Secure and private internet browsing

Proton VPN is a virtual private network (VPN) service designed to protect your online privacy and security. It encrypts your internet connection, helping you browse anonymously and safeguard sensitive information from hackers and trackers. With servers worldwide, it ensures a safer and more private online experience.

Developed by the team behind Proton Mail, Proton VPN focuses on transparency, strong encryption, and user privacy. It offers both free and paid plans, catering to casual users and those needing advanced features. Whether on desktop or mobile, it works to keep your online activity secure without logging user data.

Proton VPN uses AES-256 encryption and secure VPN protocols such as OpenVPN, IKEv2/IPSec, and WireGuard to ensure strong data protection. Its Secure Core technology routes traffic through hardened servers in privacy-friendly countries, reducing risks of network-based attacks. While it includes a kill switch and DNS leak protection, connection speeds on distant servers can be inconsistent, which can frustrate users seeking reliable performance across all locations.

Comprehensive security and privacy features

The service supports VPN over Tor for added anonymity and includes split tunneling, letting users route specific apps or websites outside the VPN. It provides NetShield, a DNS filtering tool that blocks ads, trackers, and malware. Additionally, it features Perfect Forward Secrecy, which regularly changes encryption keys, ensuring that even if a key is compromised, past session data remains protected and inaccessible to potential attackers.

Although ad-free and without data limits, the free version only offers servers in three countries at medium speeds. Paid plans provide access to 3,000+ servers in 65+ countries, higher speeds, Secure Core, and advanced tools for personal or business needs. Alternatives such as NordVPN, ExpressVPN, and Windscribe compete, but this program’s open-source apps, no-logs audits, and transparency reports make it a trusted choice for users prioritizing privacy and strong security.

Reliable privacy with strong security

Proton VPN delivers robust privacy protection, advanced security features, and transparent policies, making it a highly trustworthy choice for users. Its modern encryption protocols, Secure Core architecture, and open-source development significantly enhance reliability and user confidence. Although speeds may fluctuate on distant servers, it stands out as an excellent option for anyone seeking comprehensive digital privacy, strong security measures, and a commitment to transparency in protecting online activity.
