The paper explains why traditional IT remote-access tools—such as VPN-based solutions—create significant security and operational risks when used in operational technology environments. Extending internet connectivity into lower OT layers expands the attack surface and enables threats like privilege escalation and lateral movement. It highlights challenges including weak access controls, poor credential management, limited visibility into user activity, and difficulties monitoring file transfers, all of which can disrupt operations or introduce malware. A purpose-built platform is presented as a centralized way to enforce granular access, monitor sessions, reduce mean-time-to-repair, and maintain compliance while balancing security with operational continuity.
