FedRAMP and CMMC
with the SunStone Artemis™
Platform

FedRAMP (Federal Risk and Authorization Management Program) is a government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services. Any cloud service provider (CSP) that wants to sell to federal agencies needs FedRAMP authorization, it's essentially the 'seal of approval' that your cloud offering meets federal security requirements.

FedRAMP Rev5 is the current baseline aligned with NIST 800-53 Revision 5, featuring comprehensive control requirements across Low, Moderate, and High impact levels. FedRAMP 20x is a new streamlined authorization pilot designed for modern cloud-native applications, it emphasizes automation, continuous monitoring, and machine-readable security artifacts (OSCAL) to dramatically reduce authorization timelines from months to weeks. The Artemis Platform supports both pathways with AI-native documentation and evidence collection.

Traditional FedRAMP Rev5 authorization can take 12-18 months and cost $1-3 million using manual consulting approaches. FedRAMP 20x aims to reduce this to weeks for qualifying cloud-native systems. With the Artemis Platform, we've helped organizations achieve their Authority to Operate (ATO) in as little as 3-4 months on Rev5, and we're actively supporting early 20x adopters with OSCAL-native automation.

CMMC (Cybersecurity Maturity Model Certification) Level 2 is required for defense contractors handling Controlled Unclassified Information (CUI). It aligns with NIST SP 800-171 and requires implementation of 110 security practices. Unlike self-attestation, Level 2 requires third-party assessment by a C3PAO (Certified Third-Party Assessment Organization).

The Artemis Platform uses AI-native technology trained on FedRAMP Rev5, FedRAMP 20x, and CMMC requirements to generate your System Security Plan (SSP), Plan of Action and Milestones (POA&M), and all supporting artifacts in both traditional and OSCAL formats. It ingests data from your existing infrastructure and GRC tools, identifies gaps, and produces audit-ready documentation, eliminating months of manual document creation.

For FedRAMP, a Third-Party Assessment Organization (3PAO) conducts an independent security assessment of your cloud system. For CMMC, a Certified Third-Party Assessment Organization (C3PAO) performs a similar role. Both review your documentation (SSP, POA&M, policies & procedures), test your security controls, and validate that your implementation meets the respective framework requirements. The Artemis Platform prepares you with complete, consistent documentation that streamlines either assessment process.

After achieving your FedRAMP ATO or CMMC certification, ongoing monitoring is required to maintain compliance. FedRAMP requires monthly vulnerability scans, annual assessments, and regular ConMon reporting to your authorizing agency, with FedRAMP 20x placing even greater emphasis on automated, real-time monitoring. CMMC requires annual affirmation and continuous evidence of control effectiveness. The Artemis Platform automates both by continuously monitoring your security posture, detecting drift from your baseline, and generating required reports automatically.

FedRAMP Rev5: Authorizations require annual assessments including continuous monitoring. Moderate and High systems need annual Red Team exercises plus penetration testing. Significant changes to system architecture, security boundaries, or controls trigger reauthorization reviews. While there's no fixed expiration, ongoing compliance must be demonstrated through continuous monitoring reports to Authorizing Officials.

FedRAMP 20x: Currently in pilot, will emphasize continuous authorization through automated monitoring and machine-readable evidence, with Ongoing Authorization Reports required every 3 months, shifting compliance from document-driven to data-driven processes.

CMMC Level 2: Certifications expire after three years, requiring C3PAO or self-assessment (depending on contract). Annual affirmations must be submitted in SPRS between certifications, and POA&Ms under Conditional Status must close within 180 days. Material changes, security incidents indicating control failures, or compliance misrepresentation can trigger decertification before the three-year cycle.

The Artemis Platform helps you stay ahead of these requirements with continuous documentation updates and automated compliance tracking.
