Microsoft Defender removes 70 per cent of malicious emails post-delivery, according to Microsoft’s latest benchmarking data.  

A performance evaluation report shows layering integrated cloud email security (ICES) solutions with Microsoft Defender improves filtering by an average of 13 per cent. The data underscores post-delivery detection as a critical backstop for organisations to put in place to defend against cyberthreats bypassing initial filtering.   

“When Defender operates alongside ICES partners, organisations benefit from incremental detection gains across promotional, spam and malicious messages”, said Jeff Pinkston, vice president and general manager of Defender for Office 365, in a recent blog post.  

The ICES vendor ecosystem for Defender gives customers a number of trusted non-Microsoft email security solutions to work with, such as those developed by Cisco, Darktrace, KnowBe4 and Vipre Security Group. They provide tools for a variety of security challenges including email entity pages, advanced hunting and reporting. 

Adding Microsoft Defender for Office 365 to the ICES vendor ecosystem offers security teams the clarity of a single operational plane with enhanced protection through layering multi-vendor email security technologies.   

“Email security is strongest when it combines native platform intelligence with specialist partner capabilities,” said Pinkston.
