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

4 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

      Domain Expires Soon

      Domain expires in 9 days

      What to do: Renew domain registration before expiration

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

CUX occupies a niche in the digital analytics market by combining technology with human expertise, differentiating itself from self-service analytics tools. Its business model integrates SaaS offerings with personalized consulting, targeting medium to large enterprises across various industries. The company’s partnerships, such as with HubSpot for meetings, and case studies with major brands, underscore its market penetration and credibility. Revenue streams likely include subscription fees and consulting services. The multi-office presence suggests growth ambitions and regional diversification. The company’s transparent GDPR compliance and audit success enhance its competitive advantage in privacy-conscious markets.

Security posture

CUX exhibits a mature security posture with encryption in transit and at rest, GDPR compliance baked into platform design, and role-based access controls with audit trails. The platform’s lightweight implementation reduces attack surface and operational risks. However, the lack of DNSSEC and absence of a published vulnerability disclosure or incident response contact limit transparency and responsiveness to emerging threats. No critical security headers were detected in the HTML, which could be improved. Overall, the security practices align well with enterprise expectations but could benefit from formalized disclosure policies and enhanced DNS security.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file and vulnerability disclosure policy to improve transparency and incident response readiness.
  3. Implement a cookie consent banner/mechanism to ensure full GDPR compliance regarding user tracking.
  4. Add security HTTP headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the web application.
  5. Provide explicit incident response contact channels (e.g., security@ or abuse@ emails) to facilitate reporting and handling of security issues.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging server-side rendering and optimized asset loading for fast performance. CSS Modules are used for scoped styling, and fonts are preloaded for improved UX. Google Tag Manager is integrated for analytics. Hosting is via OVH SAS, a reputable European provider. The site is mobile-optimized with responsive images and viewport settings. No CMS is detected, indicating a custom or proprietary solution. The technical implementation is robust, with good SEO metadata and structured data (JSON-LD) for enhanced search engine understanding. Opportunities exist to improve security headers and DNS configurations.
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.
