Caligare Flow Inspector vs Plixer Replicator

Caligare Flow Inspector analyzes NetFlow exports from existing routers, without requiring deployed probes. Its web-based management interface configures collectors, network devices, application groups and anomaly detection. The software provides real-time network analysis, user data tracking, and statistics for hosts, protocols, applications and conversations. Caligare says this visibility can help identify suspicious activity, denial-of-service attacks, worm-infected stations, bottlenecks and routing trouble. The free edition supports NetFlow versions 1, 5, 6, 7 and 9, along with low-level traffic search, interface utilization, maps, filtering and forwarding. It also offers local, LDAP or external authentication and user and group management. The free license is for non-commercial use and is limited to two devices, 24-hour history and 250 flows per second. Professional and Enterprise editions add longer-term trends, network anomaly detection, unrestricted NetFlow parsing and commercial use. Linux packages are listed; the latest version requires MySQL 5.1 or newer. A 30-day trial key can be requested by email.
