Proton VPN Plus is a cybersecurity service that includes a feature called NetShield, which blocks online advertisements at the DNS level. This means it stops ads before they load on a device by preventing access to the servers that host them. NetShield is available on Android and iOS smartphones, as well as on Windows and macOS computers and tablets. Currently, it's being offered with a 70% discount, reducing the first-year subscription cost to as low as 2.99 euros per month, compared to the regular price of 9.99 euros. This discount saves users 168 euros over a 24-month subscription. After the initial period, the subscription renews automatically at 6.99 euros per month. The service also includes a 30-day money-back guarantee. Customer support is available 24/7 through chat and email in English, with the ability to assist in French. NetShield is specifically designed to block ads within mobile applications, a task that many traditional ad blockers cannot accomplish, as they are usually limited to web browsers. It works by filtering the device's web traffic and identifying potential ad sources, which can improve the performance of apps like games that are often slowed by ads. However, it does not block ads embedded directly in video content, as these are difficult to distinguish from the actual video material. In addition to NetShield, the Proton VPN Plus suite includes a virtual private network (VPN) that hides the user's real IP address and geolocation. This helps protect online privacy and allows users to access content from different regions by connecting to one of the service's more than 20,681 servers spread across 148 countries. The service is noted for its transparent infrastructure, strong performance when connecting to nearby servers, and tools to bypass internet censorship. However, it is generally more expensive than some of its competitors, and customer support quality has been reported to vary based on user experiences. NetShield also enhances online safety by blocking tracking technologies and preventing access to potentially harmful websites through pre-blocking and threat detection. These features are part of the broader Proton VPN Plus security suite, which combines the ad-blocking capabilities of NetShield with the privacy protection of the Proton VPN. A detailed review of this suite is available from the Clubic editorial team, offering further insights into its performance and features.
