Executive Summary

AI-generated analysis for SentinelOne

SentinelOne (sentinelone.com) is a publicly traded cybersecurity vendor offering endpoint detection and response (EDR) and broader security platform services, legally registered as SENTINELONE, INC.

Area Requiring Attention

in Delaware with an active LEI. The vendor presents a largely clean technical security posture — no malicious domain flags across 94 security engines, a strong SSL/TLS grade of A+, clean IP reputation, and no active threat intelligence signals — but carries a Tier 3 (Moderate Risk) rating primarily driven by unverified compliance certifications and a below-average HTTP security header configuration. Historical media coverage references ransomware in the context of SentinelOne's own research and product marketing, not as indicators of a breach or enforcement action. For a retail organization evaluating this vendor as a third-party service provider under PCI-DSS 4.0, independent confirmation of the claimed PCI-DSS and SOC 2 Type II certifications is the critical outstanding action before onboarding.

Independence Statement

All evidence presented in this report was independently sourced from external data providers without vendor participation, notification, or input.

Steps to address findings for SentinelOne

  1. 1

    PRIORITY 1 — Request PCI-DSS Attestation of Compliance (AOC) within 30 days: Contact SentinelOne's security team via trust.sentinelone.com or security@sentinelone.com and request their current PCI-DSS AOC or ROC. This is a mandatory QSA requirement under PCI-DSS 4.0 Requirement 12.8.4 for TPSPs that could impact cardholder data security. Retain the document with your TPSP register.

  2. 2

    PRIORITY 2 — Obtain SOC 2 Type II report within 30 days: Request SentinelOne's most recent SOC 2 Type II audit report. Many enterprise vendors share this under a mutual NDA — ask their sales or security team, or check trust.sentinelone.com for a downloadable version. Confirm the audit period covers the last 12 months.

  3. 3

    PRIORITY 3 — Verify FedRAMP authorization status independently within 30 days: Navigate to marketplace.fedramp.gov and search for 'SentinelOne' to independently confirm the FedRAMP High claim listed on their trust page. Document the result (confirmed, in-process, or not found) in your TPSP due diligence file.

  4. 4

    PRIORITY 4 — Conduct manual sanctions screening within 14 days: Because automated sanctions screening was unavailable during this assessment, manually verify SentinelOne, Inc. against OFAC's SDN list (sanctionssearch.ofac.treas.gov), the EU Consolidated Sanctions List, and the UN Sanctions List before proceeding with onboarding.

  5. 5

    PRIORITY 5 — Review subprocessor list manually within 45 days: Visit trust.sentinelone.com/subprocessors directly and document all listed subprocessors. Cross-reference against your organization's approved third-country data transfer list for GDPR compliance. Confirm a Data Processing Agreement (DPA) is in place with SentinelOne covering EU consumer data.

  6. 6

    PRIORITY 6 — Establish a shared responsibility matrix for PCI controls within 60 days: Under PCI-DSS 4.0 Requirement 12.8.5, document which PCI controls SentinelOne manages versus your organization. Request SentinelOne's shared responsibility matrix or customer responsibility guide from their enterprise support team.

  7. 7

    PRIORITY 7 — Follow up on HTTP security header remediation within 60 days: Raise the HTTP security scanner D grade with SentinelOne's security team and request a written response or remediation timeline. Re-test at observatory.mozilla.org after remediation is claimed.

Data Coverage Notes

Some data sources may have had limited availability during this assessment. This does not reflect negatively on the vendor.

  • Sanctions and watchlist screening data was unavailable during this assessment. Manual sanctions screening against OFAC, EU, and UN lists is recommended as a compensating control before vendor onboarding.
  • Certificate Transparency log data could not be retrieved during this assessment, limiting visibility into SentinelOne's full subdomain footprint and certificate issuance history.
  • Web archive history data was unavailable, though the domain's 18-year registration age and high web popularity rankings provide sufficient alternative evidence of domain establishment.
  • The subprocessor page at trust.sentinelone.com/subprocessors was located but no structured subprocessor entries could be extracted due to a non-standard page format. A manual review of this page is recommended to identify data sub-processors relevant to GDPR Article 28 and PCI-DSS shared responsibility.
  • External cyber risk scoring was not available from all sources during this assessment, which may limit the completeness of the infrastructure risk picture.
  • FedRAMP Marketplace registry confirmation for SentinelOne's claimed FedRAMP High authorization was not returned during this assessment and should be independently verified at marketplace.fedramp.gov.

