About TENEX.AI

TENEX sells managed detection, not another analyst copilot. Agents ingest the customer's existing SIEM and EDR, dispose of the queue at machine speed, and leave named analysts for the cases that still need a human.

Founded by operators who previously ran a large Google security partner, it is an 18-month-old MDR with unicorn capital behind a human-led delivery model.
