About Senrio

About Us

Built by a team of veteran security researchers, CISOs, developers, and former defense/intelligence officers, Senrio Inc's platform instantly identifies, classifies and categorizes all the devices on your network, adding information about them to a living, dynamic record. All of this is done passively, without agents, and leveraging only network metadata.

The company was incorporated in 2015 and is based in Portland, Oregon.

Our Name

Senrio is a shortened version of the Japanese word "senrigan" (千里眼). "Senrigan" is a lacuna word which means "clairvoyant reflex", "foresight", or "to see through". It is the ability to perceive things not evident to the senses and then act accordingly.
