The decision that sets the price.

Security Architecture and Control Design

Scope, boundary and control design determine what a compliance program costs more than any other decision, and they are usually made quickly, early, by whoever was available. We treat them as the engineering problem they are, and we own the design.

Talk through your target state

What you receive

A defined boundary

A shared responsibility matrix

Control specifications

Where regulated data lives, where it moves, and what is legitimately out of scope, with a written basis for the line so it holds when a prime or an assessor pushes on it.

Control specifications

A shared responsibility matrix

Control specifications

We write them, in the language the assessment objectives use, so a requirement traces to a specification, a specification traces to a configuration, and nobody has to guess what compliant looks like.

A shared responsibility matrix

A shared responsibility matrix

A shared responsibility matrix

Every assessment objective assigned to your team, your provider, or shared. This is the document that ends the argument about who was supposed to do what, and it is the one artifact a firm that also builds cannot write credibly.

How the work runs

Set the boundary

Design the target state

Design the target state

We map where regulated data actually lives rather than where the diagram says it does. Confining it to a defined enclave, where that is possible, is usually the largest single cost reduction available to a small organization.

Control by control, what will be true when the work is finished. This is our design decision, not a menu of options for somebody else to pick from, and it is written so your team knows exactly what to build.

Review the work delivered

Validate what is delivered

Validate what is delivered

Your team implements to the specification. We review what was actually built against what we wrote, and we say plainly where it falls short, while there is still time for that to be useful.

Acceptance testing against the specification we wrote, and the evidence structure that will keep proving it a year from now.

Questions we get asked

The ones that come up most often before a scoping call.

Many can, and some do it well. The difficulty is that a provider designing the work will then be paid to perform it, and will be grading their own result afterwards. That is a reasonable arrangement for routine IT and an uncomfortable one when a contract award depends on the answer.


Whether regulated data is confined to an enclave or spread across your whole enterprise. Everything in scope has to meet the standard, be documented, and generate evidence on a cadence, so the boundary decision compounds through every later cost.


Yes. The System Security Plan describes the system against the framework, and we write it from the specification and the validated result rather than from an interview. Where a client wants a separate party to write it, we will work to that instead.


That is the intended arrangement. Specifications are written to be executed by a competent IT team rather than to require us. Several of our engagements are structured as ongoing review of an incumbent provider's work.


Yes. Helping you select an implementation partner and holding them to the specification is part of the owner's representative role, and it is often where the specification earns back its cost. We will introduce firms we have seen do good work, and we take no fee from any of them.
