1Security Monitoring Tool vs sysmon-modular: Side-by-Side Comparison (2026)

1Security Monitoring Tool

Mid-market and enterprise teams managing Microsoft 365 environments need visibility into user behavior anomalies and permission changes that native Microsoft tools leave blind, and 1Security Monitoring Tool delivers that through continuous activity monitoring across Entra ID, Exchange, SharePoint, and OneDrive with real-time alerting on suspicious patterns. The tool covers NIST DE.CM and DE.AE functions effectively, meaning you get detection and analysis of anomalies in place, though incident response orchestration remains your responsibility. Skip this if your organization runs minimal Microsoft 365 usage or lacks the analyst capacity to act on behavioral alerts; the tool surfaces problems but doesn't automate remediation.

sysmon-modular

Security operations teams building Windows detection infrastructure on tight budgets should adopt sysmon-modular for its pre-built, community-maintained Sysmon rulesets that eliminate weeks of tuning work. With nearly 3,000 GitHub stars and active maintainers shipping modular configs for process creation, network activity, and registry changes, you're inheriting battle-tested detection logic rather than starting from scratch. This is free software that trades vendor support for a self-service model, so skip it if your team needs commercial SLA backing or can't maintain a homegrown Sysmon pipeline.
