VPN Meaning: What Does a VPN Do & How VPNs Work
A virtual private network also hides the data it’s sending and receiving using encryption. Unlike corporate virtual private networks, personal virtual private networks don’t provide access to private networks. Business VPNs provide secure access to corporate networks and resources. Attila covers software, apps and services, with a focus on virtual private networks. RAM-only servers run on volatile memory and are wiped of data when they are rebooted or shut down.
Secure the data you send and receive
- This is particularly important for organizations and their corporate networks.
- With the right tools, a curious entity such as a stalker, hacker, or online troll can find your general geographical location through your IP address.
- VPN stands for “Virtual Private Network” and describes the opportunity to establish a protected network connection when using public networks.
- VPN encryption is the process of using data encryption (encryption protocols) to create a secure tunnel for your data to travel through.
- You can now surf the internet at will, as the VPN protects all your personal data.
- NordVPN is an exceptional VPN that’s extremely fast, great for streaming and packed with privacy features.
Sometimes, firewalls or security software can disrupt VPN connections. It has strong security protections and is often bundled with the IPSec protocol, which authenticates and encrypts packets of data sent over the VPN. Some protocols help improve speed, while others help improve data privacy and security. VPN protocols decide how data is routed between your computer and the VPN server. For example, if your business uses Chromebooks, you can search for tutorials specifically for these devices. If you don’t, search for other providers’ setup guides that use the same devices.
Help & Support
Extensions make it easier for users to quickly switch and configure their VPN while surfing the internet. You can now surf the internet at will, as the VPN protects all your personal data. For this reason, it is crucial that you choose a trusted VPN provider to ensure both the concealment of your internet activities and ensure the highest level of security. While your ISP cannot see your internet traffic, your VPN provider can. Once the malware has found its way onto your device, it can steal or damage your data, whether you are running a VPN or not. While they protect your IP and encrypt your internet history, a VPN connection does not protect your computer from outside intrusion.
Although its VPN is only available on four platforms — Mac, iOS, Windows and Android — Norton gets points for its 24/7 live customer service phone support and 60-day money-back guarantee. Norton, long known for excellence in security products, has a relatively limited offering in its VPN product. In our testing, all of CyberGhost’s apps consistently took an abnormally long time to connect to a server. Its comparatively slow speeds — we measured a 44% average internet speed loss — severely lagged behind our top picks, which ranged from 3% to 24%.
Fast, Secure Streaming
Each protocol uses different methods to create a secure tunnel. An SSL VPN uses the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocol to encrypt browser-based connections. But an employee working from home usually connects through a remote access VPN.
And as post-quantum security standards have evolved, ExpressVPN has kept pace with those changes by integrating ML-KEM to beef up its post-quantum protections. With OpenVPN on Windows, ExpressVPN implemented Data Channel Offload, which boosts speeds by handling data packets more efficiently. ExpressVPN cooked up inventive solutions on both Lightway and OpenVPN connection protocols on its latest Windows app. We measured an 18% average speed loss in our latest speed tests with ExpressVPN thanks to upgrades to its connection protocols, making Express the third-fastest VPN we tested this year. Contrast that with Surfshark, whose base VPN plan offers unlimited simultaneous connections, a fuller feature set (including extras like Alternative ID) and costs $48 for the first 15 months and renews at $79 annually thereafter.
VPNs route all your internet traffic through one of its servers, where it is encrypted. Choosing the right VPN involves evaluating security, performance, compatibility, and service reliability to ensure safe, efficient, and uninterrupted internet access based on individual or organizational requirements. The primary functions of a VPN are to secure your data through encryption and provide online anonymity. A proxy serves as an intermediary between a user’s device and the internet, routing traffic through its server to change the user’s IP address.
Additionally, customer support may be minimal or non-existent, making it challenging for users to receive assistance or resolve technical issues promptly. Some free VPNs rely on advertising or data collection to generate revenue, impacting user privacy. Much like a spectrum of services available today, VPN applications come in two models, free and premium paid versions, each with a unique set of perks. Based on these criteria, the VPN you choose may be free or paid, each providing different features and security levels.
Regardless of the VPN protocol or server we used, Proton provided usable speeds for bandwidth-demanding activities like streaming 4K video or online gaming. Boasting an impressive 16% average internet download speed loss in our 2025 benchmarking, Proton VPN remained snappy even on geographically distant servers. Despite a few limitations with Proton’s free plan — you can’t manually select a server, and you’re limited to one connection at a time — it doesn’t sacrifice privacy, sell your data or plaster your screen with ads. Its privacy features, like discreet app icons on Android and guest modes, coupled with fast speeds and outstanding streaming service unblocking, make Proton VPN a solid option for casual users and privacy buffs alike. While Proton VPN’s free plan is excellent, its premium plan holds its own against the likes of ExpressVPN, NordVPN and Surfshark, and is a fantastic upgrade path for anyone who needs more servers for streaming and travel.
The VPN server then acts on your behalf to request your online banking page. But with a VPN, you connect to your VPN service, which encrypts all your data. Without a VPN, your data travels through the coffee shop’s public Wi-Fi network, potentially exposing your sensitive information to hackers. Suppose you’re in a coffee shop and want to access your online banking. In other words, the VPN server effectively acts as a middleman for your internet requests.
When you choose a VPN provider for your computer, they will likely offer a VPN app for your other devices such as your phone and tablet. Today, VPNs are used by individuals and organizations all over the world to protect their online privacy and security. This made it much easier and more cost-effective to connect remote workers to a central network, as they could now use the public internet instead of expensive leased lines. In the 1990s, as the internet became more widespread, companies began to use leased lines to connect their branch offices to a central network. In the 1970s, the first wide-area networks (WANs) were developed, allowing organizations to connect computers across large distances.

However, free VPNs have limitations like reduced speed and bandwidth, limited server locations, and potentially less robust security and privacy features. A good VPN should provide comprehensive features to ensure your online security and privacy. The most suitable choice depends on your specific requirements and priorities regarding data sensitivity, device compatibility, and performance expectations. It operates similarly to a regular VPN but is optimised for mobile platforms, ensuring privacy and security for users on the go.
Finding or showing your IP address is a simple process that can be done in a few steps, depending on the device you are using. It’s important to note that while your public IP address is essential for Internet connectivity, it can also pose privacy and security risks. Your public IP address plays a crucial role in your online experience. Think of it as your digital home address that enables you to send and receive data over the Internet. Check out our blog to learn more about how IP addresses work, their importance, and how to manage your online presence effectively. It’s assigned by your Internet Service Provider (ISP), allowing you to connect to the Internet through a network, whether at home, work, or on the go.
Personal VPN setup process
However, PIA’s sluggish server speeds make it unsuitable for users with slower or more unreliable internet connections. By testing across multiple devices and platforms, we’re able to assess which VPNs are best for gaming versus those best for streaming, torrenting or sharing sensitive information. Our rigorous testing spars casino process involves running over 250 internet speed tests across multiple worldwide servers to determine accurate internet speed loss averages. If all servers severely hinder your internet speeds, then streaming, browsing the web or hopping on Zoom calls may be be frustrating. When considering VPN server networks, look at the overall number of servers, as well as the individual country locations.
