Email is now a primary fraud channel. 60% of incidents start with phishing, 16–30% of breaches begin there, and ~75% involve human interaction. At the same time, AI-driven social engineering is making attacks more targeted, convincing, and harder to detect.

Why traditional SEG approaches fall short

Secure Email Gateways (SEGs) and native tools like Microsoft 365 are designed for known, high-volume threats: 

• Spam, known malware, mass phishing 
• Signature, reputation, and rule-based detection 

But modern attacks are different: 

• Business Email Compromise (no links, no payload) 
• AI-generated, context-aware phishing 
• Compromised internal or supplier accounts 
• Attacks that evolve after delivery 

Why Advanced Email Security is different

Advanced Email Security focuses on intent, behavior, and context – not just content. 

With solutions like Open Systems: 

• Behavioral AI detects abnormal requests (e.g. payment changes) 
• Relationship analysis identifies impersonation and fraud patterns 
• Internal monitoring detects compromised accounts 

What you get

Business impact for banks

• Prevent fraudulent payments before approval 
• Reduce phishing exposure to employees 
• Lower breach and fraud costs (>$1M per incident on average) 
• Strengthen regulatory defensibility and audit posture

Proven impact in real environments

Organizations using Advanced Email Security are seeing measurable results – as demonstrated in environments like Marquardt Group: 

• +25% more malicious emails blocked  
• <0.1% false positives (near-zero business disruption)  
• Significant reduction in phishing emails reaching users  
• Lower ticket volumes for IT and security teams  
• Reduced financial and reputational risk

What this means:
Stronger protection, fewer incidents, and less operational effort – all at the same time.
