Graylog
Graylog is a log management and security information and event management (SIEM) company founded in 2009.
Profile
Graylog provides software that collects, analyzes, and stores machine log data for security monitoring and IT operations, helping teams detect threats and troubleshoot issues.
Graylog is a log management and security information and event management (SIEM) company founded in 2009. As of mid-2026, the company markets itself as 'The SIEM for Lean Teams,' emphasizing cost efficiency and flexibility by offering deployment across its own cloud, customer clouds, or on-premises. The company's most recent disclosed funding round was in October 2023, when it raised $9 million in equity and $30 million in debt, as reported by TechCrunch.
Graylog's customer base includes large enterprises such as DHL, Deloitte, Schneider Electric, SAIC, Siemens, Sunoco, L'Oréal, Vodafone, UCSF, Deutsche Bahn, and Leidos, as displayed on its website. The company's product, Graylog 7.1, was released in spring 2026, featuring new anomaly detectors and alert fatigue reduction tools. Graylog was also recognized in the 2026 Gartner SIEM Voice of the Customer report, with 86% of reviewers recommending the product.
The company's financial trajectory is not publicly disclosed as a private entity, but its 2023 debt and equity raise suggests a focus on growth and product development. A notable risk is the potential for confusion with Gray Television (NYSE: GTN), a completely unrelated media company, which has its own financial results and SEC filings. Graylog's competitive position in the SIEM market is challenged by larger vendors like Splunk and Microsoft, and its reliance on a lean-team messaging may limit appeal to very large enterprises with complex security operations centers.

Strengths and what to watch
Strengths
- Offers flexible deployment options (cloud, customer cloud, on-premises), which appeals to organizations with strict data residency requirements
- Pricing model avoids per-ingestion licensing spikes, making long-term log retention more predictable for budget-constrained teams
- Product roadmap shows consistent feature releases, with the spring 2026 7.1 release adding anomaly detection and alert fatigue improvements
Watch for
- Graylog is a private company with no disclosed revenue or headcount, making it difficult to assess financial health or growth trajectory relative to public competitors
- The company's brand name overlaps with Gray Television (NYSE: GTN), a publicly traded media conglomerate, which can cause confusion in search results and financial data aggregation
- The SIEM market is dominated by Splunk, Microsoft Sentinel, and Palo Alto Networks; Graylog's 'lean team' positioning may struggle to win large, complex enterprise deals
