extranet
C1Technical/Formal, Business/Corporate
Definition
Meaning
A private computer network that uses internet technology and public telecommunication systems to provide secure access for authorised external users (e.g., suppliers, customers) to an organisation's intranet.
While strictly a network, the term often refers to the collaborative platform or portal itself, facilitating business-to-business communication, data exchange, and shared workflows between separate organisations.
Linguistics
Semantic Notes
The term is a portmanteau of 'extra-' (outside) and 'net' (network). It implies a controlled extension of an internal network, distinguished from the public 'internet' and the wholly internal 'intranet'. It is inherently a security-conscious concept.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct transliteration "экстранет" as it is not widely established; the English term is often used. Do not confuse with "интернет" (internet) or "интранет" (intranet). The concept is specific and technical.
Common Mistakes
- Using 'extranet' to mean a public section of a company website. Confusing it with 'intranet'. Using it as a verb (e.g., 'We need to extranet this data' – incorrect).

FAQ
Frequently Asked Questions
An intranet is a private network accessible only to an organisation's employees. An extranet extends that network securely to authorised external parties like suppliers, partners, or customers.
It uses internet technology and often the public telecommunications infrastructure, but it is a private, gated section, not part of the open, public internet.
Authorised external users such as a company's suppliers, wholesale customers, distributors, franchisees, or collaboration partners.
Yes, the concept remains highly relevant. Modern cloud-based collaboration platforms (like SharePoint Online, partner portals in Salesforce) are essentially the functional evolution of the traditional extranet.
