The DTB-Akademie is a well-established German educational institution specializing in training and continuing education for trainers, coaches, and professionals in sports, fitness, health, and related fields. Founded in 1995 and operated by the Deutscher Turner-Bund e.V., it offers a broad range of courses including fitness training, group fitness, health sports, dance, Pilates, yoga, and programs for children and the elderly. The website reflects a professional and consistent brand presence targeting sports professionals and educators across Germany. Technically, the website is built on Concrete CMS and employs standard web technologies such as jQuery, Google Tag Manager for analytics, and Usercentrics for consent management, indicating a moderate to good level of digital maturity. The site is mobile-optimized with good navigation and SEO practices, although some accessibility features could be improved. From a security perspective, the site uses HTTPS with a good SSL configuration and implements cookie consent mechanisms. However, explicit security headers and incident response information are not present, which could be enhanced to improve security posture. No vulnerabilities or suspicious content were detected. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR requirements. The domain appears legitimate with consistent business information, and the site links to multiple official partner domains related to the Deutscher Turner-Bund network.

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. 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
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL 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. 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. 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.

    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 23 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

DTB-Akademie occupies a strong niche in the German sports education market, leveraging over 30 years of experience and affiliation with the Deutscher Turner-Bund. Its competitive advantage lies in comprehensive, nationwide course offerings tailored to diverse target groups including sports trainers, fitness professionals, educators, and care workers. The business model is education-focused, generating revenue through course registrations and certifications. The partnership ecosystem includes regional DTB centers and related organizations, enhancing reach and credibility. Growth indicators include continuous program updates and digital presence enhancements. Strategic observations suggest opportunities to expand digital services and improve security transparency.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent management, and no visible exposure of sensitive data. The absence of explicit security headers (e.g., CSP, HSTS) and lack of published incident response contacts or security policies represent gaps that could be addressed to strengthen defenses and compliance. GDPR compliance is evident through privacy and cookie policies. No critical vulnerabilities or suspicious activities were identified, indicating a low risk profile. Enhancing security documentation and implementing security headers would further improve resilience and trust.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  2. Publish a security policy and incident response contact information to improve transparency and readiness.
  3. Introduce a security.txt file to facilitate vulnerability disclosures and responsible reporting.
  4. Enhance accessibility features to improve compliance with standards and user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize tracking footprint.

Technical notes

Notes

The website is powered by Concrete CMS, a mature content management system, and uses jQuery along with Google Tag Manager and Usercentrics for analytics and consent management. The site is mobile responsive with good SEO meta tags and structured navigation. Performance is moderate, with potential improvements in loading speed and accessibility. The hosting provider is inferred from nameservers as Your-Server.de, a known German hosting provider. The technical stack is stable but could benefit from modernization in JavaScript frameworks and enhanced security configurations. Overall, the infrastructure supports the business needs effectively with room for optimization.
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.
