- NordVPN has moved OpenVPN obfuscation to the NordWhisper protocol
- The move promises faster connections and a wider range of locations
- The change is already in effect on iOS, and the rest of the apps should follow soon.
Staying ahead of network filters is now a constant job for any provider hoping to rank among the best VPN services, and NordVPN just made a change that shows how quickly the situation is changing.
Hidden in the release notes for a new iOS app update, the provider revealed that its obfuscated servers no longer work on OpenVPN. Instead, they are now powered by NordWhisper, the censorship-resistant protocol that NordVPN developed in-house and launched in early 2025.
The reason for this change, according to NordVPN, is simple: better speed and more places to connect from.
Marijus Briedis, CTO at NordVPN, also told TechRadar that NordWhisper is designed to work as well, if not better, than OpenVPN in overcoming restrictive networks. “In many cases, users should see improvements through better speeds and a wider range of available server locations,” he added.
The update is rolling out gradually, so not all users will see it immediately. Vriedis confirms that while the change is already in effect on the iOS VPN app, the team plans to roll it out to Android, Windows, and macOS in the coming weeks.
What has really changed and why it matters
Obfuscated servers are a specialized category designed to hide the fact that you are using a VPN, letting your traffic escape firewalls and deep packet inspection on networks that would otherwise block it. For years, connecting to it meant switching your protocol to OpenVPN, because obfuscation was tied to the TCP and UDP variants of OpenVPN.
This is the part that NordVPN has reworked. The obfuscated server category is now operating under NordWhisper’s hood, and it’s just the latest step in a busy period for the provider.
The biggest advantage for users is speed. Obfuscated OpenVPN connections cause additional overhead because VPN traffic is wrapped in an additional layer of obfuscation, which tends to reduce performance. NordWhisper was designed from the ground up to blend in with normal web traffic, so moving the obfuscation there should alleviate that penalty and provide a smoother connection.
The second advantage is range. NordVPN’s pool of obfuscated servers has always been limited to a modest list of countries, much smaller than its full fleet. Moving obfuscation to NordWhisper opens the door to a wider set of locations, which is exactly what censored and heavily filtered users need most.
Above all, none of this comes at the expense of security. NordWhisper follows the same encryption and privacy standards as NordVPN’s other protocols, so users benefit from stealth without giving up anything in terms of protection.
How does NordWhisper work?
NordWhisper is NordVPN’s proprietary, censorship-resistant protocol, first launched in January 2025 in response to the growing sophistication of network filtering around the world.
NordWhisper uses web tunneling technology to disguise VPN traffic as ordinary Internet activity, making it much more difficult to filter and block filters and deep packet inspection.
The protocol is best suited to networks that actively block VPNs, such as certain workplaces, schools, public Wi-Fi, and heavily censored regions. On open, unrestricted networks, faster options like NordLynx remain the best choice for everyday use.
NordVPN also indicated where it wants to take the technology next, evolving NordWhisper to a fully TLS-based design and exploring the QUIC protocol to stay ahead of increasingly capable censorship tools. This is a direction the company sees as the “future” of VPN protocols.
