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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

  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 operates in the technology sector as an essential entity providing a no-code platform for website creation and management. Its business model is SaaS-based, generating revenue through subscriptions and enterprise services. The company targets diverse customer segments including freelancers, agencies, startups, and large enterprises. Webflow's competitive advantage lies in its visual design capabilities combined with powerful CMS and hosting features. The partnership ecosystem includes integrations with major marketing and analytics platforms. Growth indicators include new product features like AI enhancements and Webflow Cloud. Strategic observations highlight Webflow's focus on expanding enterprise adoption and enhancing user experience through continuous innovation.

Security posture

Webflow exhibits a strong security posture with enforced HTTPS, domain registration locks, and use of reputable hosting and CDN providers. The website includes security and analytics scripts loaded asynchronously to minimize risk. However, DNSSEC is not enabled, which could improve DNS security. There is no publicly available incident response or vulnerability disclosure policy, which is a gap in transparency and security readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy policies and cookie consent mechanisms are in place, supporting GDPR compliance. Overall, Webflow maintains a secure environment appropriate for its enterprise clientele but could enhance security communication and DNS protections.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Publish a clear vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  3. Enhance incident response transparency by providing contact channels for security issues.
  4. Regularly review and update third-party scripts to mitigate risks from external dependencies.
  5. Continue investing in privacy compliance and user consent mechanisms to maintain regulatory adherence.

Technical risks are minimal, with no broken elements or errors detected. Opportunities exist to further modernize DNS security and enhance security policy disclosures.
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.
