NAN SIEM Services vs TEHTRIS SIEM: Side-by-Side Comparison (2026)

NAN SIEM Services

Mid-market and enterprise security teams without in-house SOC capacity should pick NAN SIEM Services for its managed 24x7 monitoring and incident response built into the platform itself, not bolted on as an add-on. The vendor covers four of five NIST RS (Response) functions directly through staffed incident analysis and mitigation, which means you're buying detection and human response as a unit. Skip this if your team has mature internal analysts and threat hunting capabilities; you'll pay for SOC services you don't need.

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.
