Our take— Claude wins
Based on our comparison of published pricing, features, and compliance data, Claude scores 8.9/10 to Windsurf's 7.6/10. Claude pulls ahead with SOC 2 certification and multi-factor authentication. Windsurf stays close but doesn't lead on any single attribute here. Pick Claude if SOC 2 certification matters; Windsurf is the pick if it doesn't.
