Sophos XG Physical or Virtual for a business with 300 plus users

Donnie Johnson

We need to purchase a new firewall for our business. We currently use Sophos XG virtually in a branch office but I'm concerned about performance in a virtualized environment. This firewall would run all the IPS and Malware protection plus serve up to 150 VPN connections. Can anyone speak on this?

    I'd generally advise to go virtual . Yes you pay a performance overhead penalty but on the other hand you can buy much more powerful hardware than what is inside an XG box for the same amount of money . I generally say to customers anything over a XG 135 to just go virtual in general . It's also very easy to upgrade to higher capacity if you purchased a machine with some breathing room ( aka cpu cores / memory )

    One thing you have to take into consideration is in a lot of cases clock speed is still pretty much the deciding speed factor as many underlying tasks as lot of the stuff is still very much single core bound I've found.
