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.

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

HHN holds a strong market position as a leading applied sciences university in Germany, targeting students, researchers, and industry partners. Its business model revolves around education, research, and international exchange programs, supported by partnerships with over 220 partner universities. The institution leverages its reputation for practical and interdisciplinary study programs to attract students and foster innovation. The presence of career support programs and events indicates a focus on employability and community engagement. The university's digital ecosystem includes multiple social media platforms and podcast channels, enhancing outreach and brand visibility. The lack of direct contact emails or phone numbers on the website suggests a preference for controlled communication via contact forms, aligning with privacy and security best practices.

Security posture

The website exhibits a solid security posture with enforced HTTPS, cookie consent, and sandboxed iframes for login sessions. However, it lacks explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which could enhance protection against common web attacks. No security or incident response policies are publicly disclosed, and no vulnerability disclosure or security.txt files are present, indicating room for improvement in transparency and incident readiness. The use of third-party scripts like Google Tag Manager is noted, but no vulnerable libraries or exposed sensitive data were found. Overall, the security maturity is good but could be elevated by adopting additional best practices and publishing security documentation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance form security by ensuring CSRF protection and input validation on all user input points.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

The technical stack is modern and well-maintained, supporting a professional and user-friendly digital presence.
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.
