Industrial Revolution 4.0 has fundamentally changed how manufacturing systems are managed. Highly-specialized operational technology (OT) is now being joined up with Industrial Internet of Things (IIoT) devices. This allows technicians to access and remotely manage real-time machine data to spot part failures at an early stage and maintain overall equipment effectiveness (OEE). In some situations, it makes sense to manage data security via a remote desktop virtual private network (VPN) connection. Increasingly, however, industrial enterprises are turning to more versatile cloud-based remote access VPNs. Cloud-based VPNs can provide system engineers with secure, flexible remote access to many hundreds of machines in the field, managed from a single, central control point.
