Do not capitalize extranet or intranet.

Articles

Use the articles the and an with extranet and intranet.

  • The extranet is for all our customers, while the intranet is for staff only.

Prepositions

The prepositions on and to are most often used with extranet and intranet.

  • The department will make its training information available on the intranet.
  • Students will also have access to the extranet next semester.

However, the context determines what preposition you should use. Other prepositions besides on and to may be appropriate.
