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

Sponsoo GmbH operates an online marketplace platform specializing in sports sponsorship, connecting athletes, teams, clubs, associations, and sports events with potential sponsors and brands. The platform offers profiles and sponsorship opportunities, facilitating deal-making and implementation support. The company positions itself as a leading marketplace in this niche, targeting a broad audience within the sports and marketing sectors. The website is professionally designed, multilingual, and includes various trust signals such as media mentions and support from European institutions. Technically, the website employs modern web technologies including AngularJS, Google Tag Manager, Google Analytics, and Facebook Pixel for marketing and analytics purposes. The site uses HTTPS with secure login forms and CSRF protection, but lacks some security headers and cookie consent mechanisms. Performance is moderate with good mobile optimization and basic accessibility features. From a security perspective, the site demonstrates good practices such as encrypted connections and secure authentication flows. However, the absence of security headers, cookie consent, and vulnerability disclosure policies indicates room for improvement. The missing WHOIS data for the domain is a notable concern, potentially impacting trust and legitimacy assessments. Overall, Sponsoo presents a credible and professional online presence with a solid business model and market position. Strategic improvements in security posture, privacy compliance, and domain registration transparency are recommended to enhance trust and 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. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  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

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Sponsoo GmbH operates in the sports sponsorship marketplace sector, offering a platform that connects sportspeople and organizations with sponsors. The business model is based on facilitating sponsorship deals through profile listings and targeted matching. The company targets athletes, teams, clubs, associations, events, and sponsors including corporates and agencies. The platform's competitive advantage lies in its extensive portfolio covering over 300 sports and its support from reputable media and European institutions. Revenue streams likely include fees or commissions on sponsorship deals. The company shows growth indicators through a broad international presence and multilingual websites. Partnerships with European Commission and German federal agencies enhance credibility. The company maintains a strong social media presence and investor relations, indicating a mature business operation.

Security posture

The website employs HTTPS with secure login forms protected by CSRF tokens and integrates OAuth login via Facebook. Tracking technologies include Google Analytics and Facebook Pixel, which are standard but require proper privacy disclosures. No security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to certain web attacks. The absence of a cookie consent mechanism and vulnerability disclosure policy indicates gaps in GDPR compliance and security transparency. No exposed sensitive data or vulnerable libraries were identified in the HTML source. Incident response and security policy information are not publicly available, limiting assessment of readiness. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, policies, and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR and improve user privacy transparency.
  3. Publish a security policy and incident response contact information to demonstrate security maturity and readiness.
  4. Establish a vulnerability disclosure program and consider adding a security.txt file to facilitate responsible reporting.
  5. Verify and update WHOIS domain registration information to ensure transparency and trustworthiness.

Technical notes

Notes

The website uses a modern technology stack with AngularJS for frontend interactivity, Google Tag Manager and Google Analytics for marketing analytics, and Facebook Pixel for tracking. The site includes HTML5 video and canvas elements for dynamic content. The login form uses CSRF tokens and supports OAuth login via Facebook, Google+, and Xing. The site is mobile optimized with responsive design and basic accessibility features. Performance is moderate, with some JavaScript-heavy elements that may impact load times. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the HTML source. The site lacks some modern security headers and cookie consent mechanisms, which are technical debt areas to address.
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.
