Their services include precise event planning, modern didactics, certification support, and networking opportunities, targeting medical professionals primarily in Germany. The website reflects a professional and consistent brand image with clear navigation and relevant content tailored to its audience. Technically, the website is built on WordPress with a modern tech stack including jQuery, MasterSlider, and Ninja Forms. Hosting appears to be managed via 1&1 IONOS, indicated by the nameservers. The site demonstrates good mobile optimization and moderate performance, with proper SEO and accessibility features. Cookie consent mechanisms are implemented, supporting GDPR compliance. From a security perspective, the site uses HTTPS with excellent SSL configuration and employs best practices such as nonce usage in AJAX calls and cookie consent banners. However, it lacks explicit security headers and incident response contact information, which are recommended for enhanced security posture. No vulnerabilities or exposed sensitive data were detected. Overall, diaplan.de presents a trustworthy and professional online presence with a solid security baseline and compliance with privacy regulations. Strategic improvements in security headers and incident response transparency could further strengthen its security and trustworthiness.

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

10 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

  2. 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB 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

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

diaplan GmbH occupies a niche market in medical continuing education and event management within Germany. Its competitive advantage lies in offering a neutral and comprehensive platform for medical professionals and institutions to exchange knowledge and organize certified educational events. The business model is service-oriented, focusing on event planning, didactic support, and certification facilitation. The company collaborates with reputable medical associations, enhancing its credibility and market reach. The target customers are clinics, doctors, and medical associations seeking professional continuing education solutions. The website's partnership ecosystem includes several medical associations, indicating strong industry ties. Growth indicators include a well-maintained website with updated content and multiple service offerings. The company maintains a consistent brand and professional communication, supporting its market position as a trusted provider in healthcare education.

Security posture

The security maturity of diaplan.de is moderate to good. The website enforces HTTPS with strong SSL configuration, ensuring encrypted communications. Cookie consent is implemented, aligning with GDPR requirements. The use of nonce tokens in AJAX requests indicates attention to secure form handling. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to certain web-based attacks. No incident response or security contact information is provided, limiting transparency and readiness for vulnerability reporting. No vulnerable libraries or exposed sensitive data were identified in the HTML content. Overall, the site demonstrates a baseline security posture suitable for its business but would benefit from enhancements in security headers and incident response mechanisms to improve resilience and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a security policy or incident response contact page with dedicated email addresses (e.g., security@ or abuse@) to facilitate vulnerability reporting and improve transparency.
  3. Regularly audit and update all WordPress plugins and themes to minimize risks from known vulnerabilities.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Consider adding a security.txt file to standardize vulnerability disclosure and improve trust with security researchers.

Technical notes

Notes

The website is built on a WordPress CMS platform using a combination of popular plugins such as MasterSlider for responsive image sliders, Ninja Forms for file uploads, and TablePress Premium for table management. The theme used is a child theme of Impreza, indicating customization. The site loads jQuery and other JavaScript libraries to support interactive features. Hosting is likely provided by 1&1 IONOS, inferred from the nameservers. Performance is moderate with some optimization opportunities, especially in loading times and accessibility. The site is mobile optimized with responsive design and viewport settings. SEO is supported by proper meta tags, Open Graph tags, and canonical URLs. The technical stack is modern but could benefit from additional security hardening and performance tuning to reduce technical debt and improve user experience.
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.
