# nxtGuard — SIEM & Security Operations

> Unified security monitoring — log-based detection, file integrity, vulnerability posture, and compliance scanning in one console.

nxtGuard is the NxtSight unified SIEM and security-operations service. Log-based detection, file integrity monitoring, vulnerability posture, and compliance scanning run in a single console, monitored around the clock and mapped to the frameworks your auditors check.
