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

FireDaemon has released updated OpenSSL installers and binary distributions addressing seven security vulnerabilities disclosed in the April 7, 2026 OpenSSL Security Advisory. All users are strongly encouraged to upgrade immediately.

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.

FireDaemon legacy downloads are available for Fusion, Pro, and Zero products. Fusion 6.6.6 and 7.1.11 have been superseded by Fusion 8, with their final builds still downloadable as trials. FireDaemon Pro 4.6.3 and 5.4.17 have been superseded by Pro 6, with SHA-2 256 checksums provided for each installer. FireDaemon Zero 2.6.4 is end-of-life, and Zero 3.2.6 has been superseded by Zero 4. Licenses for all legacy versions are no longer sold, and OEM variants are no longer avail

FireDaemon Pro 6.4.2 ships with two new features, two improvements, and six bug fixes. Standard non-admin users can now restart services in their own session, a new CLI flag makes it scriptable, and critical fixes land for mapped drives, SCM recovery crashes, and more.

Not all versions of FireDaemon Pro are created equal and if you're still running Pro 4 or Pro 5, the gap is wider than you might think. Pro 6 isn't just an incremental update: it brings a preconditions engine, calendar-based scheduling, full service auditing with SACL visibility, and bulk credential management via CLI. Pro 4 is end of life. Pro 5 support ends April 2026. If you're on Windows Server 2025, Pro 6 is your only option.

We've shipped updates to all three FireDaemon products. Pro 6.3.5 adds Service Auditing, Windows Server 2025 dMSA support, bulk password rotation, 3x faster service definition loading, and a raft of UI and reliability fixes. Fusion 8.1.6 ships with OpenSSL 3.6.1. Zero 4.0.8 gets a toolchain update. All available now with 30-day free trials. Free update to existing customers and customers with software assurance subscriptions.
