SecureIM is an encryption system built into the Trillian Instant Messenger Client.
Trillian Pro also has a stream manipulation feature labelled 'time travel', which allows the user to record, and subsequently review, pause, rewind, and fast forward live video and audio sessions. XML-based history makes the log easy to manipulate, searchable and extendable for future functions. Pro has a History Manager that shows the chat history and allows the user to add bookmarks for revision later on. Trillian Pro comes with Activity History, and both log the history as both plain text files and as XML files. Subcontacts will appear under the metacontact as small icons aligned in a manner of a tree. To eliminate duplicates and simplify the structure of the contact list, users can bundle multiple contact entries for the same person into one entry in the contact list, using the Metacontact feature (similarly to Ayttm's fallback messaging feature).
Trillian 5 for Windows was released in May 2011, and Trillian 6.0 was initially released in February 2017. On August 14, 2009, Trillian "Astra" (4.0) for Windows was released, along with its own Astra network. A previous version of the official web site even had a tribute to Douglas Adams on its front page.
The program was named after Trillian, a fictional character in The Hitchhiker's Guide to the Galaxy by Douglas Adams.
