About
Founded on service.
Built for results.
Infinity Shield L.L.C. is a Service-Disabled Veteran-Owned network engineering and cybersecurity consultancy.
Founded by Dr. Chris Opp (DIT, CISSP), Infinity Shield brings over 28 years of federal, DoD, and enterprise technology leadership to every engagement. Dr. Opp's background is in network architecture: enterprise SD-WAN, data center design, and routing and switching at federal scale. The cybersecurity and compliance work is built on that foundation.
We design and build networks that perform from day one and hold up under attack. Our work covers enterprise network design, cloud architecture, Zero Trust implementations, and NIST and CMMC compliance programs for federal contractors, small businesses, and managed service providers.
