Advanced Email Security for Financial Institutions

Stop advanced phishing, impersonation, and fraud that bypass traditional email security. Protect your organization with AI-driven detection that understands intent, not just content.

 

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

Business impact for banks

  • Prevent fraudulent payments before approval 
  • Reduce phishing exposure to employees
