FedRAMP Readiness Services & Authorization Guide
Pre-Assessment Preparation & 3PAO Readiness Support
FedRAMP Services, The Basics
Core Definition
The Federal Risk and Authorization Management Program (FedRAMP) is a U.S. government-wide security authorization framework for cloud service offerings (CSOs) used by federal agencies. Administered by the General Services Administration (GSA), FedRAMP enables cloud service providers (CSPs) to undergo a standardized security assessment, conducted by an accredited Third-Party Assessment Organization (3PAO), that federal agencies can then reuse under a "do once, use many times" model, rather than each agency repeating the full assessment.
FedRAMP is built on NIST SP 800-53 Rev 5 security controls, applied at one of three impact levels — Low, Moderate, or High — based on FIPS 199 categorization of the data being processed, stored, or transmitted. Each level draws a progressively larger set of controls from the NIST catalog: approximately 156 at Low, 323 at Moderate, and 410 at High (per the current FedRAMP Security Controls Template; exact counts vary by control enhancement).
Once authorized, a CSP's security package is listed in the FedRAMP Marketplace, allowing federal agencies to leverage the existing assessment rather than repeating it.
FedRAMP also offers FedRAMP 20x, an automation-first authorization path that replaces narrative documentation with machine-readable evidence and continuous validation through Key Security Indicators (KSIs). Rev 5 and 20x are two distinct paths a CSP chooses between, not a wholesale replacement: 20x suits cloud-native, well-scoped services, while Rev 5 remains the path for larger, more complex, or High-impact systems.
Wide-scale availability of 20x for the lower classes is targeted for the second half of 2026; higher-impact (Class D / High) availability is expected later, into FY27.
A note on 2026 changes: FedRAMP is consolidating its rules under the Consolidated Rules for 2026 (CR26), finalized mid-2026 to provide a stable rulebook through 2028. Three shifts matter for any CSP planning authorization now: the program is moving to a single "FedRAMP Certified" designation (replacing the older "FedRAMP Authorized" language); the familiar Low / Moderate / High impact labels are being restructured into lettered Certification Classes (Class C maps to today's Moderate, where most CSPs land); and machine-readable authorization packages are becoming mandatory on a phased schedule. Existing authorizations carry over without re-authorization. RSI Security builds readiness against these changes, not around them.
Getting FedRAMP authorized starts with getting FedRAMP ready. RSI Security helps cloud service providers build the security posture, documentation, and control implementation required to enter and succeed in the formal 3PAO assessment process.
What Problems FedRAMP Solves
FedRAMP addresses systemic inefficiencies and security risks in how federal agencies evaluate and adopt cloud services. Core problems it solves:
- Duplicated, agency-by-agency cloud security assessments that created inconsistent standards and wasted resources
- No standardized security baseline for cloud vendors serving the federal government
- Slow federal cloud adoption due to the absence of a reusable, government-wide authorization mechanism
- Inadequate or inconsistent protection of federal data in cloud-hosted environments
- Lack of standardized continuous monitoring requirements for cloud providers serving government clients
- Poor visibility into third-party cloud supply chains supporting federal programs and defense contractors
When Organizations Need FedRAMP Authorization
Organizations need FedRAMP authorization, and FedRAMP readiness services, when specific contractual or operational conditions are met:
- If your cloud service offering stores, processes, or transmits federal information on behalf of a U.S. government agency
- If you are a SaaS, IaaS, or PaaS provider seeking to sell to federal agencies or appear in the FedRAMP Marketplace
- If you support defense contractors or other regulated entities whose systems require FedRAMP-authorized components
- If you are required to demonstrate NIST SP 800-53 control alignment as part of a federal procurement or solicitation requirement
- If your current authorization needs to be upgraded to a higher impact level due to evolving contract scope
- If you are a subcontractor or technology partner whose infrastructure sits within the authorization boundary of a prime contractor's FedRAMP-scoped system
Why FedRAMP Readiness Matters, Before You Engage a 3PAO
FedRAMP authorization is not a self-assessment. It requires an independent evaluation by an accredited 3PAO, and organizations either pass or enter remediation cycles that can extend timelines by months and significantly increase costs.
