What is Security Information and Event Management?

Security analysts need to address the most critical threats facing their organization. Since 2005 when analyst firm Gartner coined the term, Security Information and Event Management (SIEM) has grown in importance for organizations looking to improve their security posture.

Today’s SIEM has evolved to incorporate advanced analytics such as user behavior analytics (UEBA), network flow insights, artificial intelligence (AI) and incident forensics. With a single dashboard, security analysts can gain insights from this data, drawn from a large range of security sources, to prioritize mitigation efforts based on risk profiles and increase efficiency.

How customers are using a SIEM

Insider threats

SIEM can help discover insider threat indicators through user behavior analytics and machine learning algorithms.

Phishing attacks

The correlation rules in a SIEM can identify all possible signs of an advanced persistent threat (APT) and detect phishing attacks.

Compliance reporting

SIEM can help your organization comply with standards such as GDPR, PCI, SOX, HIPAA and more.

Data exfiltration

SIEM can use behavioral analysis to correlate seemingly unrelated events, such as insertion of USBs, use of personal email services, unauthorized cloud storage or excessive printing.

OT and IOT security

Correlate data from IT and OT solutions to get a unified view and identify abnormal activity and threats.

Threat hunting

SIEM empowers you to proactively search for malware or attackers that are lurking in your network — and may have been there for some time.
