ABA Model Rule 1.6 — Duty of Confidentiality

Model Rule 1.6 imposes a duty on lawyers to make reasonable efforts to prevent the inadvertent or unauthorized disclosure of client information. When engaging technology vendors, firms must document that they assessed the vendor's security controls. ThirdProof produces this documentation in language defensible before state bar disciplinary committees.
