The company targets business customers, distribution partners, ISPs, and carriers with a focus on secure, scalable, and innovative communication technologies. Their market position is that of a reputable regional provider with a strong emphasis on customer service and tailored business solutions. The website reflects a mature digital presence with a Joomla CMS platform, modern UIkit framework, and integration of advanced tools such as 3CX cloud telephony and Google reCAPTCHA for security. Privacy and cookie compliance are well implemented, with clear policies and consent mechanisms.

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. 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 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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

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

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

MK Netzdienste operates in the telecommunications sector, offering a comprehensive portfolio of services including internet connectivity, VPN solutions based on MPLS, IP telephony with cloud PBX options, and hosting services via their own data center in Frankfurt. Their business model is B2B focused, serving enterprises and ISPs with scalable and customizable solutions. The company holds certifications such as DIN EN 50600 for their data center and is recognized as a 3CX Titanium Partner, indicating strong vendor partnerships. They maintain a customer portal for self-service administration and emphasize long-term customer satisfaction through their MK-Promise service commitment. The company’s digital marketing includes tracking and analytics tools, but no aggressive advertising or affiliate programs are evident. Their client references include notable organizations, reinforcing credibility and market presence.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, DNSSEC enabled on the domain, and use of Google reCAPTCHA to protect forms from abuse. Cookie consent is actively managed with explicit user acceptance. No sensitive data is exposed in the HTML content. However, the absence of explicit security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS is a minor gap that could be addressed to enhance protection against common web attacks. There is no public security policy or incident response contact information, which could improve transparency and readiness. No vulnerabilities or suspicious activities were detected during analysis. Overall, the security maturity is good for a mid-sized telecommunications provider.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to harden the website against attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability disclosure.
  4. Regularly audit third-party scripts and tracking tools to ensure they comply with privacy regulations and do not introduce vulnerabilities.
  5. Enhance accessibility features and mobile optimization to improve user experience and compliance with standards.

Technical notes

Notes

The website is built on Joomla CMS with UIkit frontend framework and uses jQuery and other JavaScript libraries for interactivity. It integrates Google reCAPTCHA for bot protection and 3CX live chat for customer support. Analytics are handled via Piwik/Matomo and Wiredminds tracking scripts. The site is served over HTTPS with DNSSEC enabled, indicating a secure DNS configuration. Performance is moderate with room for optimization. The site is mobile responsive and SEO optimized with proper meta tags and Open Graph data. No major technical debt or deprecated technologies were detected, but security headers are missing which is a technical risk. Hosting provider details are not explicitly disclosed but the presence of a German data center is indicated. Overall, the technical infrastructure supports a professional and secure online presence.
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.
