XG Firewall v18 MR-3

Hi XG Community!

We've released a new build of XG Firewall v18 MR-3.

Enhancements in v18 MR-3

Security enhancements:

  • Several security and hardening enhancements - including SSMK (secure storage master key) for the encryption of sensitive data. Refer KB-000040174 for more details.
  • Granular option to enable/ disable captcha authentication from CLI

VPN Remote Access enhancements:

  • Increase in SSL VPN connection capacity across entire firewall line up; 6x increase for 2U HW. KB-000039345 is being updated with enhanced capacity.
  • Group support for Sophos Connect VPN client

Cloud - AWS/ Azure/ Nutanix enhancements:

  • Support for newer AWS instances - C5/ M5 and T3 (#)
  • Support for CloudFormation Templates removing the need to run installation wizard in some cases (#)
  • Virtual WAN Zone on custom gateway for post deployment single arm usage
    • On single arm – single interface in AWS or Azure – admin can create multiple custom gateway and attached different zones to those gateways. This allows admin to create access and security rules for traffic going in to those zones.
  • XG Firewall is now Nutanix AHV and Nutanix Flow Ready. XG Firewall has been validated to provide two modes of operation within Nutanix AHV infrastructure.
  • Optimize cloud costs and improve security across multi-cloud environments with Cloud Optix. Automatic identification and risk-profiling of security and compliance risks across AWS, Azure and Google Cloud enables teams to fix security gaps and insecure deployments before they are compromised.

(# available after a few days of release on community, once v18 MR-3 is available in the AWS marketplace)

Central management enhancements:

  • XG running in an HA configuration (either A-A or A-P) can now be managed by Sophos Central. Each firewall must be separately joined to the same Sophos Central account, and if grouped, both HA devices must be added to the same group.
  • Audit trail went live under the task queue

Central Firewall Reporting enhancements:

  • Earlier this month, we have released Save, schedule, export & download reports. Refer community post here.

Issues Resolved:

  • 34 field reported issues including RED & HA cluster issues (list below) 

Note: Upgrading from v17.5 MR13/ MR14/ MR14-1 to v18 MR-3 is now supported.
