FedRAMP Consultant for Cloud Service Providers
Expert guidance from the team that brought the first CSP through FedRAMP 20x, paired with the Artemis™ Platform so you own the SSP, the evidence, and the program after ATO.
Why Most FedRAMP Consulting Engagements Stall
The traditional consulting model was built for an era of paper SSPs and hourly billing. CSPs pursuing FedRAMP today need something different.
The consultant owns the SSP
When the engagement ends, the documentation, evidence model, and tribal knowledge walk out the door. You're left with a PDF and a renewal quote.
Generalists miss 20x
FedRAMP 20x and OSCAL are reshaping the program. Most consultants are still optimizing for the Rev 5 paper workflow they learned five years ago.
Hourly billing creates drag
When every meeting is billable, scope creeps. Six-figure retainers turn into seven-figure programs that still depend on the consultant after ATO.
How SunStone Consults
Targeted expert services on top of the Artemis Platform. You buy the help you need, not a multi-year retainer.
Boundary & baseline scoping
Decide what's in the authorization boundary, which baseline applies, and how to size the program before you spend a dollar on assessment.
SSP & evidence authoring
Hands-on help writing implementation statements and assembling the evidence pack, all inside the Artemis Platform so you keep the work product.
Agency & PMO support
Sponsor strategy, kickoff meetings, and PMO reviews. We've sat at those tables and know what reviewers actually want to see.
3PAO readiness
Mock assessments and evidence walk-throughs so the actual SAR is a confirmation, not a discovery exercise.
Traditional Consultant vs SunStone
How the two engagement models compare on cost, ownership, and time to ATO.
| Traditional Consultant | SunStone | |
|---|---|---|
| Engagement model | Hourly retainer, multi-year | À la carte expert services + platform |
| 3-year cost | $1.5M–$3M | Fraction of consultant cost |
| Time to ATO | 12–24 months | 60–90 days authorization-ready |
| FedRAMP 20x and OSCAL fluency | Rare | Core expertise |
| You own the SSP and evidence |
Who We Work With
Cloud Service Providers pursuing their first FedRAMP authorization, CSPs migrating from Rev 5 to 20x, and authorized providers who want to take Continuous Monitoring back in-house from a legacy consulting firm.
Most of our engagements pair targeted expert services with the Artemis Platform. After authorization, your team runs the program on the platform with light-touch Office Hours rather than a permanent consulting footprint.

Frequently Asked Questions
What does a FedRAMP consultant actually do?
A FedRAMP consultant guides a Cloud Service Provider through authorization: scoping the boundary, writing the System Security Plan, preparing for the 3PAO assessment, and managing the agency or PMO relationship. The work spans technical, procedural, and program-management territory.
How is SunStone different from a traditional FedRAMP consultant?
Traditional consultants bill by the hour and own the documentation, which means you keep paying long after ATO and never fully own your compliance program. SunStone pairs targeted expert services with the Artemis Platform, so the SSP, evidence, and Continuous Monitoring workflow stay with you.
Do we need a consultant if we already have the Artemis Platform?
Not always. Many CSPs run authorization on the Artemis Platform with light-touch Office Hours support. Others want a hands-on engagement for boundary scoping, agency sponsorship strategy, or 3PAO readiness. We sell the services à la carte so you only pay for what you actually need.
Can you help with FedRAMP 20x?
Yes. SunStone is one of the most active voices in the 20x community and brought the first CSP through the new pathway. We support both Rev 5 and 20x engagements.
What does an engagement typically cost?
Significantly less than a traditional consulting firm because the platform does the heavy lifting. Pricing depends on scope, timeline, and which expert services you need. Schedule a call and we'll size it against your actual situation.
