We are a Bay-Area (California) based security data platform that enables teams to be more effective by building the infrastructure modern security teams need to most effectively use their security data.

This helps companies’ security analysts spend more time on what matters, remediating issues, by overcoming time-consuming data preparation tasks and compute intensive queries.
