Sumo Logic pricing in 2026: the Flex model, credits, and real spend

Sumo Logic's current go-forward pricing is the Flex model, and it inverts the usual SIEM economics. Ingesting and indexing log data is free. You do not pay a per-GB ingest charge, and you do not manage or rehydrate storage yourself. Instead, credits are consumed by two things: the volume of data you search (scan) and the volume you store. Sumo describes this as paying for analytics and insights, not data management.

A credit is the unit of consumption, with an MSRP of $1.50 for Enterprise Suite Flex on US annual terms, plus published uplifts of 10 to 40 percent by deployment region and up to 30 percent by payment terms, and a default 10 percent increase in net annual fees at renewal unless agreed otherwise in writing. Because ingest is free under Flex, the cost lever moves from how much data you collect to how much of it you actually query and how long you retain it. This is a genuine structural difference from ingest-metered vendors, and it is why a Sumo Flex bill cannot be reconstructed from a GB-per-day figure alone.

The one important exception to free ingest is Cloud SIEM. The CSE GB Ingest variable burns 40 credits per GB, which at the $1.50 Flex MSRP is about $60 per GB: 5 GB per day of Cloud SIEM ingest is 73,000 credits, or about $109,500 a year, before discount. Cloud SIEM Enterprise is an additional purchase on top of the base plan. So a security deployment has two cost drivers that a pure observability deployment does not: the Cloud SIEM ingest stream, and the search volume that detections and investigations generate.

Search cost under Flex is set by two published burn rates, not by data tier. Flex Log Upfront Search burns 10 credits per GB scanned (about $15 at MSRP) against the search capacity you buy upfront; once that is used, Flex Log Metered Search burns 20 credits per GB scanned (about $30) until you add more upfront capacity. The Continuous, Frequent and Infrequent tiers belong to the Cloud Flex Credit plans, where ingest is what burns credits (25, 12 and 5 credits per GB) and Infrequent data adds a 2-credit charge per GB scanned. That makes Infrequent on a Cloud Flex Credit plan the cheap home for compliance logs and other keep-but-rarely-read data.

Storage also consumes credits, at 0.05 credits per GB stored per day on both schemes, so retention is a real cost dimension even though Flex ingest is free: at the Flex MSRP that is about $2.28 per GB-month. The practical discipline under Flex is to watch scan behaviour and retention rather than ingest. Sumo's Account Overview page reports credit consumption for Flex data searches, which is the metric to monitor day one, since broad wildcard scans across large volumes are the fastest way to burn credits.

Sumo Logic earns its place in three buyer profiles. First, organisations that ingest a lot but search selectively and keep short retention, where the free-ingest Flex model directly rewards the way they actually work. Second, teams with high-volume compliance retention on a Cloud Flex Credit plan, where routing rarely-read logs to the Infrequent tier costs 5 credits per GB ingested plus 2 credits per GB scanned, rather than 25 credits per GB for Continuous. Third, teams leaving an ingest-metered vendor because collection volume, not query volume, was driving the bill; moving the cost basis to scan and storage can materially lower total spend for that profile.

Sumo is the weaker pick for two profiles. First, teams that run broad, constant scans across all of their data, or keep long retention on Flex, where the free-ingest advantage erodes because Flex search (10 to 20 credits per GB scanned) and storage (0.05 credits per GB per day) are what you pay for. Second, Microsoft-heavy shops whose log mix is dominated by Microsoft 365 and Azure sources, where Sentinel's free Microsoft 365 ingest and native Entra ID integration can make Sentinel structurally cheaper for that data. Sumo competes with Sentinel on non-Microsoft sources but cannot match the bundled-Microsoft economics.

Against Splunk specifically, the comparison turns on metering rather than a headline discount. A Splunk Cloud deployment at 50 GB/day lists at about $63K base and about $124K with Enterprise Security. At Sumo's published list rates, 50 GB/day with 30-day retention and 5 GB/day through Cloud SIEM comes to about $128K on Enterprise Suite Cloud Flex Credits and $219K to $424K on Flex at MSRP, so Sumo does not undercut Splunk at list on these assumptions. Negotiated Sumo terms and your real scan volume can move that a long way, so model your real query patterns before assuming a saving in either direction.
