Compter Network Scurity Assessments

The road to a secure computer network starts with an Internet Security Assessment. Our network security experts try to hack your network in an ethical manner using the same tools that hackers use. You get an "executive-style" report with detailed problem descriptions plus recommended solutions.

Computer technical support services

Since security requires a firm foundation, we offer 24x7 IT support services in many areas of computer networking including MS Windows Server, VMware, Hyper-V, Linux, firewalls, switching & routing systems and data backup.  Recovery of crashed / compromised physical servers is a specialty. 

Managed Services

Once your network is stabilized and secured, you can take advantage of our CompleteCARE Managed Services offerings which provide consistent and proactive service and support delivery for a fixed monthly fee. Take the guesswork out of your IT support expenditures with CompleteCARE from Dominant Systems.
