a complete answer. It addresses general information security management rather than the specific confidentiality obligations governing attorney-client privilege. Firms should also assess the vendor's data processing agreements, data residency practices, whether client data is used for model training, and compliance with applicable privacy regulations such as GDPR.
- Q: How often must an ISO/IEC 27001-certified organization be audited?
- Initial certification involves a full audit. Thereafter, the certified organization must undergo annual surveillance audits and a full recertification audit every three years. Firms should request current certificates rather than relying on historical certifications that may have lapsed. --- *Last reviewed: 2026-05-19 by LawyerAI Editorial Team.*
