Using a VPN can help to protect your privacy. You can use a VPN to appear like you are in another country to reach a website that was previously blocked, to stop your ISP from restricting you to certain websites, and when travelling to protect your data while using insecure WiFi. There’s another: ad blocking.
Keeping your software updated is important. You get the newest features, and more importantly, you also get the latest security fixes. This Ansible role can automate the updates to your Ubuntu, CentOS, and Redhat servers with the latest packages, reboot if needed and wait for the server to start up.
