Current Challenges
Despite deploying a spam gateway, the enterprise continues to face infiltration by phishing scams, malicious code emails, and Business Email Compromise (BEC) attacks—posing serious risks to corporate security and core business data. The globally distributed office structure further complicates centralized email protection, making unified threat defense increasingly difficult to maintain.
Requirements
-
Accurately identify virus emails, social engineering attempts, and targeted spear-phishing attacks.
-
Eliminate spam and gray-area emails to minimize operational disruptions and improve email efficiency。
Deployment method
PhishShield was deployed in BCC forwarding mode, enabling covert secondary inspection of all email traffic without modifying the existing routing architecture. This approach ensures robust threat detection while maintaining operational transparency and business continuity.
Implementation Results
Initial Phase (June): Nearly 600 malicious emails were intercepted in a single month,revealing a high-risk threat environment.
Optimization Phase (July–August, November): Interception volumes steadily declined as the protection mechanisms adapted and matured.
