What license is required when enabling Autonomous Ransomware Protection(ARP)

Last Updated:

Applies to

  • ONTAP 9.10.1
  • ONTAP 9.11.1 and later
  • Autonomous Ransomware Protection(ARP)


Beginning with ONTAP 9.10.1, the Autonomous Ransomware Protection (ARP) feature uses workload analysis in NAS (NFS and SMB) environments to proactively detect and warn about abnormal activity that might indicate a ransomware attack.

The ARP feature is enabled with the following licenses:

ONTAP releases License

ONTAP 9.11.1 and later


ONTAP 9.10.1

MT_EK_MGMT (Multi-Tenant Key Management)

  • If you are upgrading to ONTAP 9.11.1 or later and ARP is already configured on your system, you do not need to purchase the new Anti-ransomware license. For new ARP configurations, a new license is required.

  • If you are reverting from ONTAP 9.11.1 or later to ONTAP 9.10.1, and you have enabled ARP with the Anti-ransomware license, you will see a warning message and might need to reconfigure ARP. Learn about reverting ARP.
