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

Lehrkraft Digital operates an e-commerce platform specializing in Apple products and educational licenses targeted at teachers. The website is built using modern technologies such as Flutter for frontend, Supabase for backend services, and Intercom for customer communication. The business model focuses on providing discounted Apple products and educational licenses, catering specifically to the education sector. The site presents a niche market position with a clear target audience of educators and schools. From a technical perspective, the website leverages a modern tech stack with Flutter and Supabase, hosted likely on Vercel, ensuring a responsive and performant user experience. However, the site lacks visible security headers and published privacy or cookie policies, which are critical for compliance and user trust. The use of JWT tokens and session management indicates some level of security maturity, but the absence of WHOIS transparency and DNSSEC reduces overall trust. Security posture is moderate with no immediate vulnerabilities detected in the provided content, but improvements are needed in security headers, privacy disclosures, and WHOIS data completeness. The site does not exhibit any WAF or blocking mechanisms, and content is fully accessible and safe for general audiences. Overall, Lehrkraft Digital shows promise as a specialized e-commerce platform but should prioritize enhancing transparency, compliance, and security best practices to improve trust and reduce risk.

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. 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Lehrkraft Digital targets a specialized niche within the education sector, focusing on teachers and educational institutions seeking Apple products with educational discounts and Westermann licenses. The business model is direct-to-consumer e-commerce with a focus on educational discounts, likely generating revenue through product sales and licensing agreements. The use of modern cloud-based backend services like Supabase suggests a lean operational model with scalable infrastructure. The lack of visible partner or subsidiary domains indicates a standalone operation. Growth potential exists within the education technology market, but the absence of detailed company information and contact data limits external trust and partnership opportunities.

Security posture

The website demonstrates a moderate security maturity level with the use of HTTPS, JWT-based authentication for Intercom integration, and session management via Supabase. However, the absence of critical security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is a notable gap. The incomplete WHOIS data and missing DNSSEC reduce domain trustworthiness and transparency. No explicit privacy or cookie policies are published, which is a compliance risk under GDPR. Incident response and security policy information are not available, indicating a lack of formalized security governance. Overall, the security posture is functional but requires enhancements in policy transparency, header implementation, and domain registration completeness.

Recommendations

  1. Implement comprehensive privacy and cookie policies to ensure GDPR compliance and improve user trust.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Complete WHOIS registration details and enable DNSSEC to improve domain transparency and trustworthiness.
  4. Publish clear contact and incident response information to facilitate security reporting and improve organizational transparency.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries and services.

Technical notes

Notes

The website is built using Flutter, a modern UI toolkit, compiled to JavaScript for web deployment. It uses Supabase as a backend-as-a-service platform for authentication and data management, and Intercom for customer engagement and support. Hosting appears to be on Vercel, indicated by the presence of Vercel insights scripts. The site is moderately performant with good mobile optimization and basic accessibility features. SEO optimization is basic, relying on meta tags and Open Graph data but lacking structured data like JSON-LD. There is no detected CMS, suggesting a custom or framework-based build. Technical risks include missing security headers and incomplete WHOIS data, which could impact trust and security posture.
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.
