Panther
Panther is a SIEM / SOC & Detection company founded in 2018 and based in San Francisco, United States. It has raised $140M in total funding, most recently a Series B in 2021.
Founded in 2018 by Jack Naglieri, Panther (formerly Panther Labs) is a cloud-native SIEM that lets security teams write detections as code and run them against a highly scalable security data lake, an approach aimed at the volume and cost problems of monitoring at cloud scale. The company raised a $120 million Series B in December 2021 led by Coatue at a unicorn valuation, for roughly $140 million total raised. In 2026 Panther introduced an AI SOC platform with agents that improve over time. On June 16, 2026, Databricks announced an agreement to acquire Panther to extend its security lakehouse strategy; the deal had not yet closed as of this writing and remained subject to customary closing conditions.
Panther popularized detection-as-code and the security data lake, and its pending Databricks acquisition signals the convergence of SIEM and the data lakehouse.
