When we test VPN providers, we test them a number of times on a 1Gbps line to see what they can really do. Second only to privacy, having a fast VPN is essential – and this is where the modern protocols really start demonstrating OpenVPN’s weaknesses. Unlike WireGuard, though, there are no patches needed for Lightway to be used safely – great news for any budding developers looking to create their own VPN. It’s also open-source, and has been fully audited by Cure53. Much like WireGuard, Lightway has been built from the ground up using wolfSSL, which means its code is cleaner and easier to understand than OpenVPN’s. We’ve explored in-depth whether we consider WireGuard safe to use if you’re interested.įinally, we come to Lightway. However, with a couple of tweaks this inherent issue can be remedied, and providers like NordVPN, IVPN and Surfshark all offer WireGuard or WireGuard-based protocols combined with a fix that stops IPs being stored. Vanilla WireGuard stores IP addresses on the server and does not delete them, which poses a problem for VPNs that claim to be zero-logging. However, it was not designed with privacy as a priority. Rather than being based on old, iterated code, WireGuard was developed just a few years ago to be fast, lightweight and secure. OpenVPN uses OpenSSL, the most widely-used SSL library, and the protocol’s open-source nature means there are no hidden nasties. OpenVPN has been trusted for almost two decades, and despite a somewhat bloated and ageing codebase it’s still solid and safe to use. Predictably, all three of the most popular protocols are safe to use and offer good privacy – but there are times when one might be favorable over another. Privacy #įirst and foremost, a VPN protocol has to keep you and your information safe. Here, we’ll compare what we consider the three most important protocols – OpenVPN, WireGuard and Lightway – to see which is best suited for particular purposes, and whether the protocols a provider offers should impact your buying decision. However, other options like ExpressVPN’s in-house (but open-source) Lightway are also in use. Of the new protocols, WireGuard is the most widely used and has been adopted by just about every VPN worth its salt. However, in recent years we’ve seen a number of alternatives crop up, and now almost every one of the best VPN providers offers a modern alternative – be that based on open-source tech or developed in-house.
