Risk levelHigh

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

The website www.petersberg-erfurt.de serves as the official digital presence for the Zitadelle Petersberg, a historic baroque fortress and cultural landmark in Erfurt, Germany. It provides comprehensive visitor information, including guided tours, exhibitions, events, gastronomy, and family-friendly activities, targeting tourists and local visitors interested in cultural heritage. The site is well-branded and professionally designed, leveraging TYPO3 CMS and hosted on AWS infrastructure, ensuring reliable performance and modern technical standards. Social media integration enhances visitor engagement and outreach. However, the site lacks explicit privacy and terms of service pages, which are important for compliance and user trust. Contact information such as emails and phone numbers are not explicitly visible, which could hinder direct communication. Security posture is generally good with HTTPS and cookie consent implemented, but the absence of security headers and incident response contacts are areas for improvement. Overall, the website is a trustworthy and valuable resource for cultural tourism but would benefit from enhanced privacy compliance and security best practices.

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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

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 Zitadelle Petersberg website positions itself as a key cultural tourism hub in Erfurt, offering a variety of services including visitor centers, guided tours, exhibitions, and gastronomy. Its partnership with Erfurt Tourismus GmbH indicates a collaborative ecosystem supporting regional tourism. The business model focuses on cultural heritage promotion and visitor experience enhancement, with revenue likely derived from tours, events, and souvenir sales. The target audience includes families, tourists, and educational groups, reflecting a community-oriented approach. The use of a reputable CMS and AWS hosting suggests investment in digital infrastructure. Growth opportunities may include expanding digital offerings such as the Petersberg-App and increasing online engagement. The absence of detailed business registration or VAT information limits deeper corporate insights.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism in place, indicating awareness of basic security and privacy requirements. However, the lack of security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of explicit incident response contacts or security policies suggests limited readiness for handling security incidents. Compliance gaps include missing privacy and terms of service pages, which are critical under GDPR and other regulations. Recommendations include implementing security headers, publishing privacy and security policies, and providing clear contact channels for security issues to enhance trust and compliance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages to improve GDPR compliance and user trust.
  2. Implement standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security posture.
  3. Add clear contact information including emails and phone numbers for general and security-related inquiries.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance cookie consent transparency with detailed information on data usage and retention.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used open-source content management system, combined with Bootstrap for responsive design and UI components. Hosting is provided via Amazon AWS DNS services, indicating a reliable and scalable infrastructure. The site features multimedia content including videos and image carousels, enhancing user engagement. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and Open Graph data. However, there is room for improvement in accessibility compliance and performance optimization. The technical stack is modern but could benefit from enhanced security configurations and more visible privacy controls.
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.
