Schellman has become the first Third-Party Assessment Organization (3PAO) to assess over 200 cloud service offerings on the FedRAMP Marketplace. This milestone isn't just a number; it's a dataset that reveals which decisions separate programs that move smoothly from those that stall mid-authorization.
The pattern is clear: most FedRAMP failures happen before the assessment even starts. These failures often stem from decisions about scope, resourcing, and cross-functional alignment that cloud service providers (CSPs) make without fully understanding their downstream consequences.
What the Data Shows
Schellman's assessment portfolio spans over a decade, 71 federal agencies, and more than 870 Authorities to Operate. The technology stack variety is significant: AI-powered platforms, containerized applications, multi-cloud architectures, and SaaS tools touching sensitive federal data. Across all of it, the same friction points appear regardless of company size or Impact Level.
The federal market has shifted dramatically. FedRAMP authorization is now a market access requirement. Agencies are tightening procurement policies, and CSPs without authorization are being locked out of opportunities. Executive orders on cybersecurity, zero trust mandates, and high-profile incidents have pushed agencies to scrutinize cloud tools more carefully.
At the same time, FedRAMP is undergoing its most significant modernization effort with FedRAMP 20x, which aims to automate and streamline authorization through continuous, machine-readable evidence of security controls. The shift from manually assembled documentation packages to continuous monitoring tooling changes what CSPs need to invest in now.
Key Findings from 200+ Assessments
1. Scope definition determines your timeline before you start
The authorization boundary, what's included in the FedRAMP assessment and what isn't, is the most consequential decision you'll make. Draw it too broadly and you pull in systems that add complexity without security value. Draw it too narrowly and critical data flows surface during testing, forcing reassessment.
Programs that move faster invest time upfront defining their boundary clearly, with input from both technical and compliance stakeholders. A well-defined boundary shapes every policy, procedure, and control implementation that follows. Most delays trace back to boundary decisions made without full understanding of their implications.
2. Cross-functional misalignment creates immediate, costly friction
FedRAMP touches governance, risk, and compliance teams (documentation and control mapping), engineering teams (implementing and evidencing controls), and go-to-market teams (managing agency relationships and sales timelines). When these groups aren't aligned, the friction is immediate.
Engineering implements a control one way while GRC documents it another. Sales commits to an authorization timeline that the technical team didn't agree to. The assessment stalls while teams argue over who owns what.
CSPs that navigate the process smoothly treat FedRAMP as a cross-functional program with shared ownership, a single source of truth for documentation, and clear accountability. An internal program manager or dedicated authorization lead who keeps all three functions moving in the same direction is often the difference between smooth progress and chaos.
3. Your 3PAO selection shapes agency trust in your program
Your 3PAO's assessment is what agency customers rely on to make Authority to Operate decisions. The quality, depth, and credibility of that assessment reflects directly on your program. An agency's Authorizing Official needs to trust the assessment package in front of them, and that trust flows from the 3PAO's reputation, rigor, and experience as much as from your own security posture.
A 3PAO that's assessed hundreds of programs across similar technology stacks will identify issues earlier, communicate findings more clearly, and work through remediation more efficiently. Select based on experience and fit, not just availability or price.
4. Under-resourcing predicts stalls more reliably than technical gaps
CSPs sometimes launch authorization efforts with lean teams, assuming the 3PAO can carry the weight. That's the wrong approach.
Evidence-gathering alone is substantial: policies, procedures, system diagrams, configurations, Audit Logging, Vulnerability Assessment results. Most of it has to come from inside your organization. Engineering time, security team bandwidth, and leadership availability for reviews and decisions all need to be budgeted deliberately.
Resource gaps discovered mid-assessment cost far more in both time and money than gaps addressed before the process begins. Programs that move on schedule have done honest resource assessments before kickoff, identified where the gaps are, and made deliberate decisions about hiring, backfilling, or bringing in support.
5. Engaged agency sponsors change the entire trajectory
For CSPs pursuing an Agency authorization path, the relationship with the sponsoring agency's Authorizing Official and security team is one of the most underrated variables in the process. When that relationship is active and collaborative, timelines stay on track.
An engaged agency sponsor provides early guidance on their specific requirements and risk tolerances, flags concerns before they become blockers, and helps navigate internal review processes on their end. CSPs that invest in building genuine relationships, by communicating proactively, including sponsors in key milestones, and treating them as partners rather than gatekeepers, consistently have better outcomes.
What This Means for Your Team
If you're evaluating FedRAMP authorization, the data from 200+ assessments suggests three things:
First, the security bar isn't lowering. FedRAMP 20x is designed to eliminate friction in the traditional process, but the rigor required for authorization remains high. Don't mistake modernization for an opportunity to cut corners.
Second, continuous monitoring is becoming more central. The shift toward ongoing security validation rather than point-in-time assessments means you should treat your ATO as a starting point under an increasingly continuous model. Invest in security automation and machine-readable compliance evidence now.
Third, early movers will have an advantage. As the 20x pilot expands and new authorization paths become available, CSPs that have already built mature security programs with strong automation and experienced 3PAO relationships will move through updated processes faster.
Action Items by Priority
Immediate (before you commit to a timeline):
- Define your authorization boundary with input from technical and compliance stakeholders. Document what's in scope, what's out of scope, and why.
- Conduct an honest resource assessment. Identify who will gather evidence, who will implement controls, and who will make decisions when issues surface.
- Engage a 3PAO for a readiness assessment before the formal assessment begins. Use their experience to identify gaps and plan your approach.
Short-term (during authorization planning):
- Assign a single internal program manager or authorization lead with authority to coordinate across GRC, engineering, and go-to-market teams.
- Establish a single source of truth for documentation. Decide where policies, procedures, and evidence will live and who owns updates.
- If pursuing an Agency authorization path, invest in building a genuine relationship with your sponsoring agency. Include them in key milestones and communicate proactively.
Long-term (for continuous monitoring and 20x readiness):
- Budget for ongoing investment in continuous monitoring, annual assessments, and maintaining your authorization package. These aren't one-time costs.
- Prioritize security automation and tooling that produces machine-readable evidence. This positions you for where FedRAMP 20x is heading.
- Treat agency relationships as strategic assets. The relationships you build with federal stakeholders shape both your authorization timeline and long-term success in the federal market.
