Security information and event management (SIEM) is a security tool designed to detect, respond , and manage security threats in real time by collecting and analyzing log data from across your entire IT environment, such as servers, endpoints, applications, and network devices.

Evolution of SIEM

The SIEM’s evolution reflects the shift of  cybersecurity landscape’s  from reactive to proactive threat management.The evolution of SIEM is illustrated below:

SIEM has evolved across decades-decades to address escalating cyber threats, compliance requirements, and data explosion, progressing through generations from basic log aggregation to AI-enhanced platforms integrated with SOAR for automated response.The phases of evolution of SIEM are as explained below:

How SIEM Works: 7 Pillars of Modern SIEM Architecture

In the evolving cybersecurity landscape, SIEM (Security Information and Event Management) serves as the central nervous system for threat detection and response.
The SIEM works based on the following SIEM Architecture:

Best Practices for SIEM Implementation

Successful SIEM implementation requires a proper strategic planning to maximize threat detection while minimizing operational overhead. The key practices needed to be followed for SIEM implementation are as follows:

What is Cloud SIEM?

Cloud SIEM (Security Information and Event Management) or SIEM-as-a-Service or SIEM Saas is a cloud-delivered solution which offers comprehensive visibility across distributed workloads in distributed environments, enabling real-time monitoring, threat detection, and faster incident response. Through cloud-based dashboard it analyzes log data from diverse sources such as endpoints, networks, and cloud workloads

The Cloud SIEM provides below mentioned benefits over the traditional SIEMs.
