We believe KnowBe4’s recognition as a Leader in the Gartner Magic Quadrant is reflective of the following strengths regarding KnowBe4 Cloud Email Security:    

  • Advanced AI-enabled detection to mitigate the full spectrum of inbound phishing attacks and outbound data loss and exfiltration attempts
  • KnowBe4’s Agentic Detection Engine that leverages sophisticated natural language processing (NLP) and natural language understanding (NLU) models to protect inboxes from advanced phishing, impersonation and account takeover attacks 
  • Integration in the KnowBe4 HRM+ platform that uses deep per-user behavioral analytics and threat intelligence to deliver personalized security at the point of risk
  • Continuous behavioral-based training delivered through real-time nudges

A rise in advanced technology to address sophisticated phishing attacks and behavior-led outbound data breaches has driven significant innovation in email security. According to the KnowBe4 2025 Phishing Threat Trends Report Vol. Six, there was a 15.2% increase in phishing email volume between March 1st - September 30th, 2025, compared to the previous six months.

“We are honored to be recognized as a Leader in the 2025 Gartner Magic Quadrant for Email Security Platforms,” said Bryan Palma, CEO, KnowBe4. “Email communication remains the primary attack vector for organizations globally. KnowBe4 plays an instrumental role in providing adaptive AI-enabled technology to build a stronger security culture for customers. In our opinion, this positioning validates our strategic vision and relentless focus on human and agent risk management that goes beyond detecting threats to preventing them before they reach employees’ inboxes.”

This news follows several recent announcements which we believe exemplifies the strength of KnowBe4 Cloud Email Security, including the integration of Microsoft Defender O365 and recognition as a Gartner Peer Insights Customer’s Choice for email security platforms.
