Technically, the website is built on WordPress with a modern tech stack including jQuery and various plugins for user interaction, cookie compliance, and content management. Hosting appears to be with a German provider, and the site demonstrates good mobile optimization and SEO practices.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

    • 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';…

  3. 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

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 · found on this site
  • 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

K-TEL Communications GmbH operates in the telecommunications sector, focusing on consulting and brokerage services for business IT infrastructure. Their market positioning is that of an experienced independent advisor with a broad service portfolio including cloud, mobile, data center, and smart IoT solutions. The business model revolves around consulting, service brokerage, and managed services. Their target customers range from large global players to startups, indicating a flexible approach to client size and needs. The company maintains partnerships and a partner portal, indicating an ecosystem approach. Growth indicators include recent references and active social media presence. The company emphasizes transparency, experience, and technical expertise as competitive advantages.

Security posture

The security maturity of the website is good, with HTTPS enforced and GDPR-compliant cookie consent implemented. The absence of explicit security headers like CSP or HSTS is a minor gap. No incident response or vulnerability disclosure information is publicly available, which could be improved to enhance readiness and transparency. No exposed sensitive data or vulnerable libraries were detected. The use of reputable WordPress plugins and regular updates is implied. Overall, the security posture supports business continuity and data protection but could benefit from formalized incident response and disclosure policies.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a dedicated incident response page or contact email (e.g., security@ktel.de) to improve transparency and readiness for security incidents.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update all third-party plugins and scripts to mitigate risks from vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance with evolving standards.

Technical notes

Notes

The website is built on WordPress 6.8.3 with a modern JavaScript stack including jQuery and Owl Carousel for UI components. It uses several plugins for contact forms, cookie consent (Complianz), download management, and lightbox functionality. Hosting is likely provided by a German hosting provider (your-server.de). Performance is moderate with good mobile optimization and SEO practices. The site uses HTTPS with a valid SSL certificate. Some technical debt is indicated by legacy jQuery migrate usage and lack of advanced security headers. Opportunities exist to modernize scripts and enhance security configurations to reduce risk and improve performance.
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.
