Secure Remote
Access For OT
Remote access to industrial systems is inevitable—but most solutions were designed for IT, not OT. CyInfra removes the security risk and operational complexity from remote access to your industrial environment, giving the right people access to the right systems, at the right time—nothing more.
Remote Access Is the #1 Exploited Attack Vector in OT
Remote access to operational technology environments has become unavoidable—third-party vendors, remote engineers, and distributed operations teams all require connectivity to industrial systems. But remote access is also the single most commonly exploited attack vector in OT incidents. Every unsecured connection is an open door into your critical infrastructure.
IT remote access tools—standard VPNs, RDP, and remote desktop solutions—were not designed for OT environments. They lack the granular access controls, session monitoring, and OT-specific security architecture that industrial environments require. Giving a third-party vendor VPN access to your OT network is equivalent to handing them the keys to your entire facility.
OT and IT networks have fundamentally different security priorities. IT focuses on data confidentiality; OT demands absolute availability and zero tolerance for downtime. Remote access solutions designed for IT can impose security controls that destabilize sensitive OT processes. Secure OT remote access requires purpose-built architecture that respects the operational constraints of industrial environments.
What OT Secure Remote Access should do
Zero Trust Access Controls
Eliminate the implicit trust of traditional VPNs. Authenticate every user, validate every device, and enforce least-privilege access to specific OT assets—with time-limited sessions and granular controls for both internal users and third-party vendors.
Full Session Recording & Audit
Record every remote session in full, with live monitoring capability and immediate disconnect authority for your security team. Maintain a complete audit trail that satisfies IEC 62443 compliance requirements and supports forensic investigations.
Simplified Access for Third Parties
Remove the complexity of VPN configuration and IP management for vendor engineers and external support teams. Purpose-built OT remote access provides secure connectivity without requiring technical setup knowledge from non-security staff.
Secure Remote Access Features Designed for Industrial Environments
IEC 62443-Aligned Architecture
Deploy remote access architecture that meets ISA/IEC 62443 security level requirements, with proper zone segmentation, encrypted tunnels, and access controls that satisfy industrial security standards.
Multi-Factor Authentication
Enforce MFA for all remote sessions—internal and third-party—ensuring that stolen credentials alone cannot grant access to your industrial systems.
Granular, Time-Limited Access Windows
Grant access only to the specific assets a user needs, only for the duration required. Customizable access windows for vendor maintenance sessions prevent unauthorized activity outside scheduled maintenance periods.
Purpose-Built OT User Experience
Deliver a seamless, friction-free remote access experience that doesn't require OT engineers to understand VPN configuration or network routing. Reduce Mean Time to Repair (MTTR) by making secure connectivity fast and straightforward.
