The Essential Guide to Retiring the SEG

Explore why organizations are retiring third-party secure email gateways as layered email security becomes essential in modern cloud environments.

Key Insights

Modern attacks use legitimate domains, trusted relationships, and AI-crafted content to bypass static, rule-based SEG inspection.

Third-party SEGs create blind spots, duplicate native cloud protections, and add operational drag in cloud environments.

SEG costs accumulate across both licensing fees and SOC workflow overhead.

Native cloud protection paired with behavioral detection offers stronger coverage than perimeter-based filtering.

The SEG was designed for a different era and is misaligned with threats that exploit human behavior rather than known signatures.

Organizations are rethinking the role of the third-party secure email gateway (SEG).

Built to block known threats at the perimeter, third-party SEGs were designed for a different era. Today’s attacks rely on legitimate domains, trusted relationships, and AI-crafted content that exploits human behavior—tactics that bypass static, rule-based inspection.

Based on The Essential Guide to Retiring the SEG, the infographic outlines why third-party gateways create blind spots, duplicate native cloud protections, and add unnecessary operational drag in modern environments.
