Cloud Architecture & Authorization

Some data is treated as too sensitive for commercial cloud.
We have spent a decade proving otherwise.

Stigian works in the intersection of industrial IoT and OT, cloud architecture, and cyber authorization — for the Navy's cloud enterprise and the maritime industrial base. That intersection is where digital thread programs usually stall, and where we have spent a decade.

Track Record

Our people have been present at most of the significant firsts in Navy and Department of War commercial cloud adoption — across all three major cloud providers.

01 The first Department of War–approved system to host sensitive data on commercial cloud, including its primary design and security engineering.
02 The cloud brokerage and network defense design later standardized as DISA's Secure Cloud Computing Architecture (SCCA).
03 The first U.S. Navy system to receive an ATO on public cloud.
04 The Navy's first AWS GovCloud IL4 accreditation, and its first and only Commercial Cloud Access Point — which DISA adopted as the model for the SCCA Boundary Cloud Access Point (BCAP), the mechanism governing Department of War cloud access today.
05 The first Office 365 authorization in the Department of War — the DISA Provisional Authorization, the Navy ATO issued against it, and the identity, network, and defensive cyber operations integration required to bring a commercial SaaS platform up to Navy enterprise standards.
06 The Navy's foundational commercial cloud hosting security standards and the first commercial cloud incident response plan in the Department of War.
07 The first Google Cloud and first Oracle Cloud enterprise landing zones in the U.S. Navy.
08 Zero Trust architecture for globally distributed IoT sensor collection across the U.S. Navy's public shipyards — the foundation of an enterprise industrial IoT landing zone now underway, and of the same pattern being adopted by commercial shipbuilding primes and defense manufacturers.
09 AI and ML workloads running on controlled data inside an accredited IL5 boundary, and AI coding assistants and agentic tooling approved for CUI — the same class of problem as commercial SaaS in 2014, a technology generation later.

How We Are Built

Fifteen people. Every engineer holds the title of Principal Engineer, and every engagement is staffed two to three of them deep. There is no bench of junior analysts learning on the client's clock, and the people who scope the work are the people who do it.

We treat AI the way we treat security: not as a separate practice, but woven through everything — how we deliver, and what we build for clients. It is a meaningful part of how a team this size moves at the pace it does.

Our work sits primarily in the Navy's cloud and architecture enterprise and across the maritime industrial base — the commercial shipbuilding primes and the companies that build and sustain the fleet. We take adjacent defense and critical-infrastructure work selectively, where the judgment transfers.

The major cloud providers tend to route work to us when the problem is the complicated version of itself. That is the practice we have built, and the only one we want.
