Executive Summary

AI-generated analysis for Zendesk

Zendesk is a widely-recognized SaaS customer service platform with an established 20-year domain history, clean real-time threat intelligence across 94 security engines, and a published trust page citing an extensive compliance portfolio.

Area Requiring Attention

The rule engine has assigned a Tier 3 (Moderate Risk) rating, driven primarily by aging historical security incidents, an inability to independently verify any of the 11 claimed certifications through public registries, the absence of a publicly accessible subprocessor list, and a moderate infrastructure footprint. No current adverse media, sanctions concerns, malware flags, or active enforcement actions were identified in this assessment. For retail and e-commerce buyers, Zendesk's vendor-attested PCI-DSS and GDPR/CCPA claims are particularly relevant given cardholder data proximity and consumer privacy obligations — but these claims require confirmation through direct document requests before full reliance. A conditional engagement posture is warranted until certification documentation and supply chain transparency can be confirmed.

Independence Statement

All evidence in this report was independently sourced from external data providers and public registries without vendor participation or input.

Steps to address findings for Zendesk

  1. 1

    Obtain Zendesk's PCI-DSS Attestation of Compliance (AOC) and a completed Responsibility Matrix documenting which PCI-DSS 4.0 controls Zendesk manages versus your organization — contact their enterprise security team via https://zendesk.com/security and request this within 30 days. This is required to satisfy PCI-DSS 12.8.5.

  2. 2

    Request Zendesk's most recent SOC 2 Type II audit report — ask their security team directly, or check their trust page at https://zendesk.com/security where many vendors provide NDA-gated access. Confirm the audit period covers the last 12 months and review the report for any exceptions relevant to cardholder or consumer data handling.

  3. 3

    Obtain Zendesk's signed Data Processing Agreement (DPA) and subprocessor list before processing any EU or California consumer data. Request these through https://zendesk.com/privacy or your account representative, and confirm the DPA includes GDPR Article 28 sub-processor provisions and CCPA service provider language prohibiting data selling.

  4. 4

    Perform manual sanctions screening of Zendesk against OFAC, EU, and UN consolidated lists to compensate for the unavailable automated screening in this assessment — use the OFAC SDN search tool at https://sanctionssearch.ofac.treas.gov/ and document the results.

  5. 5

    Request post-incident remediation documentation for the January 2023 phishing and data breach events, specifically confirming whether any cardholder data or retail consumer PII was affected and what controls were implemented afterward. Ask your Zendesk account representative or their security team via https://zendesk.com/security.

  6. 6

    Attempt to independently verify Zendesk's claimed FedRAMP LI-SaaS authorization by searching the FedRAMP Marketplace at https://marketplace.fedramp.gov — if found, note the authorization status and package details for your TPSP file. If not found, escalate this discrepancy with Zendesk's security team for clarification.

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 was unavailable during this assessment. Manual verification of Zendesk against OFAC, EU, and UN sanctions lists is recommended before finalizing vendor onboarding.
  • SSL/TLS deep configuration analysis returned a pending scan status with no cached results available; a full cipher suite and protocol assessment for zendesk.com could not be completed at this time.
  • Certificate transparency log data was unavailable, limiting the ability to enumerate subdomains and identify potentially sensitive or misconfigured certificate issuances.
  • Web archive history data was unavailable, though the domain's 20-year registration age (confirmed via WHOIS) provides sufficient domain establishment assurance independently.
  • Open threat exchange reputation data was unavailable; this supplementary threat intelligence source could not contribute to the domain reputation assessment.
  • External cyber risk scoring was not available for this assessment, which may limit quantitative benchmarking against industry peers.
  • FedRAMP LI-SaaS authorization is claimed on Zendesk's trust page, but the FedRAMP public Marketplace registry returned no confirming match — this authorization could not be independently verified.

Can I get an auto-filled security questionnaire for Zendesk?+
Yes. Every ThirdProof investigation of Zendesk produces two deliverables: an audit-ready risk report and a 133-question security questionnaire pre-filled with evidence from 27 independent sources. The questionnaire is mapped to SIG, SOC 2, HIPAA, PCI DSS and 9 other frameworks — answered without sending Zendesk a single email or waiting for a vendor response.
Is Zendesk safe to use as a vendor?+
Zendesk is a customer support vendor that handles customer PII and support records. 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 Zendesk's full risk profile.
Does Zendesk have SOC 2 certification?+
Yes — Zendesk holds SOC 2 + 8 other certs. Rated Moderate Risk — breach history in media. See all 7 findings →
Has Zendesk had any data breaches?+
Data breach history is an important signal for any vendor, particularly customer support platforms like Zendesk that handle customer PII and support records. 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 Zendesk on any sanctions lists?+
Sanctions screening is standard due diligence for customer support vendors. ThirdProof screens Zendesk against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Zendesk or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Zendesk for vendor risk?+
Assessing Zendesk as a customer support 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.

Zendesk 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 Zendesk 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.
