What Graylog does
Graylog is a Houston-headquartered (originally Hamburg-founded, around 2010-2012) cybersecurity software company that provides centralized log management and Security Information and Event Management (SIEM) targeted at lean and mid-market security teams rather than large enterprise SOCs. Its platform collects, stores, searches, and analyzes log data across hybrid environments, combining log management with threat detection, automated correlation, risk scoring, and incident response in a single product line.
The product portfolio is structured as a platform with editions and add-on modules: Graylog Security (the SIEM tier), Graylog Enterprise (centralized log management), Graylog Open (a source-available free edition driving bottom-up adoption), Graylog Cloud (managed SaaS deployment), Graylog Illuminate (pre-built Sigma rules and MITRE ATT&CK content), Graylog Small Business, and Graylog API Security (acquired from Resurface.io in July 2023). Recent releases (v7.0 in Fall 2025 and v7.1 in Spring 2026) embed explainable AI features including threat prioritization, automated investigation workflows, an AI assistant called Arti, and a Model Context Protocol (MCP) Server for connecting LLMs to Graylog telemetry.
The company makes money primarily through annual subscription contracts priced by capacity or seats across Security, Enterprise, Cloud, and API Security tiers, with professional services layered on for enterprise and mid-market customers. Its go-to-market combines a direct enterprise sales motion, a self-serve product-led growth funnel through Graylog Open and graylog.org, an AWS Marketplace listing with native AWS Security Hub and Amazon Security Data Lake integrations, and channel partnerships such as the Invisinet Zero Trust Platform embed. The company is privately held, has 101-250 employees, and is backed by Harbert Growth Partners, Silver Lake Waterman, Piper Sandler Merchant Banking, and earlier investors, with named enterprise customers spanning DHL, Deloitte, Schneider Electric, SAIC, Siemens, Sunoco, L'Oréal, Vodafone, UCSF, Deutsche Bahn, Leidos, and Kaizen Gaming.
