This page provides security advice, including steps that can be applied after installation of Whonix ™ for better security.
On Whonix-Gateway ™ and Whonix-Workstation ™
Increase Virtual Machine RAM
- Whonix-Workstation ™: No changes are necessary for most users.
- Whonix-Gateway ™: If enough host RAM is available, ideally the virtual RAM setting of Whonix-Gateway ™ should be increased to
2048MB RAM.  If it is infeasible to increase the virtual RAM setting, Whonix-Gateway ™ will still function properly.
