From Legacy to ICES: Separating Marketing Hype from Proven Email Defense

The email threat landscape is evolving at an unprecedented pace. Cybercriminals, fueled by advancements in AI and a thriving crime-as-a-service ecosystem, are deploying increasingly sophisticated attacks designed to circumvent traditional perimeter defenses and exploit technology and human errors.

This shift has led a significant majority of cybersecurity leaders—nearly 87%—to either consider replacing their secure email gateway (SEG) or to have already done so.

Here’s the issue: SEGs were engineered for a previous generation of threats. Their architecture, which inspects mail before it reaches the cloud tenant, lacks the deep contextual insight needed to identify today’s most damaging attacks.

The time has come to give traditional SEGs a critical look. How best to determine if they
still meet your needs? Read on to explore a strategic framework for assessing your current email security architecture, identifying the signs that your SEG is becoming obsolete, and planning a successful transition to a more effective, integrated defence model.
