Five GovCon Executives in Cyber Defense

Cybersecurity is becoming more important as organizations continue to rely on technology for various tasks. Government agencies, in particular, use IT and emerging technologies for workforce training, clerical tasks and other business functions.

As government agencies continue to rely on technology, they become more prone to cyber risks that could lead to compromised systems, national security breaches and failure of services. To combat these threats, cybersecurity companies offer products, services and subject matter experts to ensure that networks and systems are protected.

The Potomac Officers Club – a division of Executive Mosaic – presents five government contracting executives in cyber defense.
