A comprehensive glossary of 246 terms used when discussing VPNs, security and encryption, privacy, networking and the internet.
Each definition has been carefully researched, written and edited to convey essential information quickly. Acronyms, concepts, protocols, standards and common brand names are included, and some slang is defined for completeness. Inevitably a definition will relate to other concepts or phrases in the glossary and, where true, we link them together for fast reference.
VPNs have quickly become popular amongst savvy internet users and even get coverage in mainstream media. Because of the technical nature of VPNs and computer networking in general, understanding VPN technology requires something of a specialised vocabulary.
Use the alphabet links at the top and bottom of each glossary page to browse definitions, which are listed in alphabetical order.
