SIEM (Security Information and Event Management) tools are used by enterprise security teams to secure complex IT environments by collecting, analyzing, and correlating large volumes of data from multiple sources in real-time. These solutions provide comprehensive network observability and threat detection capabilities, but have limitations such as limited data retention, integration challenges, and false positives. Log analytics solutions, on the other hand, collect, aggregate, and normalize log data for analysis, offering enhanced observability of retroactive log data and a more cost-effective choice for exploring historical trends. Combining SIEM and log analytics can help security teams identify potential cyber threats and vulnerabilities, and improve their overall cybersecurity posture.
