Security Information and Event Management (SIEM) is a foundational cybersecurity technology that collects, normalizes, and analyzes data from across the organization’s entire IT environment. SIEM tools provide a holistic view of an organization’s security posture and help detect and respond to threats in real-time.
SIEM tools help organizations to identify and address potential security vulnerabilities before they disrupt operations. They also improve incident response and make it easier to meet compliance requirements. As cyberattacks grow more frequent and sophisticated, SIEM has become essential for organizations seeking to reduce dwell time, meet regulatory mandates, and enhance their overall security posture.
We at Expert Insights have gathered a variety of reports and statistics on the subject of SIEM, examining the current markets, the challenges, and the trends shaping the SIEM landscape.
General Market Statistics

- By region, the largest region for the SIEM market is North America, particularly in the US and Canada. The fastest growing region for this market is the Asia-Pacific region, especially India.
NIST’s SIEM Recommendations
As part of their cybersecurity framework for incident response, NIST recommends the following actions which SIEM tools can be used for:
- Use tools to continuously monitor log events for known malicious and suspicious activity and to generate reports on their findings
- Use event correlation technology to gather pieces of related data captured by multiple sources
- Estimate the impact and scope of adverse events through automated and/or manual means, and review and refine the estimate
IDC InfoBrief – The SIEM of Tomorrow
- IDC’s 2024 Worldwide Views of SIEM Survey of 1004 users and managers found that on average, organizations have over 100 data sources connected to their SIEM tool.
- The same survey found that when asked about their top challenges with using the full capabilities of their SIEM platform, the most popular response (32%) was the requirement for dedicated staff.
- When considering a SIEM platform, the most popular response for which features are important (29%) was a real-time detection engine. This was followed closely by connectors to their organization’s data sources (24%) and deployment flexibility (21%).
The State of the SIEM Market report by CrowdStrike and Cribl
- According to IDC’s comparison of SIEM ingestion data of 2021 to 2024, the median volume of data that SIEM tools ingest per day is 3.7TB.
- The same IDC report found that even after evaluating other options, 35% of respondents chose to stay with their current SIEM vendor, suggesting a hesitation towards migrating.
Trends in SIEM – An AI Powered SIEM Future?
As cyber threats become increasingly sophisticated, traditional SIEM approaches often fall short in efficiently processing and analyzing vast amounts of security data. However, newer AI-enhanced solutions are leveraging neural networks to improve threat detection, anomaly detection, and incident response capabilities.
According to Exabeam, these are some of the key capabilities of AI/ML-powered SIEM tools:
- Efficiently aggregate large volumes of information while being able to enrich data with additional context such as threat intelligence
- Machine learning enables advanced pattern recognition for accurately identifying anomalies, learning from past incidents, and predicting future threats
- Automate security alerts and/or incident response actions to address threats quickly
- Significantly cuts down on response times and false positives, freeing resources for human security experts
The average savings for organizations that use security AI and automation extensively to contain data breach was USD 1.76 million compared to organizations that don’t.
The State of the SIEM Market report by CrowdStrike and Cribl
- Legacy SIEM solutions are struggling to expand to more complex or cloud-based environments, ingest larger volumes of data, and perform searches quickly.
- Research from Gartner has found that the average organization works with 10 to 15 security vendors and 60 to 70 tools. This increasing complexity is driving some organizations to consolidate their stack of security tools and use automation where possible. IDC also found that over half of their survey respondents had active consolidation plans.
