ProtonVPN is a virtual private network service developed by Proton AG, the same team behind Proton Mail. Designed around a privacy-first philosophy, ProtonVPN combines strong encryption, audited software, and a Swiss legal base to offer users a secure way to protect their internet traffic and identity. Core features and security ProtonVPN supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2, allowing users to balance speed and compatibility. Traffic is encrypted with industry-standard algorithms (AES-256 and ChaCha20 where applicable), and apps include essential protections such as a kill switch to block traffic if the VPN connection drops. ProtonVPN operates a strict no-logs policy and is headquartered in Switzerland, which has strong privacy laws and is outside EU/US intelligence-sharing agreements. The company’s apps are open source and have undergone independent security audits, increasing transparency and trust. Secure Core, Tor over VPN, and NetShield A standout capability is Secure Core: multi-hop routing that sends traffic through ProtonVPN-controlled servers in privacy-friendly countries before it exits to the public internet. This reduces the risk of traffic correlation attacks. ProtonVPN also provides a Tor over VPN option to route traffic into the Tor network directly from the VPN client, making it easier to combine both technologies. NetShield is a built-in ad and tracker blocker that can also prevent access to known malware domains, improving privacy and security across devices. Platforms, performance, and usability ProtonVPN offers native apps for Windows, macOS, Linux, iOS, Android, and some routers. Its interface is straightforward for beginners but also provides advanced options like split tunneling and custom DNS settings. WireGuard support boosts performance and reduces latency compared with older protocols, making ProtonVPN suitable for streaming, gaming, and bandwidth-intensive tasks on paid plans. P2P/torrenting is permitted on specific servers. Plans and free tier ProtonVPN provides a free tier with limited servers and speeds, which is useful for basic privacy needs. Paid tiers unlock more servers, access to Secure Core, faster speeds, and higher concurrent connections. Pricing is competitive for the features offered, and Proton periodically bundles VPN access with other Proton services. Considerations No VPN can guarantee absolute anonymity, and performance can vary by server and location. Users in highly restrictive jurisdictions should evaluate local laws and risks before use. Overall, ProtonVPN is a strong option for those prioritizing transparency, security, and privacy protections backed by a company with a clear focus on user rights.
