ExpressVPN finally supports WireGuard, but adds post-quantum security

• ExpressVPN has finally implemented support for the WireGuard VPN protocol
• Resistance to WireGuard by ExpressVPN resulted in the development of its Lightway protocol
• Post-quantum WireGuard has been added to Windows, iOS, and Android ExpressVPN apps, with macOS to follow

After over five years of refusing to adopt the protocol, going so far as to develop its own alternative, ExpressVPN has finally embraced WireGuard – and it made it quantum-secure.

In a move that will impact the entire VPN industry, what TechRadar’s reviewers rated as one of the best VPN providers on the market right now has conceived a future-proofed implementation of the protocol, combining WireGuard with the next-generation encryption algorithm ML-KEM.

That said, ExpressVPN intends to retain its proprietary protocol Lightway – which already integrates ML-KEM – as its default protocol. But in terms of the post-quantum future of online privacy, its adoption of WireGuard is hugely significant.
