Staying ahead of modern-day attacks Part 2: Defense-at-Scale approach with Office 365 ATP
Pragya Pandey Thanks for the overview above. Re this line: "Of the 400 billion emails analyzed by our threat protection engines monthly EOP and Office 365 ATP flag around 600 million email messages as malicious. That means only 0.0015% of all the emails analyzed are bad." Can you please clarify whether you are saying:
- Microsoft analyses 400 billion emails each month using EOP and ATP, and of these, only 600 million are malicious (according to EOP and ATP); OR
- Microsoft analyses 400 billion emails each month for threats, and after doing this analysis, EOP and ATP then separately flag 600 million as malicious.
Secondly, for the threats that EOP and ATP do not capture, do you recursively re-calculate the threat error catch rate? e.g., for the phishing emails that are delivered to my Office 365 tenants, are they included in the 0.0015% rate noted above?
