Scrutinizer Free NetFlow & sFlow traffic analysis and reporting solution.
Flow Analytics is a company wide reporting solution for:
- Archiving of Scrutinizer database beyond 24 hours (i.e. infinite years of data can be saved at selectable intervals). The free version of Scrutinizer drops all data at midnight.
- Adds several additional traffic analysis Report Types (e.g. Flows, Flow Volume, NBAR Support, etc.).
- Report on Top Applications, Conversations, Flows, Protocols, Domains, Countries, Subnets, etc., across dozens of routers and switches.
- Any saved report in Scrutinizer can be configured with a threshold to trigger an alarm.
- DNS resolution becomes automated and a constant process.
- Network traffic reporting and alarming on the internal network: SYN, NULL, FIN, XMAS Scans, RST/ACK worms, P2P, ICMP Unreachable, illegal IP addresses, excessive Multicast traffic, known compromised Internet hosts and more.
Distributed Collectors can be used to analyze network traffic enterprise-wide, from a central location. Dozens of distributed collectors can be supported for companies with thousands of NetFlow and sFlow exporting devices (i.e. routers and switches).
Service Providers can take advantage of the SPM (Service Provider Module), which allows permissions to be configured per router, switch, interface, etc. per login account. Customizable billing solutions for overusage and invoicing.
Flowalyzer Free NetFlow Tester can be used to test NetFlow v5 and v9. A very popular free tool.
