Algo VPN uses Ansible scripts to easily set up a secure personal IPSEC (IKEv2) and WireGuard VPN, supporting major cloud providers and no client software on most devices. It uses strong encryption (AES-GCM, SHA2, P-256), generates Apple profiles, and offers optional features like ad-blocking and SSH tunneling. Setup involves preparing your environment, configuring users, and running the Algo script to deploy on a new VM or existing Ubuntu 18.04 server. Clients use generated config files or scripts for seamless connection on iOS, Android, Windows, macOS, and Linux.
