Client-data segregation, e-discovery readiness, wire-transfer-fraud defense, 24/7 SOC, and cyber-insurance-aligned controls. ### AI tools quietly waiving privilege Harvey, CoCounsel, Lexis+AI, M365 Copilot, ChatGPT. Every prompt sent to a vendor model that retains or trains on data is a potential privilege event. ABA Formal Opinion 512 (July 2024) and the wave of state bar opinions made the duty explicit; most firms don't have the operational controls to match. ### Client privilege at risk in every email A misrouted reply, a misfiled attachment, or a phished assistant can disclose privileged communication and create a malpractice claim. Reactive controls don't survive a state bar inquiry. ### Matter-data sprawl across SaaS Documents end up in OneDrive, Dropbox, NetDocuments, iManage, email attachments, and Slack DMs. Without classification and retention controls, the firm cannot answer 'where is everything for matter X?' on the day it matters. ### Ransomware against billable hours Law firms have been a top-five ransomware target since 2019. Attackers target case-management systems and accounting because downtime translates directly to lost billable hours and missed filing deadlines. ### E-discovery and litigation hold When opposing counsel issues a hold, the firm has to preserve relevant ESI across mail, file shares, mobile, and SaaS. Most firms only learn whether their controls work when sanctions are on the table. ## What we deliver for legal teams ### Privilege-preserving AI governance ABA Op 512 operationalized: AI vendor inventory, BAA-equivalent data handling reviews, prompt protocol per practice group, M365 Copilot configuration that respects matter walls, and an AI policy your malpractice carrier will accept.

We operationalize ABA Formal Opinion 512 and applicable state bar guidance through an AI vendor inventory, BAA-equivalent data-handling reviews, prompt protocols per practice group, Microsoft 365 Copilot tenant configuration that respects matter walls, and an AI policy your malpractice carrier will sign off on. The full 90-day playbook lives in our AI Governance for Law Firms resource. ### Does EFROS understand attorney-client privilege? Yes. Our engagement model preserves privilege at the technical and procedural level. Labels follow documents across systems, audit logs are configured to avoid privileged-content exposure, and incident-response procedures pause before any communication that might waive privilege so your general counsel or outside counsel can review. ### Can EFROS support our case-management platform? Our engineers have delivered operations across iManage, NetDocuments, Clio, MyCase, PracticePanther, Smokeball, and several custom matter-management systems. Backup, DR, and security controls tune per platform; integrations with billing and email follow your firm's existing workflows. ### How do you handle a litigation hold? We work with your designated litigation-hold officer (typically the managing partner or general counsel) to issue holds across email, file shares, mobile, and SaaS. Hold scope is documented, custodians notified, and preservation status is reportable on demand for opposing counsel or the court. ### What about cyber-insurance requirements? Most cyber-insurance carriers now require MFA, EDR, backup immutability, and incident-response documentation as conditions of coverage. Our baseline configuration meets the requirements of Beazley, Chubb, AIG, Travelers, and the major specialty markets. Carrier-specific attestations available on request. ## Ready for a privilege-preserving security review? Free passive external assessment.
