Internet Security Systems

Internet Security Systems (ISS) was an Atlanta-based network and internet security company, founded in 1994, that provided vulnerability scanning, intrusion detection, and managed security services (Internet Scanner, RealSecure, Proventia, BlackICE). It was acquired by IBM in 2006 for approximately $1.3 billion and folded into IBM as IBM Internet Security Systems (later IBM Security / X-Force); it no longer exists as an independent company. Surfaced as a portfolio company of kleiner-perkins and added to the API Evangelist network as a stub, ISS operates no active, independent public developer or API surface today, so there is nothing live to enrich against.

Internet Security Systems is profiled on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, Network Security, and Vulnerability Management.
