Xylon

Xylon offers software development, IT security, data recovery, and network infrastructure design services. The job it does: assessing, monitoring and responding to security threats on your behalf.

The natural audience is companies without a full security team. Related areas on their profile: Hardware and Security. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Xylon is based in Minneapolis, Minnesota. Their site is xylon.tv.

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.
