- NordVPN moved OpenVPN obfuscation to the NordWhisper protocol
- The move promises faster connections and a wider range of locations.
- The change is now available on iOS, and the rest of the apps will follow soon.
Staying on the cutting edge of network filters is now a constant job for any provider that wants to be among the best VPN services, and NordVPN just made a change that shows how quickly the terrain is changing.
Hidden in the release notes of a new iOS app update, the provider revealed that its obfuscated servers are no longer running on OpenVPN. Instead, they now run NordWhisper, the censorship-resistant protocol that NordVPN built in-house and launched in early 2025.
The reason for the change, according to NordVPN, is simple: better speed and more places to connect from.
Marijus Briedis, CTO of NordVPN, also told TechRadar that NordWhisper is designed to perform just 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 right away. Vriedis confirms that while the change is now available in 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, allowing your traffic to escape firewalls and deep packet inspection on networks that would otherwise block it. For years, connecting to them meant changing their protocol to OpenVPN, as obfuscation was tied to the TCP and UDP variants of OpenVPN.
That’s the part that NordVPN has redesigned. The obfuscated server category now runs on NordWhisper under the hood, and this is just the newest step in a very busy stretch for the provider.
The biggest benefit for users is speed. Obfuscated OpenVPN connections carry additional overhead because the VPN traffic is wrapped in an additional disguised layer, which tends to reduce performance. NordWhisper was designed from the ground up to integrate with normal web traffic, so changing the obfuscation to it should alleviate that penalty and offer a smoother connection.
The second benefit is reach. Historically, NordVPN’s pool of obfuscated servers has been limited to a modest list of countries, much smaller than its entire fleet. Moving obfuscation to NordWhisper opens the door to a broader set of locations, which is exactly what heavily filtered and censored users need most.
Most importantly, none of this comes at the expense of security. NordWhisper follows the same encryption and privacy standards as the other NordVPN protocols, so users gain 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 increasing sophistication of network filtering around the world.
NordWhisper uses web tunneling technology to disguise VPN traffic as normal Internet activity, making it much more difficult for filters and deep packet inspection to identify and block.
The protocol is best suited for networks that actively block VPNs, such as some workplaces, schools, public Wi-Fi, and heavily censored regions. On open, unrestricted networks, faster options like NordLynx are still the best option for everyday use.
NordVPN has also signaled where it wants to take the technology next, moving NordWhisper toward a fully TLS-based design and exploring the QUIC protocol to stay ahead of increasingly capable censorship tools. It’s a direction the company frames as “the future” of VPN protocols.
