Splunk Inc. announced that Daimler will replace its legacy SIEM with Splunk® Enterprise and Splunk Enterprise Security (ES). The group will use Splunk ES as its nerve center for security analytics to gain security insights across the entire organization, including business critical environments such as vehicle systems and manufacturing lines. The company chose Splunk over open source alternatives as part of its strategy to buy best-of-breed solutions rather than build things in house.
