Siemens

Siemens is one of the largest industrial manufacturers in the world, and its presence in this index comes from the factory floor rather than the office. It builds the programmable controllers, drives and automation systems that run industrial plant, and it sells the network security products that protect them. SCALANCE S, listed here, is its industrial security appliance line: firewalls and VPN devices built for automation networks, understanding the industrial protocols those networks carry and rated for the conditions a plant imposes. They are sold as part of the SIMATIC and SCALANCE industrial networking range and managed with Siemens' own tools. Siemens also runs one of the more active product security incident response teams in industry, publishing advisories on its own equipment. Products of this kind are certified to IEC 62443 rather than tested by malware laboratories, which is why those columns are empty here.
