Company Overview
About Panther Labs
Panther Labs is a San Francisco-based cybersecurity company founded in 2018 by Jack Naglieri that built a cloud-native Security Information and Event Management (SIEM) platform designed for modern, high-velocity engineering environments. Traditional SIEMs like Splunk and IBM QRadar struggle with scale, cost, and the pace of cloud-native infrastructure — Panther addresses this with a serverless, detection-as-code architecture built on a high-performance data lake.
Business Model & Competitive Advantage
Panther has raised $140M across three rounds — a $120M Series B led by Coatue Management with ICONIQ Growth and Innovation Endeavors — achieving a $1.4B valuation in December 2021. The platform allows security teams to write threat detection rules as Python code, version-control detections in Git, and test them automatically — replacing brittle GUI-based rules with engineering-grade workflows. Its high-scale data lake handles billions of events without the per-GB ingestion cost model that made legacy SIEMs prohibitively expensive. Customers include Snowflake, Dropbox, Zapier, and Snyk. In October 2025, Panther acquired Datable to extend its data enrichment capabilities.
Competitive Landscape 2025–2026
Panther competes with Splunk (now Cisco), CrowdStrike''s Falcon LogScale, SentinelOne''s Singularity platform, and pure-play SIEMs like Exabeam and Securonix. Its detection-as-code differentiation and serverless cost model resonate particularly strongly with cloud-native companies and security teams that operate like software engineering organizations.
