Datadog Cloud SIEM extends security signal retention to 15 months at no cost
What happened
Between the Oct 5, 2026 and Oct 12, 2026 captures of Datadog's pricing page, Pulse recorded one change: Cloud SIEM security signal retention extended from 12 to 15 months at no additional cost; security logs remain indexed for 12 months. Pulse files it as a packaging change (limit increase) with an upward direction. Pulse's latest capture (Nov 2, 2026) lists Cloud SIEM at $5 and Cloud SIEM On-Demand at $7.50.
It lands 7 days after Datadog's previous change, "Datadog Cloud Siem makes workflows free when triggered by security findings" (Oct 5, 2026). Before that Pulse recorded "Datadog Cloud Siem: free investigation allotment metric changed to per-TB" (Jul 27, 2026). Datadog has been tracked since 2023-11-14.
In the same window Dynatrace, Elastic, Grafana, Sumologic and Splunk also changed their Cloud & DevOps pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
