This episode is sponsored by Exaforce. Exaforce was created to handle the complete security operations workflow - detect, triage, investigate, respond. Exabots autonomously manage every stage, eliminating gaps between alert and action that slow down traditional security operations. And how it works is simple too: the exabots ingest all security data and then semantically connects it to understand the full context of security events and how they relate to each other.
