Email security is no longer about blocking malicious messages, it’s about understanding behavior, intent, and risk in real time, specific to your organization. As attackers use AI to enhance phishing success and abuse identities, CISOs should be rethinking what they need from their email security stack.

CISO's Guide to Email Security: Protection & Threats
Today’s organizations rely on a connected ecosystem of email, collaboration platforms, and SaaS tools to keep employees, customers, partners, and suppliers connected.
At the same time, the nature of the threats targeting communication platforms is evolving. While attackers have always sought to exploit trust and normal business behavior, advances in technology have made it easier and more cost- effective to carry out sophisticated attacks at scale. AI has accelerated this shift. Phishing messages are more polished, targeted, and easier to produce at scale – with AI-assisted phishing text doubling year-over-year.
For CISOs, this means email security is no longer just a filtering problem. It’s an identity, trust, data protection, and business-risk problem, one that requires defenses capable of adapting as quickly as attackers do.
This guide enables CISOs to assess the requirements of a modern email security solution, what to prioritize, and how to evaluate competing solutions against key capabilities like behavioral approach, native email integrations, and operational friction.
