Recommended Actions

  1. Request Square's current ISO 27001 certificate and independently verify it: obtain the certificate number, issuing body, scope, and expiry date, then cross-check at https://www.iafcertsearch.org. Flag any certificate expiring within 90 days.
  2. Request Square Payroll's most recent SOC 2 Type II report and bridge letter — contact your account team or Square's security team directly, as many enterprise vendors provide these under NDA. Review the report's scope to confirm it covers the payroll product specifically.
  3. Manually review the subprocessor disclosure page at https://squareup.com/legal/data-processing, document all listed subprocessors, and cross-reference against your organization's data transfer and approved vendor policies.

Does Square have SOC 2 certification?+
No SOC 2 found. Square rated Moderate Risk — subprocessor list unavailable. See all 3 findings →
Has Square had any data breaches?+
Data breach history is an important signal for any vendor, particularly payments platforms like Square that handle payment card and transaction 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 Square on any sanctions lists?+
Sanctions screening is particularly critical for payments vendors. ThirdProof screens Square against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Square or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Square for vendor risk?+
Assessing Square as a payments vendor involves verifying PCI-DSS and SOC 2 Type II 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.

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.

Every investigation produces two deliverables: an audit-ready risk report and an auto-filled security questionnaire your prospects and auditors expect to see.
