DomainTools

DomainTools is the global leader for Internet intelligence that enables security practitioners to proactively defend their organization. Put simply, it is about assessing, monitoring and responding to security threats on your behalf.

It makes the most sense for companies without a full security team. Related areas on their profile: Cyber Security, Security and Web Hosting. 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.

DomainTools is based in Seattle, Washington and around since 2004. More on domaintools.com.

Things worth asking about: response times, what is included in monitoring, and reporting. Get the renewal terms in writing before the first invoice.

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