Secure File Sharing and Email Encryption for Law Firms

Virtru's data-centric security platform encrypts privileged communications, client files, and litigation documents at the object level — so protection travels with the data wherever it goes. Trusted by more than 6,000 organizations across regulated industries, Virtru helps law firms support ABA standard of care, state bar rules, CJIS, HIPAA, GLBA, and TILA-RESPA without disrupting the workflows attorneys already use.

Legal Cybersecurity Solutions for Law Firms and Legal Teams

From solo practitioners to AmLaw 100 firms, legal teams need security that works the way they do — across email, file sharing, and outside counsel collaboration. Virtru delivers data-layer protection that integrates with Microsoft 365 and Google Workspace, with no client software required for recipients.

Virtru Email Encryption encrypts messages and attachments client-side, before they leave the sender's device. Messages remain protected in transit, at rest, and in recipients' inboxes — even when forwarded. Attorneys activate encryption with a single toggle inside Outlook or Gmail. No certificate management, no S/MIME setup, no recipient enrollment required. This is what email encryption for lawyers should look like: Invisible to the user, and persistently tied to the data everywhere it travels.

Legal Cybersecurity Compliance for Every Practice Area

Law firms handle data subject to overlapping regulatory frameworks. Virtru supports legal cybersecurity compliance across the full spectrum of practice areas — without forcing your firm to deploy a different tool for each requirement.

Attorney-Client Privilege and ABA Standard of Care

Encryption is no longer optional for privileged communications. Virtru protects email content and attachments with E2E object-level encryption, ensuring that privileged information remains confidential even if a recipient's inbox is compromised. Granular policy controls help firms demonstrate the reasonable safeguards aligned with ABA Formal Opinion 477R and corresponding state bar guidance. For matters that demand the strongest assurances, Virtru Private Keystore lets your firm hold the encryption keys itself — preserving privilege even against subpoena risk to cloud providers.

CJIS Compliance for State and Local Legal Teams

District attorneys, public defenders, and state legal teams handling criminal justice information face strict requirements under the FBI's CJIS Security Policy. Virtru aligns with the CJIS Security Policy by encrypting CJI in transit and at rest, supporting advanced authentication, and providing the auditing controls needed for inbound and outbound communication. Pair Virtru email, file sharing, and collaboration solutions with Virtru Private Keystore to maintain full encryption key sovereignty for the most sensitive caseloads.

HIPAA Compliance for Healthcare-Adjacent Practices

Medical malpractice, personal injury, and healthcare M&A practices regularly handle protected health information (PHI). Virtru offers a standard Business Associate Agreement (BAA) and provides the technical safeguards — encryption, access controls, and audit logging — that support your firm's HIPAA compliance program. Whether you're sending records to expert witnesses, exchanging documents with co-counsel, or managing client intake, Virtru ensures PHI remains encrypted across every step of the matter.

TILA-RESPA, GLBA, and Real Estate Practice Compliance

Firms handling residential real estate closings, mortgage transactions, and consumer finance must protect non-public personal information under the FTC Safeguards Rule (GLBA) and TILA-RESPA. Virtru's automated policy enforcement detects sensitive data patterns — Social Security numbers, account numbers, settlement details — and applies encryption automatically through the Virtru Data Protection Gateway. The result: nothing leaves your firm unprotected, even when an attorney or paralegal forgets to apply encryption manually.

Virtru for Mergers, Acquisitions, and Complex Litigation

M&A transactions and high-stakes litigation create concentrated exposure: deal terms, board materials, deposition transcripts, and expert reports all flow between firms, opposing counsel, financial advisors, and regulators. Traditional secure data rooms force everyone onto a single platform; Virtru lets you protect documents wherever they need to go.

With Virtru, deal teams and litigation teams can:

  • Set time-bound access on draft agreements that expire automatically when a deal closes or terminates

  • Revoke counterparty access instantly if negotiations break down or an engagement ends

  • Track which outside counsel, banker, or board member has reviewed each version

  • Maintain encryption key sovereignty so neither Microsoft, Google, nor Virtru can decrypt deal data
Virtru offers first-mile to last-mile data protection, from the moment a draft is created in Word to the final close-out, encryption travels with the file across organizational boundaries, classification levels, and platforms.

Why Law Firms Choose Virtru

Easy to Use — No Software for Outside Counsel

Attorneys send encrypted email and shared files from inside Outlook and Gmail with no behavior change. External recipients — including opposing counsel, expert witnesses, and clients — read, reply, and download files through a browser. No plugins, no new logins or passwords, no IT tickets. Adoption is as simple as a blue toggle button in the email interface.

Integration, Not Replacement

Virtru integrates natively with Microsoft 365, Google Workspace, and the document management systems law firms already rely on, including Microsoft OneDrive and SharePoint. Your existing identity provider — Okta, Microsoft Entra ID, or Google Workspace — drives access. Your existing classification labels, including Microsoft Purview Information Protection, can feed Virtru's policy engine. We meet your firm where it is, rather than asking attorneys to learn another tool.

Avoid S/MIME and SFTP Headaches

S/MIME forces certificate distribution to every external party. SFTP requires client software and admin overhead. Both fail when attorneys need to communicate quickly with parties outside their certificate or VPN trust boundary. Virtru replaces both with a data-centric model that protects the document itself, and the document defends itself wherever it travels.

Maintain Encryption Key Sovereignty

For matters involving CJIS data, ITAR-controlled information, or international counsel, Virtru Private Keystore lets your firm host its own encryption keys. Even Virtru cannot access your protected content. This level of control is essential for high-sensitivity practice areas and supports regulatory requirements that prohibit third-party access to encryption keys.
