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

6 findings rated critical or high. Fix these first.

  1. 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';…
  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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

    • High

      Weak DKIM Key

      DKIM selector 'mail' uses 440-bit key

      What to do: Use at least 2048-bit RSA keys for DKIM

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 business operates a referral marketing model to expand its customer base for telecommunications and energy products in Germany. The partnership with pso vertriebsprogramme GmbH indicates a specialized approach to sales programs. The market positioning is regional with a focus on customer satisfaction and incentives. The business model leverages customer advocacy to drive growth, with no direct sales on the site but referral links. The target audience includes end consumers seeking reliable internet, mobile, and energy solutions. The company maintains a consistent brand and clear communication, supporting growth through trusted referrals.

Security posture

The website enforces HTTPS and uses Usercentrics for cookie consent, indicating compliance with GDPR. However, no explicit security policy or incident response information is published, which could be improved. No security headers were detected in the HTML content, suggesting potential gaps in defense-in-depth. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of a vulnerability disclosure policy or security.txt file limits transparency for security researchers. Overall, the security posture is moderate but could be enhanced with additional published policies and technical headers.

Recommendations

  1. Publish a dedicated security policy page including incident response contacts.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities.

Technical notes

Notes

The website uses a modern JavaScript framework (Vue.js) with chunked scripts for performance optimization. Usercentrics is integrated for consent management, reflecting GDPR compliance. Hosting is via ewetel nameservers, consistent with telecommunications providers. The site is mobile optimized and SEO friendly with appropriate meta tags and Open Graph data. Performance is moderate, with potential for improvement in loading speed and accessibility. No CMS was detected, suggesting a custom or proprietary solution. The technical stack is modern but could benefit from enhanced security headers and performance tuning.
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.
