KnowBe4, provider of the world’s largest security awareness training and simulated phishing platform, has entered into a definitive agreement to acquire Egress, a leader in adaptive and integrated cloud email security.

Orrick represented Egress.

Terms of the transaction were not disclosed.


As advanced persistent threats continue to evolve, Egress recognizes that people are the biggest risk to organizations’ security and are most vulnerable when using email.

Egress is the only cloud email security platform to continuously assess human risk and dynamically adapt policy controls, preparing customers to defend against advanced phishing attacks and outbound data breaches before they happen. Leveraging contextual machine learning and neural networks, with seamless integration using cloud-native API architecture, Egress provides enhanced email protection, deep visibility into human risk, and instant time to value.

Egress’ Intelligent Email Security suite provides a set of scaled, AI-enabled security tools with adaptive learning capabilities to help prevent, protect and defend organizations against sophisticated email cybersecurity threats.

KnowBe4, the provider of the world’s largest security awareness training and simulated phishing platform, is used by more than 65,000 organizations around the globe. Founded by IT and data security specialist Stu Sjouwerman, KnowBe4 helps organizations address the human element of security by raising awareness about ransomware, CEO fraud and other social engineering tactics through a new-school approach to awareness training on security.


The addition of Egress’ cloud email security solution to KnowBe4’s comprehensive product suite will create the largest, advanced AI-driven cybersecurity platform for managing human risk.

Through the acquisition, KnowBe4 plans to deliver a single platform that aggregates threat intelligence dynamically, offering AI-based email security and training that is automatically tailored relative to risk. 

“KnowBe4 and Egress have a shared vision of delivering tailored and relevant security to each employee,” said Tony Pepper, CEO, Egress. “One of the biggest challenges organizations face is accurately identifying who the next source of compromise is – and why. By combining intelligence and analytics from integrated applications, companies can gain valuable insights across their entire cyber ecosystem, allowing them to focus on the risks that matter most.”
