01
NIST RMF & FISMA Support
Support system categorization, control selection and tailoring, implementation statements, assessment preparation, authorization packages, and ongoing authorization activities using NIST SP 800-37 and 800-53.
COMPLIANCE & ADVISORY SERVICES
Translate Compliance Requirements into Defensible Control Evidence.
RadialByte helps organizations interpret applicable security requirements, assess control implementation, prepare assessment documentation, and resolve compliance gaps across federal and commercial frameworks.
THE CHALLENGE
Compliance findings often begin with unclear control ownership and insufficient evidence.
Organizations must demonstrate not only that security controls are documented, but that they are implemented, assigned to responsible owners, and supported by current evidence. Gaps in system boundaries, control narratives, inheritance, testing records, and remediation tracking can delay assessments and complicate audit responses.
RadialByte reviews requirements against actual control practices, identifies missing or inconsistent evidence, and helps control owners prepare traceable documentation and corrective actions.
OUR COMPLIANCE & ADVISORY SERVICES
Focused support across the assessment lifecycle
Our work is scoped to the frameworks, system boundaries, control responsibilities, and assessment milestones that apply to your organization.

03
CMMC & NIST SP 800-171 Readiness
Assess applicable contractor security requirements, document control implementation gaps, review CUI protection practices, and develop prioritized remediation plans for assessment readiness.
04
Control Gap Assessments
Map policies, technical settings, procedures, and operational records to selected control requirements; document deficiencies, evidence limitations, and corrective actions.
05
SSP, POA&M & Evidence Development
Develop or refine System Security Plans, control matrices, evidence inventories, risk assessment documentation, and Plans of Action and Milestones with owners and target dates.
06
Audit & Continuous Monitoring Support
Coordinate evidence requests, track assessment findings, maintain compliance calendars, review recurring control evidence, and report the status of outstanding remediation commitments.
WHAT YOU RECEIVE
Assessment-ready documentation and a clear remediation record
Deliverables are selected according to the applicable framework, assessment scope, and maturity of existing compliance artifacts.
- Requirements-to-controls mapping and documented applicability decisions
- Control implementation gap assessment with supporting observations
- Updated SSP narratives and control responsibility assignments
- Evidence request matrix identifying sources, owners, and collection status
- POA&M register with corrective actions, milestones, and validation criteria
- Assessment readiness summary and prioritized compliance action plan
OUR APPROACH
A structured path to assessment readiness
We align the compliance workplan to the assessment boundary, applicable control set, evidence requirements, and target review dates.
01
Define Scope
Confirm the framework, system boundary, data types, inherited controls, stakeholders, and assessment schedule.
02
Review Controls
Examine implementation narratives, policies, configurations, procedures, and available evidence against control requirements.
03
Close Gaps
Assign findings, update documentation, establish remediation milestones, and collect evidence of corrective actions.
04
Prepare & Sustain
Organize assessment artifacts, support assessor requests, and establish recurring evidence and POA&M reviews.
COMPLIANCE & ADVISORY FAQS
Common questions about compliance assessments
Practical considerations when preparing for a framework assessment, audit, or authorization review.
Can RadialByte help us prepare for a NIST RMF authorization?
Yes. We can support security categorization, control documentation, SSP and assessment artifact development, POA&M preparation, and continuous-monitoring planning. The Authorizing Official retains the authorization decision.
Can you help us determine which controls apply to our environment?
We review the relevant framework, system boundary, information types, contractual requirements, and inherited controls to develop an applicability and responsibility mapping for review by your designated stakeholders.
Do we need to replace our existing compliance or GRC platform?
No. We can work with your current GRC system, evidence repository, spreadsheets, and ticketing workflows, provided they support the required documentation, ownership, and audit trail.
Can RadialByte support CMMC readiness without acting as the assessor?
Yes. We provide advisory readiness reviews, control gap documentation, evidence preparation, and remediation planning. Independent assessments and certification decisions remain with authorized assessment bodies.
How do you manage open audit findings and POA&Ms?
We help document each finding, identify the affected requirement and owner, define corrective actions and milestones, collect closure evidence, and report overdue items and residual risks for management review.
