Caligare Flow Inspector vs ElastiFlow

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.

ElastiFlow collects and analyzes network flow and telemetry data for network observability and security analytics. Its performance and availability solution is intended to help network operations and engineering teams find and resolve issues across complex, distributed environments. It handles NetFlow, IPFIX, and sFlow, with application visibility, conversation analysis, and bandwidth monitoring. NetObserv offers visibility, open-data-platform integration, pre-built dashboards, and machine-learning jobs. ElastiFlow extracts more than 6,200 standard and vendor-specific fields from flow records and enriches them with GeoIP, autonomous-system, and IP-reputation information. Supported platforms include Elasticsearch, Elastic Cloud, Elastic Cloud Enterprise, OpenSearch, AWS OpenSearch Service, Apache Kafka, Confluent Platform, Redpanda, Splunk, and Cribl Stream. Deployment options include Docker, Linux, Ansible, and Helm. The virtual appliance supports VMware ESX, Proxmox, and KVM, and is intended for up to 16,000 flows per second from one location. Basic costs nothing and supports up to 4,000 records per second and 25 SNMP devices. A 30-day trial is available.
