A few weeks ago, BitDam ATP detected an outstanding attack
Real-time data on miss rates and Time to Detect by O365 ATP and G Suite Enterprise, exposed through BitDam Malware Feed.
We constantly retrieve very fresh samples of malicious files from various feeds and sources, qualifying them as Unknown Threats, and then sending them to mailboxes protected by Office365 ATP, G-Suite Enterprise or Symantec. We measure miss rate at first encounter and Time To Detect (TTD) for these Unknown Threats.
Our findings so far show a miss rate of 20-40% and an average Time To Detect of 10-53 hours by different security vendors.
