What are the differences between ProtonVPN and SurfShark?

ProtonVPN and SurfShark are both widely recognized Virtual Private Network (VPN) services, but they offer differing features which cater to various user needs. ProtonVPN is known for its strong focus on privacy and security, originating from the company that brought us the secure email service ProtonMail; it boasts a no-logs policy certified by Swiss privacy laws and offers Secure Core servers meant to protect against network-based attacks. On the other hand, SurfShark distinguishes itself with unlimited simultaneous device connections, allowing more flexibility for users with multiple devices. It also provides features like CleanWeb to block ads, trackers, and malware. While both services enable access to geo-restricted content, support strong encryption protocols, and offer kill switch functionality, ProtonVPN has a free tier option with limited features, whereas SurfShark requires a subscription but often promotes competitive pricing plans. The choice between the two might come down to whether one prioritizes the advanced security measures and reputation of ProtonVPN or the generous device policy and additional features of SurfShark.
