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

The Hermann Hesse Schule Aalen is a specialized educational institution in Germany focusing on special education needs, particularly in learning and emotional-social development. The website serves as an informational portal for students, parents, and educators, detailing the school's services including inclusive education and early childhood support. The institution appears to be a small-sized regional school with a clear educational mission but limited digital sophistication. Technically, the website uses basic HTML, CSS, and JavaScript with legacy libraries such as jQuery. There is no evidence of a modern CMS or advanced frameworks. Mobile optimization and accessibility are minimal, and SEO practices are basic. The site lacks structured data and social media integration, indicating a low level of digital maturity. From a security perspective, the site does not demonstrate strong security posture. There is no visible HTTPS confirmation in the provided data, no security headers, and no privacy or cookie policies, which are critical for GDPR compliance in Germany. Contact information is limited to a physical address, with no emails or phone numbers clearly provided. No incident response or data protection officer contacts are found, indicating gaps in security and compliance readiness. Overall, the website is functional for its educational purpose but requires significant improvements in security, privacy compliance, and technical modernization to enhance trustworthiness and user experience.

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

11 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 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

  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"

    • 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

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

The Hermann Hesse Schule Aalen operates as a public special education school serving children with learning and emotional-social development needs. Its market position is regional, focusing on inclusive education and early intervention services. The business model is that of a public educational institution, likely funded by government sources. The target customers are students requiring special education, their families, and educational professionals. The school offers key services such as specialized learning programs, social-emotional development support, early childhood special education, and school kindergarten services. There is no indication of commercial revenue streams or partnerships. The website content and domain registration align with the institution's educational mission, supporting legitimacy and credibility.

Security posture

The current security posture of the website is basic and lacks several best practices. The absence of HTTPS confirmation in the provided data is a critical issue, as secure communication is mandatory for any modern website, especially in the education sector handling potentially sensitive data. No security headers such as Content-Security-Policy or X-Frame-Options are detected, increasing risk exposure. There are no visible forms or input fields, reducing attack surface but also limiting user interaction. The lack of privacy and cookie policies indicates non-compliance with GDPR requirements, which is a significant compliance gap. No incident response or security contact information is provided, limiting the ability to report or respond to security incidents. Overall, the site requires urgent improvements in encryption, security headers, and compliance documentation to reduce risk.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate to secure all communications.
  2. Add comprehensive privacy and cookie policies to comply with GDPR and inform users.
  3. Include security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Provide clear contact information including emails and phone numbers for general and security-related inquiries.
  5. Improve mobile responsiveness and accessibility to enhance user experience and compliance.

Technical notes

Notes

The website is built using basic HTML, CSS, and JavaScript with jQuery. There is no evidence of a modern CMS or advanced frameworks. The site uses multiple CSS files and scripts, some of which appear legacy or custom (e.g., coin-slider). The site lacks structured data (JSON-LD) and Open Graph metadata, limiting SEO and social media integration. Mobile optimization is minimal, with some conditional CSS for Android and IE browsers. Performance is moderate but could be improved by modernizing the tech stack and optimizing assets. Hosting details are not explicit, but WHOIS name servers indicate use of iserv.eu, a provider for educational institutions. Overall, the technical infrastructure is functional but dated, with opportunities for modernization and improved performance.
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.
