How to Secure OT Remote Access Without VPN Risk

Operational technology remote access security is becoming critical as plant engineers, IT teams, and third-party vendors increasingly require access to OT environments without exposing organizations to unnecessary cyber risk.

In this video, we explain how BeyondTrust Privileged Remote Access (PRA) helps organizations secure remote access into OT environments while maintaining visibility, control, and operational continuity.

Traditional remote access approaches like VPNs, unmanaged vendor tools, and shared credentials often create excessive risk inside operational technology networks. These methods can introduce uncontrolled access pathways, reduce visibility into remote activity, and make it difficult to audit who accessed critical systems and why.

BeyondTrust PRA provides OT teams with a secure, standardized approach to privileged remote access using session-based controls and least privilege principles. Instead of broad network access, users only gain access to the systems they are specifically authorized to reach.

What You’ll Learn:

→ Why OT remote access creates cybersecurity risk
→ The dangers of VPN-based access in OT environments
→ How BeyondTrust PRA secures vendor and third-party access
→ Why least privilege is critical for operational technology security
→ How PRA improves visibility and auditability across remote sessions

Operational technology environments were originally designed for uptime and safety — not today’s highly connected remote access requirements. As more organizations modernize industrial operations and support remote maintenance workflows, secure access controls become essential to reducing attack surface and preventing unauthorized access.

FREQUENTLY ASKED QUESTIONS:

Q: What is OT remote access?
A: OT remote access allows engineers, vendors, and IT teams to securely connect to operational technology systems for maintenance, monitoring, and support.

Q: Why are VPNs risky in OT environments?
A: VPNs often provide broad network access, increasing attack surface and making it difficult to enforce granular security controls.

Q: What is BeyondTrust Privileged Remote Access?
A: BeyondTrust PRA is a secure remote access solution that enables controlled, audited, least-privileged access to critical systems.

Q: How does PRA improve OT security?
A: PRA provides session-based access controls, visibility into remote activity, auditing capabilities, and secure vendor access management.

Q: What is least privilege access?
A: Least privilege ensures users only receive access to the systems and resources necessary for their role or task.

Q: Why is vendor access management important in OT?
A: Third-party vendor access can introduce major security risks if not properly controlled, monitored, and audited.

Q: Who should use BeyondTrust PRA?
A: Industrial organizations, manufacturers, utilities, critical infrastructure operators, and OT security teams benefit from secure privileged remote access solutions.
