Egress A Knowbe4 Company
What it is
What It Does
Egress is a cloud email-security company. Its products cover adaptive inbound threat detection (phishing, account takeover) and outbound data-loss prevention — flagging emails sent to the wrong recipient or carrying sensitive attachments. It is not a legal-specific tool, but the email-misdirection and DLP features are used by law firms and other professional-services organisations handling confidential client material. The platform integrates deeply with Microsoft 365.
What We Found
KnowBe4 — the security-awareness-training vendor — acquired Egress in 2024 (announced April, completed July 2024), so Egress now operates as a KnowBe4 company, which the page name reflects. Egress is London-based and reportedly raised around $48M across funding rounds before the acquisition.
What We Haven’t Verified
- Post-acquisition headcount and current standalone metrics.
- Egress is general email security rather than legal tech; its presence in legal directories reflects law-firm usage, not a legal-specific product.
