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

The website 'datteln.org' serves as an internal information portal for the city of Datteln, Germany, primarily focused on communicating technical problems and planned solutions to its users. The site is relatively new, established in early 2024, and is operated by the municipal government. The content is minimal but relevant, targeting residents and internal stakeholders of the city administration. The business model is public service oriented, with no commercial aspects evident. The site maintains a moderate level of professionalism with basic branding and navigation clarity. From a technical perspective, the website uses standard web technologies including HTML5, CSS3, and JavaScript, hosted on servers associated with kasserver.com. The site is mobile optimized and provides a smooth user experience, though it lacks advanced frameworks or CMS identification. Performance is moderate, and SEO practices are basic but present. No analytics or advertising technologies are detected, indicating a focus on privacy and simplicity. Security posture is adequate but could be improved. HTTPS is enabled, and the domain status includes clientTransferProhibited, which protects against unauthorized transfers. However, DNSSEC is not enabled, and no security headers were detected, which are recommended to enhance protection. The site lacks a cookie consent mechanism and detailed security or incident response policies. WHOIS data aligns well with the website content, confirming legitimacy and consistent registration details. Overall, the website is safe, with no adult or questionable content. It serves a clear governmental function with minimal tracking or advertising. Recommendations include enabling DNSSEC, adding security headers, implementing cookie consent for GDPR compliance, and publishing security and incident response policies to improve trust and compliance.

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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

  3. GDPR outside view

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

    • 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

    • 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

  4. 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 · found on this site
  • 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

Stadt Datteln operates as a municipal government entity providing public information services. The website targets local residents and internal users, focusing on transparency regarding technical issues. The business model is non-commercial, emphasizing public service and communication. Market positioning is local government with no direct competitors in this niche. The site lacks monetization or partnership indicators. Growth potential is tied to municipal digital transformation initiatives. The partnership ecosystem is limited, with no external business partners identified. Strategic observations suggest a focus on internal communication efficiency and citizen engagement through digital channels.

Security posture

The current security maturity level is basic. HTTPS is enforced, and domain transfer protections are in place. However, the absence of DNSSEC and security headers reduces the overall security posture. No vulnerability disclosure or incident response information is provided, which limits transparency and preparedness. GDPR compliance is partially addressed through privacy policy availability but lacks cookie consent mechanisms. No exposed sensitive data or vulnerable libraries were detected. The security culture appears minimal but aligned with basic governmental standards. Enhancements in security policies and technical controls are recommended to mitigate risks.

Recommendations

  1. Enable DNSSEC to strengthen domain name system security.
  2. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a cookie consent banner to comply fully with GDPR requirements.
  4. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Consider integrating analytics with privacy-respecting configurations to monitor site usage and improve user experience.

Technical notes

Notes

The website is built with standard web technologies without reliance on heavy frameworks or CMS platforms, indicating a lightweight and maintainable infrastructure. Hosting is provided by kasserver.com, a known hosting provider. The site is mobile optimized and uses responsive design principles. Performance is moderate with no evident optimization issues. However, the lack of advanced SEO and accessibility features suggests room for improvement. No third-party analytics or advertising scripts reduce complexity and privacy risks. Technical debt appears low, but modernization opportunities include adding security headers and enhancing GDPR compliance mechanisms.
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.
