What is SIEM in cybersecurity?

SIEM (Security Information and Event Management) software is an advanced technology that combines SEM (Security Event Management) and SIM (Security Information Management) disciplines. Thus, SIEM is able to offer a single platform to cybersecurity professionals where they track activities in their IT setup. The strongest suit of SIEM is its ability to offer real-time tracking, log analysis, threat detection, and incident response. That is why it is a must for enterprises that take cybersecurity seriously.

How does SIEM solution work?

SIEM software first collects data generated by the entire technology infrastructure of the organization, then it processes this data. SIEM is able to gather log data from various devices, systems, and apps like antivirus software and firewall in a network. After the aggregation process, SIEM analyses great amounts of data in context of threat intelligence and advanced analytics. Then it generates alerts for security teams and provides detailed reports for security events and incidents. This way, SIEM offers advanced event management capabilities and reduces the time wasted by false positives.

What is SIEM used for?

SIEM has a wide range of use cases including but not limited to security event detection and management, compliance and regulation processes, detection and prevention of insider threats, IoT (Internet of Things) security.

Why is SIEM required?

Each and every single day, the IT infrastructure of your organization produces massive amounts of data. Aggregating and processing this data while also keeping an eye on the security alerts is inefficient, if not impossible. Offering a potent and easy-to-use dashboard, SIEM aggregates log data from all sources in real-time and allows cybersecurity professionals to analyse this data within context and mitigate incidents.


As a very potent tool, SIEM is able to identify suspicious activity, detect security incidents and trigger alerts yet responding these alerts is rather a manual and repetitive task. SOAR, on the other hand, integrates tools and apps to automate such tasks while unifying teams, processes and various tools. In addition, SOAR minimizes response time by coordinating people and teams while offering them an efficient space that allows prioritizing security events and gathering know-how. Thus, SOAR allows security teams to focus on high-risk alerts, instead of mundane low-risk alerts.

What is the difference between SIEM and SOC?

Consisting of people, processes and technology, SOC (Security Operations Centre) is a hub that does network monitoring, threat detection and incident response. In order to function and keep up with these processes, SOC relies on tools like SIEM for visibility into the network. SIEM assists SOC by creating alerts and giving contextual information to cut down response time.
