TL;DR
Webflow handles infrastructure security well for marketing sites. Enable reCAPTCHA on forms, be cautious with third-party embed codes, and don't store sensitive data in Webflow's CMS. For applications requiring user authentication or sensitive data handling, use dedicated backend services alongside Webflow.

Data Handling

- Set up form notification emails securely
Important: Webflow form submissions are visible to anyone with Editor access to your project. Don't collect data that shouldn't be seen by your team.
Third-Party Integrations
Many Webflow sites use custom code and integrations:
Custom Code Risks
- Review any JavaScript you embed
- Only use trusted third-party scripts

Memberstack, Outseta, etc.
- Third-party membership tools add complexity
- Review their security practices
- Understand where user data is stored
- Configure their security settings properly
CMS Security
Webflow's CMS is for content, not sensitive data:

When Webflow Isn't Enough
Consider additional tools when you need:
- User authentication: Use Memberstack, Outseta, or a backend
- Sensitive data storage: Use a proper database
- Payment processing: Use Stripe directly with proper backend
- Complex forms: Use dedicated form services
