Executive Summary Preview

Microsoft 365 is a globally deployed enterprise productivity and collaboration platform operated by Microsoft Corporation, assessed here at a medium data access level. The rule engine has assigned this vendor a Tier 2 (High Risk) rating, driven primarily by recent adverse media coverage of ransomware and phishing-based attacks targeting the platform — a predictable but material risk profile for any service with over 400 million users.

Recommended Actions

  1. Obtain Microsoft's current SOC 2 Type II report and bridge letter: visit the [Microsoft Service Trust Portal](https://servicetrust.microsoft.com) (login required with a Microsoft 365 organizational account), navigate to 'Audit Reports', and download the most recent SOC 2 Type II report. Confirm the audit period end date is within the last 12 months. File this with the present ThirdProof report as combined CC9.2 evidence.
  2. Clarify AI/Copilot data training commitments in writing: contact your Microsoft account team or review the Microsoft Products and Services Data Protection Addendum (DPA) to confirm whether Microsoft 365 Copilot features train on your organization's customer or employee data, and whether opt-out is available. Request a written confirmation and attach it to this assessment.
  3. Implement phishing-resistant MFA and disable legacy authentication: in your Microsoft 365 admin center, enable Conditional Access policies requiring FIDO2 or certificate-based MFA for all users, and block legacy authentication protocols (Basic Auth, SMTP AUTH where unused). This directly mitigates the OAuth and phishing breach vectors identified in rf-1. Target completion: within 30 days.

Has Microsoft 365 had any data breaches?+
Data breach history is an important signal for any vendor, particularly productivity platforms like Microsoft 365 that handle organizational documents and communications. 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 Microsoft 365 on any sanctions lists?+
Sanctions screening is standard due diligence for productivity vendors. ThirdProof screens Microsoft 365 against OFAC SDN, consolidated international sanctions lists, and PEP databases. The screening uses entity name verification to reduce false positives. If Microsoft 365 or any associated officers appear on a sanctions list, this triggers automatic escalation to the highest risk tier.
How do I assess Microsoft 365 for vendor risk?+
Assessing Microsoft 365 as a productivity vendor involves verifying SOC 2 Type II and FedRAMP 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.

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.
