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

WunderTrading operates the website wunderbit.co, providing a platform for instant purchase of Bitcoin and over 100 other cryptocurrencies using credit and debit cards. The company targets both novice and experienced crypto investors seeking a fast, secure, and user-friendly buying experience. The platform emphasizes safety by partnering with accredited providers and enforcing AML and KYC policies. The website is well-branded, professionally designed, and offers multi-language support, enhancing its global reach. Technically, the site uses modern web technologies with Cloudflare DNS hosting, JavaScript, and CSS for a responsive and accessible user experience. SEO and social media integrations are well implemented, though some accessibility features could be improved. Performance is moderate, with room for optimization. Security posture is solid with HTTPS enforced and no direct storage of user assets, but lacks some advanced security headers and DNSSEC. Privacy compliance is mostly addressed with clear privacy and terms policies, but the absence of a cookie consent mechanism and incident response contacts are notable gaps. The domain is privacy protected but consistent with the business profile, and the domain age supports legitimacy. Tracking and marketing tools like Google Analytics, Facebook Pixel, and Trustpilot are used, indicating moderate user tracking. Overall, the website is credible, professional, and secure with minor areas for improvement in privacy compliance and security best practices. Strategic enhancements in these areas would strengthen trust and regulatory adherence.

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 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 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

WunderTrading positions itself as a key player in the crypto exchange sector, focusing on instant crypto purchases via credit cards. Its competitive advantage lies in ease of use, broad cryptocurrency support, and partnerships with trusted payment processors like Simplex. The business model revolves around transaction fees and commissions, targeting retail crypto buyers globally. The company leverages social media and Trustpilot reviews to build trust and brand awareness. Growth indicators include multi-language support and integration with automated trading services. The partnership ecosystem includes payment affiliates and crypto trading platforms, enhancing service offerings and market reach.

Security posture

The security maturity of wunderbit.co is moderate to good. HTTPS is enforced, and the platform does not hold user funds, reducing custodial risk. AML and KYC policies are publicly documented, indicating regulatory awareness. However, the lack of DNSSEC, missing security headers, and absence of a published vulnerability disclosure or incident response contacts represent compliance and operational gaps. Tracking scripts are present without a cookie consent banner, which may pose privacy compliance risks under GDPR. No critical vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is adequate but would benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and other privacy regulations.
  2. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  3. Add and configure security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  4. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide explicit incident response contact information (e.g., security@ or abuse@ email addresses) on the website.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS, and JavaScript, with Cloudflare providing DNS services. The site is mobile-optimized and supports multiple languages, enhancing accessibility and user reach. Performance is moderate, with potential improvements in load speed and accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The use of third-party scripts for analytics and affiliate marketing is evident, but no major technical debt or outdated libraries were detected. The absence of a CMS or framework mention suggests a custom or lightweight solution. Overall, the technical infrastructure is solid but could benefit from enhanced security configurations and privacy controls.
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.
