MCT Security is the protection-focused pivot of Mansfield Computing Technology, LLC — a family business rooted in national security, telecommunications, and critical infrastructure. Seventy years of engineering rigor and operational experience, narrowed to a single charter: making our clients, and their communities, safer.
Mansfield Computing Technology was a general technology practice — telecom engineering, enterprise architecture, and the unglamorous infrastructure work that keeps complex organizations standing. MCT Security is its evolution: the same engineers, the same methodology, the same discipline, redirected to the protection of our clients and the communities they serve.
We kept the engineering. Decades of telecom and critical-infrastructure work taught us how systems actually fail — and how to design for what comes after the first thing breaks. That instinct now lives inside every security engagement we run, whether we're embedded as your CSO, in command during a crisis, or capturing field documentation from 400 feet up.
We narrowed the focus. Protection isn't a side practice for us anymore. It's the charter. Everything else — the technology depth, the cross-vertical reach, the AI work, the executive advisory — exists to serve that.
A practice built generation by generation — telecom engineering, crisis engineering, strategic design and planning, and now a singular focus on protection.
Mansfield Computing Technology was founded on four decades of research, innovation, and leadership in the telecommunications industry — backed by military rigor and the process discipline that comes with running critical infrastructure. The work was rarely glamorous; the consequences of getting it wrong were always real.
That foundation evolved into thirty years of technology and security work — proactive and reactive, across adversary tiers up to and including nation-state actors. Sharpened by experience inside the Special Operations community, and informed by designing enterprise and security portfolios across every vertical we work in today. We learned what holds up under pressure, and what doesn't.
MCT Security is the charter that came next: the same engineers, the same methodology, narrowed to a single purpose. We exist to make our clients, and the communities they operate in, safer — regardless of the realm.
Three commitments that fall out of the heritage above.
Decades of building things that have to work in the field means we don't hand you a deck and disappear. The deliverable is what you do with it on Monday morning.
No junior associate handoff, no offshore back-bench. The person on the kickoff call is the person doing the work and the person on the readout.
Family-business roots, military rigor, and a Special Operations sensibility around what gets said and what doesn't. Deep experience keeping clients out of the news — and off the congressional register.
