Remote Access and VPN Setup for Managing Systems Off-Site

Facility managers, IT teams and installers often need to reach a site's network remotely — for troubleshooting, monitoring, or configuration changes without a physical visit. Done carelessly (opening ports directly to the internet, for instance), this becomes one of the most common ways sites get compromised, because it's an intentionally created path in.

A VPN (Virtual Private Network) creates an encrypted tunnel that authorised users connect through before they can reach the internal network at all, rather than exposing internal systems directly to the public internet. Combined with proper authentication (ideally multi-factor), this gives remote access without leaving the network broadly exposed.

It's worth confirming whether remote access to your systems goes through a proper VPN or a more exposed method, whether access is logged (so there's a record of who connected and when), and whether former employees' or contractors' access has actually been revoked, not just assumed to be. These are common gaps that only surface during a security review, which is exactly when it's too late.
