Stonesoft started as a systems integrator in the Nordic regions of Europe. In 1994 it introduced StoneBeat, a technology for creating a high availability pair of firewalls in an active-passive configuration. In 1999, the company extended StoneBeat with a patented load balancing clustering technology, launching StoneBeat FullCluster. It was one of the first technologies certified in Check Point's OPSEC program.
