Overview
SentinelOne is an endpoint and extended detection-and-response vendor whose Singularity Platform competes directly with CrowdStrike Falcon and Microsoft Defender for Endpoint at the top of the EDR market. Founded in 2013 and headquartered in Mountain View, California, the company went public on the NYSE in 2021 under the ticker S and reported revenue of roughly $821 million for the fiscal year ended January 2025, making it one of the two clear pure-play challengers to CrowdStrike at enterprise scale. Its technical signature is on-agent behavioural AI: the Sentinel agent makes detection and one-click rollback decisions locally rather than depending entirely on cloud lookups, which is the basis of its appeal for low-latency and partially connected environments.
The 2026 platform extends well beyond classic EDR into Singularity XDR, Purple AI for analyst assistance, identity threat detection, and cloud workload and posture protection. SentinelOne is consistently rated among the strongest products in the category for raw detection efficacy and automated response. The buyer decision is less about whether the core EDR is capable — it is — and more about console workflow maturity, the cost of the cloud and identity modules, and how the platform compares operationally to CrowdStrike for a given team's scale and staffing.

Pricing
| Tier | Per endpoint / month | Annual | Included |
|---|---|---|---|
| Singularity Core | $5.83 | ~$69.99/yr | EPP, static and behavioural AI (no EDR) |
| Singularity Control | $6.67 | ~$79.99/yr | Core plus device and firewall control |

| Singularity Commercial | $17.50 | quote | Complete plus identity and added modules |
Pricing verified June 2026 from published reseller list pricing; figures vary by volume and term. Ranger, Vigilance MDR and Singularity Cloud are priced separately and materially increase total contract value. Enterprise pricing requires a quote.
Strengths
- Top-tier detection efficacy, consistently strong in independent MITRE ATT&CK evaluations
- On-agent autonomous response works in low-bandwidth and partially disconnected environments
- Ransomware rollback is a genuine, differentiated recovery capability
- Broad single-platform reach across endpoint, identity, cloud and data
- Frequently undercuts CrowdStrike on negotiated price for comparable scope
Limitations
- Lower tiers (Core and Control) exclude EDR entirely; meaningful protection requires Complete or above, so the headline entry price is misleading
- Console workflow and reporting are widely seen as less polished than CrowdStrike's, with a steeper tuning curve
- Add-on modules (Ranger, Cloud, Identity, Vigilance) stack quickly and can push total cost above the simple per-endpoint figure
- Some teams report more initial false positives requiring policy tuning during onboarding
- Smaller partner and MDR ecosystem than the market leader in some regions
Buyer Considerations
The decisive evaluation question for most buyers is SentinelOne versus CrowdStrike, and the honest answer is that both clear the detection bar; the separation is operational. SentinelOne's on-agent autonomy and rollback suit environments with intermittent connectivity or strict recovery requirements, and its pricing is often more aggressive. CrowdStrike tends to win where console maturity, threat-intelligence depth and a larger services ecosystem dominate the requirement. Scope the quote at the Complete tier or above — Core and Control are not a like-for-like EDR comparison — and price the identity and cloud modules the security team actually intends to use. Run both finalists through a production proof of value on real endpoints; vendor-run bake-offs rarely surface the tuning overhead that defines the day-to-day experience.
User Sentiment
Aggregate sentiment across public review platforms is strongly positive on protection quality. Buyers frequently highlight detection accuracy, the value of automated remediation, and ransomware rollback as standout capabilities, and security teams in disconnected or OT-adjacent environments single out the offline autonomy. The most common reservations concern operational polish rather than efficacy: reviewers describe the management console as powerful but busier and less intuitive than CrowdStrike's, and several note a tuning period to reduce early false positives. Pricing sentiment is generally favourable on the core product but more guarded once add-on modules are included, with buyers cautioning peers to scope the full module set before signing. Support experiences are mixed and correlate with contract tier and whether managed services are purchased. The overall picture is of a top-tier detection platform whose main friction is administrative maturity, not security outcomes.
