I have seen attacks that have been prevented by it, so I would say I have seen clients receive a return on investment. The older units do not work as well – you have to upgrade them – but they seem to be handling things pretty decently.

The product is worth the money.

We've seen pretty good ROI so far.

You need a network firewall, so it's not a question of ROI. You need air. You need electricity. You need the firewall.

I like to think that the TZ series has the best bang for the buck. Full of features and options that you need to control security with out breaking the bank. Perfect solution for smaller businesses.

We have seen a 100% ROI. There are no intrusions. 

I've seen great ROI since implementing it.

We have seen many cases where installing the SonicWall has helped with security threats or just for safe user browsing

It delivers an immediate ROI with a low cost of managing and maintaining multiple security solutions, it increases productivity, and improves security.

I imagine that we have seen a return on our investment, but it is invisible. It is a firewall and we haven't suffered any loss. Had we, then it would have been a lot more than the cost of the device and the license. As far as I'm concerned it pays for itself instantly.

It normally comes within eight months for us.
