SIEM (Security Information and Event Management) tools are an integral part of IT setups supporting critical business operations in today’s digital economy. The term SIEM is a combination of the following two practices in network and security management:
- SEM (Security Event Management) – log analysis and event correlation (often in real-time) to counter security threats and incidents
- SIM (Security Information Management) – log collection, management, and reporting for internal audits or compliance purposes
It’s important to note SIEM tools and practices have evolved significantly over the last decade to improve proactiveness in incident response. Today many of the advanced SIEM tools employ machine learning algorithms or predictive statistical analysis to analyze more data in a quick time. These tools simplify IT administration by not only offering granular visibility into enterprise environments but also actionable intelligence in place of an endless stream of logs and alerts. In this article, we’ll list top SIEM tools in the market.

How to Select the Best SIEM Tool for Your Organization
So, which of the tools mentioned above is best for your organization? In addition to considering your organization’s budget, you need to factor in a myriad of technical parameters for assessing your organization’s infrastructure readiness for implementation. No two organizations have the same set of requirements. Even for same-sized organizations, the log management and compliance reporting needs may differ depending on their geography and industry vertical. Further, some organizations may choose a SIEM tool entirely for meeting their compliance needs, while others would like these tools to supplement their security.
Based on these parameters, you can decide whether you need a tool with stunning visual dashboards and advanced real-time analytics or would want to work with more economical options offering reports to meet audit requirements. In the end, you would like to strike the right balance and shortlist products delivering better ease of management, quicker results, easier integration with your existing setup, and a lower total cost of ownership.
