Most of our enterprise delivery has been as a specialist subcontractor to prime integrators. Those contracts do not permit us to name the end client and we will not break them to win a deal — the same discipline you would want applied to your name.
So we substitute things you can inspect. The code: our reference CIS-benchmarked OCI landing zone is published publicly. The architecture: the notes above carry the real topology, constraints and tooling. The people: 27 certifications, named engineers.
Our prime-side delivery leads will speak to you directly, under NDA, on request. If a named logo matters more to you than any of that, we are probably not the right firm — and a large integrator will be glad to show you theirs.
