Why Businesses Must Monitor Vendor Compliance Under the General Data Protection Regulation (GDPR)
When Your Partner’s Violation Becomes Your Problem
In today’s global economy, it’s standard practice for companies to rely on third-party vendors—cloud service providers, email marketing tools, payment processors, and more. While outsourcing can boost efficiency, it also introduces significant data privacy risks.
Under the General Data Protection Regulation (GDPR)—Europe’s data protection law—businesses are fully accountable for the actions of their vendors when it comes to handling personal data. If your vendor misuses or exposes personal data, your company could be held legally responsible.
The GDPR : Your Responsibilities Don’t End with Outsourcing
The General Data Protection Regulation (GDPR) (Regulation (E.U.) 2016/679) sets strict requirements for businesses that control or process the personal data of individuals in the European Union. If your company operates in or serves customers in the E.U., the GDPR applies—even if your business is based outside of Europe.
Read the official regulation here:
🔗 European Commission – GDPR Text
Under the GDPR, your business is considered a:
- Controller – if you determine why and how personal data is processed.
- Processor – if you process data on behalf of another company (e.g., as a vendor).
If you’re a controller using third-party vendors (processors), you are responsible for ensuring they are GDPR-compliant. Article 28 of the GDPR outlines mandatory due diligence and contractual obligations between controllers and processors.
Why Third-Party Vendors Are a Legal and Financial Risk
Even if you’ve invested in your own data protection programs, a single weak vendor could undermine your entire compliance strategy.
Real Business Risks from Vendor Non-Compliance:
- Regulatory Fines: Up to €20 million or 4% of annual global turnover, whichever is higher
- Loss of Customer Trust: Data leaks caused by third parties erode public confidence in your brand
- Contractual Liability: Vendors may not bear the full legal responsibility—you do
- Data Breaches: Insecure vendors increase your risk of breach notification obligations under Articles 33 and 34 of the GDPR
Example: In 2020, the British Airways data breach (which resulted in a €20M GDPR fine) was traced back to vulnerabilities in third-party code.
What the GDPR Requires You to Do
The GDPR clearly outlines that due diligence is not optional. Businesses must proactively verify that vendors handling E.U. personal data meet security and compliance requirements.
Article 28 Requirements for Businesses Using Vendors:
- Conduct Vendor Due Diligence
Review the vendor’s technical and organizational security measures before engagement. - Sign a Data Processing Agreement (DPA)
The GDPR-compliant contracts must define the scope, purpose, and security requirements for data handling. - Monitor & Audit Vendor Performance
The relationship doesn’t stop with a signed DPA. Controllers must regularly review vendor compliance. - Minimize Data Sharing
Only share data necessary for the vendor’s function, aligned with the data minimization principle. - Ensure International Data Transfer Compliance
If vendors are based outside the E.U., ensure legal safeguards (e.g., Standard Contractual Clauses).
