Proton VPN for Windows: Privacy, Kill Switch, and Modern VPN Features

Proton VPN is a well-known privacy-focused VPN service with a dedicated Windows app. Its current client combines encrypted VPN connections with features such as a kill switch, split tunneling, alternative routing, and optional NetShield filtering.

What a VPN changes

A VPN creates an encrypted connection between your device and a VPN server, so traffic travels through that tunnel before reaching the wider internet. Websites normally see the VPN server’s IP address rather than your home connection’s public IP. This can be useful on untrusted networks, for privacy, and for connecting through a different location. A VPN does not make you anonymous everywhere, and it does not protect you from every type of tracking or malware.

Proton VPN’s Windows application

The Windows app is designed to be simple enough for everyday users while still providing advanced controls. The official download page supports standard Windows devices as well as a dedicated ARM build. Free users can connect through the free offering, while paid plans expand the number of available servers and locations and add premium capabilities.

Kill switch and leak protection

The kill switch is one of the most important practical features. If the VPN connection unexpectedly drops, the app can prevent normal internet traffic from continuing outside the tunnel until the connection is restored. Proton also documents DNS and IPv6 leak protection. These protections matter because a VPN that briefly exposes your real connection during a network change can undermine the privacy goal of using it in the first place.

Secure Core, NetShield, and split tunneling

Premium features include Secure Core routing, which sends traffic through multiple servers before leaving the Proton network. NetShield can filter domains associated with malware and can also block trackers and ads on supported plans. Split tunneling lets you decide which applications or websites should use the VPN and which should continue over the normal connection. This is especially useful when a local service or game does not behave well through a VPN.

Recent Windows improvements

Proton’s Windows release notes document ongoing improvements to its connection protocols. Recent releases have included changes to Proton Protocols, automatic network conflict detection, connection feedback, and reliability fixes around IPv6 and reconnection behavior. The current app is therefore not static software; checking the release notes can help explain changes you notice after an update.

Choosing a VPN sensibly

Do not judge VPN software only by the number of countries advertised. Look at the provider’s logging policy, security model, app transparency, protocol design, and how the service behaves on your specific connection. Proton states that its apps are open source and audited and that it follows a no-logs policy. Users should still read the provider’s current privacy documentation and choose the plan that matches their needs rather than assuming every VPN offers the same level of protection.

Download from Proton
