TESTIMONIALS
From the users
Manuel Alexander HerzogOPNsense User
"Sophos UTM is good but to sofisticated for my needs. So I tried OPNsense and now EVERYTHING is as I want to have it. It is simple and with a great GUI."
Boris HoppeCEO CompuNet Systems GmbH
"OPNsense provides more features, more reliability and more performance than any other commercial firewall product we had in use ever before. Being open source, we have full access regarding update plans and so on."
