Protect your online privacy with a VPN client

A VPN is crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
