Is TeamViewer Secure for Remote HMI Access? NIST-Compliant Alternatives for Industrial Procurement

For procurement specialists and plant managers sourcing industrial software, enabling remote access to Human-Machine Interfaces (HMIs) is a critical operational need. The common use of consumer-grade tools like TeamViewer raises significant security and compliance concerns for industrial environments. This article provides a risk assessment and a practical procurement framework for secure, NIST-aligned alternatives.

Assessing the Risks of TeamViewer for Industrial HMI Access
While convenient, TeamViewer and similar general-purpose remote desktop tools present inherent risks for Operational Technology (OT). They are designed for IT environments, often lacking granular access controls for specific HMIs or PLCs. Their architecture typically requires outbound internet connections to third-party servers, expanding the attack surface. From a compliance perspective, they may not meet the stringent requirements of the NIST Cybersecurity Framework, particularly in the Protect and Detect functions, nor satisfy industry-specific standards often required by global clients.

Procurement Checklist for NIST-Compliant Remote Access Solutions
When sourcing a replacement, align your supplier evaluation with the NIST Core Functions:
• Identify: Does the solution provide a complete asset inventory of accessible HMIs and user session logging?
• Protect: Does it enforce role-based access control (RBAC), multi-factor authentication (MFA), and end-to-end encryption? Is it a true "zero-trust" network architecture?
• Detect: Does it offer real-time monitoring and alerts for unauthorized access attempts?
• Respond & Recover: Can access be revoked immediately, and are session audits available for forensic analysis?
Prioritize vendors whose solutions are purpose-built for industrial control systems (ICS) and can provide documented compliance evidence.

Sourcing and Implementing Secure Alternatives
Leading alternatives include dedicated industrial remote access gateways and secure conduit software. When selecting a supplier, verify their experience in your sector (e.g., manufacturing, energy). During equipment procurement, mandate that new machinery supports secure remote maintenance protocols. In logistics and deployment, plan for phased implementation, starting with non-critical systems. Crucially, factor in the total cost of ownership, including training for maintenance teams and integration with existing security operations centers (SOCs). A rigorous supplier selection process that prioritizes security architecture over mere functionality is essential for long-term risk mitigation and supply chain resilience.
