Version 6.3.5.1128

Release date:

  • Slow ring: 2026.06.30

Important

This version also includes, on slow ring, the improvements and fixes delivered with Security Server Multi-Platform version 6.3.5.1126, released on fast ring.

New features and improvements

Product

  • This release enhances SSH security for supported Security Servers by disabling direct root SSH access and introducing a dedicated bdadmin account for administrative tasks.

    The bdadmin account has superuser privileges and uses the existing root password hash, helping maintain administrative access while reducing the risks associated with direct root logins over SSH.

    This change also updates password management behavior. By default, passwords for the bdadmin account expire after 90 days. In addition, password changes initiated from GravityZone now apply to the bdadmin account instead of the root account.

  • New instances have been added for the Communication Server:

    • For cloudrbx.ovh.gravityzone.bitdefender.com: GZ RBX Cloud Instance

    • For cloudham.s11.gravityzone.bitdefender.com: GZ SysEleven Cloud Instance

    • For cloudher.dts.gravityzone.bitdefender.com: GZ DTS IT AG Cloud Instance

  • Product maintenance and quality improvements.
