SIEM retention cost modeler

You set GB/day and retention months. You get an annual retention-loaded cost per vendor that publishes a unit price. Vendors that publish none return Quote rather than a modelled number.

Microsoft Sentinel (Analytics)$784,750
Microsoft Sentinel (Basic Logs)$182,500
Elastic Serverless ingest$155,125
Graylog Cloud Security$273,750
Snowflake lake only$219,000
Google Chronicle (12 months hot retention bundled)Quote
Sumo Logic Cloud SIEM (Flex)Quote

PCI-DSS (1 year) and HIPAA (6 years)

For PCI-DSS at 12 months Chronicle removes the retention line item altogether, because all three Google SecOps packages bundle 12 months of hot retention; Google publishes no rate, so the size of that saving only comes out of a quote. For HIPAA at 72 months Elastic Serverless plus self-managed cold tier or Snowflake lake-only with a detection layer beats any per-GB SIEM with a per-month archive line item.
