SIEM system is a type of security software that collects and analyzes log data from various sources within an organization’s network, including security devices, firewalls, intrusion detection/prevention systems, servers, and other devices. The goal of a SIEM is to provide real-time analysis of security alerts generated by these devices and systems and create reports on security-related information.

Even though SIEM tools are the right tool for event correlation and analytics, it is separate from the SIEM’s core functionality to manage log collection, filtering, distribution, and formatting. Nevertheless, they likely need those other log collection and enrichment features, such as collecting from different types of logs and data sources and parsing or converting log formats. And when the need arises, a mature, well-versed log collection agent, such as NXLog, enters the picture and fills in the gaps between SIEM and the numerous heterogeneous data sources.
