What major benefit does FortiSIEM offer by cross-correlating data from traditionally isolated sources?

FortiSIEM's capability to cross-correlate data from traditionally isolated sources offers significant advantages in enhancing threat identification. By integrating information from various security tools, network devices, applications, and systems, FortiSIEM creates a holistic view of the environment. This unified perspective allows for more accurate detection of security incidents that may not have been evident when analyzing data in silos.

For example, if an unusual activity is noted on a firewall but is dismissed as benign without considering related logs from an intrusion detection system or end-user behavior analytics, a potential threat could be overlooked. The cross-correlation of data points—such as user access logs, changes in configuration, and threat intelligence feeds—enables security teams to uncover patterns or anomalies indicative of a security breach, leading to a faster and more effective response.

This comprehensive visibility is critical in today’s complex threat landscape, where attackers use sophisticated methods that may span multiple attack vectors and systems. Improved threat identification through FortiSIEM allows organizations to better protect their assets and respond to incidents proactively.
