NordVPN moves obfuscated servers from OpenVPN to in-house NordWhisper protocol

NordVPN moved obfuscation from OpenVPN to the NordWhisper protocol

The move promises faster connections and a wider range of locations

The change is already live on iOS, with the rest of the apps set to follow soon

Keeping ahead of network filters is now a permanent job for any provider hoping to rank among the best VPN services, and NordVPN has just made a change that shows how quickly the ground is shifting.

Tucked away in the release notes of a fresh iOS app update , the provider has revealed that its obfuscated servers no longer run on OpenVPN. Instead, they are now powered by NordWhisper , the censorship-resistant protocol NordVPN built in-house and launched at the start of 2025.

The reason for the 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 just as well, if not better than OpenVPN for overcoming restrictive networks. "In many cases, users should see improvements thanks to better speeds and a wider range of available server locations," he added.

The update is rolling out gradually, so not every user will see it straight away. Vriedis confirms that while the change is already live on the iOS VPN app, the team plans to roll it out to Android, Windows, and macOS within the following weeks.

What has actually changed, and why it matters

(Image credit: Nord Security) Obfuscated servers are a specialty category designed to hide the fact that you are using a VPN at all, letting your traffic slip past firewalls and deep packet inspection on networks that would otherwise block it. For years, connecting to them meant switching your protocol to OpenVPN , since obfuscation was tied to OpenVPN's TCP and UDP variants.

That is the part NordVPN has reworked. The obfuscated server category now runs on NordWhisper under the hood, and this is only the newest step in a busy stretch for the provider .

The biggest benefit for users is speed. Obfuscated OpenVPN connections carry extra overhead because the VPN traffic is wrapped in an additional disguising layer, which tends to drag performance down. NordWhisper was designed from the ground up to blend in with normal web traffic, so shifting obfuscation onto it should ease that penalty and deliver a smoother connection.

The second benefit is reach. NordVPN's obfuscated server pool has historically been limited to a modest list of countries, far smaller than its full fleet. Moving obfuscation onto NordWhisper opens the door to a broader set of locations, which is exactly what censored and heavily filtered users need most.

Crucially, none of this comes at the expense of security. NordWhisper follows the same encryption and privacy standards as NordVPN's other protocols, so users get the stealth without giving anything up in terms of protection.

How does NordWhisper work?

NordWhisper is NordVPN's proprietary, censorship-resistant protocol, first launched in January 2025 as a response to the growing sophistication of network filtering around the world.

NordWhisper uses web tunnel technology to disguise VPN traffic as ordinary internet activity, which makes it far harder for filters and deep packet inspection to single out and block.

The protocol is best suited to 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 remain the better everyday pick.

NordVPN has also signalled 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 is a direction the company frames as " the future" of VPN protocols .
