Five GovCon Executives Specializing in Cyber Solutions

Civilian and military organizations now depend on the cyber domain for many of their functions. A string of high-profile cyberattacks over the past years demonstrated how disruptive cyberattacks can be when aimed at federal agencies and critical infrastructure sectors.

Government officials and industry experts have been calling for stronger cybersecurity in sectors such as oil and gas, health care and satellite communications.

The Department of Defense has also adopted a “defend forward” strategy to proactively root out threats in cyberspace, which the military now considers as an operational domain alongside air, land and sea.

The Potomac Officers Club—a division of Executive Mosaic—features five cyber solutions executives in the government contracting sector.
