How It Works
SMC sits between your network and your machines. Nothing changes on the floor — everything changes for the assessor.
What a transfer looks like
SMC creates a technical boundary between your IT network and your CNC controllers. This architecture supports a narrower, more defensible assessment boundary.
G-code moves from CAM to machine through SMC — encrypted, authenticated, and logged. RS-232, Ethernet, or native protocol. No USB drives.
Every transfer gets a forensic record — who sent it, which machine received it, when it ran, and a cryptographic hash for integrity reference.
SMC generates a compliance report for every transfer — tagged to NIST 800-171 controls. Your assessor gets the evidence package without you building it by hand.
Before and after
The assessor doesn't evaluate your CNC controllers. They evaluate SMC — a purpose-built compliance boundary that handles the controls your machines can't.
Every machine that touches CUI is in CMMC scope
Assessor asks for patching, antivirus, access controls on each controller
No audit trail for file transfers
USB drives create uncontrolled data paths
Machines behind SMC are out of direct assessment scope
Assessor evaluates one controlled boundary, not every machine
Complete forensic audit trail for every transfer
No USB drives — encrypted, authenticated transfers only
Compliance mapping
SMC generates evidence mapped directly to NIST 800-171 control families. Your assessor sees the controls satisfied, not a stack of spreadsheets.
Authenticated operators. Role-based access. No anonymous file transfers.
Immutable transfer logs with timestamps, operator identity, file hashes, and destination machine.
Controlled baseline. File integrity verification. No unauthorized modifications.
Every operator authenticates before transferring files. No shared logins.
Encrypted transfers replace uncontrolled USB media. Automatic purge after delivery.
Encrypted channel between network and controller. Data at rest and in transit is protected.
