Sumo Logic Cloud SIEM vs Splunk Enterprise Security

The two vendors now meter different things. Sumo Logic's Flex model charges nothing to ingest and index, and consumes credits against the volume a query scans plus storage, so cost tracks how hard the team searches rather than how much it collects. Splunk Workload Pricing still ties cost to ingest and compute. That makes Sumo Logic the better fit for a high-volume, low-query estate and for teams splitting observability and security spend in one contract, and Splunk the better fit where deep content and constant querying are the point. Neither publishes a unit price, so both numbers come out of a quote.
