# Best SentinelOne Alternatives for Small Business (October 2026) *SentinelOne charges the highest list price we track, sells only through partners and has no recent lab result, so many small offices can do better.* > SentinelOne Singularity Complete includes EDR, ransomware rollback and Linux, but it has the highest published list price we track, sells only through partners, offers no public trial, renews at 120% unless you give notice, and has no independent lab result inside 18 months. This guide names the tracked alternative for each of those reasons. Endpoint Index research (Buyer's guide). Published 2026-10-10, updated 2026-10-10, data as of 2026-10-02. Source: https://endpointindex.com/research/sentinelone-alternatives-small-business/ ## Executive summary **For most small businesses the best SentinelOne alternative is Microsoft Defender for Business: it includes EDR at $36.00 per user per year, against $179.99 per endpoint per year for SentinelOne Singularity Complete, and it has current AV-Test and AV-Comparatives results where SentinelOne has none.** Outside Microsoft 365, ThreatDown Advanced keeps EDR and ransomware rollback in one agent at $79.00 per endpoint per year. If nobody will answer alerts, ThreatDown Elite adds 24/7 managed response. SentinelOne stays the stronger choice for a practice that needs a signed HIPAA BAA alongside EDR, because few vendors offer one. ## What pushes small businesses away from SentinelOne? 1. **Price.** Singularity Complete has the highest published list price of any product we track, and SentinelOne Singularity Control, the entry EDR tier, is $79.99 per endpoint per year. 2. **Partner-only buying, no trial.** SentinelOne shows a list price but sells every licence through partners, and its small-business page offers a demo, not a trial. 3. **The renewal clause.** SentinelOne's master subscription agreement prices a renewal at 120% of the last order unless you give 30 days' written notice or raise a new purchase order. 4. **No recent lab result.** SentinelOne has no AV-Test or AV-Comparatives business result since 2017 and skipped MITRE's 2025 round, so its latest independent result, 72 of 80 substeps on the first run of the 2024 MITRE round, is outside the 18-month window. 5. **No managed response at this tier.** 24/7 managed response is not offered on Complete; SentinelOne offers it only from the higher Commercial tier. ## Which SentinelOne alternative fits your situation? | Your situation | Start with | Why | |---|---|---| | Microsoft 365 business with someone to answer alerts | Microsoft Defender for Business | EDR included, priced per user, current lab results, buy online | | You want EDR and rollback outside Microsoft | ThreatDown Advanced | Both in one agent, plus patch management, sold online | | Nobody will answer alerts | ThreatDown Elite | 24/7 managed response in the list price | | You want recent independent test evidence above all | Sophos Endpoint | Current AV-Test result and MITRE 2025 participation; EDR comes with Sophos EDR | | Your MSP will run it | Huntress Managed EDR | EDR with Huntress's analysts, no Huntress minimum through an MSP | | You need a signed HIPAA BAA with EDR | SentinelOne Singularity Control | Stay with SentinelOne on the cheaper tier rather than leaving | ## How do the cheaper options compare with SentinelOne?

Two gaps run through this group. Microsoft and Sophos carry current lab evidence; ThreatDown and Huntress do not. And rollback, one of SentinelOne's real strengths, is missing from Microsoft and Huntress, so a business leaving SentinelOne for either should test a full restore from backup. ## When does SentinelOne justify its price? SentinelOne Singularity Complete earns its price for a business that needs EDR, ransomware rollback and Linux in one licence, values FedRAMP High authorisation, or must have a HIPAA BAA, which SentinelOne says it may sign. The [Is SentinelOne worth it?](/research/is-sentinelone-worth-it/) analysis and the [SentinelOne pricing guide](/research/sentinelone-pricing/) cover the decision in detail. ## What should you do before your SentinelOne renewal? 1. Find the renewal date and send written notice at least 30 days before it, or the 120% renewal clause applies. 2. List what you use rollback for, and decide how the replacement will recover encrypted files. 3. Check Linux and server coverage: Microsoft needs a separate servers add-on for them. 4. Ask your SentinelOne partner whether a lower tier, such as Singularity Control, meets your needs before you migrate. ## Frequently asked questions ### What is a cheaper alternative to SentinelOne? Microsoft Defender for Business includes EDR at $36.00 per user per year, and ThreatDown Advanced includes EDR and rollback at $79.00 per endpoint per year. Both sell online with no partner quote. ### SentinelOne or Microsoft Defender for Business for a 25-person office? Microsoft Defender for Business for most 25-person Microsoft 365 offices: it costs less, includes EDR and has current lab results. SentinelOne if you need rollback, Linux in the base licence or a HIPAA BAA. The [full comparison](/compare/microsoft-defender-for-business-vs-sentinelone-singularity-complete/) covers the rest. ### Does SentinelOne have a free trial? Not publicly. SentinelOne's small-business page offers a demo; its contract allows an evaluation licence of up to 30 days when SentinelOne grants one. ### Why is SentinelOne not in AV-Test or AV-Comparatives? SentinelOne has not entered either lab's business testing since 2017, and it chose not to take part in MITRE's 2025 evaluation. The [lab results scorecard](/research/endpoint-security-lab-test-results/) shows which vendors are tested where. ## Methodology and caveats Prices, capabilities, contract terms and lab results come from each product's page on Endpoint Index, every value sourced and dated. SentinelOne's renewal clause is quoted from section 11.1 of its master subscription agreement. Partners may quote below SentinelOne's list price; the comparison uses list prices because they are the only public figures. ## Sources 1. SentinelOne.
