Secure enclaves for sensitive workloads
Confine the sensitive work to a defined environment and only that environment has to meet the strictest standard, and only that environment gets assessed.
A secure enclave is an isolated environment within an organization’s systems where sensitive workloads and data are processed under stricter controls than the rest of the estate: its own segment, identity and access rules, device requirements, monitoring and controlled flows in and out. Its purpose is scope: regulated data such as CUI or protected health information stays inside, so the enclave meets the regulation and is assessed, while the rest of the business runs under ordinary controls. For government contractors it is often the single decision that makes CMMC Level 2 achievable; for others it is how a small team handles sensitive matters without re-engineering the whole organization.
In detail
What the evidence shows.
Why scope is the problem
If sensitive data can be anywhere, every system and every user is in scope for the strictest requirements and for the assessment that tests them. Most organizations cannot bring the whole estate to that standard. Confining the data to an enclave reduces the problem to one they can solve.
What an enclave consists of
A network segment or dedicated cloud environment. Identity and access specific to the enclave with phishing-resistant MFA. Managed devices meeting a defined posture, or virtual desktops so no data reaches the endpoint. Monitoring and logging at the enclave boundary. Documented, controlled flows for how data enters and leaves. A list of who may be inside and why.
Keeping data inside
The enclave fails when data leaks out by habit: an email attachment, a download, a copy to a personal drive. Controls at the boundary and training for the people inside address this, and the data flow analysis that precedes the design finds the paths that already exist. Periodic discovery confirms the data has not spread.
Documenting it
The boundary, the controls and the flows are documented so that an assessor can see what is in scope and why the rest is not. See secure enclave design for sensitive workloads, CMMC Level 2: the controls that catch contractors out and the glossary entry for secure enclave.
