VPN in 2026: what it is, why to use it, and which software to choose for smartphone and PC

Your internet connection is far less private than you think. Every time you browse from a smartphone, connect to a public Wi-Fi network, or simply search something on Google, you leave digital traces that are collected, analyzed, and often sold. In 2026, with digital surveillance at all-time highs and cyber threats becoming increasingly sophisticated, a VPN is no longer a tool for tech experts: it has become a practical necessity for anyone who wants to browse safely and freely.

But what exactly does VPN mean? The acronym stands for Virtual Private Network. In simple terms, a VPN creates an encrypted tunnel between your device and a remote server, hiding your real IP address and making data traffic unreadable to anyone trying to intercept it — from internet providers to cybercriminals, governments, and advertisers. It's like sending a letter inside a reinforced envelope instead of sending it on transparent cardboard.

In recent years, the spread of artificial intelligence in surveillance and profiling systems has made VPNs even more relevant. AI algorithms are now capable of analyzing enormous amounts of behavioral data in real time, building extremely detailed user profiles. At the same time, VPNs themselves have integrated artificial intelligence into their own software to optimize connections, detect malware, and block trackers proactively. The sector has transformed, and in this guide, we explain everything you need to know.

How a VPN works: the mechanism under the hood

To truly understand why a VPN is useful, you need to understand how it works technically, without getting into inaccessible jargon. When you browse normally, your smartphone or computer connects directly to websites, and your IP address — a sort of digital license plate — is visible to anyone: the website you visit, your internet provider (ISP), and potentially anyone monitoring the network.

By activating a VPN, your device first establishes an encrypted connection with a VPN server located elsewhere in the world — it could be in Milan, London, or New York. From that moment on, all traffic passes through that server: websites see the VPN server's IP, not yours. Your ISP, in turn, sees only that you've connected to a VPN server but cannot see what you're doing.

The encryption protocols used are fundamental. In 2026, the most widespread and reliable are:

  • WireGuard: the most modern, lightweight, and fast. Ideal for smartphones because it uses less battery
  • OpenVPN: open source, proven, available on all major operating systems
  • IKEv2/IPSec: excellent for mobile devices, thanks to the ability to reconnect quickly when you change networks
  • Lightway (ExpressVPN) and NordLynx (NordVPN): proprietary protocols based on WireGuard, optimized with artificial intelligence algorithms to reduce latency

An often underestimated element is the kill switch: a feature that automatically interrupts your internet connection if the VPN disconnects, preventing your data from being exposed unintentionally. In 2026, all quality VPN software includes it as standard.

Why use a VPN in 2026: concrete use cases

The reasons why millions of Italians have started using a VPN in recent years are multiple and concrete. It's not paranoia: these are situations that affect the daily life of anyone using the internet.

1. Protection on public Wi-Fi networks

Cafes, airports, hotels, libraries: every time you connect your smartphone to an open Wi-Fi network, you potentially expose your data to interception. "Man in the middle" attacks, in which a malicious actor positions themselves between you and the router, are technically simple and still very common. A VPN makes them practically useless.

2. Privacy from advertising profiling

The artificial intelligence used by advertising platforms today is capable of building extremely detailed psychographic profiles. Every search, every click, every second of viewing is recorded. A VPN with integrated tracker blocking — like those offered by the best software in 2026 — drastically reduces this commercial surveillance.

3. Access to geo-blocked content

Want to watch a series available only on Netflix USA or BBC iPlayer? With a VPN, you can connect to a server in the desired country and access catalogs that would otherwise be inaccessible from Italy. The same applies to music streaming services, news sites, and sports platforms.

4. Security for remote work

Remote working is now structural for millions of Italian workers. Corporate VPNs protect communications between employees and company servers, but even solo workers have an interest in encrypting their connections when handling sensitive client data.

5. Protection from stalkerware and surveillance systems

With the expansion of AI-based monitoring systems, in some countries access to free information is limited. A VPN ensures freer browsing, although it's not an infallible solution against governments with advanced resources.

Which VPN to choose in 2026: comparison of the best software

The VPN market is crowded: there are hundreds of services, many of questionable quality or even dangerous (some free VPNs collect user data and resell it). Here's an overview of the best software in 2026, with particular focus on artificial intelligence integration and smartphone compatibility.

NordVPN

Remains one of the absolute references. In 2026, it has strengthened its Threat Protection Pro engine, based on AI, which analyzes downloaded files in real time, blocks malware before it reaches your device, and neutralizes trackers with effectiveness superior to traditional blocking. The smartphone app — available on Android and iOS — is intuitive and supports Multi-hop (connection through two VPN servers for maximum privacy). No-log policy verified by independent audits.

