What Law Firms Should Use Now That Tessian and Egress Are Inside Enterprise Suites
Tessian was acquired by Proofpoint. Egress was acquired by KnowBe4. Both products did something important for law firms. Both are now being folded into enterprise platforms built for organizations ten times your size. Here is what comes next.
What Tessian and Egress did well
Both products earned their market position. They solved a real problem: law firms were sending documents to the wrong people, and the existing tools (training and Outlook rules) were inadequate.
- Outbound email misdirection protection (wrong recipient detection)
- Employee coaching and security awareness nudges
- DLP policy enforcement on email sends
- Retroactive message recall for misdirected emails
What the acquisitions mean for law firms
Tessian
Acquired by Proofpoint (2023)Tessian's standalone product was absorbed into Proofpoint's enterprise security suite. Small and mid-size law firms that adopted Tessian as a standalone solution are now evaluating enterprise pricing and complexity they didn't sign up for.
Egress
Acquired by KnowBe4 (2024)Egress's outbound email protection features are being integrated into KnowBe4's security training platform. Firms that used Egress for document-level protection are finding the integrated product is moving toward awareness training, not document privacy.
The next generation: full cloud coverage, not just email
Tessian and Egress focused on outbound email. They did email well. But email is less than half of how law firms share documents today. SharePoint shared links, OneDrive folder access, Teams file transfers, and direct SharePoint exports all move documents outside your firm without going through email at all.
Dataguard covers the full surface. Every document that leaves your firm, regardless of the channel, is reviewed and protected before it reaches the recipient. That includes the email case, which Tessian and Egress solved, and every other sharing mechanism in your cloud that they didn't.
If you relied on Tessian or Egress for outbound email protection, Dataguard replaces what they did and extends it across your entire cloud environment.
Three steps. Zero behavior change from your team.
DataGuard runs automatically in the background. Your paralegals don't learn a new tool. They just stop accidentally sending things they shouldn't.
DataGuard lives inside the tools you already use
No new tools for your team to learn. DataGuard installs directly into Outlook, Gmail, OneDrive, Google Drive, SharePoint, and Clio, the tools your team already uses every day.
Every outbound document is scanned automatically
When a document is about to leave the firm (via email, a shared link, or a file attachment) DataGuard reads it against your privacy policies before it reaches anyone outside.
Sensitive content is removed. The share goes through clean.
SSNs, diagnosis codes, government IDs, and other restricted information are stripped from the document. The recipient gets a clean file. Your team gets a summary of what was removed. The audit log records the event.
