Graylog

Other B2B Software · Houston, United States · Founded 2009

Graylog, Inc. provides a specialized log management and security analytics software platform, operating from its headquarters in Houston, Texas. The company serves a diverse client base, ranging from individuals and small teams using its open-source product to large enterprises, including those in the cybersecurity, IT operations, and DevOps sectors. Graylog's business model is centered on a freemium approach, offering a free, open-source version called Graylog Open, alongside paid commercial offerings like Graylog Enterprise and Graylog Security, which generate revenue through subscription fees. The company also partners with cloud service providers, resellers, and tech integrators to expand its market reach. The company's journey began in 2009 in Hamburg, Germany, when Systems Architect Lennart Koopmann started a side project named 'Torch' to address the high cost and usability issues he encountered with existing log management solutions. This open-source project aimed to offer a more affordable and efficient way to manage machine data. In 2012, Haas Chapman joined to assist with administration, and by July 2013, both founders left their jobs to dedicate themselves to the project full-time, rebranding it as Graylog. The company, Graylog, Inc., was formally incorporated in the U.S. on December 8, 2014, after Koopmann relocated to Houston. A significant milestone was the launch of its first commercial offering in 2016, making its enterprise product available. More recently, in July 2023, Graylog acquired Resurface.io, a data-driven API security platform, to broaden its security offerings. Graylog's core product is a centralized platform designed to capture, store, and facilitate real-time analysis of vast amounts of machine data. It operates on a three-tier architecture using OpenSearch and MongoDB for scalable storage. The platform provides Security Information and Event Management (SIEM) capabilities, enabling threat detection, security analytics, and incident response. For its commercial users, Graylog offers advanced features such as AI-driven alerting, anomaly detection, and pre-built content for security and compliance through its Illuminate feature. A key differentiator is its integrated approach, which combines log routing, data tiering, and storage management to control costs, avoiding the need for additional tools. With the acquisition of Resurface.io, the company launched Graylog API Security, which integrates with existing security infrastructure to provide a deeper layer of defense against sophisticated API threats by analyzing full request and response data.
