How often are security rules updated?
To protect your computers from the latest threats, Trend Micro regularly distributes updates to the security rules used by Deep Security.
Before April 11, 2017, the security rules for intrusion prevention, integrity monitoring, and log inspection were updated on the second and fourth Tuesdays of each month (plus non-scheduled updates for critical threats). To respond to threats and vulnerabilities even faster, beginning April 11, updates will happen on a weekly basis.
