Computer security is one of the major challenges of modern society. As more people, businesses, and institutions rely on computer systems, the need to protect them from theft, damage, or disruption has also greatly increased.
Security information and event management (SIEM) is a field under computer security. SIEM tools are not a new addition to the computer or IT security market. The technology existed for more than 10 years starting with simple collection and storage of log messages and audit trails. In the past, most users were large organizations and public companies who used an on-premise SIEM solution primarily for the purpose of IT compliance to regulations such as HIPAA and SOX rather than data security.
What are SIEM tools and software?
Computer security vendors offer SIEM technology as software, hardware, service, or a combination of all. SIEM software and tools come in various configurations and capabilities. Typical features include log management, long-term storage of log messages, analysis and reporting of log data, real-time monitoring, event correlation, notifications, and incident response. The best SIEM tools are able to do two important functions: to provide reports on security-related incidents and events, and send alerts if its analysis indicates the presence of a potential security issue.
SIEM solution trends
Security consulting firms estimate that the impact of different security breaches worldwide range in the tens to hundreds of billion dollars, and this is only from publicly reported data. Today, demand for greater IT security is driving companies and organizations of all sizes to put in place a SIEM solution. This is now more critical with distributed teams and remote work. Although on-premise solutions are preferred by large enterprises due to the sensitivity of data, hybrid deployment and as-a-service models are also increasing because of the benefits of running analytics on the cloud as well as flexible pricing for SMBs.
Best SIEM tools & software
Today’s SIEM software vendors are offering newer capabilities in their products. Aside from data aggregation, retention, correlation, and alerting, the best SIEM tools also offer dashboards to help users see patterns or anomalies, as well as forensic analysis to cross-search from different nodes and time periods. Some are also introducing threat intelligence, machine learning, advanced statistical analysis, AI, and deep learning capabilities. Below is a list of SIEM tools and software that we have compiled in no particular order. We’ve based it on reviews from multiple sites, features, support, and company ranking.
