Cisco Telemetry Broker (CTB) is a telemetry pipeline product that sits between telemetry producers (network devices, cloud flow logs, sensors) and telemetry consumers (security analytics, NDR/XDR, SIEM, observability tools). Its core functions are to route/replicate, filter, and transform telemetry streams so multiple tools can consume the same data without reconfiguring every exporter for every destination.
Commonly cited capabilities include:
- Brokering/replication: one-to-many forwarding of telemetry feeds to multiple consumers.
- Filtering: dropping/allowing subsets of traffic/records per destination (fine-grained control).
- Transformation: protocol/format translation (for example, AWS VPC Flow Logs → IPFIX for on‑prem collectors/tools).
