A fresh round of recognition just landed for Check Point, and it tells an interesting story about where email security is headed. The company has been named a Leader in the 2025 Gartner Magic Quadrant for Email Security—an area that still feels surprisingly foundational even as enterprises pour money into cloud security, zero trust, and AI-driven threat detection. What’s striking in the backdrop of this announcement is how email remains the primary front door for attackers. Check Point’s own 2025 Security Report pegs the number at 68% of attacks starting with email, and a frankly alarming 61% of malicious files being sent as HTML attachments. It’s a reminder that attackers aren’t bothering with sophistication when old tricks still work.
Harmony Email & Collaboration is the centerpiece here, positioned as a full-stack, AI-powered shield built to sit in front of Microsoft 365 and Google Workspace. The one-click API deployment has become one of Check Point’s signature talking points, mostly because it skips the painful MX record rerouting that many legacy secure email gateways still rely on. Once connected, the system scans mail pre-delivery and extends protection to Teams, Slack, OneDrive, and SharePoint—an increasingly necessary expansion as attacks bleed out of inboxes and into chat, document-sharing, and internal messaging tools.
One detail that jumps out is the built-in autonomous phishing simulation. Check Point is betting on a future where phishing tests don’t need separate vendors, scheduling, templates, or internal politics; instead, AI-triggered contextual simulations just weave themselves into day-to-day flows. For resource-tight CISOs, this is exactly the kind of operational simplification that accelerates adoption.
Check Point also gives itself credit for being the only pure-play email security leader that simultaneously covers endpoints, AI-driven protections, SSE, external exposure management, and DLP—all part of the consolidated Infinity Platform vision. The customer quote from Telefónica reflects that shift: people want security that works in the background, without adding friction or complexity. And with Check Point also ranked a Leader in the Gartner Magic Quadrant for Hybrid Mesh Firewall, the company is clearly leaning hard into its “integrated workspace protection” narrative.
What this recognition ultimately signals is that email security vendors can’t just block phishing anymore. The battleground has widened to collaboration platforms, real-time detection, behavior-driven AI models, and fully integrated security operations. Check Point has positioned Harmony Email as a system that plugs directly into that future—one that assumes attackers will keep probing inboxes long after everything else moves to AI-driven automation.
