SOURCENEXT

SOURCENEXT is a Japanese software publisher listed in Tokyo, and it is a distributor rather than a developer of security technology: its business is licensing other companies' engines and selling them in Japan under its own ZERO brand, at prices built around a one-off purchase rather than an annual subscription — an unusual model that has made it a large presence in Japanese retail. Two of its products appear here. ZERO ウイルスセキュリティ (Virus Security ZERO) is built on K7 Computing's engine, and ZERO スーパーセキュリティ (Super Security ZERO) on Bitdefender's. Both are sold with what the company describes as lifetime licensing for the installed machine. For this index that is the essential context: a test result for a SOURCENEXT product is, in substance, a result for the engine inside it. Read it alongside the K7 and Bitdefender rows rather than as independent evidence.
