How secure is Webflow?
Get instant answers about your app's security.
Short Answer
Webflow's platform layer has no known systemic vulnerabilities, but Webflow apps regularly ship with misconfigurations that leave user data exposed. Platform security ≠ app security.
Detailed Answer
What Webflow gives you out of the box
Webflow combines visual design with CMS capabilities. Understanding security implications of CMS settings and custom code helps protect your site.
What Webflow leaves to you
VAS scans your Webflow site for security headers, exposed data, and custom code vulnerabilities.
The security gaps that actually appear in Webflow apps
- **Custom Code XSS** — Pasted JavaScript embeds can introduce XSS vulnerabilities.
2. **CMS Content Visibility** — CMS data may be exposed in page source if visibility not configured.
3. **Third-Party Script Risks** — Embedded scripts have full page access.
Platform security is strong where Webflow controls the stack. The gaps above all sit in the application layer — where Webflow's guarantees end and yours begin.
Verdict
Webflow can be run securely. Treat "is Webflow secure" as a deployment-time question, not a platform question: run a security scan, verify database access controls are configured, and close the specific gaps above. Platforms with better defaults (e.g. enforced database access controls) would reduce the work — but none of them make scanning unnecessary.

Expert Perspectives
“There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.”
“It's not really coding - I just see stuff, say stuff, run stuff, and copy paste stuff, and it mostly works.”

Is Webflow secure enough for production?
Yes — once verified. The platform layer handles infrastructure reliably; the application layer (access controls, secrets, auth) is where production readiness is won or lost. Verification is a scan + manual review of database access controls, not a vibe check.
What percentage of Webflow apps have security issues before review?
Based on the breaches we track and community reporting, the majority of Webflow apps deployed without a pre-launch scan have at least one critical or high-severity finding. The #1 recurring finding is "Custom Code XSS". This is not unique to Webflow — it's the base rate for AI-assisted development — but it means the default state of a shipped Webflow app is "unverified."
Does Webflow itself have security certifications (SOC 2, ISO 27001)?
Platform certifications from Webflow apply to the Webflow infrastructure — not to your app built with Webflow. Even if Webflow is SOC 2-compliant, your app can still leak data through misconfigured database access controls, exposed secrets, or missing access checks. Compliance for your app is a separate effort; the platform's certifications are necessary but never sufficient.
