Microsoft’s Defender ATP has been a big success. The EDR-based solution for endpoints is taking the market by storm and organizations are often using the renewal dates of their current solution to move to Microsoft’s E5 licensing package to enjoy the benefits of behavioral endpoint analysis and protection.

Recently, Microsoft announced the general availability of Microsoft Threat Protection (MTP). The new over-arching solution combines signals from Microsoft Defender ATP (endpoints), Office 365 ATP (email), Azure ATP (identity) and Microsoft Cloud App Security (apps) into one central portal.
