Single-purpose SIEM software and log management tools provide valuable security information, but often require expensive and time-consuming integration efforts to bring in log files from disparate sources such as asset inventory, vulnerability assessment, and IDS products. Once you have the data, you then must research and write correlation rules to identify threats in your environment. These challenges multiply as you migrate workloads and services from on-premises infrastructure to public cloud environments.
For today’s resource-strapped IT teams, the time and expense required to deploy a SIEM seriously delays their time to threat detection, and thus, return on investment.
