- 01Moderate vs High is the most consequential architectural decision a CSP entering federal makes. The control delta is substantial, audit costs grow materially, and operating a High system in production demands serious engineering investment.
- 02Choose Moderate when: civilian customers handling moderate-impact data, CUI but not classified or highly sensitive, first-time federal entry needing defensible time-to-revenue.
- 03Choose High when: DoD mission systems, data whose loss would be catastrophic, or contracts that explicitly require High. Anything else is overbuild.
- 04The optimal path is Moderate now, High later: architect for High-readiness from day one (FIPS 140-3 crypto, GovCloud-equivalent regions, US-citizen admin) but certify Moderate first to capture revenue while completing the additional High control work over 18 months.
Choosing the FedRAMP impact level is the single most consequential architectural decision for a CSP entering the federal market. The control delta between Moderate and High is substantial, the audit cost grows materially, and the engineering investment to operate a High system in production is significant.
When Moderate is the right answer
- 01Your target customers are civilian agencies handling moderate-impact data
- 02Your service handles CUI but not classified or highly sensitive information
- 03You are entering federal for the first time and need a defensible time-to-revenue
When High is the right answer
Department of Defense customers handling high-impact mission systems, services that handle data whose loss of confidentiality, integrity, or availability would have a catastrophic effect, and any case where your contracts list explicitly require it.
The path: Moderate today, High later
Architect for High-readiness from the start (FIPS 140-3 validated crypto, full GovCloud-equivalent regions, US-citizen administrative access) but certify Moderate first. Most successful CSPs follow this path, capturing Moderate-eligible revenue while completing the additional High control work over 18 months.
