Tenzir was founded in 2017 and develops an open-core security analytics platform designed to simplify detection and response operations for cybersecurity teams. Its flagship platform, VAST, serves as a scalable Security Operations Center (SOC) backbone, helping enterprises, managed detection and response (MDR) providers, and service providers analyze security telemetry and threat intelligence efficiently. By leveraging open standards such as Apache Arrow and STIX, Tenzir reduces vendor lock-in and facilitates seamless integration across security tools. The platform decomposes traditional SIEM functionality into a flexible, federated architecture that can be deployed across cloud, hybrid-cloud, and edge environments, enabling organizations to build sustainable and interconnected security operations.
