Ransomware Activity Detection System (RADS) is DoubleShield countermeasure against hidden ransomware with the objective of encrypting or corrupting all your backup copies without letting you know, because the ransomware authors know that if you still have any clean backup, you will not pay for the ransom.
With RADS, we can detect hidden ransomware much earlier, normally in the initial stage of the attack, so we can isolate the affected device and also start the recovery much earlier and thus minimize the data loss and avoid business-threatening down time.