In the program's entire history, fewer than roughly 500 cloud services have achieved FedRAMP authorization — a small number relative to the broader cloud market, reflecting how demanding the authorization bar is. The organizations that move through assessment efficiently are the ones that arrive prepared.
FedRAMP has no official, government-issued cost estimates; the figures below reflect industry consensus and vary widely by impact level, boundary size, and starting maturity. Total authorization costs commonly run from several hundred thousand dollars to a few million upfront (Moderate typically in the mid-six to low-seven figures; High higher), plus substantial annual continuous-monitoring costs. Readiness preparation is the most controllable cost variable — organizations that invest in proper gap assessment and SSP development before engaging a 3PAO avoid the expensive remediation cycles that drive most authorization overruns.
That preparation is what RSI Security delivers.
RSI helps CSPs define their authorization boundary, assess control gaps against the applicable NIST 800-53 baseline, build audit-grade documentation (SSP, POA&M), implement required security controls, and validate readiness before a 3PAO assessment begins. The goal: minimize findings, reduce remediation cycles, and protect your authorization timeline and budget.
What's Included in FedRAMP Readiness Services
Assessment Phase — Gap Analysis & Impact Level Determination
The Assessment Phase establishes the organization's current cloud security posture and maps it against the applicable FedRAMP impact level baseline. This phase typically includes:
- Impact level determination — Low (including the tailored LI-SaaS baseline for low-risk SaaS), Moderate, or High, based on FIPS 199 data categorization
- Authorization boundary definition and data flow analysis
- Gap analysis against NIST SP 800-53 Rev 5 controls at the applicable baseline
- Review of existing cloud architecture, policies, procedures, and documentation
- Evaluation of inherited controls from underlying cloud infrastructure providers (e.g., AWS, Azure, GCP)
- Identification of third-party services within the authorization boundary that may require their own FedRAMP status
Outcome: A clear authorization gap profile, confirmed impact level, and a readiness score that defines the path forward.
Implementation Phase — Control Build-Out & SSP Development
The Implementation Phase closes identified gaps and aligns the cloud environment and documentation with FedRAMP requirements. This phase typically includes:
- System Security Plan (SSP) development — the core FedRAMP authorization document, typically 200–400+ pages
- Remediation guidance for missing or partially implemented NIST SP 800-53 controls
- Development of supporting security policies and procedures
- POA&M (Plan of Action and Milestones) development for tracked open findings
- Technical and administrative control implementation support
- Continuous monitoring program design aligned to FedRAMP ConMon requirements
- FIPS 140 encryption validation guidance and MFA implementation verification
Outcome: A control-compliant cloud environment with a complete, 3PAO-ready SSP and documentation package.
Validation Phase — Pre-3PAO Readiness Testing
The Validation Phase confirms that implemented controls are functioning as intended and that documentation can withstand independent assessment scrutiny before a 3PAO engages. This phase typically includes:
- Internal control validation and pre-assessment readiness testing
- Evidence collection aligned to 3PAO testing methodologies
- Security Assessment Plan (SAP) review and alignment support
- Vulnerability scanning readiness verification
- Review of third-party service FedRAMP authorization status within the boundary
- Authorization boundary diagram and data flow diagram review
- Identification of residual gaps prior to 3PAO engagement
Outcome: A validated, assessment-ready security posture with evidence packages that reduce 3PAO finding risk.
Note: RSI Security delivers readiness services through this phase. Formal 3PAO assessment, including Security Assessment Report (SAR) production and Authority to Operate (ATO) issuance, is performed by an accredited, independent Third-Party Assessment Organization. RSI can support 3PAO selection and coordinate handoff.
Reporting & 3PAO Handoff Package
The final phase consolidates all readiness outputs into a structured package that positions the organization for 3PAO engagement and ATO submission. This phase typically includes:
- Complete FedRAMP readiness report with gap closure status
- Final SSP, POA&M, and supporting documentation review
- Authorization package structure: SSP, SAP template, evidence repository
- 3PAO selection guidance and engagement coordination support
- Continuous monitoring program operational readiness review
Outcome: A submission-ready FedRAMP documentation package and clear operational path into formal 3PAO assessment.
How FedRAMP Readiness Services Work
FedRAMP readiness follows a structured lifecycle designed to assess cloud security posture, implement required controls, build audit-grade documentation, and prepare the organization to succeed in formal 3PAO assessment.
Scoping & Impact Level Determination
Define the authorization boundary — the specific systems, services, data flows, and components that will be included in scope. Determine the applicable impact level (Low, Moderate, or High) using FIPS 199 data categorization. This decision drives control count, documentation depth, cost, and timeline for everything that follows.
Gap Assessment
Evaluate the current cloud environment against the applicable NIST SP 800-53 Rev 5 control baseline. Identify missing, partial, or non-compliant controls. Map inherited controls from the underlying infrastructure provider. Produce a detailed compliance gap profile that drives the remediation roadmap.
Remediation Planning
Build a prioritized, risk-based remediation roadmap tied to specific NIST SP 800-53 control families. Develop or update the POA&M to track open findings. Define timelines, resource requirements, and implementation ownership across technical and administrative domains.
Implementation Support
Provide guidance and support in implementing required controls across the cloud environment. This includes SSP development, policy and procedure creation, system configuration alignment, access control hardening, encryption validation, and continuous monitoring program design.
Pre-3PAO Validation
Validate that all implemented controls are functioning as intended and that evidence packages meet 3PAO testing standards. Conduct internal readiness simulations, review vulnerability scanning outputs, verify authorization boundary accuracy, and confirm documentation completeness before 3PAO engagement begins.
3PAO Handoff & Readiness Package Delivery
Deliver the complete readiness package — SSP, POA&M, SAP framework, evidence repository — and support 3PAO selection and engagement. RSI Security does not perform the formal 3PAO assessment; we prepare you to pass it.
Types of FedRAMP Readiness Services
FedRAMP readiness support is delivered through multiple service tiers depending on an organization's current security maturity, authorization timeline, and internal resource capacity.
FedRAMP Readiness Assessment (Gap Analysis)
A readiness assessment is designed for organizations beginning their FedRAMP journey who need a baseline understanding of where they stand against applicable impact level requirements. This service typically includes:
- Impact level determination and authorization boundary scoping
- High-level gap analysis against applicable NIST SP 800-53 controls
- Review of existing cloud architecture and documentation
- Identification of major compliance deficiencies and risk areas
- Preliminary readiness scoring and authorization roadmap
Best for: organizations that are unsure of their FedRAMP standing, evaluating authorization feasibility, or preparing for a federal contract that will require FedRAMP authorization.
Full FedRAMP Readiness Program (End-to-End Pre-Assessment Support)
A full readiness program provides comprehensive support across the complete pre-assessment lifecycle, from initial scoping through 3PAO handoff. This service typically includes:
- Detailed gap assessment against applicable NIST SP 800-53 Rev 5 baseline
- Full SSP development and documentation build-out
- Remediation planning and implementation support
- POA&M development and ongoing tracking
- Continuous monitoring program design
- Pre-3PAO validation and evidence package preparation

Best for: organizations actively pursuing FedRAMP authorization and seeking a structured, expert-led path to 3PAO readiness.
Continuous Monitoring (ConMon) Readiness & Ongoing Advisory
Continuous monitoring support helps organizations maintain their FedRAMP-aligned security posture after authorization and meet ongoing ConMon obligations required to retain ATO status. This service typically includes:
- Monthly vulnerability scanning and reporting support
- Ongoing POA&M tracking and remediation coordination
- Quarterly control validation reviews
- Annual assessment readiness maintenance
- Alignment support as FedRAMP requirements evolve (Rev 5, FedRAMP 20x)
- Documentation and evidence tracking for continuous compliance
Best for: organizations with existing FedRAMP authorization that need ongoing support to maintain readiness and meet ConMon deliverable requirements.
Advisory / Consulting-Only Services
Advisory services provide strategic FedRAMP guidance without full implementation support, supporting internal teams in designing and executing their own readiness programs. This service typically includes:
- Strategic authorization planning and roadmap development
- Expert guidance on impact level selection and boundary scoping
- Control mapping and NIST SP 800-53 interpretation support
- Internal team enablement on SSP development and evidence collection
- Review of client-developed documentation and implementation plans
- FedRAMP 20x pathway evaluation and preparation guidance
Best for: organizations with internal security teams that need expert direction rather than full-service execution.
Who Needs FedRAMP Readiness Services?
FedRAMP authorization requirements apply primarily to cloud service providers that store, process, or transmit federal data, and to any organization whose cloud infrastructure supports government clients, defense contractors, or regulated federal programs.
| Industry | Why FedRAMP Applies | Typical Use Case | Related Compliance Context |
|---|---|---|---|
| SaaS Companies | SaaS platforms used by government agencies or defense contractors must be FedRAMP authorized if federal data flows through them | Secure cloud infrastructure for government clients, federal procurement eligibility | CMMC, SOC 2, NIST 800-171 |
| Defense Contractors | Defense supply chain systems increasingly incorporate cloud components subject to FedRAMP requirements | DoD-adjacent cloud platforms, CUI-handling SaaS, defense program infrastructure | CMMC, NIST 800-171, DFARS 7012 |
| Healthcare Providers | Federal health programs (VA, CMS, HHS) require FedRAMP-authorized cloud services for patient data and federal health infrastructure | Federal EHR systems, government health IT, CMS-connected platforms | HIPAA, FedRAMP Moderate |
| Financial Services | Federal financial agencies and Treasury-adjacent programs require authorized cloud services for data security and compliance | Federal financial data processing, government financial systems | GLBA, FISMA, NIST 800-53 |

Frameworks Supported & Compliance Alignment
FedRAMP readiness services align closely with multiple cybersecurity and regulatory frameworks that share overlapping control requirements, assessment methodologies, and security expectations.
| Framework | Relationship to FedRAMP | How It Connects | Why It Matters |
|---|---|---|---|
| NIST SP 800-53 Rev 5 | Foundational control framework | FedRAMP control baselines are derived directly from NIST 800-53; all impact levels map to this standard (approximately 156 / 323 / 410 controls at Low / Moderate / High) | Defines every security control required for FedRAMP authorization |
| CMMC 2.0 | Adjacent defense compliance framework | CMMC Level 2 and FedRAMP Moderate share significant control overlap; organizations pursuing both benefit from unified readiness programs. Note: DoW suspended the CMMC Phase II certification mandate in July 2026; DFARS 252.204-7012 and self-assessment obligations remain in effect. | Defense contractors often need both; parallel implementation reduces duplication |
| SOC 2 Type II | Commercial audit framework | Overlaps with FedRAMP in access control, monitoring, availability, and confidentiality controls | SOC 2-compliant organizations have a stronger baseline for FedRAMP readiness |
| ISO 27001 | Global security management standard | Shares risk management, policy, and governance foundations with FedRAMP | ISO 27001-certified organizations often have documentation and ISMS foundations that accelerate FedRAMP SSP development |
| FedRAMP 20x | Modernized authorization pathway | Replaces static SSP documentation with automated, machine-readable Key Security Indicators (KSIs) and continuous monitoring | Wide-scale availability for the lower classes is targeted for H2 2026; Rev 5 and 20x are separate, non-transferable paths — evaluate which fits your architecture now |

How FedRAMP Maps to NIST SP 800-53
FedRAMP control baselines are derived directly from NIST SP 800-53 Rev 5, with FedRAMP-specific parameters and overlays. Every control an organization implements for FedRAMP is a NIST 800-53 control.
The impact level determines which subset applies: approximately 156 controls at Low, 323 at Moderate, and 410 at High, per the current FedRAMP Security Controls Template. FedRAMP adds the verification layer on top — it mandates independent 3PAO validation of those controls rather than allowing self-attestation.
How FedRAMP Relates to CMMC 2.0
CMMC and FedRAMP serve different regulatory purposes but share significant control overlap, particularly at CMMC Level 2 (NIST SP 800-171 aligned) and FedRAMP Moderate (NIST SP 800-53 aligned). Defense contractors operating cloud environments may fall under both programs, and organizations with a strong NIST 800-171 control baseline often have a meaningful head start on FedRAMP implementation.
Key distinction: CMMC governs the defense supply chain and CUI protection; FedRAMP governs cloud services used by federal agencies. Both can apply to the same organization.
Note on CMMC status: On July 13, 2026, the Department of War suspended the CMMC Phase II third-party certification mandate pending a 60-day program review. The underlying obligation is unchanged — DFARS 252.204-7012 still binds, NIST SP 800-171 Rev. 2 remains the standard, and Phase 1 self-assessment requirements remain in effect. The control overlap that makes a unified readiness approach efficient is unaffected by the suspension.
How FedRAMP Relates to SOC 2 Type II
SOC 2 and FedRAMP serve different regulatory audiences but share overlapping security objectives, particularly around access control enforcement, system monitoring and logging, confidentiality and data protection, and risk management processes.
SOC 2-compliant organizations typically have a stronger documentation baseline and policy maturity that supports FedRAMP SSP development. However, FedRAMP requires significantly more prescriptive control implementation, boundary documentation, and government-specific security measures that go beyond SOC 2 scope.
FedRAMP 20x: What It Means for Your Authorization Strategy
FedRAMP 20x replaces narrative-based SSP documentation with continuous, machine-readable compliance demonstrated through Key Security Indicators (KSIs), with evidence packages expressed in machine-readable (OSCAL) format. Rather than writing hundreds of pages explaining how controls are met, organizations design systems that produce evidence of secure configurations in near real-time.
The path has rolled out in stages: a completed Low pilot, a Moderate pilot that ran through early 2026, and wide-scale availability for the lower classes targeted for the second half of 2026. High-impact (Class D) availability is expected later, into FY27. Because Rev 5 and 20x are separate, non-transferable paths, work toward one does not transfer to the other — organizations pursuing authorization now should decide their path early. RSI Security can advise on both.
Benefits of FedRAMP Readiness Services
Reduced Assessment Risk
Arriving at a 3PAO assessment unprepared is the most common and expensive FedRAMP mistake. Incomplete SSPs, undefined authorization boundaries, insufficient vulnerability scanning, and missing evidence artifacts all generate findings that push timelines by months and drive up remediation costs.
RSI Security's readiness program systematically eliminates these failure points before assessment begins, reducing the probability of findings, remediation cycles, and delayed ATO issuance.
Faster Authorization Timelines
Traditional FedRAMP authorization timelines run 12–18 months under Rev 5. Organizations that enter 3PAO assessment with a complete, validated SSP, clean POA&M, and evidence packages in order can compress that significantly.
By addressing gaps early and building documentation correctly the first time, RSI Security reduces the back-and-forth between CSP and 3PAO that extends most authorization engagements.
Improved Cloud Security Posture
FedRAMP readiness enforces consistent implementation of NIST SP 800-53 controls across the cloud environment — technical, administrative, and operational. The result is not just a compliance artifact; it's a materially stronger security posture with reduced attack surface, improved access controls, and formalized continuous monitoring that benefits the organization beyond the authorization process.
Federal Market Access & Revenue Enablement
FedRAMP authorization is a hard gate to the federal cloud market. Without it, CSPs cannot sell to federal agencies or appear in the FedRAMP Marketplace. With it, a single authorized offering can be leveraged across every federal agency, significantly expanding the addressable market without repeating the assessment process.
Readiness is the prerequisite. Getting it right the first time protects both the investment and the timeline to revenue.
Common Challenges We Solve
Undefined or Inaccurate Authorization Boundaries
The authorization boundary — defining exactly what systems, data flows, and services are in scope — is the foundation of the entire FedRAMP SSP. Organizations frequently misconfigure this, either scoping too broadly (creating unnecessary control burden) or too narrowly (leaving federal data paths unprotected and unreviewed).
According to FedRAMP's own documentation, inaccurate boundary definition and insufficient data flow diagrams are among the most cited barriers to successful authorization.
Impact: Leads to 3PAO findings, significant SSP rework, and authorization delays.
Incomplete or Low-Quality SSP Documentation
The System Security Plan is the single most important document in the FedRAMP authorization package, and the most common failure point. A poorly written, incomplete, or inconsistent SSP is explicitly cited by FedRAMP's program office as a primary barrier to authorization success.
Many organizations have security controls implemented but lack the technical writing depth and security expertise to document them at the level 3PAOs require. FedRAMP's own guidance states: if you don't have a strong technical writer with security experience, hire one.
Impact: Authorization delays, remediation cycles, and failed 3PAO reviews that could have been prevented with proper documentation preparation.
Control Implementation Gaps
A common issue is partial or inconsistent implementation of required NIST SP 800-53 controls across systems within the authorization boundary. This is especially prevalent with FIPS 140 encryption validation, multi-factor authentication implementation, vulnerability scanning coverage, and management of external services that handle federal data.
If any third-party service within the boundary is not FedRAMP authorized at the correct impact level, it must be removed, absorbed, or replaced — a significant remediation task if caught during 3PAO assessment rather than during readiness preparation.
Impact: Creates compliance inconsistencies that result in 3PAO findings, remediation cycles, and timeline extension.
Misunderstood Impact Level or Scoping Decisions
Selecting the wrong impact level, or misclassifying the data types the system handles, leads to either over-building security controls unnecessarily or under-building and failing assessment. Moving from Low to Moderate or Moderate to High after initial authorization is treated as a significant change, effectively requiring a new authorization effort.
Many organizations also fail to account for inherited controls from their infrastructure provider, either re-documenting work that's already done or failing to properly reference inherited control documentation.
Impact: Wasted remediation effort, misaligned implementation, and significant cost and timeline risk if discovered late.
Continuous Monitoring Program Immaturity
FedRAMP authorization is not a one-time event. ConMon obligations include monthly vulnerability scans, quarterly reviews, and annual assessments. Organizations that achieve ATO without a functional continuous monitoring program quickly fall out of compliance, putting their authorization at risk.
Building ConMon into the readiness program, not bolting it on afterward, is essential for sustained authorization.
Impact: Loss of ATO status, agency dissatisfaction, and re-authorization burden if ConMon obligations are not operationalized at go-live.

Frequently Asked Questions About FedRAMP Readiness Services
What is FedRAMP authorization used for?
FedRAMP authorization is required for cloud service providers that want to offer their services to U.S. federal agencies. It standardizes cloud security assessment across the government so that a CSP undergoes a single rigorous evaluation, conducted by an accredited 3PAO, that can then be reused by any federal agency to issue an Authority to Operate (ATO), rather than repeating the full assessment process for each agency separately.
What is the difference between FedRAMP readiness and FedRAMP authorization?
FedRAMP readiness refers to the preparation work required before formal 3PAO assessment begins, including gap analysis, SSP development, control implementation, and evidence collection. FedRAMP authorization is the formal outcome: an ATO issued by a federal agency after a successful 3PAO assessment.
RSI Security delivers FedRAMP readiness services. The formal assessment and ATO issuance is performed by an accredited Third-Party Assessment Organization (3PAO). We prepare you to pass that assessment.
How long does FedRAMP authorization take?
Under FedRAMP 20x, some early Low-pilot authorizations were completed in a matter of months rather than the traditional year-plus, though timelines depend heavily on architecture, scope, and how cloud-native the system is.
The readiness phase, where RSI Security operates, typically runs 3–9 months depending on starting maturity, impact level, and resource capacity.
How much does FedRAMP authorization cost?
FedRAMP has no official, government-issued cost estimates; the figures below reflect industry consensus and vary widely by impact level, boundary size, and starting maturity. Total authorization costs commonly run from several hundred thousand dollars to a few million upfront (Moderate typically in the mid-six to low-seven figures; High higher), plus substantial annual continuous-monitoring costs.
Readiness preparation is the most controllable cost variable — organizations that invest in proper gap assessment and SSP development before engaging a 3PAO avoid the expensive remediation cycles that drive most authorization overruns.
What is a 3PAO and do I need one?
A Third-Party Assessment Organization (3PAO) is an independent, FedRAMP-accredited firm that conducts the formal security assessment of a cloud service offering. A 3PAO engagement is required for all FedRAMP Moderate and High authorizations, and for most Low authorizations under the Rev 5 pathway.
RSI Security is not a 3PAO. We are a readiness partner — we prepare your security posture, documentation, and evidence packages to meet 3PAO standards before that formal assessment begins.
What is a System Security Plan (SSP) and why does it matter?
The System Security Plan is the primary document in a FedRAMP authorization package. It describes the cloud service offering's security architecture, authorization boundary, data flows, and control implementation across every applicable NIST SP 800-53 control. SSPs for Moderate systems are typically 200–400+ pages.
A poorly written, incomplete, or inconsistent SSP is the single most cited cause of FedRAMP authorization delays and 3PAO remediation findings. Getting the SSP right, before 3PAO engagement, is the most impactful thing an organization can do to protect its authorization timeline.
What is FedRAMP 20x and should I pursue it?
FedRAMP 20x is a modernized authorization pathway that replaces static SSP documentation with automated, machine-readable security evidence produced by the cloud system itself. It is designed to dramatically compress authorization timelines and is targeted at cloud-native organizations that can build continuous monitoring directly into their infrastructure.
Wide-scale availability of 20x for the lower classes is targeted for the second half of 2026, with higher-impact (Class D / High) availability expected later, into FY27. Rev 5 and 20x are separate paths — work toward one does not transfer to the other. Whether 20x or Rev 5 is right depends on your architecture, timeline, and federal customer requirements. RSI Security can advise on both.
What industries are required to pursue FedRAMP authorization?
FedRAMP authorization is required for any cloud service offering that stores, processes, or transmits federal information on behalf of a U.S. government agency. This includes SaaS, IaaS, and PaaS providers serving federal agencies directly, as well as cloud platforms used by defense contractors, federal health programs, financial agencies, and AI/data infrastructure providers supporting government workloads.
Can we get FedRAMP ready without outside help?
Some organizations attempt readiness internally, particularly those with existing security programs, NIST 800-171 or SOC 2 compliance foundations, or prior government contracting experience. However, FedRAMP's SSP requirements, boundary documentation standards, and evidence expectations are highly specific, and gaps identified during 3PAO assessment are far more expensive to remediate than gaps caught during internal preparation.
External readiness support is most valuable for organizations without prior federal compliance experience, those pursuing Moderate or High impact authorizations, and any organization with aggressive authorization timelines.
Get Started with FedRAMP Readiness Services
Organizations pursuing FedRAMP authorization begin with an initial scoping conversation to determine impact level, current security maturity, authorization boundary complexity, and appropriate readiness timeline. RSI Security helps define the right starting point, whether that's a targeted readiness assessment, a full pre-authorization program, or advisory support for an internal team.
Start with a FedRAMP Readiness Consultation
Speak with a cloud security compliance expert to understand your applicable FedRAMP impact level, current readiness gaps, and what a realistic path to 3PAO-ready looks like for your organization.
Best for: organizations unsure what impact level applies, whether FedRAMP is required for their contracts, or where to begin.
Contact RSI Security for Full Readiness Program Support
For organizations ready to move into full SSP development, control implementation, and pre-assessment validation, RSI Security delivers end-to-end FedRAMP readiness support through every phase prior to 3PAO engagement.
Best for: organizations with active federal contracts, pending government solicitations, or defined authorization timelines.
