How Much Does FedRAMP Cost? (Ready, Moderate, High)

Primary Cost Drivers

• 3PAO assessment — initial testing, annual reassessment, significant-change testing
• Documentation — SSP, policies, diagrams, evidence indexes, OSCAL/package prep
• Engineering remediation — logging, segmentation, FIPS crypto, identity, backup/DR gaps
• ConMon tooling — vulnerability management, SIEM (e.g. ThreatHawk), ticketing, reporting
• Advisory / programme management — readiness, sponsor coordination, package quality

Why Baseline Changes Cost

Rev 5 control volume scales as Low 156, Moderate 323, High 410. Higher baselines usually mean more narrative depth, deeper testing, and more ongoing ConMon effort — not a linear price list.

How Teams Reduce Spend (Without Cutting Corners)

• Freeze the authorization boundary early
• Reuse mature SOC 2 / ISO evidence with deliberate remapping
• Automate AU and scan evidence before 3PAO fieldwork
• Avoid parallel “shadow” tools that duplicate ConMon reporting

How CyberSilo Helps

• Evidence workflows for SSP, POA&M, and control status via Compliance Standards Automation
• ThreatHawk SIEM for AU-family logging, ConMon telemetry, and investigation evidence
• Advisory scoping for readiness, baseline selection, and agency-path planning — contact CyberSilo

Frequently Asked Questions

Why won’t you publish a dollar range?

Published ranges are frequently invented or stale. Drivers and complexity dominate; we scope after boundary and readiness review.

Is Ready much cheaper than Moderate?

Ready is a different milestone, not a full Moderate ATO. Compare scope honestly with your 3PAO and sponsor path.

What about 20x costs?

Expect investment in machine-readable evidence and automation. Treat transition work as an additional programme track through June 11, 2027.
