The number of tools for IT Ops professionals to choose from is overwhelming. For this reason, we created the periodic table of IT Ops tools to better define, organize, and explain the IT Ops tooling landscape. It is our hope that it will help IT professionals find, explore, and choose tools for their future IT Ops stack.

In a portion of this table we dive into Security Information Event Management (SIEM) tools specifically. Below you will find a list of the top security information and event management tools per the interactions we measure on the table.

What is SIEM?

Security information and event management (SIEM) is an approach to security management that combines SIM (security information management) and SEM (security event management) functions into one security management system. The acronym SIEM is pronounced "sim" with a silent e. The underlying principles of every SIEM system is to aggregate relevant data from multiple sources, identify deviations from the norm and take appropriate action. At the most basic level, a SIEM system can be rules-based or employ a statistical correlation engine to establish relationships between event log entries. Advanced SIEMs have evolved to include user and entity behavior analytics (UEBA) and security orchestration and automated response (SOAR).
