Whether configuring Vsys will make firewall more secure or not

L2 Linker

I would like to know advantage and disadvantage of implementing Vsys. 

in an environment , we are able to configure our firewalls with vsys or without vsys. 

Would also like to know whether configuring vsys will make firewall more secure or not ?

Hello @perumalj 


Good evening, it all depends on the use.


Example if you have a firewall or a HA of a pair of PA 52XX series, you have the possibility to use virtual systems. That allows you virtual system, to be able to segment a Firewall in several, example:

Thinking about a company, an enterprise, or a Holding company and you want each of the companies to have its own virtual firewall inside a physical hardware, is where in this use case ( there are more ) can make sense:



Company 1: Will have the VSYS1 and will occupy the first 4 interfaces of the Dataplante.
Company 2: Will have VSYS2 and occupy 2 interfaces (smaller network).
Company 3: Will have VSYS3 and will occupy other 4 interfaces.


And so, you can segment the administration, changes, policies, among others.


Here are some docs with details and use cases:
