Standard licenses are perpetual and priced per machine, starting at $45.00, with volume discounts available for 2 or more licenses.

The FireDaemon Fusion compatibility matrix maps Microsoft Windows operating system versions to specific Fusion and Fusion OEM software versions. It covers Fusion 6, 7, and 8 across both 32-bit and 64-bit systems. Fusion 8 is the current release and no longer supports 32-bit systems. Fusion 6 has reached end of life. The matrix distinguishes three statuses: Compatible/Supported, Compatible/Unsupported (typically due to the OS reaching end of support), and Incompatible/Unsuppor

The FireDaemon Fusion changelog documents the full version history of Fusion and Fusion OEM, spanning releases from the initial beta in 2010 through to the current Fusion 8 series. 8 is the current actively developed release, Fusion 7 is in critical bugfix-only mode, and Fusion 6 has reached end of life. The changelog uses four markers to categorise changes: N for new, I for improvement, F for fix, and S for security.
