Hillstone Networks was founded in 2006 by engineers from NetScreen, the firewall company Juniper had bought two years earlier, and it carries that lineage into its products. It operates from two headquarters, Santa Clara and Beijing, and says it serves more than 28,000 customers in over 60 countries, including more than a hundred of the Fortune 500. Its range is built around the firewall: the Hillstone Next-Generation Firewall line for perimeter security and the X-Series Data Center Firewall for high-throughput sites, with a network intrusion prevention system beside them. Its cloud products are CloudEdge for virtual firewalls, CloudHive for east-west traffic inside a virtualised data centre and CloudArmour for workload protection, managed through Hillstone iSource, CloudView, HSM and HSA. It competes directly with the larger firewall vendors in this index on price and throughput, and it is one of the few Chinese-founded network security firms with a substantial presence in Western markets.
