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

The website www.rostock.de serves as the official city portal for the Hanseatic and University City of Rostock, Germany. It provides comprehensive information on tourism, lifestyle, culture, activities, historical and maritime topics, targeting residents and visitors alike. The portal is positioned as a government entity's digital presence, offering key city-related services and information. Technically, the site is built on the Contao Open Source CMS platform, employs modern web technologies including lazy loading and cookie consent via Cookiebot, and integrates Google Tag Manager for analytics. The site demonstrates good mobile optimization and SEO practices, although accessibility features are basic. Security posture is adequate with HTTPS enabled and cookie consent mechanisms in place; however, the absence of explicit security headers and a published security policy limits its security maturity. Privacy compliance is partial, with cookie consent present but no visible privacy policy or terms of service pages. WHOIS data indicates hosting within academic and government infrastructure, consistent with the city’s profile, though registrant details are minimal. Overall, the site is trustworthy and professional but would benefit from enhanced transparency in privacy and security policies.

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

2 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 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
  2. 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

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

Rostock.de operates as a government portal providing essential city information and services, focusing on tourism, culture, and lifestyle. Its market position is that of an official municipal website serving both local citizens and tourists. The business model is informational and service-oriented, with no direct commercial transactions evident. The portal leverages partnerships with academic institutions as indicated by its DNS infrastructure. Growth indicators include multilingual support and integration of modern web technologies. The site’s ecosystem includes external services like Cookiebot and Google Tag Manager for compliance and analytics. Strategic observations suggest opportunities to improve user trust and engagement by publishing comprehensive privacy and security policies and enhancing contact transparency.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is enforced, and cookie consent mechanisms are implemented, indicating awareness of privacy regulations. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is provided, limiting transparency and readiness for security incidents. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The site would benefit from adopting security best practices including publishing a security policy, implementing security headers, and providing clear incident response contacts to enhance its security culture and compliance posture.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages to improve privacy compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen security posture.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and incident response.
  4. Provide clear and accessible contact information including security incident contacts to enhance transparency and readiness.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built on the Contao Open Source CMS platform, leveraging modern front-end technologies such as lazy loading (lazysizes) and SVG icons for performance and visual quality. Google Tag Manager is used for analytics, and Cookiebot manages cookie consent, indicating compliance efforts. The site is mobile optimized with responsive design and preloading of fonts and scripts for performance. However, no explicit hosting provider information was found. Performance is moderate with room for improvement in loading speed and accessibility. The technical stack is modern but could benefit from enhanced security configurations and improved metadata completeness for SEO and accessibility.
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.
