Manufacturing Cybersecurity for OT
As IT meets OT and plant attacks rise, protect legacy machines and industrial networks with zero-trust controls. No agents. No disruption.
Last updated:
Protect Legacy CNC & PLC
Agentless protection for equipment that can't be upgraded or patched. Secure the traffic that crosses your shop floor.

Secure Remote Maintenance
OEM vendors connect through a controlled bastion, no open VPN tunnels into your production network.

CMMC & Supply Chain Compliance
Customer audits, IEC 62443, NIS2, and CMMC Level 2 for defense work. One appliance or VM documents the controls without disruption.
Learn moreSecurity for the Factory Floor.
Five capabilities that protect operations and document your controls, one appliance or VM, no production impact.
Legacy Equipment Protection
No agents, no upgrades. Works with CNC machines, PLCs, HMIs, and equipment you've run for decades. Network-level enforcement without touching production systems.
Full Asset Visibility
Automatic discovery across your entire factory network. Know what's connected instantly, IT and OT, managed and unmanaged devices.
Network Segmentation
Replace flat networks with controlled, segmented access. Overlay micro-segmentation without VLAN restructuring or re-cabling.
Secure Vendor Access
On-premise bastion host for OEM vendors and contractors. MFA-enforced, session-scoped, fully logged, no VPN tunnels required.
Compliance & Audit Evidence
Supports IEC 62443, NIS2, customer security audits, and CMMC Level 1 & 2 where you handle defense work. Assessment-ready documentation, without stopping production.
Plug-and-Protect Deployment
Installs inline on your existing network. No architecture change required. Up and running in hours.
No Agents on Production Equipment
Protect CNC machines and PLCs without installing software on operational equipment.
Designed for IT Generalists
Sensible defaults and automated policies. No dedicated security team required to operate.
Access Gate secures your assets first, then exposes the simple services your teams and vendors actually want, so they run through the sanctioned path, not around it.
OT runs through you, not around you.

Common Questions About Manufacturing Security.
Average time from unboxing to full deployment on a manufacturing network.
No. The Access Gate installs inline on your existing network. There is no need to re-cable, re-address, or redesign your infrastructure. It works with your current switches, VLANs, and topology.
Yes. The Access Gate operates at the network level, no software agents are installed on endpoints. It protects CNC machines, PLCs, HMIs, and any device connected to the network, regardless of age or operating system.
The Access Gate supports IEC 62443, NIS2, and general customer security audit requirements, plus CMMC Level 1 & 2 for defense manufacturers. It provides continuous monitoring, access control, and assessment-ready documentation.
The built-in bastion host provides a controlled gateway for OEM vendors and contractors. Each session is authenticated with MFA, scoped to specific resources, and fully logged. No VPN tunnels or open ports required.
No. The Access Gate is designed for organizations without a dedicated security team. It provides sensible defaults, automated policy templates, and a straightforward management interface that IT generalists can operate.
Cybersecurity in manufacturing protects the OT that runs the plant: PLCs, CNC machines, HMIs, SCADA, and the legacy Windows systems behind them. These rarely tolerate agents, patching, or downtime, so Access Gate secures them at the network layer with Zero-Trust access, IT/OT segmentation, and audit-ready evidence for IEC 62443, NIS2, and CMMC, on-premise and without stopping production.
