Our experience ranges from supporting Department of Defense programs, mission critical divisions, and government enterprise networks. Our vision's primary step is keeping opponents from launching an attack on your business perimeter. In cyber-warfare, against terrorists and nation states, this can involve deterring attacks by the threat or initiation of offensive cyber strikes or even physical attacks.

In cyber-warfare, against terrorists and nation states, this can involve deterring attacks by the threat or initiation of offensive cyber strikes or even physical attacks. Broader elements of defense common in commercial cyber-security include improved software design, such as designing systems to “fail secure” rather than “fail insecure”, use of firewalls, proper access control and authentication, and encryption. Increasingly, this entails protecting not just “data at rest,” such as information in databases, but also “data in transit” between devices or networks. The latter is increasingly important due to the proliferation of mobile computing and devices, wireless connections, and cloud computing.
