ZoomEye: 9,112 Indexed Kafka Endpoints vs 1,377,501 Services on Port 9092

A ZoomEye scan on 23 September 2026 found 9,112 assets matching the Kafka fingerprint and 1,377,501 services on port 9092, Kafka's default broker port. The fingerprint figure is a lower bound on Kafka deployments, while the port count covers all listening services on that port.

• Fingerprint query app="Kafka" returned 9,112 assets; port 9092 returned 1,377,501
• The two figures should not be combined: fingerprint understates, port overstates Kafka
• An unauthenticated broker lets clients list topics and alter cluster config
• Recommended fix: restrict broker ports via network controls, not credentials
