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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

  • Email security: did not complete in this scan.
  • 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

CBB Mobil operates in the telecommunications sector in Denmark, focusing on affordable mobile phones and subscription plans. Their competitive advantage lies in offering no-binding contracts and budget-friendly pricing. The business leverages partnerships with major marketing and analytics providers to optimize customer engagement and advertising effectiveness. The company targets individual consumers in Denmark, with a medium-sized operation indicated by the website's scale and technology use. The integration of Episerver CMS and Salesforce Marketing Cloud suggests a mature digital marketing strategy. No parent or subsidiary companies were identified. The company maintains a consistent brand presence and leverages customer reviews to build trust. The absence of explicit contact information on the main page may limit direct customer engagement but is mitigated by self-service portals and online support.

Security posture

The website demonstrates a good security posture with mandatory HTTPS and a detailed cookie consent mechanism supporting GDPR compliance. The use of multiple third-party services introduces complexity but is managed through transparent cookie categorization and consent options. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly found and should be implemented to enhance protection against common web attacks. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact reduces transparency and may impact trust among security-conscious users. Overall, the site balances user privacy and marketing needs effectively but should improve security header implementation and incident response readiness.

Recommendations

  1. Implement and verify comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  2. Publish a clear security policy and provide incident response contact information to improve transparency and user trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Develop and publish a terms of service page to clarify user rights and obligations.

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.
