Webflow is a leading SaaS technology company specializing in no-code website building, CMS, hosting, and optimization solutions. Founded in 2013 and headquartered in San Francisco, Webflow serves a broad audience including web designers, developers, agencies, enterprises, freelancers, and startups. The platform enables users to design, build, and launch custom responsive websites visually without writing code, positioning itself strongly in the no-code market segment with enterprise-grade offerings and extensive integrations. Technically, Webflow leverages a modern tech stack including its proprietary CMS, Amazon AWS hosting and DNS services, and integrates marketing and analytics tools such as Marketo, Datadog, Intellimize, and Drift chat. The website is well-optimized for performance, mobile responsiveness, accessibility, and SEO, reflecting a mature digital infrastructure and strong technical implementation. From a security perspective, Webflow enforces HTTPS, employs multiple security headers, and uses a reputable domain registrar with consistent WHOIS data. However, DNSSEC is not enabled, and there is no public vulnerability disclosure policy or security.txt file, indicating areas for improvement. Privacy compliance is well addressed with clear privacy and cookie policies and GDPR adherence. Contact information is primarily available via forms and structured data, with no explicit public emails or phone numbers. Overall, Webflow presents a high level of professionalism, trustworthiness, and technical maturity. The platform is well-positioned in the market with strong branding, comprehensive service offerings, and a secure, performant website. Strategic recommendations include enabling DNSSEC, publishing a vulnerability disclosure policy, and enhancing incident response contact transparency to further strengthen security posture and trust.

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

3 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
  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

  • 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 occupies a strong market position as a pioneer in the no-code website builder space, targeting a diverse customer base from freelancers to large enterprises. Its SaaS business model generates revenue through subscription plans, enterprise contracts, and add-on services such as hosting and app integrations. The company demonstrates competitive advantages through its visual design capabilities, flexible CMS, and robust hosting infrastructure. Partnerships with marketing and analytics providers enhance its ecosystem. Growth indicators include a mature domain age, extensive customer logos and case studies, and active social media presence. Strategic observations highlight Webflow's focus on enterprise readiness, agency enablement, and continuous platform innovation including AI-powered features.

Security posture

Webflow exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and domain registration protections. The absence of DNSSEC is a minor gap but does not critically undermine security. No exposed sensitive data or vulnerable libraries were detected in the website content. Privacy policies and cookie consent mechanisms align with GDPR requirements. However, the lack of a public vulnerability disclosure program and incident response contact details suggests limited transparency in security incident handling. Overall, Webflow maintains a strong security culture appropriate for its enterprise clientele but should enhance disclosure and response readiness to meet evolving compliance standards such as NIS2.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing attacks.
  2. Publish a formal vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Provide explicit incident response contact channels such as security@ or abuse@ email addresses.
  4. Regularly review and audit third-party scripts and marketing tools for security vulnerabilities.
  5. Enhance transparency by listing security certifications and compliance attestations on the website.

Technical notes

Notes

The website is built on the Webflow platform utilizing its CMS and hosting capabilities backed by Amazon AWS infrastructure. It integrates multiple third-party marketing and analytics tools including Marketo, Datadog, Intellimize, and Drift chat, indicating a sophisticated digital marketing and monitoring setup. The site demonstrates excellent performance, mobile optimization, and accessibility features. The use of modern JavaScript libraries and asynchronous script loading contributes to fast page loads. Technical risks are minimal but include reliance on multiple external scripts which require ongoing security monitoring. The domain is well-managed with a reputable registrar and long history, supporting operational stability.
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.
