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

Tonsser is a well-established technology company founded in 2012, specializing in a football-focused mobile app platform designed for next-generation athletes. The platform offers comprehensive player profile building, performance tracking, and talent identification services, positioning itself as an innovative player in the sports technology market. The website reflects a professional and consistent brand image, supported by strong media coverage and community testimonials, enhancing its market credibility. Technically, the website is built on modern web technologies including Webflow CMS, Cloudflare DNS, and integrates key marketing and analytics tools such as Facebook Pixel and Google Analytics. It supports multiple languages via Weglot, ensuring accessibility to a broad international audience. The site demonstrates excellent performance, mobile optimization, and SEO practices, contributing to a positive user experience. From a security perspective, the site enforces HTTPS and employs domain transfer protection, but lacks DNSSEC and some recommended security headers. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. However, explicit security policies and incident response contacts are not publicly available, representing an area for improvement. Overall, Tonsser presents a low-risk profile with a mature domain and consistent business information. Strategic recommendations include enhancing DNS security, publishing security policies, and adding vulnerability disclosure mechanisms to further strengthen 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Tonsser operates in the sports technology sector, targeting amateur and next-gen football players globally. Its competitive advantage lies in combining community-driven data with talent identification algorithms, enabling players to showcase their skills and gain visibility with professional clubs. The business model revolves around a freemium app platform with potential revenue streams from talent scouting events and partnerships. The company has established a strong partnership ecosystem and media presence, indicating healthy growth and market penetration. The absence of direct contact information on the website suggests a focus on digital engagement and app-based interactions.

Security posture

The website demonstrates a solid security posture with HTTPS enforced and domain transfer protection enabled. No exposed sensitive data or vulnerable libraries were detected. However, the absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security indicates room for improvement. The lack of a published security policy or incident response contact reduces transparency in handling security incidents. Privacy compliance is well managed with GDPR-aligned policies and cookie consent. Overall, the security maturity is good but could be enhanced by adopting additional best practices and formalizing incident response procedures.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and prevent spoofing.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden web security.
  3. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and trust.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Regularly review and update privacy and cookie policies to maintain compliance with evolving regulations.

The website is hosted on Webflow with Cloudflare DNS, leveraging modern front-end technologies and third-party integrations for analytics and marketing. Performance is optimized with fast loading times and mobile responsiveness. The use of Weglot enables multilingual support, enhancing global reach. No technical debt or deprecated libraries were identified. Opportunities exist to improve DNS security and implement additional HTTP security headers. The technical infrastructure supports scalability and a high-quality 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.
