On DEC-01-2020 Barracuda NextGen X-Firewall (BFW, NGX) has reached its End-of-Life and End-of-Support.
With an active Energize Updates subscription the product will still work, but there will be no longer any bug fixes, any security fixes, and no firmware releases or hotfixes available.
Barracuda customer service and support team will be happy to help you to migrate to the higher featured Barracuda CloudGen Firewall product series, which is available as hardware, virtual or cloud appliance.
