Datadog Cloud SIEM: free investigation allotment metric changed to per-TB
What happened
Between the Jul 20, 2026 and Jul 27, 2026 captures of Datadog's pricing page, Pulse recorded one change: Free monthly Bits Security Analyst investigation allotment (100 investigations, min 50) now measured per 1 TB analyzed instead of per 1 billion events. Pulse files it as a packaging change (metric change) with a neutral direction. Pulse's latest capture (Oct 12, 2026) lists Cloud SIEM at $5 and Cloud SIEM On-Demand at $7.5.
It lands 28 days after Datadog's previous change, "Datadog Cloud Siem cuts Cloud SIEM data retention from 15 to 12 months" (Jun 29, 2026). Before that Pulse recorded "Datadog Cloud Siem: billing switched to per-GB, retention cut to 12 months" (Jul 2, 2026). Datadog has been tracked since 2023-11-14.
In the same window Splunk, Grafana, Dynatrace and New Relic also changed their Cloud & DevOps pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
