Graylog

Graylog sells centralized log management and SIEM software for lean security, IT and audit teams. The site says the product began in 2009 as an open-source log management project, and lists headquarters in Houston, Texas, with offices in London and Hamburg.

The platform covers log collection, search, data pipeline routing with a built-in data lake and policy-driven retention. Graylog Security adds risk-scored alerts grouped into incidents by the Verascend Incident System, automated investigations and an AI report-writing agent. Customers named include DHL, Siemens, Vodafone and Lockheed Martin.

• Log management: centralized collection, search and policy-driven retention tiering.
• Data pipeline: routing with a built-in data lake.
• Incident system: Verascend groups risk-scored alerts into verified incidents.
• Automated investigations: related events and timelines collected automatically.
• AI reporting: an agent drafts incident documentation with explainable evidence.
• Detection content: prebuilt content for common sources, attack frameworks and audit standards.

A Vietnamese bank or insurer can centralize server and application logs for audit and incident review. A mid-size enterprise security team can use Graylog Security as a lighter SIEM. An IT team can start with Graylog Open for log search before upgrading.

Centralized logs support both IT operations and security or audit use cases in one product. Graylog Open is a free, self-managed edition, and the paid editions can run in cloud, on customer infrastructure or air-gapped sites. AI findings show the evidence behind them, which supports audit review. The site cites 60,000+ installations.

Organizations need centralized logging for both operations and compliance, while SIEM costs push lean teams toward lighter alternatives. AI-assisted triage is being added to reduce alert fatigue. In Vietnam, banks and enterprises under cybersecurity and data regulations need auditable log retention.
