SIEM Tools
During my cybersecurity reskilling journey, I had the opportunity to work with and learn several key SIEM tools that are essential for modern security operations. Each of these tools provided unique insights and capabilities, helping me to better understand how to detect, analyse, and respond to potential security threats. In this blog, I’ll share my experiences with some of the most impactful SIEM solutions I’ve used, including Splunk, IBM QRadar, Microsoft Sentinel, and Wazuh.

Splunk
Splunk is a versatile SIEM tool known for its powerful log management and analysis capabilities. It excels at gathering and indexing data from a wide range of sources, including applications, servers, and networks. Splunk’s ability to correlate data across different platforms and visualise it in real-time dashboards makes it a favorite among security professionals. With its extensive app ecosystem, users can tailor their Splunk environment to meet specific security needs, such as threat detection and incident response.

IBM QRadar
IBM QRadar is a leading SIEM solution that integrates seamlessly with existing infrastructure to provide real-time visibility into threats and vulnerabilities. QRadar excels at identifying and prioritising security incidents by analysing log data, network flows, and user behaviour. It leverages artificial intelligence to automate threat detection and response, reducing the time it takes to investigate incidents. This makes QRadar a valuable tool for organisations looking to enhance their security operations with minimal manual intervention.
