VoIP Defender

VoIP Defender distributes and offers managed services based on AtomOS. The job it does: assessing, monitoring and responding to security threats on your behalf.

Who is it for? Mostly companies without a full security team. They also list Network Security, Software Engineering and VoIP, so expect those to show up in the feature set. They are a very small team, 1 to 10 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

VoIP Defender is based in Lake Zurich, Illinois and around since 2014. More on voipdefender.com.

Things worth asking about: response times, what is included in monitoring, and reporting. Ask for a trial on your own data, not a canned demo.

If you have worked with VoIP Defender, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
