0–100, higher is better. How it is calculated

Vereinsflieger.de is a specialized online platform providing club management software tailored for flight sport clubs in Germany. The website offers services including online club administration, flight logging, seminar scheduling, and integrations with flight school solutions and electronic logbooks. The target audience primarily consists of flight clubs, flight instructors, and aviation enthusiasts within the German-speaking market. The business operates as a small-sized entity focusing on a niche transportation sector with a SaaS business model. Technically, the website is built with standard HTML, CSS, and JavaScript, hosted with DNS services from GoDaddy. The site is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, the site uses password masking and cryptographic salts in login forms but lacks visible security headers and cookie consent mechanisms, which are recommended for GDPR compliance. No blocking or WAF mechanisms were detected, and the domain registration appears consistent with the business purpose. Overall, the website demonstrates a good balance of content quality, technical implementation, and business credibility, with room for improvement in security and privacy compliance.

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

5 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
  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network 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
  • 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 company positions itself as a niche provider of flight club management software in Germany, leveraging partnerships with related flight school and flight logging services. Its competitive advantage lies in specialized features tailored to aviation clubs and integration with electronic flight logbooks and seminar management. The business model is subscription-based SaaS targeting small to medium-sized aviation clubs and schools. The presence of social media links and a public seminar calendar indicates active community engagement. The company appears to have a focused ecosystem of partners enhancing its service offering. Growth potential exists through expanding integrations and improving compliance and security features.

Security posture

The website shows moderate security maturity with secure password input practices and cryptographic elements in forms. However, it lacks critical security headers such as Content-Security-Policy and HSTS, and no cookie consent mechanism is present, which is a GDPR compliance gap. There is no published security policy or incident response contact information, limiting transparency in security governance. The absence of visible analytics or tracking scripts reduces privacy risks but also limits insight into user behavior. Overall, the security posture is adequate for a small SaaS provider but requires enhancements to meet best practices and regulatory requirements.

Recommendations

  1. Implement HTTPS with strong SSL/TLS configuration and verify certificate validity.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Deploy a cookie consent banner and explicit cookie policy to comply with GDPR.
  4. Publish a security policy and incident response contact information to improve transparency.
  5. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website uses a simple technology stack with HTML5, CSS, and JavaScript, without detectable CMS or advanced frameworks. Hosting is managed via GoDaddy DNS services. The site is mobile responsive and has a clear navigation structure. Performance is moderate with no evident broken elements. However, the lack of advanced SEO and accessibility features suggests room for technical modernization. No analytics or tracking scripts were detected, which may limit marketing insights but improves privacy. The login form includes cryptographic salts indicating some security awareness. Overall, the technical infrastructure is stable but basic, suitable for a small niche SaaS provider.
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.
