Is it safe to store sensitive data on Webflow's CMS?

TL;DR
  • Webflow CMS is only suitable for public-facing content, lacking encryption, access control, and compliance for sensitive data.
  • Use secure external services and API integrations for storing and displaying confidential information safely.

Webflow’s CMS is not designed for storing sensitive or confidential data such as personal identifiers, medical records, or payment information.

1. CMS Is Meant for Public Content

  • Webflow CMS data is publicly accessible to anyone with the correct URL or API access, unless controlled through page-level permissions.
  • It should only be used to store non-sensitive, public-facing content, such as blog posts, product descriptions, event details, etc.

2. No Encryption or Access Control for CMS Items

  • Webflow does not offer encryption at rest for individual CMS items or fields.
  • There’s no built-in user-based access control at the CMS item level (e.g., roles or field-level permissions).

3. Not Compliant for Sensitive Use Cases

  • Webflow is not HIPAA, GDPR (in full scope), or PCI-DSS compliant if used for storing regulated sensitive data.
  • Data stored in the CMS may be cached or replicated across CDN servers, making data residency and control more difficult.

4. Alternatives for Sensitive Data Handling

  • Use external, secure services that specialize in handling sensitive data (e.g., Firebase, Supabase, Airtable with proper privacy controls).
  • Display the necessary info on Webflow using API integration or custom embeds, keeping the data secure and off CDN/public CMS records.

Summary

Do not store sensitive data in Webflow's CMS. It lacks the necessary security, access control, and compliance features. Use external services for any confidential or private information.
