We Are Trusted | We Are Proven | We Are Security

TechGuard Security is an ISO 9001:2008-registered, certified SDB, DBE and Woman-Owned Business Enterprise.

TechGuard Security was founded to address national cyber defense initiatives and US critical infrastructure security.

In early 2000, entrepreneur Suzanne Magee recognized a growing need for security and privacy of computer communications with the federal government going paperless and enterprises racing to have a presence on the ubiquitous Internet. Many organizations embraced the Internet with no thought of the vulnerabilities created by unprotected electronic access. With Andrea Johnson, a former computer engineer for the Boeing Company, they founded TechGuard in a small basement office in direct response to Presidential Decision Directive 63 to secure the US Critical Infrastructure. Their mission was to create proactive countermeasures to malicious network attacks through deployment of industry-leading services; and provide cutting-edge research and development of proactive security technology products. As opposed to security remaining a game of catch-up, our approach would help clients stay one step ahead of the hackers and the growing number of network threats.

As a first step, TechGuard deployed a firewall platform to guard our own company network. The success of this platform led to the realization of TechGuard’s vision for future security solutions such as the Great Walls of Fire® and PoliWall® security product suite. In 2013 TechGuard’s products division became Bandura®, LLC, a wholly-owned subsidiary of TechGuard Security.


TechGuard cyber services have been deployed for over a decade for DoD and the intelligence community, and our disruptive technology and lab services now range from nanotechnology and artificial intelligence products, to vulnerability research, malware analysis and tool development. TechGuard has filed for over fifty patents which are issued or pending in the US and internationally. TechGuardians ® address the current challenges of cyber security and privacy, specifically the problems of information management, network vulnerabilities, firewall integrity and network security concerns created by e-commerce initiatives, global Internet connections and cyber terrorism.

Today, TechGuard is recognized for:

  • Our thought leadership in Network Security
  • The excellence of our Mission-Focused TechGuardian® team, a respected group of security and engineering professionals
  • Award-winning Cyber Security Solutions through our innovative research and speedy development, from concept to delivery TechGuard’s position as a leading cyber-defense contractor.
  • Consulting Services and training for the Department of Defense (DoD), Department of Homeland Security (DHS) and US Intelligence, as well as other federal, financial and healthcare communities.