ExpressVPN

Speed is the keyword. The proprietary Lightway protocol, optimized with machine learning algorithms, guarantees ultra-fast connections even from mobile. Excellent for streaming, it supports up to 8 simultaneous devices. More expensive than average, but justified by software quality and 24/7 customer support.

Surfshark

The best value for money in 2026. Unlimited devices with a single subscription — perfect for families or those with many smartphones and computers. It has introduced an AI-based ad blocker that is particularly aggressive and effective. The Nexus feature allows you to route traffic through the entire server network instead of a single node.

ProtonVPN

The choice for those who put privacy first and foremost. Developed by the same creators of ProtonMail, it is based in Switzerland (jurisdiction favorable to privacy), has publicly verifiable open source code, and a free version with unlimited data — unique among reliable providers. Integration with Proton Pass (password manager) and Proton Drive creates a complete privacy ecosystem.

Mullvad VPN

For the most demanding in terms of anonymity. Accepts payment in cash and cryptocurrency, doesn't require email for registration, assigns a random identification number. Less accessible for beginners but unbeatable for those who want maximum anonymity.

What to absolutely avoid: completely free VPNs without a clear business model (like Hola VPN or similar), VPN software from unknown sources downloaded from unofficial stores, and services without a verified no-log policy.

VPN and artificial intelligence: the future of digital security

In 2026, artificial intelligence is not just a tool in the hands of those who want to profile users: it has become an essential component of the best VPN software. This integration has transformed the VPN from a simple encryption tunnel into a proactive and adaptive security platform.

Modern AI systems integrated into VPNs are capable of:

  • Automatically selecting the optimal server based on latency, traffic load, and geographic location, ensuring the fastest connection possible at all times
  • Detecting anomalous behavior in the network and alerting the user in real time to potential threats, such as phishing attempts or suspicious connections
  • Dynamically adapting the connection protocol based on network conditions, automatically switching from WireGuard to OpenVPN if the first one is blocked
  • Analyzing DNS to identify and block domains associated with malware, ransomware, and advertising trackers before your browser even contacts them

On the smartphone side, AI also optimizes battery consumption: new energy management algorithms reduce the impact of VPNs on mobile device batteries by about 30% compared to traditional implementations, one of the main friction points that discouraged many users from using an always-on VPN.

The next frontier is post-quantum VPN: as quantum computers advance rapidly, some providers like NordVPN and ProtonVPN have already implemented or are testing encryption protocols resistant to quantum attacks, anticipating a threat that could materialize in the coming years.

Frequently Asked Questions

Q: Does a VPN slow down my internet connection? A: Yes, slightly, but in 2026 the impact is minimal with the best software. Modern protocols like WireGuard and high-capacity servers reduce speed loss to 5-15% under normal conditions. For 4K streaming or online gaming, choose servers geographically close to you.

Q: Is it legal to use a VPN in Italy? A: Absolutely yes. In Italy and throughout the European Union, VPN use is perfectly legal. What remains illegal are the activities you carry out through a VPN: the VPN doesn't make you unpunishable, it just gives you more privacy.

Q: Are free VPNs safe? A: Most are not. Free services need to monetize somehow, and they often do so by selling user data or injecting advertising. The only reliable exception in 2026 is ProtonVPN Free, which offers free servers with unlimited bandwidth but reduced speed.

Q: Does a VPN protect me from viruses and malware? A: Not directly. A VPN encrypts traffic and can block connections to known malicious domains, but it doesn't replace antivirus software. Some VPN software (like NordVPN with Threat Protection) integrate antimalware functions, but for complete protection, use both tools.

Q: Can I use a VPN on my smartphone always active? A: Yes, and it's recommended. Modern VPN software for smartphones is designed to run in the background with minimal battery impact, thanks to artificial intelligence-based optimization. The "always-on VPN" mode is available on both Android and iOS.

Conclusion

In 2026, using a VPN is no longer a choice for IT experts: it's a decision of common sense for anyone who uses the internet — which means practically all of us. Whether you want to protect your smartphone on public networks, escape AI-based profiling, or access geo-blocked content, modern VPN software offers accessible, fast, and increasingly intelligent solutions.

Our practical advice: start with ProtonVPN Free if you want to test the service without spending anything, or consider NordVPN or Surfshark if you're looking for a complete service at a competitive price. Whatever choice you make, make sure the provider has a verified no-log policy and a functioning kill switch. Your digital privacy is worth much more than the cost of a monthly subscription.
