XIEM
Extended Security Incident and Event Management
Erweitertes Sicherheitsvorfall- und Ereignis-Management
XIEM® is the tiered managed-security operating model from NEOSEC and a registered trademark of NEOSEC GmbH. It extends classic Security Information and Event Management (SIEM) — the central collection, normalisation and correlation of security-relevant events — with endpoint forensics, network visibility and deception technology, and consolidates them into three building tiers: Sentry, Orchestrate and Command. The guiding idea is end-to-end visibility from detection through to defensible response, without an organisation having to build its own 24/7 capability.
History. The term Security Information and Event Management (SIEM) was coined in 2005 by the analyst firm Gartner, merging the previously separate disciplines of Security Information Management and Security Event Management. Over the following two decades a recurring gap emerged: a SIEM sees events but, on its own, provides neither forensic depth at the endpoint nor a rehearsed response chain. XIEM (Extended SIEM) is NEOSEC's answer — not a new market product but a consolidated operating model that brings detection and response together under one roof.
Facts. XIEM is structured in three tiers. Sentry forms the foundation: Security Information and Event Management (SIEM) correlation, forensic endpoint telemetry (Endpoint Detection and Response (EDR) function), network security monitoring (Network Detection and Response (NDR)/NSM function) and decoy/deception systems. Orchestrate includes every Sentry capability and adds Managed Detection and Response (MDR) — supervised, active detection with initiated countermeasures. Command, finally, includes every Orchestrate capability and runs it through a 24/7 Security Operations Center (SOC). Each tier is a genuine superset of the one below it.
Outlook & recommendation. Under Network and Information Security Directive 2 (NIS2) and Digital Operational Resilience Act (DORA), continuous detection, the ability to report within tight deadlines and demonstrable response are no longer optional but mandatory. For mid-sized organisations without their own Security Operations Center (SOC), the decisive question is rarely „which tool“ but „who runs it verifiably and responds at three in the morning“. That is precisely where the tiered XIEM model fits: entry via Sentry, expansion to Orchestrate and Command along real maturity. NEOSEC (neosec.eu) positions XIEM explicitly as the path from mere visibility to provable capacity to act.
