Tech Talk: OT Remote Access: VPN-less, Controlled, Secure

In IT, a breach means data loss. In OT, it can mean equipment damage, downtime, or threats to human safety. The same access controls that protect enterprise IT often fall short on the plant floor and applying them incorrectly can cause the very disruptions they are meant to prevent.

In this 30-minute tech talk, BeyondTrust Inside Solutions Engineer Rob Molinaro shows how Privileged Remote Access secures connectivity across the Purdue Model, from the enterprise layer down to the process level. He walks through how VPN-less access, credential injection, and full session audit control let vendors and technicians connect to OT systems without exposing passwords or widening the network, while giving security teams visibility into every privileged session.

Key Takeaways:

• Why traditional VPNs and IT access controls fall short in OT environments
• How PRA maps privileged access to the Purdue Model, from enterprise layers to the process floor
• Giving vendors and technicians VPN-less access without exposing the broader network
• Using credential injections, passwords are never seen, shared, or stored by the user
• Establishing audit control over every privileged OT session: who connected, what they did, and when
