O365 Advanced Threat Protection
O365 ATP makes up the third side of the protection triangle that started by detecting an on-premises attack with ATA, it then covered an attack on the device with Windows Defender ATP and now we are stopping an attack vector through email with a very similar technology.
O365 ATP has a detonation chamber for attachments and can rewrite unsafe links preventing both attacks reaching the end user. While writing this book a ransomware attack called “WannaCry” crippled business worldwide, and it spread through email, and this email attack was stopped for ATP customers!
