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

The website frankfurt.de serves as the official city portal for Frankfurt am Main, providing comprehensive information and services related to municipal administration, citizen services, cultural events, and city politics. It targets residents, visitors, and businesses in Frankfurt, offering multilingual support and extensive navigation to various city departments and services. The portal positions itself as a trusted government resource with a large-scale digital presence and active social media engagement. Technically, the site employs modern web technologies including Bootstrap utilities, FontAwesome icons, media players, and translation scripts, ensuring good mobile optimization and accessibility. The site loads with moderate performance and includes SEO-friendly metadata and Open Graph tags, enhancing discoverability and social sharing. From a security perspective, the site enforces HTTPS and uses secure libraries, but lacks visible security headers and published security or incident response policies. No vulnerability disclosure or security.txt files were found. Privacy and cookie policies are not evident, which is a compliance gap. Contact information such as emails and phone numbers are not explicitly presented, limiting direct communication channels. Overall, the site is a professional and trustworthy government portal with good content quality and technical implementation. However, it would benefit from enhanced privacy compliance, explicit security policies, and clearer contact information to improve user trust and regulatory adherence.

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

6 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

    • 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

  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"

  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

Frankfurt.de operates as an essential government entity website, representing the city administration of Frankfurt am Main. Its business model focuses on providing public services, information dissemination, and citizen engagement through digital channels. The portal supports a broad target audience including residents, businesses, tourists, and civic participants. The site leverages partnerships with related city platforms such as ffm.de and geoportal.frankfurt.de to extend service offerings. The extensive social media presence across multiple platforms indicates a strategic approach to community outreach and transparency. The portal's market position is strong as the official digital gateway to city services, with a consistent brand and high trust indicators. Revenue streams are not applicable as it is a public service platform. Growth indicators include ongoing digital initiatives like Smart City newsletters and citizen participation platforms.

Security posture

The security posture of frankfurt.de is moderate. The site uses HTTPS, ensuring encrypted communication, and employs reputable JavaScript libraries and frameworks. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No visible incident response or security contact information is provided, which may hinder timely reporting and mitigation of security incidents. The lack of a vulnerability disclosure policy or security.txt file limits transparency and community engagement in security matters. No exposed sensitive data or vulnerable libraries were detected in the provided content. Overall, while basic security measures are in place, enhancements in security policy publication and header implementation are recommended to elevate the security maturity level.

Recommendations

  1. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and implement a consent mechanism for cookies.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen protection against web vulnerabilities.
  3. Provide explicit security and incident response policies including contact channels like security@ or abuse@ email addresses.
  4. Introduce a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance visibility of official contact information including emails and phone numbers to improve user trust and communication.

Technical notes

Notes

The website is built using a combination of modern front-end technologies including Bootstrap utilities for responsive design, FontAwesome for icons, RoyalSlider for content sliders, and MediaElement.js for video playback. The presence of HLS.js indicates support for streaming media. The site uses a custom translation script (Conword) for multilingual support, enhancing accessibility for diverse users. The HTML structure is well-organized with semantic elements and ARIA roles, supporting accessibility standards. Performance is moderate, with some large images and multiple scripts that could be optimized further. No CMS is explicitly detected from the source. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports a robust and user-friendly experience but could benefit from performance optimizations and enhanced security configurations.
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.
