Top 20 Free and Open Source SIEM Tools with Freemium Options

What is Open-source code?

Open-source code, also referred to as open-source software or simply open source, is a type of software that is distributed with a license that allows anyone to view, use, modify, and distribute its underlying source code. In other words, open-source code is made freely available to the public, encouraging collaboration, transparency, and community-driven development. This approach stands in contrast to proprietary or closed-source software, which keeps its source code private and restricts access to only the compiled executable version of the program.

Open-source software is typically developed and maintained by a community of volunteers or organizations who work collectively to improve the software. This collaborative and open nature has led to the creation of a wide range of applications, from operating systems like Linux to web browsers like Mozilla Firefox and productivity suites like LibreOffice. The open-source philosophy promotes innovation, peer review, and the sharing of knowledge, fostering a culture of accessibility and inclusivity in the world of software development. This has made open source a vital part of the modern technological landscape, contributing to a vast array of solutions across various domains and industries.

What is a SIEM tool ?

A Security Information and Event Management (SIEM) tool is a comprehensive cybersecurity solution designed to help organizations manage and analyze the vast amount of data generated by their IT infrastructure and security systems. SIEM tools collect, correlate, and analyze data from various sources, such as network devices, servers, applications, and security appliances, to provide real-time insights into an organization’s security posture. By monitoring and alerting on potential security incidents, SIEM tools play a crucial role in threat detection, incident response, and compliance management. They help organizations identify and respond to security threats, comply with regulatory requirements, and improve overall cybersecurity effectiveness by providing a centralized platform for security monitoring and analysis.

Here are 20 SIEM (Security Information and Event Management) tools that are available for free, as freemium, or open source:
