Recommended Actions

  1. Obtain and execute Microsoft's Data Processing Addendum (DPA) for Teams — download it directly from https://aka.ms/DPA — and retain a signed copy alongside your TPSP list for QSA review under PCI-DSS 4.0 Requirement 12.8.
  2. Download Microsoft's SOC 2 Type II report and ISO 27001 certificate from the Microsoft Service Trust Portal (https://servicetrust.microsoft.com), which requires a free Microsoft account — these documents confirm the security controls underpinning Teams and satisfy PCI-DSS 12.8.5 TPSP due diligence requirements.
  3. Retrieve Microsoft's current subprocessor list from the Microsoft Privacy portal (https://privacy.microsoft.com) and document which subprocessors have access to data flowing through Teams; retain this with your GDPR and CCPA compliance records.

Frequently asked about Microsoft Teams

Is Microsoft Teams safe to use as a vendor?+
Microsoft Teams 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 Microsoft Teams's full risk profile.
Does Microsoft Teams have SOC 2 certification?+
To verify whether Microsoft Teams 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 Microsoft Teams FedRAMP authorized?+
Based on ThirdProof's investigation, Microsoft Teams holds FedRAMP authorization. Full details including authorization level and scope are available in the ThirdProof investigation report.
Has Microsoft Teams 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 Microsoft Teams. 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 Microsoft Teams on any sanctions lists?+
ThirdProof screens Microsoft Teams against OFAC SDN, consolidated international sanctions lists, and PEP (Politically Exposed Persons) databases. The screening uses entity name verification to reduce false positives from similar names. If Microsoft Teams 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.
How do I assess Microsoft Teams for vendor risk?+
ThirdProof investigates Microsoft Teams autonomously in under 2 minutes using 24 intelligence sources — no questionnaires, no vendor participation required.
