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

The Sisi-Schloss Aichach website represents a government-operated cultural heritage site focused on the historic water castle in Aichach-Unterwittelsbach, Germany. It provides detailed visitor information, exhibitions related to Kaiserin Elisabeth, and cultural events. The site targets tourists and local visitors interested in history and culture. The business model is public sector cultural tourism, with Stadt Aichach as the owner and operator. Technically, the website uses a moderate technology stack including jQuery, ikiss CMS, and accessibility tools. It is mobile optimized and includes SEO and accessibility features. Performance is moderate, with room for improvement in security headers and DNSSEC implementation. Security posture is basic but adequate, with HTTPS enabled and cookie consent mechanisms in place. However, the absence of DNSSEC and security headers suggests potential areas for enhancement. No incident response or security policy information is publicly available. Overall, the website is trustworthy, professionally maintained, and compliant with GDPR requirements. The domain registration aligns well with the official city ownership, reinforcing legitimacy. Strategic improvements in security and transparency could further strengthen the site's posture.

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

4 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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 384-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

The website positions itself as a regional cultural heritage and tourism attraction under the governance of Stadt Aichach. Its competitive advantage lies in its official backing and focus on Kaiserin Elisabeth's legacy. Revenue streams likely derive from visitor admissions, events, and cultural programming. The target customer segments include tourists, history enthusiasts, and local residents. Partnerships with regional tourism organizations enhance its ecosystem. The site reflects a small-sized public institution with a clear cultural mission and stable market presence.

Security posture

The current security maturity is basic with HTTPS and cookie consent implemented. The lack of DNSSEC and security headers indicates gaps in defense-in-depth. No visible vulnerabilities or exposed sensitive data were found. Compliance with GDPR is evident through privacy and cookie policies. Incident response readiness is unclear due to missing contact channels for security issues. The security culture appears minimal but functional, with room for formalization and enhancement.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement standard security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Publish a security policy and incident response contact information to improve transparency and readiness.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update them promptly.
  5. Enhance user trust by adding terms of service and data protection officer contact details.

Technical notes

Notes

The website is built on the ikiss CMS platform with jQuery and related plugins for UI and accessibility. It uses slicknav for responsive navigation and flexslider for image sliders. Google Translate integration supports multilingual access. The site is mobile optimized and includes accessibility features such as skip links and ARIA labels. Performance is moderate, with potential improvements in caching and script optimization. The absence of DNSSEC and security headers represents technical debt. Hosting details are limited but registrar information is clear and consistent.
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.
