ESET Tech Stack

Endpoint and mobile security platform protecting millions globally

Software Development Bratislava, Slovak Republic 1,001–5,000 employees Founded 1992 Privately Held

ESET operates a multi-layered security platform (Kafka + Spark + Impala + Scylla) designed for real-time threat detection across endpoints and mobile devices. The stack shape—heavy on streaming (Kafka, Flink) and distributed analytics (Spark, Hive, Impala)—reflects their core need to process and correlate threat signals at scale. Active adoption of STIX and TAXII, industry-standard threat intelligence frameworks, signals a strategic move toward standardized threat data exchange and automated response orchestration.
