Buyers look past Splunk Enterprise Security when the quote, the Cisco-era contract or the analyst time it assumes is more than the problem needs. Most go to Elastic Security for a search platform with published per-GB rates, to Graylog or Wazuh for a smaller entry cost, or to Microsoft Sentinel when the logs already live in Microsoft 365.
Short answer: The closest replacements for Splunk Enterprise Security in our SIEM software ranking are Elastic Security, Graylog Security and Wazuh. Choose Elastic Security if you like searching logs yourself but want rates you can compute before a sales call. These 11 options are lifted from the Best SIEM Software in 2026 list. The write-ups look at one question, how each one differs from Splunk Enterprise Security, and admit where Splunk Enterprise Security is still ahead.
Visibility in our rankings can be paid for. Payment moves a vendor's position within the shortlist; it never adds a vendor, and it never changes a word of the review or of this page. The first three alternatives go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the established names follow in their ranked order. How it works: placement disclosure · editorial process.
Splunk's pricing page shows start prices for several other products but only a quote button for Enterprise Security. The product is sold in Essentials and Premier editions on activity, workload or ingest pricing, and no trial is listed for it, only a product tour.
Splunk's general terms renew a term for an equal period unless a party gives notice at least 1 day before it ends, though the order can say otherwise. Fees are non-cancelable and non-refundable, so a missed date has a real cost.
Detection Studio, risk-based alerting, SOAR and UEBA reward analysts who tune rules. A company with one IT lead pays for modules it cannot staff. The site now carries Cisco branding and a Cisco copyright line, so the roadmap follows a larger owner.
Rows follow how closely each product can stand in for Splunk Enterprise Security; the closing column is its rank inside our 12-product ranking.

Closest in spirit: a search engine underneath, with prebuilt detection rules and hunting. The meters are public, ingest and retention per GB, and a trial is listed. It offers serverless, hosted and self-managed forms, and egress becomes a charge once the free allowance is used.

Licenses processed volume in the active tier, not devices or users, and a built-in data lake keeps older logs outside the license count. Cloud, on-premises and hybrid are all offered. Sigma rules can be imported from a private repository. It has no SOAR engine as deep as Splunk's.
Switch from Splunk Enterprise Security if a daily-volume license with a free Open edition suits a small SOC.
Graylog Security: complete review · Visit the product page →
Free, open source software built around an agent on each machine, which adds file integrity and configuration checks to log analysis. The company hosts it from a monthly plan, and a 14-day trial is listed. There is no analyst service in the box, so detection tuning stays with you.
Switch from Splunk Enterprise Security if license cost is the blocker and someone on staff can run servers and tune rules.
Needs an Azure subscription and bills for the data you ingest, store and use, with commitment tiers for discounts. Playbooks, UEBA and a Defender portal come built in. It pays off when identity and endpoint logs already sit in Microsoft services, and much less on a Linux estate.
Switch from Splunk Enterprise Security if most of your logs already originate in Microsoft 365 and Azure.
Microsoft Sentinel: complete review · Visit the product page →
A cloud-only service where SIEM is a separately activated product, paid in credits and quoted. Its SOC Analyst Agent investigates alerts and returns a verdict with rationale. It comes from the log analytics side, so one platform can serve both operations and security staff.
Switch from Splunk Enterprise Security if your engineers and your security team want one cloud log platform.
Sumo Logic Cloud SIEM: complete review · Visit the product page →
Formerly Logpoint. Its site promises that data, access and evidence stay under your jurisdiction, with an on-premises option and SIEM, NDR and SOAR modules. It says it avoids ingestion-based pricing, but publishes no figure, so the quote decides.
Switch from Splunk Enterprise Security if data residency or NIS2 pressure rules out a US-owned cloud service.
Guardsix (formerly Logpoint): complete review · Visit the product page →
Three packages, Essentials, Advanced and Ultimate, climbing from SIEM to deception and AI triage to XDR with an embedded forensics agent. The vendor also sells managed detection separately. Retention beyond the bundled window and some add-ons cost extra, and no price is public.
Switch from Splunk Enterprise Security if you would rather hand part of the alert watching to a vendor.
Rapid7 Incident Command: complete review · Visit the product page →
Sits on the Falcon platform with an index-free design. Data from licensed Falcon modules arrives with no extra ingestion charge, and the SIEM can be bought alone for third-party data. A buyer on another endpoint product loses that advantage and faces a platform commitment.
Switch from Splunk Enterprise Security if CrowdStrike already protects your endpoints and you want its telemetry free of ingest fees.

Behavior analytics sits at the center, with UEBA aimed at insider threat cases. After the LogRhythm merger it sells two lines, New-Scale in the cloud and a self-hosted LogRhythm SIEM. Quote and demo only, so the product to be bought must be settled first.
Switch from Splunk Enterprise Security if insider-threat detection by behavior baselines is the use case, and a self-hosted option matters.
A Google Cloud service for SIEM and SOAR, with detections written in YARA-L, a language that does not carry over to other products. Packages are priced by quote. Rules you wrote in Splunk's search language must be rebuilt rather than moved across.
Switch from Splunk Enterprise Security if you want a cloud service with long hot retention and accept a new rule language.

Sold for on-premises operations on appliances, with licensing by events and flows or by managed virtual servers. Its pages state native Sigma rule import, which helps a team that keeps detections in that format. No price is public and sizing takes planning.
Switch from Splunk Enterprise Security if logs must stay in your own data center and your rules are written in Sigma.
Staying with Splunk Enterprise Security makes sense when you run a staffed SOC that already writes searches and detections in Splunk, and when your data sits in Splunk for other reasons. Risk-based alerting, SOAR and UEBA are integrated, and Premier adds the heavier modules. Rebuilding years of tuned content elsewhere costs months, and a good renewal quote can be cheaper than that work.
Detections written in Splunk's search language need rewriting for the target. Where the old content can be expressed as Sigma, products such as IBM QRadar and Graylog list Sigma import. Start with the ten rules that produced real incidents, not the whole library.
Parallel running lets you compare alert counts on the same week of data. Check the order form for the notice date first, since the general terms renew unless notice is given. For hosted Splunk, content is retrievable for 30 days after the subscription ends, so export early.
No. The pricing page offers a quote button for Enterprise Security, which comes in Essentials and Premier editions on activity, workload or ingest pricing. Expect to supply a data volume to receive a number.
The general terms set automatic renewal for an equal period unless a party gives notice at least 1 day before the term ends, but an order can state otherwise. Read your own order form and calendar the date well ahead.
Yes, for a limited time. The terms say you may retrieve Customer Content from the hosted service during the term, and it stays available for 30 days after termination before deletion. Help with migration may carry a mutually agreed fee.
Yes, with labor attached. Wazuh is free and open source, and Graylog Open is permanently free with a narrower feature set. You run the servers, store the data and tune the rules yourself.
Elastic Security lists per-GB ingest and retention rates, Wazuh Cloud lists monthly plans by agent count, and Graylog lists annual floors. Splunk, Exabeam, Google, IBM, Guardsix and CrowdStrike sell by quote.
Not directly. Splunk searches must be rewritten, and Google's YARA-L is a separate language. Sigma is the shared format, and QRadar and Graylog both say they import it, so convert what you can first.
