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

internetlehrer GmbH is a specialized e-learning service provider based in Germany, operating since 2003. The company focuses on developing learning modules, blended learning scenarios, and virtual classroom integrations, leveraging open source technologies such as ILIAS. Their market position is that of an established niche player and ILIAS Premium Partner, serving education professionals and institutions with tailored e-learning solutions. The website reflects a professional and consistent brand image with clear contact information and relevant content in German. Technically, the website is built on WordPress 6.1.9 with common libraries like jQuery and Cycle2 for slideshows. Hosting appears to be with 1&1 IONOS, indicated by the presence of their WordPress assistant plugin. The site is moderately performant, mobile-optimized, and uses HTTPS with a good SSL configuration. However, it lacks advanced security headers and a cookie consent mechanism, which are important for GDPR compliance. From a security perspective, the site enforces HTTPS and does not expose sensitive data or use vulnerable libraries. There is no evidence of a published security policy or incident response contacts, which could be improved. No WAF or blocking mechanisms are detected, and the WHOIS data is consistent with the business claims, indicating legitimacy. Privacy compliance is partial due to the absence of cookie consent. Overall, the website is trustworthy and professional but could enhance its privacy and security posture by implementing cookie consent, security headers, and publishing security policies. These improvements would strengthen compliance and user trust while maintaining the solid business credibility already established.

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

8 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

internetlehrer GmbH operates in the education sector, providing specialized e-learning services including content development, blended learning, and technical support. Their competitive advantage lies in their long-standing experience since 2003 and status as an ILIAS Premium Partner, which positions them well within the e-learning niche. The business model is B2B, targeting educational institutions and professionals seeking customized e-learning solutions. Revenue streams likely derive from service contracts, training, and technical development projects. The company maintains a focused partnership ecosystem around open source e-learning technologies. Growth indicators include active blog content and continuous technical updates. Strategic observations suggest opportunities to expand digital marketing and enhance privacy compliance to attract broader clientele.

Security posture

The current security maturity level is moderate. The website uses HTTPS with a strong SSL configuration, which is a critical security baseline. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to certain web-based attacks. There is no visible incident response or security policy, which limits transparency and preparedness. GDPR compliance is partial due to missing cookie consent mechanisms. The security culture appears basic but can be improved by adopting best practices and publishing clear security documentation. No critical vulnerabilities or malware indicators were found.

Recommendations

  1. Implement a cookie consent banner to ensure GDPR compliance and inform users about cookie usage.
  2. Add essential security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit and update WordPress plugins and scripts to mitigate potential vulnerabilities.
  5. Consider establishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website is built on a modern WordPress CMS version 6.1.9, utilizing standard libraries such as jQuery and Cycle2 for interactive elements. The presence of the 1and1 WordPress assistant plugin suggests hosting with 1&1 IONOS. The site loads external resources like Google Fonts and Font Awesome for styling and icons. Performance is moderate with mobile optimization rated good. Accessibility features are basic, with room for improvement. SEO optimization is basic, with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. The technical infrastructure is stable but could benefit from enhanced security headers and privacy compliance mechanisms to reduce technical debt and improve resilience.
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.
