The rise of remote access technologies has revolutionized how industries monitor and manage critical infrastructure. From energy grids to manufacturing plants, remote work has become indispensable, offering benefits like increased efficiency and reduced downtime. However, as industrial environments rely more on remote access, the need for robust cybersecurity measures grows. Without proper protections, these connections can expose critical systems to cyber threats.

Flat networks and minimal network segmentation—common in industrial settings—make it easier for attackers to move laterally once inside. Adding to the complexity, many vendors maintain VPN connections for device monitoring and maintenance. While convenient, these connections can become vulnerable entry points if not properly secured. This highlights the importance of adopting secure remote access practices and strengthening VPN implementations in industrial environments.

This guide will explore:

1. What a VPN is and its role in industrial remote access.
2. Common vulnerabilities in VPNs and their associated risks.
3. The importance of network segmentation for limiting lateral movement.
4. Best practices for securing VPNs in industrial environments.
5. Steps to deploy a secure VPN solution tailored to remote maintenance needs.

As remote work and maintenance continue to grow, securing industrial networks with robust VPN solutions and effective network segmentation is essential to staying ahead of cyber threats. Explore how to safeguard your infrastructure with this essential guide to industrial cybersecurity.
