For small form factor appliances (e.g., 4-Core / 8-GB models) running the Premium SPACK with Next-Generation Firewall (NGFW) and Unified Threat Management (UTM) features enabled—such as Antivirus (AV), Intrusion Prevention System (IPS), and URL Filtering (URLF)—we highly recommend the following configuration to optimize memory:

  • Enable urlf cloud Lookup

  • Disable the URL Category Database.

FAQ's:
