What is manufacturing cybersecurity?
Manufacturing cybersecurity protects the machines that run production, such as PLCs, CNC machines, robots and HMIs, and the network that connects them. It keeps production running by controlling who reaches each machine, vendors included, and by recording every connection for audits.
For the full method, read the OT cybersecurity guide. Defense suppliers should also read CMMC compliance for manufacturers.

Protect your oldest machines.
CNC machines and PLCs that can't be patched stay protected. Nothing to install on them.

Give vendors safe remote access.
OEM vendors connect through the gate. Their VPN or 4G link ends there, with no route into production.

Audit-ready for your customers.
Every connection is logged for your audits.
Learn moreOne gate per plant. Four jobs.
Access Gate connects to your existing network. Production keeps running.
See every machine.
Find every machine on the plant network, old or new, IT and OT.
Control who reaches what.
Each person reaches only the machines they need. No VLAN changes, no re-cabling.
Reach any machine, securely.
Vendors log in with MFA. Each session reaches only the machines it needs and is logged.
Prove every audit.
Every connection is logged. Export the evidence your customers ask for.

Up in a day per plant.
Access Gate connects to your existing network. No architecture change.
Nothing to install on machines.
CNC machines and PLCs stay as they are. Access Gate works from the network.
Run by your IT team.
Sensible defaults and ready-made policies. No dedicated security team needed.
Which cyber risks matter most in a plant?
Four risks with public figures behind them, and what Access Gate does about each.
| Risk | The figure | What Access Gate does |
|---|---|---|
| Ransomware reaches the plant | Manufacturing was more than two-thirds of the 3,300 industrial organizations hit by ransomware in 2025 (Dragos, 2026). | Machines sit in zones that only the gate can reach. An infected office PC has no path to a machine it has no rule for. |
| Attackers stay unseen | Ransomware stayed in OT for 42 days on average in 2025, against 5 days at sites with full OT visibility (Dragos, 2026). | Lists every machine and logs every connection, so an unexpected session shows up the day it starts. |
| Machines that cannot be patched | 26% of 2025 ICS advisories had no patch or mitigation from the vendor (Dragos, 2026). | Puts a gate in front of the machine. Nothing is installed on it, and its configuration does not change. |
| The cost of a breach | The global average cost of a data breach is USD 4.99 million (IBM Cost of a Data Breach Report 2026). | Limits what one stolen password can reach, and records each session for the investigation. |
The gate is the first service you run, not the last.
Secure your plants today. Control your digitalization tomorrow.
Access Gate puts compute on the wire, next to your assets. Once the gate is in, the same box hosts the services that pull OT in securely: remote access, protocol gateways, DNS and time, historian, update server. Accelerate your digitalization, in control.
Trusted by manufacturers across the supply chain.
of sensitive data flows, from engineering designs to production plans, stay on your own network.

Common questions about manufacturing security.
From unboxing to a working Access Gate on a manufacturing network.
No. The Access Gate connects to your existing network rather than cutting into it. It uses overlay micro-segmentation, so there is no need to re-cable, re-address, or redesign your infrastructure. It works with your current switches, VLAN, and topology.
Yes. The Access Gate is agentless: it operates at the network level, and 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, NIST SP 800-82, 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. It works with your existing VPN or 4G link and requires no open ports.
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, NIST SP 800-82, and CMMC, on-premise and without stopping production.
