CMMC Compliance for On-Premise.
CMMC requires access control, audit logging, and network segmentation. Most tools assume cloud-connected IT. Access Gate enforces CMMC controls on-premise, across IT and OT, without agents or downtime.
What is CMMC on-premise compliance?
CMMC (Cybersecurity Maturity Model Certification) is a DoD framework that requires defense contractors to meet specific cybersecurity controls before handling CUI. On-premise compliance means enforcing these controls directly on your local network, covering legacy equipment, OT systems, and air-gapped environments that cloud tools cannot reach.

Access Gate supports CMMC Level 2 controls across AC, AU, IA, SC, and SI families on existing on-premise networks.
Yes. Access Gate runs entirely on-premise. Policy enforcement, audit logging, and session recording all happen locally. No data leaves your network. This supports air-gapped, hybrid, and classified environments.
Access Gate covers controls in Access Control (AC), Audit and Accountability (AU), Identification and Authentication (IA), System and Communications Protection (SC), and System and Information Integrity (SI). A full control mapping is available in the CMMC compliance solution page.
Access Gate enforces controls at the network layer. It does not install software on endpoints. Legacy CNC machines, PLCs, HMIs, and other OT equipment are protected through overlay networking and proxy-based access control without modification.
An enduring exception applies to OT assets that cannot meet standard CMMC requirements due to operational constraints. These assets require documented compensating controls. The enduring exception resource page covers the specific requirements and what auditors expect.
Millbrook Machine achieved CMMC Level 1 in 4 days. Elna Magnetics secured 100% of CUI flows for Level 2 targeting. Typical deployments take hours for installation and one to two weeks for full policy configuration and compliance documentation.
Yes. Access Gate connects to your existing network infrastructure. It adds identity-based access control and microsegmentation as an overlay. Existing firewalls, switches, and VLANs remain in place and continue operating.
