- ExpressVPN has lastly applied help for the WireGuard VPN protocol
- Resistance to WireGuard by ExpressVPN resulted within the improvement of its Lightway protocol
- Submit-quantum WireGuard has been added to Home windows, iOS, and Android ExpressVPN apps, with macOS to observe
After over 5 years of refusing to undertake the protocol, going as far as to develop its personal different, ExpressVPN has lastly embraced WireGuard – and it made it quantum-secure.
In a transfer that can influence the whole VPN trade, what TechRadar’s reviewers rated as among the best VPN suppliers available on the market proper now has conceived a future-proofed implementation of the protocol, combining WireGuard with the next-generation encryption algorithm ML-KEM.
That stated, ExpressVPN intends to retain its proprietary protocol Lightway – which already integrates ML-KEM – as its default protocol. However by way of the post-quantum way forward for on-line privateness, its adoption of WireGuard is massively vital.

What’s the WireGuard protocol?
(Picture credit score: WireGuard)
A number of completely different protocols – configurations of guidelines that handle a VPN connection – are at the moment in use. Many suppliers depend on WireGuard, alongside older options like IKEv2/Ipsec, OpenVPN (which is commonly revised), and proprietary options like NordVPN’s NordWhisper and Lightway.
All present protocols have varied strengths and weaknesses, in addition to potential vulnerabilities that haven’t but been uncovered. WireGuard, which ExpressVPN initially evaluated and rejected in 2019, is utilized by many digital non-public community (VPN) providers, and has been touted as a possible answer for Web of Issues and good residence gadget encryption.
ML-KEM, in the meantime, is a quantum-resistant encryption commonplace issued by the Nationwide Institute of Requirements and Expertise (NIST) in late 2024, and extensively welcomed by the cryptography group because the superior response to post-quantum encryption (PQE) wants.
By lastly together with WireGuard in its VPN shopper software program, and integrating ML-KEM, ExpressVPN has provided an answer to the whole VPN trade. It implies that any VPN supplier, large or small, offering it runs its personal servers, can introduce PQE protections.
As ExpressVPN has noticed in a weblog put up: “Submit-quantum protections are virtually non-existent in manufacturing deployments… We’ve solved these gaps and revealed the outcomes. Now it’s on the remainder of the trade to catch up.”
Ranging from August 6, 2025, Submit-quantum WireGuard is out there on ExpressVPN’s iOS, Android, and Home windows apps. Assist for macOS can even observe quickly.
Is quantum computing actually a danger to VPNs?
Quantum computer systems have lengthy been acknowledged as posing a major danger to probably the most stringent present encryption requirements. The underlying math of encryption algorithms which may take millennia to be solved by right now’s machines will be damaged comparatively shortly by quantum computer systems.
This clearly poses a danger to all types of present encryption, not least VPNs. In creating an encrypted route by the web through a VPN server utilizing a VPN app, customers anticipate their knowledge to stay non-public, and protected from statement by ISPs, governments, and unhealthy actors.
Quantum computing disrupts this fully.
Way back to 2020, in its improvement of Lightway, ExpressVPN acknowledged the dangers posed by quantum computing, regardless of its arrival being a decade away. Understanding the maxim of cybercriminals who “harvest now, decrypt later,” they took steps to make sure that Lightway provided PQE safety to customers. So, any knowledge secured with PQE ought to be shielded from decryption by quantum computer systems.
The white paper, “Submit-Quantum WireGuard: A Sensible Implementation Information” by ExpressVPN engineers, Peter Membrey and Timo Beyel, states that whereas their improvement of Lightway solved post-quantum safety, they have been “involved that WireGuard deployments weren’t getting easy options well-suited to VPN suppliers.”
ExpressVPN hasn’t stopped at displaying the remainder of the VPN trade what to do subsequent, both, introducing HTTPS proxy help as an added privateness possibility. That is because of a brand new “strategic partnership” with Bitripple which integrates LT3 acceleration into Lightway, offering improved knowledge transmission for slower web connections.
