About Exabeam

Exabeam sells security operations software for threat detection, investigation and response (TDIR), including cloud-native SIEM, behavioral analytics and an on-premises SIEM platform.[9]

Exabeam says AI agents now act alongside human employees, often at machine speed and massive scale, and that traditional security tools were not built to see or understand this behavior. Exabeam says it applies behavioral analytics to both humans and AI agents to help organizations detect signals of compromised credentials, malicious activity and misaligned autonomous systems earlier. User and entity behavior analytics (UEBA) and Agent Behavior Analytics (ABA) automatically baseline activity and expose anomalies.[10]

New-Scale Fusion is the cloud-native platform. New-Scale Fusion combines New-Scale SIEM and New-Scale Analytics in a modular platform that unifies log management, behavioral analytics, dynamic risk scoring and automation. Exabeam says New-Scale Fusion can be deployed to replace an existing SIEM or to augment current tools with behavioral analytics and automation. New-Scale Fusion runs on Google Cloud Platform (GCP) with a 99.5% uptime SLA, and customers select a hosting region at purchase.[1][9][14]

New-Scale SIEM combines fast search, advanced correlation and persistent AI co-investigation in a unified TDIR workbench. Exabeam Nova is a platform-wide co-investigator that follows analysts through Threat Center, search timelines and Outcomes Navigator. Threat Center unifies alerts, cases, detections and watchlists in one workbench.[1][9]

On data handling, Exabeam says prebuilt collectors process more than 2 million events per second (EPS) and that customers can start with 7,000+ prebuilt log parsers. The Common Information Model (CIM) normalizes data at ingestion. The Exabeam Threat Intelligence Service ingests and scores commercial and open-source threat feeds, updates every 24 hours, and is included at no extra cost.[9]

LogRhythm SIEM is deployed on-premises for complete data control. LogRhythm SIEM includes 1,100+ prebuilt correlation rules mapped to MITRE ATT&CK and compliance mandates. LogRhythm Intelligence applies AI-driven behavioral analytics to surface user and entity anomalies in the LogRhythm SIEM platform, and it is an add-on to LogRhythm SIEM rather than a standalone product. NetMon monitors network traffic for LogRhythm or New-Scale Security Operations Platform deployments.[11][12][13]

Exabeam names Resorts World Las Vegas, SA Power Networks, MTI Ltd and Port of Antwerp-Bruges among its customers. Exabeam says its platform helps organizations of any size and maturity improve security operations.[3][9][10][13][14]
