Recommended Actions

  1. Conduct manual sanctions screening: Cross-reference Zscaler, Inc. and its known subsidiaries against the OFAC SDN list (home.treasury.gov/policy-issues/financial-sanctions/sdn-list), the EU consolidated sanctions list (eeas.europa.eu/topics/sanctions), and the UN consolidated list. Document results and retain for your TPSP file.
  2. Obtain and review the vendor's current SOC 2 Type II report: Contact Zscaler's security team directly or check trust.zscaler.com — many enterprise vendors publish reports under an NDA request. Confirm the audit period covers the last 12 months and that the scope includes systems relevant to your deployment.
  3. Verify PCI-DSS compliance status: Request Zscaler's current Attestation of Compliance (AOC) or confirmation of their PCI-DSS certification scope from their compliance team. This is required under PCI-DSS 4.0 Requirement 12.8.4 to confirm the vendor undergoes annual PCI assessments.

Frequently asked about Zscaler

Is Zscaler safe to use as a vendor?+
Zscaler can be evaluated for vendor safety by checking sanctions databases (OFAC, EU, UN), verifying business registration through legal entity registries like GLEIF, scanning for adverse media coverage including data breaches and regulatory actions, and assessing domain security and cyber risk posture. ThirdProof automates this entire investigation across 24 intelligence sources and produces a deterministic risk tier (1-5 scale) with a confidence score. Run a free investigation to see Zscaler's full risk profile.
Does Zscaler have SOC 2 certification?+
To verify whether Zscaler holds SOC 2 certification, ThirdProof scans the vendor's trust page and security documentation for certification claims, then cross-references those claims against independent registries where available (such as the FedRAMP Marketplace for FedRAMP authorization). Certifications are classified as independently verified, vendor attested, or not found in evidence — ensuring you know the verification level of each claim.
Is Zscaler FedRAMP authorized?+
Based on ThirdProof's investigation, Zscaler holds FedRAMP authorization. Full details including authorization level and scope are available in the ThirdProof investigation report.
Has Zscaler had any data breaches?+
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 involving Zscaler. Each finding is linked to its original source with severity classification. The investigation also checks SEC EDGAR for enforcement-related filings and FDIC records for financial institution failures, providing a comprehensive public record review.
Is Zscaler on any sanctions lists?+
ThirdProof screens Zscaler against OFAC SDN, consolidated international sanctions lists, and PEP (Politically Exposed Persons) databases.

If Zscaler or any associated officers appear on a sanctions list, this triggers an automatic escalation to the highest risk tier. No sanctions match is confirmed through a clean screening report in the investigation output.
