When you’re jet-setting or just enjoying a local coffee shop, a Virtual Private Network (VPN) is more than a luxury – it’s a necessity. Especially during travel season, the best VPNs are crucial for safeguarding your digital life, encrypting your traffic, masking your IP address, and minimizing the risk of data exposure on public Wi-Fi networks.
At ZDNET, we believe in providing recommendations you can trust. Our advice stems from countless hours of independent testing, in-depth research, and meticulous comparison shopping.

The undisputed champion metric for any VPN, especially for travelers, is speed – specifically, download speeds. Whether you’re streaming your favorite shows, downloading important attachments, or simply browsing the web, a fast VPN ensures your online activities remain seamless and secure, even when you’re far from home.
Behind the Scenes: ZDNET’s Rigorous VPN Speed Tests
To pinpoint the fastest VPN for globetrotters, we subjected the top five VPNs to exhaustive testing in our state-of-the-art lab in Kentucky. Our methodology was designed for precision and consistency: we utilized distinct Raspberry Pi configurations, each running a unique VPN service and protocol, connected to a reliable Spectrum cable connection.
These devices executed scheduled test cycles every 16 minutes, strategically staggered to prevent network congestion and inter-device interference. Each single test iteration meticulously captured four crucial metrics: download speed, upload speed, ping/latency, and packet loss. This scientific approach ensures stable, isolated, and highly accurate measurements.
Our comprehensive testing spanned 24 hours for each setup, generating 90 data points per Raspberry Pi, per metric, daily. Over a full six-day cycle, involving six combinations of protocols and server locations, we amassed approximately **2,160 data points per VPN service**. This massive dataset provided a robust foundation for our analysis.
The testing framework included OpenVPN as a baseline for comparison, alongside each VPN’s preferred protocol. We evaluated performance against three diverse server locations to simulate various travel scenarios: US New York (close), UK London (medium distance), and Tokyo, Japan (far distance).
To accurately assess speed, we focused on the **median download speeds** rather than the average. As Gianmarco Chumbe, our product testing lab manager, explains, the median is more representative, effectively filtering out temporary spikes, dips, or other outlier events common in internet performance. Higher median download speeds generally indicate superior throughput performance.
Our primary focus was on the preferred protocol for each VPN, as these are engineered to yield the best results. We also paid close attention to server speeds in non-US locations, reflecting the timely needs of summer travelers. This detailed approach allowed us to identify the VPNs that genuinely excel when you’re on the move.
And the Winner Is… NordVPN: Unparalleled Speed for Travelers
After sifting through thousands of data points, one VPN consistently soared above the rest in terms of speed, earning it a prestigious **ZDNET Lab Awards badge**: **NordVPN**. Its performance, particularly when utilizing its proprietary NordLynx protocol, was exceptional across all test conditions.
We observed a striking difference in NordVPN’s performance between OpenVPN and NordLynx. Mr. Chumbe noted that “NordLynx consistently performed among the strongest options, particularly for long-distance server connections, where it achieved some of the highest download speeds observed during testing.” This means NordVPN with NordLynx offers robust speed, even when connecting to servers half a world away.
While NordVPN dominated, other VPNs also showed strong capabilities in our preferred protocol testing. **Surfshark**, for instance, tied with NordVPN for the fastest download speed in our Tokyo location tests and even led in some US-based comparisons. Similarly, **IPVanish** delivered promising speeds across all locations when operating on the WireGuard protocol.

It’s important to note that not all preferred protocols performed equally. ExpressVPN, for example, exhibited some of the slower download speeds on its Lightway-UDP protocol during these specific tests. This doesn’t inherently mean ExpressVPN is a slow VPN; rather, it suggests that other protocols, such as OpenVPN, might offer better performance in certain scenarios.
Smart VPN Use: Tips for Your Next Adventure
Before committing to a VPN service for your travels, remember that almost all providers offer a free trial or a money-back guarantee, typically ranging from 7 to 30 days. This allows you to test the VPN’s performance with your devices and common travel destinations before making a full commitment. You can sign up, use it for your trip, and cancel upon your return if it doesn’t meet your long-term needs.
While a VPN is a powerful tool for securing your data in transit, it’s not an impenetrable shield for your device itself. If your computer or phone is physically seized, law enforcement might still be able to access your data, even if it was encrypted during transmission. Remember that online services in other countries may also offer less protection than those in your home country.
It’s a common misconception that all VPNs drastically slow down your internet speed. While the encryption and decryption process can introduce a slight delay, a good travel VPN will have a minimal impact. The added layer of security, especially on vulnerable public hotspots, far outweighs any minor speed reduction. Keep in mind that slow public Wi-Fi or hotel connections are often the source of slow speeds, not necessarily the VPN itself.
Finally, choose a VPN that provides reliable customer support. Like any subscription software, you might encounter issues with installation, usage, renewals, or cancellations. Access to a responsive support team ensures you can resolve problems quickly, keeping your connection secure and your travels smooth.
