What Is Advanced Threat Protection?

Email remains the #1 attack vector for cybercriminals.  

From phishing and malware to impersonation and data leaks, the threats are constant and increasingly sophisticated.  

That’s why businesses need more than just the basics.  

They need layered, intelligent protection that evolves with the threat landscape. 

At Systemagic, we provide our clients with a powerful email filtering solution that adds a critical layer of defence on top of Microsoft 365.  

And we’re not alone in this approach – Microsoft itself encourages it. 

What Is Email Filtering? 

Email filtering is the process of automatically scanning and managing incoming and outgoing email messages to detect and block unwanted or harmful content.  

This includes spam, phishing attempts, malware, and other threats. Filters use a combination of rule-based logic, threat intelligence, and machine learning to assess the legitimacy and safety of each message.  

The goal is simple: ensure that only safe, relevant emails reach your inbox while keeping malicious or unnecessary ones out. 

Microsoft’s Position: Third-Party Filtering Enhances Security 

In a recent blog post, Microsoft shared that combining third-party Integrated Cloud Email Security (ICES) solutions with Microsoft Defender for Office 365 delivers the greatest impact in detecting threats – especially promotional or bulk email.  

Their analysis shows an average improvement of 20% in detection rates when third-party tools are added to the mix.  

This is a clear signal: Microsoft 365 is a strong foundation, but for optimal protection, businesses should layer in additional defences.
