FedRAMP Impact Levels: Low vs Moderate vs High
FedRAMP uses three impact levels derived from FIPS 199 and NIST SP 800-60 to categorize federal information systems. The impact level determines which control baseline applies, the scope of 3PAO assessment, and your ongoing continuous monitoring obligations. Updated 26 March 2026.

Controls
Up to 125 controls
Timeline
9-12 months
Typical Data Types
- Publicly available information
- Administrative data with no PII
- General government business functions
- Non-sensitive collaboration tools
Example Use Cases
- Public-facing informational websites

Control Family Comparison
Selected control families showing how requirements escalate from Low to High impact. Higher impact levels add both more controls and more stringent parameter values within each control.
| Control Family | Low | Moderate | High |
|---|---|---|---|
| Access Control (AC) | 15 | 25 | 31 |
| Audit and Accountability (AU) | 9 | 16 | 16 |
| Configuration Management (CM) | 6 | 13 | 14 |
| Identification and Authentication (IA) | 8 | 12 | 13 |
| Incident Response (IR) | 6 | 10 | 10 |
| Risk Assessment (RA) | 5 | 6 | 9 |
| System and Communications Protection (SC) | 20 | 39 | 44 |
| System and Information Integrity (SI) | 12 | 17 | 20 |
