Achieving and maintaining compliance for federal systems.
The NIST Risk Management Framework (RMF) provides a mandatory, structured process for managing security and privacy risk for federal information systems. Implementing RMF is essential for government agencies and contractors handling federal data to achieve an Authority to Operate (ATO).
Experienced assessors with deep history supporting DoD, civilian agency, and FedRAMP authorization packages.

Overview
What this engagement looks like
Maverc offers comprehensive RMF support services, guiding organizations through each step of the RMF lifecycle — Categorize, Select, Implement, Assess, Authorize, and Monitor. Our experts help you categorize systems, select and implement controls, conduct assessments, authorize systems, and establish continuous monitoring programs, ensuring compliance with FISMA and NIST standards (such as SP 800-53 and applicable DISA STIGs).
Outcomes you'll see
Authorization packages your AO will actually sign — first review
Defensible Security Assessment Reports backed by tested evidence
SSPs that match implementation, not aspiration
Realistic, risk-prioritized POA&Ms that close on schedule
Continuous monitoring that catches drift before the next audit
Reduced reassessment burden through reusable control evidence
Capabilities
What's included
Each engagement is scoped to your environment — these are the building blocks we draw from.
RMF Step 1 — Prepare: organizational and system-level risk framing
RMF Step 2 — Categorize: FIPS 199 impact analysis and system boundary definition
System Security Plan (SSP) authoring and maintenance
POA&M development, prioritization, and remediation tracking
Privacy control assessments (NIST SP 800-53A)
FedRAMP Moderate / High readiness and 3PAO coordination
FISMA reporting and CIO/IG metric support
DoD RMF (eMASS) package authoring and assessment
Inheritance mapping for cloud service offerings (CSO) and common control providers
Why Maverc
What makes this different
Assessor-grade rigor
Our team has served as both 3PAO assessors and ISSO-side defenders. We know exactly what evidence holds up under independent review — and we build packages to that standard from day one.
Engineered controls, not paper controls
We don't write SSP narratives that don't match the system. Our engineers implement the control, capture the evidence, and only then describe it — so what's on paper is what's actually running.
eMASS, Xacta, and CSAM fluent
We work natively in the GRC tooling your agency or sponsor already uses. No re-keying, no parallel spreadsheets, no surprises at the AO briefing.
Reusable across frameworks
Our 800-53 evidence is cross-mapped to CMMC, FedRAMP, SOC 2, and ISO 27001 — collect once, reuse everywhere your authorization scope grows.
Deep Dive
Where we go further
FIPS 199 categorization done right
The single most consequential decision in your RMF journey is impact categorization — get it wrong and you over-engineer (burning budget) or under-engineer (failing assessment). We facilitate categorization workshops grounded in real mission impact analysis, not checkbox guesses.
SSPs that survive independent assessment
Most SSPs fail because the narrative describes a control that isn't actually implemented. We pair every control response with tested evidence, inheritance citations, and parameter values — so when the SCA arrives, the package speaks for itself.
ConMon that's actually continuous
Continuous monitoring is where most authorization packages decay. We build ConMon programs around automated evidence collection, monthly POA&M cadence, and annual assessment refreshes — keeping your ATO defensible through its full term.
Methodology
Our end-to-end process
A proven, repeatable methodology aligned to PTES, OWASP, NIST 800-115, and MITRE ATT&CK.
01
Prepare
Organizational risk frame and roles assignment
System and authorization boundary definition
Common control identification and inheritance planning
Stakeholder kickoff with AO, ISSO, ISSM, and SO
02
Categorize
FIPS 199 impact analysis (Confidentiality, Integrity, Availability)
Define the system boundary, complete FIPS 199 categorization, and tailor the appropriate 800-53 Rev. 5 baseline with required overlays (Privacy, CUI, High-Value Asset, etc.).
02
Implement & Document
Engineer the technical, operational, and management controls. Author the SSP with control responses that match real implementation and inherited control evidence.
03
Assess, Authorize & Monitor
Conduct the independent SCA, deliver the SAR and POA&M, support the AO authorization decision, then operate continuous monitoring through the system lifecycle.
FAQ
Common questions
What are the steps in the NIST RMF process?
The RMF (NIST SP 800-37 Rev. 2) consists of seven steps: Prepare, Categorize, Select, Implement, Assess, Authorize, and Monitor. Maverc supports every step end-to-end or as targeted assistance.
Who needs to follow the RMF?
All U.S. federal agencies must follow the RMF for their information systems under FISMA. Contractors operating systems on behalf of agencies, FedRAMP cloud service providers, and DoD contractors handling federal data are also required to comply.
What is an Authority to Operate (ATO)?
An ATO is the official management decision issued by an Authorizing Official (AO) to authorize operation of an information system and explicitly accept the residual risk based on the implemented controls and assessment results.
How does RMF relate to FISMA?
FISMA requires federal agencies to implement information security programs. The NIST RMF — built on NIST SP 800-37, 800-53, 800-53A, and 800-60 — is the mandatory framework agencies use to meet those FISMA requirements.
Can you serve as an independent Security Control Assessor (SCA)?
Yes. Our senior assessors regularly perform independent SCAs and produce Security Assessment Reports (SARs) that hold up to AO and IG scrutiny. Independence requirements are honored — we don't assess controls we engineered.
Do you work in eMASS, Xacta, or CSAM?
Yes. We author and maintain authorization packages directly in the GRC tooling your agency or sponsor uses, including eMASS for DoD, Xacta 360, RegScale, and CSAM for civilian agencies.
How long does a typical ATO take?
For a Moderate-impact system with a reasonable starting baseline, expect 4–9 months from Prepare to ATO. High-impact systems, FedRAMP authorizations, and packages with significant remediation can run 9–18 months.
