Dragonfly Sensor

Designed for Threat Hunters

Dragonfly Threat Sensor (DTS) integrates signature inspection and full packet capture with streaming machine learning to detect zero-day exploits, target malicious activity, and drive security automation. DTS operates at wire speed, up to 100Gbps, to significantly reduce time to detection and response. For ease of integration with third-party applications and tools, DTS generates data and alerts in industry-standard formats and implements a simple RESTful application programming interface (API).

Dragonfly seamlessly integrates Suricata, an industry standard, open-source, intrusion detection engine.  It is the primary source of data for the sensor ML pipeline.  Signature inspection is used to detect and alert on known threats.  Simultaneously, deep packet inspection is used to efficently extract and generate meta-data.



Dragonfly implements a fast, flexible, machine learning engine for serving descriptive and predictive models. The engine consumes data from the sensor ML pipeline to analyze and score features.  Its primary function is to produce threat scores to help drastically reduce false positive and significantly increase detection of zero-day attacks.



Dragonfly incorporates a dynamic packet capture engine to selectively index and record network traffic at wire speed. It maintains a large ring buffer to facilitate retrospective recording of connections at the beginning of the session.   The engine utilizes threat scores to determine the packet recording and retention policy for each session.
