FedRAMP Compliance Software for Cloud Service Providers
The Artemis™ Platform maps every FedRAMP Low, Moderate, and High control to its evidence in one workspace, built on OSCAL by the team that brought the first CSP through FedRAMP 20x.
Why DIY and Consultants Both Fall Short
FedRAMP Moderate has 323 controls and demands continuous evidence after ATO. Most teams reach for tools that weren't built for it.
Spreadsheets break at Moderate
323 controls, thousands of assessment objectives, and version-controlled evidence don't fit in Excel. Teams lose track between ConMon submissions.
Consultants bill by the hour, forever
Traditional FedRAMP consultants charge $500K–$2M to get to ATO and keep billing for ConMon. You never own the SSP, the evidence, or the workflow.
Audits fail on evidence, not controls
3PAOs rarely fail you on what you do. They fail you on what you can't prove. Without a system of record, evidence gaps surface during the assessment.
What the Artemis Platform Does for FedRAMP
A single workspace covering every Low, Moderate, and High control, plus the evidence that proves them.
Control-by-control mapping
Low (156), Moderate (323), High (410). Each control mapped to objectives, owners, and implementation status.
Evidence collection & versioning
Centralized evidence with version history so 3PAOs see exactly what was in place and when.
Continuous Monitoring
Run monthly ConMon and annual assessments from the same source of truth. No more ATO-then-scramble.
OSCAL-native exports
Generate SSPs, POA&Ms, and SAR-ready artifacts in OSCAL, the format FedRAMP 20x is built on.
Spreadsheets vs Consultant vs the Artemis Platform
How the three common approaches stack up on cost, speed, and audit risk.
| Spreadsheets | Consultant | Artemis Platform | |
|---|---|---|---|
| 3-year cost | Hidden labor cost | $1.5M–$3M | Fraction of consultant cost |
| Time to authorization-ready | 12–24 months | 9–18 months | 60–90 days |
| Audit risk | High (evidence gaps) | Medium (vendor-dependent) | Low (system of record) |
| Ongoing ConMon | Manual, error-prone | Outsourced indefinitely | In-platform |
| You own the SSP and evidence |
Who the Artemis Platform Is Built For
Cloud Service Providers pursuing FedRAMP Low, Moderate, or High authorization, plus teams already authorized who need to run Continuous Monitoring without a permanent consultant footprint. FedRAMP 20x is supported natively for CSPs preparing for the new pathway.
Without compliance software, most CSPs need 3+ FTEs after authorization just to maintain their ATO. The Artemis Platform brings that down to a fraction of an FTE so your engineers can focus on shipping product instead of collecting evidence.

Frequently Asked Questions
Does the Artemis Platform cover all FedRAMP Moderate controls?
Yes. The Artemis Platform maps every one of the 323 FedRAMP Moderate controls (NIST SP 800-53 Rev 5) to evidence, policy text, and implementation statements, and supports Low and High baselines as well.
Is the Artemis Platform a replacement for a 3PAO?
No. 3PAOs are accredited assessment organizations required for FedRAMP authorization. The Artemis Platform is the software you use to get authorization-ready and to maintain Continuous Monitoring after ATO, which makes the 3PAO engagement faster and lower-risk.
How fast can we be authorization-ready?
Most CSPs using the Artemis Platform are authorization-ready in 60–90 days, versus 12–24 months for spreadsheet- or consultant-led approaches. Your timeline depends on the maturity of your existing security stack.
Does the Artemis Platform support FedRAMP 20x?
Yes. The Artemis Platform is built on OSCAL from the ground up, which is the foundation of FedRAMP 20x. We work with both Rev 5 and 20x baselines and the SunStone team is one of the most active voices in the 20x community.
What does the Artemis Platform replace in our current toolset?
The Artemis Platform replaces GRC spreadsheets, shared drives full of evidence, and most of what a consultant charges a six-figure retainer for. It works alongside your existing security tooling, a compliance workspace, not an EDR or SIEM.
