1Security Monitoring Tool vs TEHTRIS SIEM: 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.

TEHTRIS SIEM

Mid-market and enterprise security teams that need log collection without waiting for vendor-specific integrations should start with TEHTRIS SIEM; its support for seven log formats out of the box plus native connectors to AWS, Office 365, and Zscaler means you're correlating data within days, not weeks. The platform's 500+ built-in correlation rules and tight integration with TEHTRIS XDR AI PLATFORM and SOAR give you detection and automated response in one stack, addressing the full arc from DE.CM through RS.MA in NIST CSF 2.0. Skip this if your priority is long-term forensic retention beyond six months or if you need best-of-breed point tools; TEHTRIS SIEM optimizes for speed and orchestration, not archival depth.
