NordVPN has launched post-quantum encryption (PQE) support for all its VPN applications. The first iteration of post-quantum cryptography was implemented on the NordVPN Linux application last year. In 2025, NordVPN also rolled out its PQE feature for Windows, macOS, iOS, and Android, including Android TV and tvOS. The PQE upgrade integrates quantum-resistant algorithms into NordLynx, the company’s high-speed VPN protocol based on WireGuard, and complies with NIST’s latest cryptographic standards. In September 2024, NordVPN released a Linux app update with the first post-quantum cryptography upgrade for the Nordlynx protocol — a high-performance VPN protocol known for its extreme speed and security, based on WireGuard. The upgraded protocol complied with the latest National Institute of Standards and Technology (NIST) standards for post-quantum encryption and protected Linux users from quantum decryption, while also collecting essential performance metrics, such as impact on connection speeds and latency. NordVPN’s early Linux deployment allowed the company to collect performance data to optimize encryption transitions without degrading user experience, enabling a seamless rollout across all platforms.
