Panther is an AI SOC platform for security teams that ingests and normalizes security logs, detects threats, and supports alert investigation and response. Panther AI can query a data lake, review detection logic and alert history, gather context from connected tools, resolve noisy alerts, and escalate high-confidence threats. Its AI Detection Builder turns plain-language threat descriptions into Python detections. Teams can write, test, and version custom rules through CI/CD and GitHub code review, using PantherFlow and SQL. Snowflake or Databricks can serve as the security data lake while data remains in the customer’s warehouse. Integrations include AWS CloudTrail, Okta, GitHub, Slack, CrowdStrike, Databricks, and PagerDuty; MCP connections include Slack, PagerDuty, Notion, GitHub, and Atlassian. Deployment is available as managed SaaS or Cloud Connected. Panther provides a REST API and states that data is isolated in dedicated instances with 99.9% SLA-backed uptime.
