Medium risk. 7 critical or high findings in GDPR outside view and Security headers.

Security score

53/100

Risk levelMedium

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

Freenet DLS GmbH operates a comprehensive German telecommunications website offering mobile phone tariffs, devices, and related digital services. The company targets German consumers seeking flexible mobile plans and devices, positioning itself as a significant player in the German telecom market. The website features structured data with detailed company information and social media presence, supporting brand credibility and customer engagement. Technically, the site employs modern JavaScript frameworks, Cloudflare CDN, and personalization tools like Kameleoon, but suffers from critical SSL/TLS misconfigurations that undermine secure HTTPS access. Security headers are partially implemented, but the lack of a valid SSL certificate and disabled TLS protocols represent major vulnerabilities. Privacy and cookie policies are not detected, indicating compliance gaps. Overall, the site is functional and professionally designed but requires urgent security improvements to protect user data and comply with regulations.

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

7 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

  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

  • 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

The company leverages a broad product portfolio including mobile tariffs without and with devices, internet services, and digital content subscriptions. Its business model combines direct sales and online account management, supported by a network of physical shops and appointment scheduling. The presence of multiple MX records and SPF configurations indicates robust email infrastructure. The partnership with freenet-internet.de suggests a broader ecosystem of related services. Marketing and analytics tools such as Google Tag Manager and Kameleoon enable data-driven customer engagement. However, the absence of explicit privacy and terms pages may impact customer trust and regulatory compliance.

Security posture

The website's security posture is weak due to the absence of a valid SSL certificate and disabled TLS protocols, exposing users to potential data interception and man-in-the-middle attacks. While Cloudflare provides CDN and some security headers like HSTS, inconsistencies exist between header presence and SSL configuration. No advanced security policies or incident response contacts are published. The site does not implement OCSP stapling or session resumption, reducing TLS performance and security. No vulnerability disclosure or security.txt files are found, limiting transparency. These issues represent critical risks that must be addressed to safeguard customer data and maintain trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and configure strong cipher suites.
  3. Implement and verify consistent security headers including HSTS with includeSubDomains.
  4. Publish comprehensive privacy and cookie policies with clear consent mechanisms to ensure GDPR compliance.
  5. Establish a vulnerability disclosure policy and provide incident response contact information.
  6. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  7. Enhance accessibility features and optimize performance to improve user experience.
  8. Maintain clear and accessible contact information and legal disclosures to strengthen business credibility.

Technical notes

Notes

The website uses a modern frontend stack with jQuery 3.6.0, AngularJS controllers, and custom web components hosted on AWS S3 buckets. Cloudflare provides CDN and DNS services, with DNS records well configured including SPF for email protection. Google Tag Manager and Kameleoon are used for analytics and personalization. However, the SSL/TLS configuration is critically flawed with no valid certificate and no TLS protocols enabled, severely impacting security and user trust. Performance metrics are missing or zero, indicating potential measurement gaps. The site is mobile optimized and SEO friendly with proper meta tags and structured data. Technical debt is moderate, with opportunities to modernize security and improve compliance documentation.
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.
