The main product of MikroTik is a Linux-based operating system known as MikroTik RouterOS. It lets users turn a selected PC-based machine into a software router, allowing features such as firewall rules, VPN Server and Client, bandwidth shaper Quality of Service, wireless access point and other commonly used features for routing and connecting networks together. The system is also able to serve as a captive-portal based hotspot system. The operating system is licensed in escalating levels, each releasing more of the available RouterOS features as the level number rises. Licensing is fee based and escalates with the released features. There is a software called Winbox which provides a sophisticated GUI for the RouterOS operating system. The software also allows connections via FTP, telnet, and SSH. There is also an API which allows creating customised applications for management and monitoring.
