01
Define the requirement
Clarify the system boundary, mission context, applicable requirements, roles, access and expected outputs.

Federal Cybersecurity Delivery
System Requirements.
Clear Evidence and Ownership.
Security work needs more than a completed document. We connect the system context, control responsibilities, assessment evidence and remediation activity so your team can review results and keep work moving.
How We Approach the Work
From System Context
to Reviewable Results.
02
Organize the evidence
Review available artifacts, identify gaps and agree on the evidence and personnel needed for the work.
03
Perform the scoped work
Maintain documentation, assess controls, analyze vulnerabilities or review policy against the agreed requirements.
04
Report and follow through
Deliver traceable findings, document open issues and coordinate agreed remediation validation or artifact updates.
Roles and Boundaries Are Established First
We agree on assessment independence, authorized access, evidence handling and review responsibilities before work begins. Authorization decisions and acceptance of residual risk remain with the responsible officials.
Grounded in Applicable Requirements
We trace the agreed work to the agency’s direction, system boundary and applicable contract requirements. The official resources below help distinguish lifecycle guidance, control catalogs, assessment methods, federal standards, agency policy and cloud-program rules.
Official Government Resources
Know the Requirement.
Use the Right Reference.
Practical starting points for ISSO, RMF, assessment, vulnerability and policy work. We establish which requirements apply to the agency, system, contract and service scope before using these references.
Lifecycle guidance
NIST Risk Management Framework
SP 800-37 Rev. 2 · Final, December 2018
Use the RMF lifecycle to connect system categorization, selected controls, assessment evidence, authorization inputs and continuous monitoring.
Planning guidance
NIST System Planning
SP 800-18 Rev. 2 · Final, June 2026
A reference for system security, privacy and supply-chain plans: system purpose, control implementation and assigned responsibilities.
Control catalog
NIST Security & Privacy Controls
SP 800-53 Rev. 5 · Release 5.2.0
Map scoped requirements and policy language to control objectives. Select and tailor controls for the system rather than treating the entire catalog as a universal checklist.
Assessment guidance
NIST Control Assessment
SP 800-53A Rev. 5 · Release 5.2.0
Plan evidence requests and examine, interview and test methods; record findings against the applicable assessment objectives.
Vulnerability and patch guidance
NIST Enterprise Patch Management
SP 800-40 Rev. 4 · Final, April 2022
Connect patch identification and prioritization to deployment planning and follow-up verification in the mission environment.
Federal cloud program rules
FedRAMP Cloud Security Resources
Consolidated Rules for 2026
Review the applicable Rev5 or 20x path, offering scope, stakeholder responsibilities and transition dates. Cloud program status and an agency’s authorization decision are distinct.
Federal standard
Federal Security Categorization
FIPS 199 · Final, February 2004
A standard for categorizing federal information and systems by potential confidentiality, integrity and availability impacts, within its defined scope.
Federal agency policy
OMB Information Resource Policy
Circular A-130 · July 2016 edition
Review agency governance, information-security and privacy responsibilities when tracing policy requirements to system procedures. Confirm current agency direction and contractual responsibilities.
Guidance, requirements and authorization have different roles.
Statutes establish legal obligations; agency policies and applicable federal standards define requirements within their scope. NIST guidance supports implementation and assessment. Contract terms, system type and agency direction determine applicability—these references are not a universal checklist.
FedRAMP’s current resources distinguish cloud-service certification from an agency Authorization to Operate (ATO). FedRAMP does not grant agency ATOs. These links describe resources used to scope work; they do not claim CDG certification, FedRAMP authorization, recognized-assessor status or government endorsement.

Common Questions
Federal Security Support
Your Questions, Answered.
Where does delivery start?
We start with the system, mission, applicable security requirements, current artifacts and the work you need completed.
How are assessment roles established?
The engagement defines assessment scope, methods, authorized access, evidence handling and any independence requirements before assessment activity begins.
What should we share in an initial enquiry?
Describe the service area, high-level system context, deliverables and timeline. Use the initial enquiry for non-sensitive information; access and evidence-handling arrangements are established separately.
