Common Budgeting Mistakes
Under-budgeting remediation
The 3PAO almost always finds more issues than your internal gap analysis. Budget 10-20% of your total authorization cost as remediation contingency. Organizations that skip this line item regularly exceed their budget by $100k-$300k.
Forgetting ConMon in year 1
Year-one ConMon starts immediately after ATO. Monthly vulnerability scanning, POA&M management, and incident response readiness begin on day one. Budget ConMon costs from the authorization date, not from year two.
Not accounting for staff time
FedRAMP consumes significant internal engineering and compliance time. For a 50-person engineering team, expect 2-4 FTE equivalents diverted for 12-18 months. This is a real cost even if no new hires are made.
Ignoring tooling costs
SIEM licensing, vulnerability scanning, EDR, encryption key management, and log aggregation add $65k-$300k/year for Moderate impact. These are not optional. They are required to meet FedRAMP control baselines.
Treating authorization as a one-time cost
FedRAMP is an ongoing financial commitment. ConMon costs are perpetual. A $1M Moderate authorization becomes $2.5M-$4M over five years. Present the 5-year TCO to your CFO, not just the authorization cost.
Not budgeting for boundary expansion
Adding services or regions to your authorization boundary after ATO triggers Significant Change Requests. Each major boundary expansion can cost $50k-$200k. Budget for at least one expansion in the first two years.
