Scanner
Scanner is a San Francisco cybersecurity company that turns the log data companies already dump into Amazon S3 into a fast, searchable security data lake. Instead of paying traditional SIEM prices to keep only a few weeks of logs, security teams use Scanner to index petabytes of data directly in object storage, run continuous threat detections, and search years of history in seconds - now increasingly driven by AI agents. Founded by ex-Cisco and Dropbox engineers Cliff Crosland and Steven Wu, the company raised a $22M Series A led by Sequoia Capital in March 2026.
Panther
Panther is a cloud-native SIEM and AI SOC platform that helps modern security teams detect, investigate, and respond to threats at cloud scale using Python-based detection-as-code and a serverless security data lake.
