Technological innovation is reshaping various aspects of our lives. It has not only provided prosperity but also given birth to new challenges, such as cyber threats. A pertinent tool that can be used to mitigate cyber threats is Security Information and Event Management (SIEM) software.
The need for SIEM software is increasingly becoming a cornerstone in the cybersecurity world. SIEM systems help in collecting and storing, analyzing, and reporting on log data for Incident response, forensics, and regulatory compliance. However, not all organizations have the budget for expensive SIEM software. Thankfully, there's a wide range of free SIEM software available in today's market, giving enterprises the protection they need without a financial strain.
In 2022, multiple free SIEM software stand out, offering robust features at no cost.
