| TrackerIQ is an application-centric insider threat detection platform based on Activity Flow Analytics, both SaaS or on-prem. Today’s detection solutions are geared towards infrastructure, authentication, and data access use-cases - they don’t analyze user activity flows on the application layer after the user has logged in.TrackerIQ is poweredby a patent-pending clustering engine that was developed for grouping the user’s activity flows and generating profiles. The Activity Flow Analytics model is based on activities performed by the user, the order in which they were performed, and the time gaps between these activities. Since each user has many activity flows per application, TrackerIQ learns for each user (or group of users) his/her activity flow profiles. These profiles enable an accurate detection of anomaly activity flows.SaaS security , Anomaly detection for SaaS , Insider Threat Protection , CDR, Cloud Detection Response, and SaaS Detection and Response | $23M / Series A / Jun 21, 2022 | ||
