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.

Business context

Business profile

Universität Hamburg holds a strong market position as a leading German university with a broad academic portfolio and significant research output. Its business model is public education and research, funded primarily by government and public sources. The university targets a diverse audience including prospective and current students, academic staff, researchers, and alumni. It maintains a broad partnership ecosystem with academic clusters, research centers, and community organizations. The website content and certifications indicate a commitment to quality, diversity, and sustainability. Growth indicators include active event programming, research collaborations, and digital engagement via social media. The university's operations are supported by a robust digital presence, leveraging analytics and error tracking to optimize user experience. The lack of direct contact emails suggests a controlled communication approach, likely to manage inquiries efficiently. The institution's transparency in audits and accreditations enhances its credibility and trustworthiness in the education sector.

Security posture

The security posture of the Universität Hamburg website is moderate to good. HTTPS is enforced, and CSRF tokens are implemented, which are positive indicators. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. There is no public incident response or vulnerability disclosure policy, which could hinder timely reporting and mitigation of security issues. The use of third-party analytics and tracking services is evident, but privacy compliance could be improved by implementing explicit cookie consent mechanisms. No vulnerabilities or exposed sensitive data were detected in the HTML content. The website demonstrates a security-aware culture through error tracking and anonymized data collection. To enhance security maturity, the university should consider publishing a security policy, incident response contacts, and adopting security headers to protect against common web attacks.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance web security.
  2. Deploy a visible cookie consent mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish a clear vulnerability disclosure policy and security.txt file to facilitate responsible security reporting.
  4. Provide explicit contact information for incident response and security concerns to improve trust and responsiveness.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website is built on a modern technology stack with HTML5, CSS3, and JavaScript, including libraries such as jQuery and Swiper.js for interactive elements. It uses WOFF2 web fonts loaded with CORS enabled for performance and security. Analytics are handled by eTracker, and error monitoring is done via BetterWeb, indicating a proactive approach to performance and reliability. The CMS appears to be custom or university-specific, with no common commercial CMS detected. Hosting is likely managed by the German Research Network (DFN) or university infrastructure, supported by the DNS server dns-3.dfn.de. The site is mobile-optimized and accessible, with responsive design adapting to different screen sizes. Performance is moderate, with preloading of fonts and scripts to improve load times. SEO is well addressed with meta tags, Open Graph tags, and structured navigation. Opportunities exist to improve technical security and privacy compliance, but overall the infrastructure supports a robust and user-friendly academic website.
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.
