Gold: Splunk Enterprise, Splunk Inc.
Splunk's flagship SIEM system, a security tool for machine-generated big data, received top scores across the board. Splunk Enterprise collects machine-generated data to provide threat detection, log management and analytics through its Splunk App for Enterprise Security software, which includes pre-defined templates, dashboards and reporting tools. Splunk indexes ACSII text, using up to 150 commands, to offer statistical analysis and visualizations through its dashboards, which received high marks from readers.
The SIEM software also scored well in granular and flexible policy definition, data archiving and event correlation. Splunk received high marks for the technology's integration and compatibility with existing systems, devices and applications. The system does not natively handle binary data but Hadoop and other converters are available.
Overall, readers were pleased with their return on investment, as well as the vendor support and services. The latest version, Splunk Enterprise 5.0, adds report acceleration, PDF generation, parallel indexing and enhanced dashboard functionality. To use Splunk, security teams need to understand Unix shell scripting commands, SQL and have adequate documentation about their organization's data fields.
