Review and harden your vendor agreements and data processing agreements

2-4 hr, more with many vendors Impact: medium Effort: medium ✓ Manual completion

Reviewing and hardening your vendor agreements and data processing agreements ensures every third-party service with access to your data or systems has a real contractual obligation to handle that access responsibly, not just an informal assumption of good practice.

Your legal and security exposure extends to every vendor with meaningful access, a data processing agreement is what actually holds them accountable, not just trust.

How to do it

  1. 1
    List every vendor with meaningful data or system access
    Hosting, email services, analytics, payment processors, any third party with real access.
  2. 2
    Confirm a data processing agreement exists for each
    Where relevant, particularly for GDPR compliance if you handle EU user data.
  3. 3
    Review terms for genuine adequacy
    Confirm the agreement actually covers real security and data handling obligations, not just boilerplate language.
  4. 4
    Address any gaps found
    Request a proper agreement from vendors that lack one, or reconsider the relationship if they will not provide adequate terms.
