This solution brief explains how Securonix Unified Defense SIEM uses a single-tier “security data cloud” built on Snowflake to address traditional SIEM limits in scale, performance, and retention. Instead of hot-warm-cold tiers that require rehydrating archived data, it keeps up to 365 days of data “hot” and searchable to speed hunts and investigations and reduce operational workarounds. Consolidating cloud and on-prem data into one store supports real-time analytics, machine learning, enrichment, and threat chain analytics mapped to frameworks like MITRE ATT&CK and US-CERT, improving signal quality and response. The brief also highlights ATS for retroactive hunting and SOAR workflow efficiency using the same data.
