Remote work has shifted the attack surface
Before 2020, most work traffic ran through the company network. That meant managed firewalls, network segmentation, and central monitoring. Mass remote work moved the connection onto the employee's home WiFi. It runs on consumer-grade routers, the ISP boxes that are rarely audited. They share the network with weak IoT devices like IP cameras, smart bulbs, old gaming consoles, and Android TVs. The problem is now well documented. A hacked personal device on the same LAN as the work machine is a recurring entry point named in cybersecurity reviews from ENISA and national CERTs. Still, no single percentage is reliable, since methods differ.
The VPN does not remove all those risks, but it does two useful things. It encrypts traffic leaving the work device for the internet, so a LAN attacker sees encrypted noise instead of usable packets. It also hides your real IP from third-party services. That helps limit the cross-service tracking run by ad-tech networks and data brokers.
Two VPN solutions for two distinct perimeters
Business VPN - mandated by IT
B2B solutions are not rivals to NordVPN; they answer a different need. They include NordLayer, Perimeter 81, Twingate, Tailscale Business, Cloudflare Zero Trust, Cisco AnyConnect, and Palo Alto GlobalProtect. They let IT:
- Grant fine-grained access to internal apps like the intranet, ERP, and files, without opening the whole network to the internet.
- Require strong authentication, SSO plus 2FA, on every session.
- Log who connects to what, when, and from which IP.
- Revoke a departing employee's access at once.
You don't choose this VPN. It comes with a client to install, sometimes as a system-level agent. It turns on by itself when you reach company resources and stays out of the way for personal traffic.
Consumer VPN - under your control
For your personal connection, and for freelance work if it applies, a serious consumer VPN covers most needs:
- NordVPN - audited by Cure53 and Deloitte, with 6,200+ servers across 110+ countries. It uses the NordLynx protocol, a custom WireGuard build, plus a system kill switch, and the price is fair on a 2-year plan.
- ProtonVPN - based in Switzerland, with open-source apps and clear cryptography. The free plan is usable, limited to 3 countries, with no bandwidth cap.
- Mullvad - anonymous payment by cash or crypto, and no account to create; you just get a generated account number. It runs yearly public audits, but its server network is thinner for streaming.
Shared criteria for work use: a system kill switch turned on, DNS leak protection, the WireGuard protocol, and public audits < 24 months old.
Practical 5-minute setup
- Install the desktop client on the personal device.
- Go to Settings → Kill Switch and turn on Internet mode (system), not the per-app mode.
- Turn on DNS leak protection. It is usually ON by default at NordVPN, but confirm it.
- Pick a server in your country or a neighbouring one, with latency under 30 ms for smooth video calls.
- Test on vpn-leak-test-2026 and confirm your IP, DNS, and WebRTC do not leak outside the tunnel.
If you also run the work VPN on the same machine, turn off the personal VPN during work sessions. Or use split-tunnelling to keep work network traffic out of the personal VPN. Otherwise you stack two tunnels, which slows latency and may set off IT alerts.
Compliance side note
If you are an employer or IT lead, name two points clearly in the remote-work charter. First, the monitoring scope of the work VPN: only traffic to the company network, or all device traffic? Regulators in most countries require you to tell employees this plainly. Second, the rule on a coexisting personal VPN. You can ban it under the law, but that is hard to enforce; allowing it via split-tunnelling is usually the practical path.
Many freelancers now bill clients covered by GDPR, which is near-universal in the EU and growing in the US and Canada through state laws. Being able to document a personal encryption policy, with a VPN, disk encryption, and a password manager, makes sub-contractor audits easier. IT and consulting contracts ask for these audits more and more. If you are comparing providers for your remote-work setup, our best NordVPN alternatives comparison covers ProtonVPN and Mullvad. They fit some work profiles better, thanks to anonymous payment and unlimited devices.
