Stormshield Network Security (SNS) is a range of firewalls for protecting corporate and industrial networks, supplied as hardware appliances and as virtual appliances. Functions include intrusion prevention and detection, application control, antivirus, URL filtering, vulnerability detection, antispam and antiphishing, and SD-WAN connectivity. The range covers UTM, next-generation, hardened and industrial firewalls, for both IT and OT networks.
Stormshield is a French company headquartered in Issy-les-Moulineaux and a wholly owned subsidiary of Airbus Defence and Space Cyber Programmes. The firewalls run on equipment that the customer operates, as a physical device or a virtual machine, so traffic is inspected within the customer's own environment. The SNS firmware is certified to Common Criteria EAL4+ by ANSSI in France and holds approved and qualified status with the CCN in Spain. The software is proprietary. For European organisations, particularly in public administration and critical infrastructure, European ownership and national certification are relevant when choosing a perimeter firewall.
