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

JoinSports.de is a German-based online platform focused on enabling users to book sports activities easily within their region. The website leverages modern web technologies including Vue.js, Tailwind CSS, and integrates third-party services such as Stripe for payment processing and Intercom for customer engagement. The technical infrastructure is hosted on Amazon AWS, indicating a professional hosting environment. However, the website content is primarily client-side rendered, with minimal static HTML content available, which may impact SEO and accessibility. Security-wise, HTTPS is used as inferred from included scripts, but explicit security headers are missing, and no privacy or cookie policies are present, indicating gaps in compliance and security best practices. Overall, the site presents a moderate security posture with room for improvement in privacy compliance and transparency.

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

8 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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';…

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 business operates in the sports booking sector targeting general consumers interested in local sports offerings. The platform's business model likely revolves around facilitating bookings and payments online, possibly earning revenue via commissions or service fees. The use of Stripe suggests a focus on secure payment processing. The absence of detailed company information, contact details, or legal disclosures on the site limits the ability to fully assess business credibility. The integration of Intercom indicates an emphasis on customer support and engagement. The platform appears to be a small to medium-sized enterprise with a digital-first approach but lacks comprehensive public-facing business information.

Security posture

The website demonstrates a basic security posture with HTTPS usage and no visible exposed sensitive data. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. The absence of privacy and cookie policies, as well as incident response contacts, indicates compliance gaps with GDPR and other regulations. The use of third-party scripts like Stripe and Intercom introduces dependencies that require careful management to avoid vulnerabilities. No critical vulnerabilities or malware indicators were detected in the provided content. Overall, the security maturity is moderate but requires enhancements in policy transparency and technical safeguards.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web vulnerabilities.
  3. Provide clear contact information including support and incident response channels to improve business credibility and security readiness.
  4. Conduct regular security audits of third-party integrations and update dependencies to mitigate potential vulnerabilities.
  5. Improve SEO and accessibility by adding server-side rendered content or prerendering to enhance content discoverability and user experience.

Technical notes

Notes

The website is built as a modern single-page application using Vue.js and styled with Tailwind CSS, indicating a contemporary front-end approach. It integrates Stripe for payment processing and Intercom for customer communication, showing a reliance on trusted third-party services. Hosting is on Amazon AWS, as evidenced by the DNS name servers. The site uses MapLibre GL for map rendering and Swiper for interactive sliders. Performance appears moderate with deferred JavaScript loading and asynchronous script inclusion. However, the lack of server-side rendered content may impact SEO and accessibility. No CMS was detected, suggesting a custom or headless architecture. Overall, the technical stack is modern and scalable but could benefit from enhanced SEO and security configurations.
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.
