Federal & Defense / FOCUSED SERVICE

NIST SP 800-53 Rev. 5

Control selection and tailoring, assessment against the official procedures, and a complete authorization package built to NIST 800-53 for federal systems.

WHAT THIS SERVICE ADDRESSES

The challenge behind the engagement.

This service is for a federal system owner or contractor building or renewing an authorization package under the Risk Management Framework. We start from where you are: your system’s impact level, the information it handles, its boundary, and any controls you inherit from a provider. We choose and tailor the right control baseline for your system, apply any agency-specific additions, and fold in the latest control updates. We assess each control with the official examine, interview, and test procedures and write implementation statements backed by real configuration evidence and a clear provider-responsibility split. Then we assemble the full package: the system security plan, the assessment plan and report, the remediation plan, the risk assessment, and a continuous-monitoring plan, in the format your agency’s tool accepts. Your authorizing official decides; we do not issue the authorization.

WHEN THIS IS THE RIGHT FIT

System security officers, program managers, and contractors who must deliver an authorization package to an authorizing official for a federal system. Also teams that need a current control set for a new system, an agency-specific addition, or a renewal.

THE WORK BEHIND THE SERVICE

What we do.
What you can use.

Categorize the system and pick the baseline

We begin with the mission owner’s impact-level decision, the information the system handles, the boundary diagram, and any prior authorization artifacts. We select the right control baseline, apply agency additions and the parameters your agency sets, mark what is inherited from your hosting provider, and deliver a tailored control set.

Assess and implement control by control

For each control we run the official examine, interview, and test procedures with its owner and record the determination. We write the implementation statement against live evidence: hardening results, infrastructure defined as code, access policies, and how logging is configured. Gaps land in the remediation plan with an owner, a milestone, and a fix.

Assemble the package for your authorizing official

You receive the system security plan, the assessment plan and report, the remediation plan, the risk assessment, and the contingency, incident-response, and continuous-monitoring plans, entered in your agency’s tool or exported in the machine-readable format it accepts. After remediation we reassess the closed controls and update the report with dated evidence.

IS THIS THE RIGHT ENGAGEMENT?

Who it’s for.
When you need it.

BEST SUITED FOR
  • Information system security officers assembling an RMF authorization package for a federal system
  • Program managers who must deliver an SSP, SAP, SAR, and POA&M to an authorizing official
  • Contractors operating a federal system that needs a Release 5.2.0 control set
  • Teams entering packages through eMASS, Xacta, or ServiceNow for agency review
WHEN IT’S TIME TO ENGAGE
  • A new system must be categorized and authorized before it goes live
  • An existing authorization is up for renewal or a significant change occurred
  • An agency overlay or ODP decision pulls in the Release 5.2.0 additions
  • Your authorizing official expects a machine-readable package for the agency GRC tool
AGREED AROUND YOUR ENVIRONMENT

What the scope can include.

  • Review the impact level, the information types, and the authorization boundary

  • Select and tailor the control baseline with agency additions and set parameters

  • Fold in the latest control updates where your agency or an addition selects them

  • Assess each control with the official procedures and written determinations

  • Map inherited controls and write the provider-responsibility split for hosted services

  • Assemble the package for your agency’s tool, with a machine-readable export where accepted

TRANSPARENT PRICING

What it typically costs.
One rate: $150/hour.

Every engagement is priced by the hours it takes at one flat rate, with scoping, the work, and the final deliverables included. Find the size closest to yours.

Small
$18,000–$30,000

One system at the Low baseline, mostly cloud-hosted

About 120–200 hours
Mid-size
$33,000–$54,000

One system at the Moderate baseline with several connected services

About 220–360 hours
Large
$54,000–$90,000

High baseline, or several systems sharing one authorization package

About 360–600 hours
WHAT MOVES THE PRICE
  • Baseline selected (Low, Moderate, or High) and resulting control count
  • Number of systems and inherited controls from a cloud provider
  • Existing policies, procedures, and evidence
  • Agency-specific overlays or tailoring requirements
TYPICAL TIMELINE

2–5 months depending on baseline and number of systems

Independent control assessment and the authorizing official's review are separate; third-party assessments of a Low system are quoted around $10,000–$20,000 and rise steeply at Moderate and High.

Ranges are planning estimates at $150/hour, not a quote. Your price is confirmed in writing after a scoping call, before any work begins.

TANGIBLE DELIVERABLES

What you take forward.

  • Categorization memo and tailored control set with parameters and inheritance marked
  • Assessment plan and report with a determination for every control
  • System security plan, remediation plan, risk assessment, and continuous-monitoring plan
  • Machine-readable package files when your agency or its platform accepts them

Final coverage, deliverables, timing, and any retesting or implementation work are confirmed before the engagement begins.

SERVICE-SPECIFIC QUESTIONS

Before we get started.

Do we need to adopt the latest control release now?

Check your agency’s direction first, then plan for it either way. The most recent update added a few new controls and revised one, and updated the matching assessment procedures, but it did not change the baselines. So an existing moderate or high package does not grow on its own; the new controls matter when your agency or an added control set selects them. We record the change in your tailored control set, note which items your authorizing official has adopted, and keep your plan consistent with the official versions of the catalog.

How much can we inherit from our cloud hosting provider?

Much of the physical, environmental, and infrastructure controls, and less of what you configure yourself. The provider’s authorization package and responsibility matrix state which controls are fully inherited, shared, or entirely yours. We read that matrix against your architecture, mark each control in your plan as inherited, shared, or customer, and write the customer half of every shared control, such as the access policies, key management, and logging you configure. Authorizing officials expect that split to be explicit, and an inheritance claim without the provider’s authorization behind it is one an assessor will challenge.
