Email security report: AI, phishing and the new era of defense

March 17, 2026

Cybercrime has become a structural feature of the digital economy.

Phishing continues to be the most prevalent and impactful attack vector. Early 2025 telemetry from security research groups shows a marked rise in AI-enabled campaigns and infrastructure-based impersonation, indicating that the threat landscape is still in flux. But the story is not just about growth. It’s about transformation.

Generative AI has reshaped phishing from a highvolume nuisance into a precision instrument.

Messages are polished, contextual and increasingly delivered through trusted infrastructure. Traditional detection signals — poor grammar, suspicious domains, obvious malicious links — are now unreliable. In their place: intent-driven manipulation embedded in legitimate workflows.

At the same time, infrastructure risk is concentrating. Major cloud and SaaS platforms now underpin global commerce and communication. The compromise of a single ecosystem can have cascading effects far beyond any individual organization.
