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

Sponsoo GmbH operates Europe's largest online marketplace for sports sponsorship, connecting thousands of athletes, teams, clubs, associations, and events with sponsors across more than 300 sports disciplines. The platform facilitates profile creation, offer listings, and supports deal negotiation, targeting athletes and companies seeking sponsorship opportunities. The company is positioned as a leading player in the European sports sponsorship market with a medium-sized business footprint and a founding year of 2014. Technically, the website employs modern web technologies including AngularJS, Google Tag Manager, Google Analytics, and Facebook Pixel for analytics and marketing. Hosting is provided by netcup, a reputable provider. The site is mobile-optimized with good SEO practices and a professional design, though accessibility features are basic. From a security perspective, the site uses HTTPS and implements CSRF tokens in forms, but lacks visible security headers and explicit security policies. Privacy compliance is partially addressed with a comprehensive GDPR privacy policy but lacks a cookie consent mechanism. No vulnerability disclosure or incident response contacts are published. Overall, the website is professional, trustworthy, and safe for general audiences. Strategic improvements in security headers, cookie consent, and transparency around security policies would enhance the security posture and compliance standing.

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. 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 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';…

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's market positioning as the largest European sports sponsorship marketplace provides a competitive advantage by aggregating a wide variety of sports entities and sponsors. The business model relies on facilitating sponsorship deals via an online platform, generating revenue likely through fees or premium services. The target customers include athletes, sports teams, clubs, associations, sponsors, companies, agencies, and brands. Growth indicators include multiple regional domains, media coverage, and partnerships with European and German funding agencies. The partnership ecosystem includes recognized media outlets and government bodies, enhancing credibility and reach. The company maintains a professional online presence with active social media channels and a comprehensive portfolio showcasing real athlete profiles.

Security posture

The current security maturity level is moderate. The use of HTTPS and CSRF tokens in login forms are positive indicators. However, the absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces protection against common web attacks. No published security policy or incident response contacts limit transparency and preparedness. GDPR compliance is partially met with a privacy policy but lacks cookie consent mechanisms. No vulnerability disclosure or security.txt files were found, indicating limited formal vulnerability management. The security culture appears functional but could benefit from enhanced transparency and technical controls to reduce risk.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  2. Introduce a cookie consent banner/mechanism to comply fully with GDPR and ePrivacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Establish a vulnerability disclosure program and publish a security.txt file to encourage responsible reporting and improve security posture.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website infrastructure is built on a modern JavaScript framework (AngularJS) with integration of third-party analytics and marketing tools such as Google Tag Manager, Google Analytics, and Facebook Pixel. Hosting is managed by netcup, a known provider. The site is mobile-optimized and includes multimedia content such as videos and animated progress circles. Performance is moderate, with asynchronous loading of scripts to improve page load times. Technical debt is minimal but the use of AngularJS (an older framework) suggests potential modernization opportunities. SEO is well addressed with meta tags and alternate language links. Technical risks include lack of security headers and incomplete privacy compliance mechanisms.
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.
