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.
