A Linux-based operating system from Net Integration Technologies Inc., Markham, Ontario, known for its comprehensive and unique package of services. In 2008, the company was acquired by IBM, and Nitix was made part of Lotus Foundations. Nitix automatically discovers the network it is connected to, sets up the firewall and reconfigures it as services are added and deleted. It provides unattended, automatic backups and disk-based recovery in the event of failure. Nitix also manages up to five ISP connections, load balancing between them and manages failover if one goes down.
