The New Frontier of Email Defense

Email remains the #1 threat vector. As organizations migrate to the cloud, the paradigm is shifting from perimeter gateways to integrated AI-native security layers.

📈 The 2025 Threat Vector

90% of sophisticated cyber-attacks start with a single email. While malware is decreasing, social engineering and identity-based attacks are at an all-time high. This visualization demonstrates why modern defenses must look beyond simple file signatures and toward behavioral intent.

Evolution: From MX Gateways to Graph APIs

Traditional Secure Email Gateways (SEG) rely on MX-record changes. Modern ICES solutions integrate directly with cloud platforms (M365/Workspace) for deeper visibility.

The Vendor Selection Matrix

The market is split between "Comprehensive Platforms" and "Best-of-Breed Disruptors." This scatter plot maps vendor technical innovation against market adoption velocity. Note the high agility of API-based players.

Public Sector Compliance Hub

For Public Sector entities (Fed/State/Local), security is not just about capability—it's about compliance authorization. FedRAMP Moderate is the minimum standard for most federal agencies. We have validated the following status for key providers:

Microsoft 365 GCC FedRAMP HIGH
Abnormal Security FedRAMP MODERATE
Proofpoint (POD) FedRAMP MODERATE
Mimecast Gov FedRAMP MODERATE
Barracuda Email Security FedRAMP MODERATE

The Forward-Looking Outlook

🤖

Generative AI Arms Race

Attackers use LLMs to create "perfect" lures without typos. Defensive AI must move from scanning files to understanding semantic context and human relationships.

🛠️

Detection as Code

Platforms like Sublime Security are democratizing detection. SOC teams can now write, share, and automate custom detection rules using MQL (Message Query Language).

🔄

Platform Consolidation

Email data is being ingested into XDR/SIEM platforms for cross-domain correlation. The "Best-of-Suite" vs "Best-of-Breed" debate is shifting toward "Best-of-API".
