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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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 · found on this site
  • 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 company targets German-speaking e-commerce entrepreneurs seeking to differentiate their shops and increase profitability without engaging in price wars. Their business model centers on premium coaching services, including online learning modules and personal mentoring. The brand is well-positioned with over 15,000 shops served and 500+ positive reviews, supported by partnerships such as Shopware. The absence of direct contact details on the site suggests a focus on lead generation via scheduled consultations. The company emphasizes exclusivity and quality, offering a 100% satisfaction guarantee to reduce buyer risk.

Security posture

The website employs HTTPS and a comprehensive cookie consent banner compliant with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, and security.txt files indicates room for improvement in transparency and readiness. Security headers like Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection against common web attacks. Overall, the security posture is good but could be strengthened with additional best practices and published policies.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Add a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Provide clear business contact information including email and phone to enhance trust and compliance.
  5. Regularly audit third-party scripts and tracking tools to ensure privacy compliance and minimize tracking footprint.

Technical notes

Notes

The website is built on the Shopware platform using modern HTML5, CSS3, and JavaScript with jQuery 3.6.0. It includes a cookie consent solution from TC-Tools and integrates Google Analytics for tracking. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph tags. Performance is moderate with lazy loading for images and videos. Accessibility is basic but could be improved with ARIA roles and better keyboard navigation support. No major technical debt or outdated libraries were detected, indicating a well-maintained technical infrastructure.
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.
