SIEM vs. Next-Gen SIEM Comparison*
At first glance, a Threat Detection & Response tool may look like a SIEM. Both take in telemetry from across an organization’s security stack to better detect threats. What they do with that data varies widely.
| SIEM | Next-Gen SIEM/Threat Detection & Response | |
|---|---|---|
| Primary Use Case | Collect and analyze log data from various security systems and devices for correlation. | Combine endpoint, network and cloud data to detect, investigate and respond to threats. |
| Data Sources | Primarily focuses on log data from security devices, applications, and infrastructure. | Collects data from endpoints, networks, cloud environments and other security solutions, along with infrastructure and applications. |
| Threat Detection | Often lack context needed to detect patterns and understand threat severity, impeding security team’s ability to prioritize investigation and response. | A blend of threat detection techniques, including signatures, threat intel, behavioral analysis and machine learning/AI-powered analytics for superior incident correlation and advanced threat detection. |
| Incident Investigation | Security teams manually investigate incidents by correlating events from multiple sources. | Provides a unified analyst-centric platform, with rich contextual data and investigative and analytical tools, to investigate incidents, correlate data and respond to threats. |
| Incident Response | Limited automation capabilities; relies on manual response actions or third-party integrations. | Automated response actions, such as isolating compromised devices, based on detected threats. |
| Scalability | May struggle with high volume and variety of log data, leading to excessive noise and false positives. | Designed to handle massive volumes of data in a hyper-scalable, cloud-based data lake, with nothing to deploy. |
| Visibility | Limited to the logs and data collected from SIEM-connected sources, resulting in blind spots that limit ability to detect threats. | Comprehensive visibility into endpoints, including IT, OT, IoT and IoMT, along with networks and cloud environments. |
| Ecosystem Integration | Typically integrates with a wide range of security tools to collect and correlate log data. | Integrates with other security solutions for improved threat detection, response and visibility. |
Every next-gen SIEM is different. Forescout Threat Detection & Response combines vendor- and EDR-agnostic support for 180+ data sources with predictable, endpoint-based pricing; automated data normalization and enrichment; 1,500+ verified rules and models; and a two-stage threat detection engine to weed out false positives and identify true threats.
