- ExpressvPN has finally implemented support for the Wireguard VPN protocol
- Wireguard resistance by ExpressvPN resulted in the development of its Lightway protocol
- A cableguard after quantum to Windows, IOS and Android Expressvpn applications has been added, with macOS to follow
After more than five years of refusing to adopt the protocol, developing its own alternative, Expressvpn has finally adopted Wireguard, and made it quantum safe.
In a movement that will affect the entire VPN industry, which Techradar reviewers described as one of the best VPN suppliers in the market at this time has conceived an implementation of future proof protocol, combining Wireguard with the next-generation encryption algorithm ML-Kem.
That said, Expressvpn intends to retain its owner Lightway protocol, which already integrates ML-Kem, as its default protocol. But in terms of the future after the quanto of online privacy, its adoption of Wireguard is very significant.
What is the cableguard protocol?
Several different protocols, rules configurations that manage a VPN connection are currently in use. Many suppliers trust Wireguard, along with older solutions such as IKEV2/IPSEC, OpenVPN (which is regularly reviewed) and patented solutions such as Nordvpn Nordwhisper and Lightway.
All current protocols have various strengths and weaknesses, as well as potential vulnerabilities that have not yet been discovered. Wireguard, which ExpressvPN initially evaluated and rejected in 2019, is used by many virtual private network services (VPN), and has been promoted as a potential solution for the Internet of things and encryption of intelligent domestic devices.
Meanwhile, ML-KEM is a quantum-resistant encryption standard issued by the National Institute of Standards and Technology (NIST) at the end of 2024, and widely welcome by the cryptography community as the response superior to the needs of post-quantum encryption (PQE).
Finally, it includes Wireguard in its VPN client software and integrating ML-Kem, ExpressvPN has offered a solution to the entire VPN industry. It means that any VPN supplier, large or small, provided it runs its own servers, can introduce PQE protections.
As ExpressvPN has observed in a blog post: “The protections after that quantile are practically non -existent in production deployments … We have solved those gaps and publish the results. It is now in the rest of the industry to catch up.”
As of August 6, 2025, the cableguard after the quantum is available in iOS, Android and Windows Expressvpn applications. The support for macOS will also follow soon.
Is quantum computing a risk for VPN?
Quantum computers have been recognized for a long time that they pose a significant risk for the most strict current encryption standards. The underlying mathematics of encryption algorithms that could take millennia to be resolved through today’s machines can be broken relatively fast by quantum computers.
This clearly raises a risk to all forms of current encryption, no less important for VPN. When creating a route encrypted through the Internet through a VPN server using a VPN application, users expect their data to remain privately except for ISP observation, governments and bad actors.
Quantum computing interrupts this completely.
Already in 2020, in its development of Lightway, ExpressvPN recognized the risks raised by quantum computing, although its arrival was a decade away. Understand the maximum of cybercriminals who “reap now, decipher later”, took measures to ensure that Lightway offered users to use users. Therefore, any insured data with PQE must be protected from deciphered by quantum computers.
The White Paper, “Post-Quantum Wireguard: a practical implementation guide” of Expressvpn, Peter Membrey and Timo Beyel engineers, states that, although their development of the protection of light of light and the protection after the fifth, they were “worried that the implementations of wire protectors were not obtaining very suitable simple solutions for VPN suppliers.”
Expressvpn has not stopped in showing the rest of the VPN industry what to do next, either, introducing Proxy HTTPS support as an additional privacy option. This is thanks to a new “strategic association” with bitripple that integrates the acceleration of LT3 in Lightway, providing an improved data transmission for slower Internet connections.
