What does the term Corporate VPN mean in Cyber Essentials?

A corporate VPN is a virtual private network that connects back to your office location, or to a virtual or cloud firewall, and that you administer so the firewall controls apply.

NCSC wording · Section B

A corporate VPN is a virtual private network that connects back to your office location, or to a virtual or cloud firewall. You must administer the VPN so that you can apply the firewall controls.

How does Corporate VPN apply to Cyber Essentials?

In plain terms

A corporate VPN is a private tunnel from a laptop back to your own office or cloud firewall. Once connected, the laptop's internet traffic passes through a firewall your organisation controls, so the firewall rules you set apply even when the person is working from home.

What Cyber Essentials asks

The definition, quoted above, is from section B of the requirements. It matters for remote workers. The home and remote working section says home routers you did not supply are out of scope, "which means you need to apply Cyber Essentials firewall controls (such as a software firewall) on user devices." It then adds: "If the home/remote worker is using a corporate VPN, their internet boundary is on the company firewall or virtual/cloud firewall."

In the question set, A2.4.2 asks how home and remote workers connect, giving "corporate VPN" as one example. A4.1.1 still asks for software firewalls on all computers, laptops and servers, enabled "at all times".

Does your VPN count?

Common mistakes

  • Switching off the laptop firewall because the VPN is on. A4.1.1 and the requirement for software firewalls on "untrusted networks, such as public wifi hotspots" still apply.
  • Exposing the VPN login page without MFA or brute-force protection. It is an internet-facing service under A5.4 to A5.7, and its firmware or software falls under the 14-day rule.
