🕵️♀️ Choosing Enclave vs Enterprise
Which one should you choose?
Enclave | Enterprise | |
Your CUI is handled inside a bounded subset of the organization (e.g., a tenant, VPC/VNet, or segmented set of systems) that has its own policies, controls, and boundary. | ✅ | ⛔️ |
Typical for small businesses using Microsoft (GCC/GCCH) or AWS workspaces dedicated to CUI. | ✅ | ⛔️ |
Select Enclave when the CUI environment is separate from the rest of IT, and you can point to an SSP specific to that enclave. | ✅ | ⛔️ |
CUI is processed across the entire corporate environment under one security program/boundary. | ⛔️ | ✅ |
You maintain organization‑wide controls that meet CMMC L1 for all in‑scope systems. | ⛔️ | ✅ |
Select Enterprise only if your SSP covers the entire company network and all relevant endpoints. | ⛔️ | ✅ |
Tip: If you’re unsure, you are likely an Enclave, especially if your CUI lives in a dedicated cloud tenant with restricted users, with separate identity, logging, and data controls from the rest of the business.
👨💼 Attestation Official (who should sign?)
- CISO, CIO, or CEO; whoever is accountable for the security of the attested environment.
- They are affirming that all CMMC L1 practices are implemented and maintained. Ensure they have reviewed the SSP and any implementation evidence.
🔁 After submission
- The Level 1 self‑assessment becomes visible in SPRS under your cage code.
- Keep your SSP and evidence current; update the attestation if your scope, controls, or ownership change.
