SOC 2 for LegalTech

Legal technology vendors face some of the strictest confidentiality requirements in enterprise software. Law firm IT teams and General Counsel offices conduct thorough security reviews — and attorney-client privilege creates an additional overlay that most SOC 2 auditors aren't familiar with.

The Confidentiality trust service criteria are non-negotiable for legaltech. Law firms will ask specifically how opposing clients' data is isolated, whether AI models trained on case data could surface privileged information, and how you ensure that eDiscovery evidence chains maintain integrity throughout processing.

Data residency is a common blocker. Many Am Law 200 firms require that all document processing occur in US-based infrastructure and that subprocessors are contractually restricted from accessing the data. This must appear in your SOC 2 system description and be supported by vendor agreements.

Legal clients will review your penetration test report personally and ask follow-up questions about findings. The bar for remediation timelines is higher than in other industries — critical findings are expected to close within 30 days, not the next sprint.

Common legaltech SOC 2 gaps: no documented data classification scheme distinguishing privileged vs. non-privileged content, audit logs insufficient to reconstruct data access in eDiscovery scenarios, and sub-processor agreements that permit data use for model training.
