0–100, higher is better. How it is calculated

Webflow is a leading technology company specializing in no-code website building and hosting solutions. Founded in 2013 and headquartered in San Francisco, Webflow offers a comprehensive platform that enables marketers, designers, developers, and agencies to design, build, and launch responsive websites without writing code. The platform integrates a flexible CMS, hosting services, SEO tools, and AI-powered optimization features, positioning Webflow as a strong player in the website builder market. The company maintains a professional and consistent brand presence with extensive customer testimonials and social media engagement. Technically, Webflow leverages modern web technologies including JavaScript, GSAP for animations, and integrates third-party services like Intellimize for analytics and Transcend for consent management. Hosting is inferred to be on AWS infrastructure, supported by robust DNS configurations. The website demonstrates excellent performance, mobile optimization, and good accessibility standards, reflecting a mature and well-maintained digital infrastructure. From a security perspective, Webflow enforces HTTPS with strong domain registration protections and employs consent management tools to comply with privacy regulations such as GDPR. While explicit security headers are not fully confirmed in the HTML, the overall posture is strong with no exposed sensitive data or vulnerabilities detected. The absence of a public security.txt or incident response contacts suggests room for improvement in transparency and vulnerability disclosure. Overall, Webflow presents a low-risk profile with high business credibility, strong technical implementation, and good privacy compliance. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, enhancing security header implementation, and providing clearer incident response channels to further strengthen trust and security posture.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • DNS health: did not complete in this scan.
  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Webflow operates as a SaaS provider in the technology sector, targeting a broad audience including marketers, designers, developers, and agencies. Its competitive advantage lies in its no-code visual builder combined with powerful CMS and hosting capabilities, enabling rapid website deployment without traditional coding. Revenue streams likely include subscription plans, enterprise solutions, and partner programs. The company demonstrates growth through new features like AI integration and Webflow Cloud. Partnerships with analytics and consent management providers enhance its ecosystem. The company maintains a strong market position with a large user base and extensive educational resources such as Webflow University.

Security posture

Webflow exhibits a mature security posture with enforced HTTPS, domain registration protections, and consent management aligned with GDPR. No critical vulnerabilities or exposed sensitive data were found in the website content. However, the lack of a published security.txt and incident response contacts limits transparency. Security headers are partially confirmed but could be improved. The use of reputable third-party services and a dedicated security page indicates a proactive approach to security. Overall, Webflow is well-prepared for common threats but should enhance disclosure and incident response readiness.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file to provide clear vulnerability disclosure and contact information.
  3. Implement and explicitly confirm security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide public incident response contact channels (e.g., security@ or abuse@ emails) to improve transparency and trust.
  5. Regularly audit and monitor third-party scripts and integrations for potential vulnerabilities.

Technical notes

Notes

It integrates third-party analytics and consent management tools, indicating a sophisticated approach to user experience and privacy compliance. Hosting is likely on AWS infrastructure, supported by multiple AWS DNS nameservers. The site demonstrates fast performance, excellent mobile responsiveness, and good SEO optimization with proper meta tags and structured data. Accessibility features are present but could be further enhanced. The technical stack is modern and well-maintained, supporting scalability and reliability.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
