Why Email Security Is Failing & How to Close the Gap in the Age of AI-Powered Phishing
An inside look at why traditional email defenses fail against AI-powered phishing, featuring real-world data and strategies to close the security gap.
AI has rewritten the phishing playbook. Today’s attackers don’t rely on obvious malware – they exploit trust. Business email compromise (BEC), vendor email compromise (VEC) and account takeover (ATO) attacks are personalized, context-aware and engineered to blend into everyday workflows. And they’re bypassing traditional defenses at scale.
Security email gateways (SEGs) were built for bulk spam and signature-based threats. Many legacy cloud email security tools still depend on static detection and post-delivery remediation. That’s not enough in an AI-driven threat landscape.
Real-world data from KnowBe4 PhishER Plus shows millions of confirmed phishing emails bypass leading email security platforms every month—creating unnecessary risk and operational drag for security teams.
In this white paper, you’ll learn:
- Why SEGs and legacy cloud tools are missing modern, payload-less attacks
- The data behind millions of confirmed threats that reached user inboxes
- The architectural gaps in perimeter-based and disconnected security models
- How to combine Cloud Email Security with AI-driven, human-vetted incident response
- What a closed-loop, measurable email defense strategy looks like in practice
It’s time to take a good, hard look at SEGs.
