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

The website 'Warn- und Informationsdienst' operated by CERT-Bund serves as an official German federal government portal providing daily IT security warnings, vulnerability information, and patch advisories. It targets IT security officers within the federal administration, as well as other organizations and interested citizens. The site is positioned as a trusted source for cybersecurity information within the government sector, offering critical updates to help mitigate security risks. Technically, the site is built using Angular 18.2.9, with modern web technologies ensuring moderate performance and good mobile optimization. The absence of blocking mechanisms or WAF challenges indicates full accessibility. However, some security best practices such as explicit security headers and a formal incident response contact are not visible, suggesting room for improvement. Security posture is strong with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. Privacy compliance is adequate with a privacy policy and cookie dialog present, though the cookie consent mechanism could be enhanced. Business credibility is high due to the official government affiliation and consistent branding. Overall, the website is a reliable and professional government resource with a solid technical foundation and trustworthy content. Strategic improvements in security headers, incident response transparency, and cookie consent would further strengthen its security and compliance profile.

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

5 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 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

CERT-Bund operates as a government entity providing cybersecurity advisories and vulnerability information primarily to the German federal administration. Its market position is that of an authoritative source for IT security within government, with no commercial business model. The service is publicly accessible and supports a broad audience including other organizations and citizens. The website reflects a focused mission with no advertising or tracking, emphasizing trust and reliability. The partnership ecosystem is limited to government infrastructure domains. Growth indicators are not applicable given the public service nature. The site’s operations are consistent with government standards and expectations.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and no detected vulnerabilities or exposed sensitive data. However, the lack of explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces defense-in-depth. No incident response contact or security policy is published, which could hinder rapid vulnerability reporting and response. GDPR compliance is indicated by the presence of a privacy policy and cookie dialog, but the cookie consent mechanism is not explicit. Overall, the security culture appears professional but could benefit from enhanced transparency and formalized security documentation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to improve defense-in-depth.
  2. Publish clear incident response contact information and a formal security policy to facilitate vulnerability reporting and transparency.
  3. Enhance the cookie consent mechanism to comply with explicit opt-in requirements under GDPR.
  4. Consider adding a security.txt file to standardize vulnerability disclosure processes.
  5. Regularly review and update privacy and security documentation to maintain compliance and trust.

Technical notes

Notes

The website uses Angular 18.2.9 as its frontend framework, indicating a modern single-page application architecture. CSS and JavaScript are used for styling and interactivity. The site loads with moderate performance and good mobile responsiveness. No CMS or hosting provider details are explicitly detected. The absence of analytics or tracking scripts suggests a privacy-focused implementation. Technical debt appears low, but the lack of security headers and formal security documentation represents an area for modernization. Overall, the technical infrastructure supports the business mission effectively with opportunities for security enhancements.
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.
