RMF Lifecycle & ATO Support
We handle categorization, control implementation, package development, and the push through assessment and authorization.

Services
RMF work that moves the authorization forward.
Glacier Byte joins defense programs to lead the authorization package, support the assessment, and maintain the work after the ATO. We can take the full lifecycle or a defined workstream.
Discuss the program Scope of work
Choose the support the program needs.
A program may need one owner from categorization through monitoring. It may need a narrower scope: repairing a package, preparing for assessment, or owning sustainment after authorization.
Continuous Monitoring & ATO Sustainment
We maintain the POA&M, evidence, monitoring reports, and reauthorization work that keep the ATO current.
POA&M Management · ConMon Reporting · Reauthorization Support
Compliance Documentation
System Security Plans, POA&Ms, policies, and evidence written for the people who implement and assess them.
System Security Plans · Policy Development · Evidence Collection
Security Assessments
Assessments against your NIST 800-53 baseline, with findings tied to owners, remediation steps, and due dates.
Control Validation · Vulnerability Assessments · Audit Preparation
Infrastructure Hardening
We apply and document STIG and SRG settings, resolve scan findings, and maintain the hardened configuration as the system changes.
STIG Compliance · Vulnerability Management · Security Automation
Air-Gapped SIEM Implementation
We deploy and configure Splunk or the Elastic Stack inside disconnected environments, from log onboarding and detection content through hardening and operational handoff.
SIEM Architecture & Sizing · Log Onboarding & Detection · Hardening & Operational Handoff
Secure AI & Systems Integration
We bring AI and new system components into the program boundary, then handle integration, hardening, evidence, and authorization under the existing RMF process.

Working together
Questions about scope and handoff.
What program teams usually ask before bringing us into the work.
Can you join an RMF effort that is already underway?
Yes. We review the boundary, baseline, package, open findings, and assessment history, then identify the work that needs an owner. A program does not need to restart the RMF process to bring us in.
Do you need to own the full RMF lifecycle?
No. We can lead the full lifecycle or take a defined scope such as package development, assessment support, POA&M management, hardening, or continuous monitoring.
What do you deliver?
Deliverables depend on scope, but commonly include the SSP, control implementation narratives, evidence records, POA&Ms, assessment responses, policies, hardening records, and continuous monitoring reports.
Do you support eMASS workflows?
Yes. We prepare and maintain control responses, artifacts, findings, and authorization records for review in eMASS, following the customer’s access and approval process.
How do you work with primes and program teams?
We work inside the program with engineering, security, delivery, and leadership. The people attending working sessions are the same people responsible for the package and follow-up actions.
Do you stay involved after the ATO?
Yes. We maintain evidence, track POA&Ms, support scanning and remediation, document system changes, prepare continuous monitoring reports, and support reauthorization.
What do you need to scope an engagement?
We start with the system boundary, control baseline, current package status, known findings, assessor feedback, target deadline, and the outcome the program needs next.
Start where the work stands
Bring the package, the deadline, and the open questions.
We will review the current state, identify the first decision or gap holding up the work, and define a practical scope with your team.
