This article takes a deep dive into configuring NordVPN on pfSense

Frequently Asked Questions on Setting up and Using NordVPN on Pfsense

Will using NordVPN on Pfsense make me completely anonymous online?

No, there is nothing that can make you completely anonymous online, except you isolate your computer and not connect to the internet. While you cannot achieve a hundred percent anonymity, NordVPN has privacy features that can give you a high level of anonymity, such as Double VPN, Tor over VPN, and a watertight zero-log policy.

Furthermore, almost all free VPN services have limitations on speed, bandwidth, server network, etc. Using NordVPN on Pfsense is way better than using the best free VPN service. 

Will using NordVPN on Pfsense protect me against malware?

It depends on the sophistication of malware. NordVPN can never be an alternative to an anti-malware application. The best NordVPN can do is protect you from basic network threats that look to infiltrate your network or ads that contain malware. Its CyberSec feature blocks unwanted ads and known malicious sites.
