BrByte Captor is a 64-bit, BrbOS-based operating system for network monitoring.
What BrByte Captor is
BrByte Captor is a 64-bit, BrbOS-based operating system for network monitoring. It collects and analyzes NetFlow V5, V9, and IPFIX, then presents real-time graphs and reports by protocol, MAC, port, IP, and ASN. Connection records include IP and port information, with connection and NAT logs for IPv4 and IPv6. Traffic can be examined by ASN or IP prefix without a BGP session or manual registration. Captor can combine data from multiple devices and organize collection filters by source, type, and IP; the number of collectors depends on the license. It can be installed on an existing machine suitable for server use, and the administrative panel is managed in a modern browser. USB and ISO images are available. The maker lists uses including bandwidth monitoring, provider and ASN traffic analysis, application and port monitoring, QoS validation, capacity planning, and finding worms, malware, or unwanted traffic. Paid plans are Level 1 at R$199 a month for 1 collector and 2 sources, Level 2 at R$299 a month for 2 collectors and 4 sources, and Level 3 at R$399 a month for 4 collectors and 8 sources.
