Doctor Web sells the Dr.Web line, a scanner with an unusually long and unbroken lineage: Igor Danilov wrote the first version in 1992, and the company that sells it was established in 2003 around that engine. It is Russian, headquartered in Moscow, and privately held. Its distinguishing technical claim is independence. Dr.Web uses its own detection engine and its own virus laboratory rather than licensing anyone else's, and it is one of a small number of vendors of which that is true — most products in this index that are not from an engine owner are running someone else's technology under their own name. Households buy Dr.Web Security Space, with a version for mobile devices; organisations buy Dr.Web Enterprise Security Suite, which covers workstations, servers, mail gateways and mobile devices under one console, with Dr.Web KATANA for behavioural protection and a Linux line for servers. The company also sells to hosting providers and telecoms, where its products are administered on a subscription basis rather than per licence. Vendor page →