The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending SentinelOne a single email or waiting for a vendor response.
Is SentinelOne safe to use as a vendor?+
SentinelOne is a endpoint security vendor that handles organizational data. Safety depends on their current security posture, certification status, and how they handle your specific data. ThirdProof automates this evaluation across 27 intelligence sources — sanctions databases (OFAC, EU, UN), business registration verification, adverse media scanning, and cyber risk assessment — producing a deterministic risk tier with confidence score plus an auto-filled security questionnaire. Run a free investigation to see SentinelOne's full risk profile.
Does SentinelOne have SOC 2 certification?+
Yes — SentinelOne holds SOC 2 + 6 other certs. Rated Moderate Risk — security header gaps found. See all 3 findings →
Has SentinelOne had any data breaches?+
Data breach history is an important signal for any vendor, particularly endpoint security platforms like SentinelOne that handle organizational data. ThirdProof's adverse media analysis searches multiple news APIs and public records for data breaches, security incidents, lawsuits, regulatory enforcement actions, and financial distress signals. Each finding is linked to its original source with severity classification.
Is SentinelOne on any sanctions lists?+
Sanctions screening is standard due diligence for endpoint security vendors. ThirdProof screens SentinelOne against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If SentinelOne or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess SentinelOne for vendor risk?+
Assessing SentinelOne as a endpoint security vendor involves verifying SOC 2 Type II and applicable industry standards compliance, reviewing their subprocessor chain, and checking sanctions exposure. ThirdProof automates this across 27 intelligence sources in an average of 7 minutes — no questionnaires or vendor participation required. Your first 5 investigations are free.
How long does a ThirdProof assessment take?+
A ThirdProof assessment completes in an average of 7 minutes. 27 intelligence sources are queried in parallel — sanctions databases, business registries, threat intelligence feeds, certificate transparency logs, and more. The result is a deterministic risk tier with confidence score and audit-ready PDF report.
Is ThirdProof free?+
ThirdProof offers 5 free vendor assessments with no credit card required. Each assessment includes the full report — risk tier, confidence score, individual findings, executive summary, and PDF export. Paid plans start at $399/month for teams that need ongoing vendor monitoring.
Can I use a ThirdProof report as SOC 2 audit evidence?+
Yes. ThirdProof reports are designed to satisfy SOC 2 CC9.2 (vendor risk management) requirements. Each report includes SHA-256 integrity verification, methodology disclosure, source attribution for every finding, and AI content labeling. Auditors can independently verify the report's authenticity and trace each finding to its original source.
How is ThirdProof different from a security questionnaire?+
Security questionnaires require vendor participation, take weeks, and produce self-reported answers. ThirdProof queries 27 independent intelligence sources — no vendor involvement needed. Risk tiers are assigned by a deterministic rules engine (not AI opinion), and every finding links to its original source. You get an audit-ready report in an average of 7 minutes instead of waiting weeks for a questionnaire response.

SentinelOne is in your vendor stack. Can you prove you assessed them?

SOC 2 CC9.2, HIPAA, PCI-DSS, and CMMC all require documented vendor due diligence — not just knowing the answer, but having audit-ready evidence you verified it. Most compliance teams can't produce that documentation on demand.

ThirdProof investigates SentinelOne across 27 intelligence sources in an average of 7 minutes — sanctions screening, cyber posture, SOC 2 verification, FedRAMP status, and more. Every investigation produces two deliverables: an audit-ready risk report and an auto-filled security questionnaire your prospects and auditors expect to see.
