Vendor Privacy Assessment
Evaluate third-party vendor websites for PII exposure before sharing customer data. Part of your GDPR due diligence.
Why Vendor Assessment Matters
"Controllers shall use only processors providing sufficient guarantees to implement appropriate technical and organisational measures in such a manner that processing will meet the requirements of this Regulation."
— GDPR Article 28(1)Under GDPR, you're responsible for ensuring your vendors handle personal data appropriately. If a vendor you share customer data with has poor security practices (like exposing PII on their website), you could be held liable for inadequate due diligence.
Red Flags in Vendor Websites
A vendor's public website can reveal a lot about their internal data handling practices. Here's what piisafe.eu checks:
Exposed Customer Data
Real customer names, emails, or account details visible in HTML source, error messages, or cached pages. Indicates serious security issues.
Financial Data in URLs
Credit card numbers, bank accounts, or payment tokens in URL parameters. Often indexed by search engines.
Test Data in Production
Sample SSNs, dummy credit cards, or "test@example.com" emails visible on live pages. Suggests poor deployment practices.
Debug Information
Stack traces, API responses, or internal system details exposed. Could reveal infrastructure vulnerabilities.
No PII Detected
Clean scan with Grade A. Suggests good data handling practices and awareness of privacy requirements.
Proper Masking
Examples use clearly fake data (John Doe, 555-0100, 4111-****-****). Shows intentional privacy considerations.
Vendor Assessment Checklist
Use this checklist when evaluating a new vendor. piisafe.eu scans help with items 3-5.
Does the vendor have ISO 27001, SOC 2, or equivalent certifications?
Is there a GDPR-compliant DPA covering data handling, sub-processors, and breach notification?
Scan the vendor's public website for exposed PII. Grade A indicates good practices; Grade D-F is a red flag.
Scan vendor documentation and help pages for exposed examples using real PII patterns.
Check case studies and testimonials for unmasked customer data that could indicate careless handling.
Where is customer data stored? EU residency requirements may apply under GDPR Article 44.
Has the vendor had any public data breaches? Check haveibeenpwned.com and news archives.
How to Conduct a Vendor Scan
- Identify Key Pages: Start with the vendor's main website, documentation, and customer portal login page.
- Run piisafe.eu Scan: Enter the vendor's URL. Use the GDPR preset for EU vendors or PCI-DSS for payment processors.
- Review Findings: Any Grade below B warrants further investigation. High-severity findings (SSN, credit cards) are immediate red flags.
- Document Results: Export the scan report and include it in your vendor assessment file. This demonstrates due diligence.
- Follow Up: If issues are found, ask the vendor to address them before signing contracts or sharing data.
