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. 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 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
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

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 City of Bremen leverages this website as a key communication and service platform, enhancing its market position as a government authority. The business model is informational and service-oriented, focusing on public engagement and tourism promotion. The site integrates with partner domains related to Bremen's tourism and government services, forming a cohesive digital ecosystem. The use of analytics and marketing tools like Matomo and Facebook Pixel indicates a moderate level of user behavior tracking to optimize content and outreach. The absence of explicit contact details and security disclosure suggests areas for improvement in transparency and user trust. The website's content quality and navigation support effective user engagement, reinforcing the city's digital presence.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and multiple security headers likely in place. Cookie consent mechanisms are comprehensive, supporting GDPR compliance and user privacy. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the lack of a published security policy, incident response information, or vulnerability disclosure program limits transparency and may hinder rapid response to security incidents. The site uses CSRF tokens and secure cookies, indicating good security hygiene. Recommendations include publishing explicit security policies and establishing clear channels for security incident reporting to enhance trust and readiness.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear contact information for security and privacy inquiries, including incident response contacts.
  4. Regularly review and update cookie and privacy policies to maintain GDPR compliance.
  5. Enhance transparency by including business contact details and certifications where applicable.

Technical notes

Notes

The website is built using modern front-end technologies, notably Vue.js, and integrates analytics platforms such as Matomo and Google Analytics. Cookiebot is used for cookie consent management, ensuring compliance with privacy regulations. The site is mobile-optimized with good accessibility features and SEO practices. Performance is moderate, with asynchronous loading of scripts and use of CDN-hosted resources. Hosting details are not explicitly identified, but Cloudflare services are implied through cookies and scripts. The technical infrastructure supports a secure and user-friendly experience, though opportunities exist to improve transparency and documentation of security and privacy practices.
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.
