Executive Summary

AI-generated analysis for Zendesk

Zendesk (zendesk.com) is a well-established SaaS customer support platform serving 200,000+ companies worldwide, assessed here at Tier 3 (Moderate Risk) with a 93% confidence score, reflecting a strong compliance posture offset by a recurring pattern of security incidents and an unresolved concern regarding AI training data transparency. Zendesk presents several meaningful positive signals that compliance teams should document:

Key Findings

  • FedRAMP LI-SaaS authorization is independently verified via the FedRAMP Marketplace (authorized June 2022), providing strong assurance for government-adjacent deployments.
  • SOC 2 Type II compliance is claimed on Zendesk's trust page (https://zendesk.com/trust-center) and should be requested directly from the vendor.
  • ISO 27001:2022, ISO 27017:2015, ISO 27018:2019, ISO 27701:2019, CSA STAR AI Levels 1 & 2, PCI DSS, HIPAA, and Cyber Essentials Plus are all claimed on the vendor's trust page.
  • The domain carries a 20-year registration history, clean Malware detection service status, zero malware blacklist listings, and a 0% IP abuse confidence score.
  • Zendesk's published AI policy states zero data retention for third-party LLM processing and references NIST AI RMF as a governance framework.
  • The HTTP security posture received a grade of B (70/100) from independent scanning, indicating a generally well-configured environment. Areas

Area Requiring Attention

requiring attention include a documented pattern of security incidents: a 2023 employee phishing attack that led to a breach, a subsequent potential data breach, and a more recent (April 2026) incident in which support tickets were stolen from the Zendesk platform, resulting in a downstream data breach at a customer (Hims & Hers). Additionally, an October 2025 Krebs on Security report highlighted an email-bombing vulnerability related to lax authentication in Zendesk. The vendor's AI training data commitment is described as unclear in the policy text despite adjacent language suggesting customer data is not used for LLM training — this ambiguity warrants direct clarification. Thirteen open ports were detected on Zendesk's infrastructure, which sits at the upper end of typical SaaS exposure. Subprocessor data could not be automatically parsed from the vendor's published page, requiring manual review. The TLS certificate for zendesk.com expires in approximately 56 days and should be monitored for timely renewal. On balance, Zendesk is a mature, heavily certified platform with a credible compliance program, but the recurring security incident history — particularly the platform-level support ticket breach in 2026 — elevates risk for buyers processing sensitive customer data. A conditional approval is warranted, subject to obtaining current audit reports and direct confirmation of AI data handling commitments.

Independence Statement

All evidence in this report was independently sourced from external data providers, public registries, and open-source intelligence without vendor participation or notification.

Steps to address findings for Zendesk

  1. 1

    Request Zendesk's current SOC 2 Type II report and a bridge letter confirming audit coverage through the present date — contact Zendesk's security team via https://zendesk.com/trust-center or submit a request through your account manager. Confirm the audit period post-dates the January 2023 phishing incident remediation.

  2. 2

    Request a post-incident security advisory from Zendesk addressing the April 2026 support ticket exfiltration incident (reported by BleepingComputer). Ask specifically: what access control failures were exploited, what remediation steps were taken, and whether your tenant's data was potentially in scope.

  3. 3

    Manually review Zendesk's subprocessor list at https://trust.zendesk.com/subprocessors and identify all third parties with access to your customer support data. Retain a dated export in your vendor risk register and confirm each subprocessor is covered under Zendesk's DPA.

  4. 4

    Obtain written clarification from Zendesk's security or legal team confirming whether customer data is used for AI model training under your contracted product tier. Reference the AI data use policy at https://support.zendesk.com/hc/en-us/articles/5729714731290-Zendesk-AI-Data-Use-Information and ask for DPA-level contractual confirmation of any no-training commitments.

  5. 5

    Download Zendesk's ISO 27001:2022 certificate directly from their trust page (https://zendesk.com/trust-center) and record the certificate number, issuing body, and expiry date in your vendor risk register. This provides vendor-attested documentation even without independent registry verification.

  6. 6

    Set a calendar reminder to re-verify the zendesk.com TLS certificate expiry (currently May 31, 2026) within 30 days. If still unrenewal after 45 days, escalate to your Zendesk contact. This is a low-effort check that prevents unexpected disruption.

  7. 7

    Review Zendesk's DPA and BAA (if applicable to your use case) to confirm contractual coverage for the high-data-access classification assigned in this assessment. Zendesk's DPA should be available at https://zendesk.com/trust-center.

Data Coverage Notes

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

  • Certificate Transparency log data (Certificate Transparency service) was unavailable during this assessment; certificate issuer information was obtained via direct TLS handshake only, and subdomain enumeration through CT logs was not possible.
  • Open Threat Exchange (OTX) pulse data was unavailable during this assessment and could not be used to supplement domain threat intelligence.
  • External cyber risk scoring was not available for this assessment; infrastructure and reputation findings rely on directly queried sources.
  • Subprocessor data could not be automatically extracted from trust.zendesk.com due to page rendering or structural limitations; the subprocessor list requires manual review.
  • ISO 27001 certification status could not be independently verified through the IAF CertSearch registry during this assessment; the certification is claimed on the vendor's trust page but is classified as vendor-attested only.
  • HITRUST certification status could not be verified through the HITRUST directory during this assessment; no evidence of HITRUST certification was found.
  • The web archive history source indicates a first-indexed date of November 2024, which reflects indexing of the specific URL pattern queried rather than the actual establishment date of zendesk.com, which WHOIS confirms was registered in 2005. This is a data artifact and does not reflect a new or unestablished domain.
  • SOC 2 reports are confidential documents with no public registry; Zendesk's SOC 2 Type II status is vendor-attested via trust page and cannot be independently verified without requesting the report directly from the vendor.

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.
