Recommended Actions

  1. Request Zscaler's current SOC 2 Type II report and bridge letter — contact their security team or check https://www.zscaler.com/privacy-compliance/compliance-and-standards where the report may be available under NDA. Verify the audit period covers the last 12 months.
  2. Manually review https://zscaler.com/legal/subprocessors to enumerate all subprocessors; if the page is dynamically rendered, request a static copy from Zscaler's privacy or legal team and document each subprocessor in your vendor risk register.
  3. Request clarification on Zscaler's AI data handling practices — specifically whether customer data is used to train AI models, what retention periods apply to AI-processed data, and whether Copilot can be disabled or data-isolated for your tenant. Ask for this in writing or as an addendum to your DPA.

Is Zscaler safe to use as a vendor?+

Has Zscaler had any data breaches?+
Data breach history is an important signal for any vendor, particularly cloud security platforms like Zscaler 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 Zscaler on any sanctions lists?+
Sanctions screening is standard due diligence for cloud security vendors. ThirdProof screens Zscaler against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Zscaler or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Zscaler for vendor risk?+
Assessing Zscaler as a cloud 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?+

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.

Zscaler 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 Zscaler 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.
