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

2 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

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

HvA holds a strong market position as a large educational institution in Amsterdam, serving a diverse student body and engaging in applied research. Its business model revolves around providing accredited higher education and research services, supported by collaborations with industry and community partners. The website content and structure indicate a focus on student recruitment, research dissemination, and community engagement. The presence of multiple language options and extensive program information supports broad accessibility. Partnerships with related domains like amsterdamuas.com enhance its ecosystem. The institution's transparency in privacy and cookie policies, along with active social media presence, supports its credibility and outreach efforts.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS, comprehensive security headers, and a cookie consent mechanism compliant with GDPR. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency in security governance. The use of third-party scripts like Google Tag Manager and Cookiebot is standard but requires ongoing monitoring for vulnerabilities. Overall, the security posture is good but could be enhanced by publishing explicit security policies and providing dedicated security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website to improve transparency and trust.
  2. Implement a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  3. Provide explicit security contact channels such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance user awareness and trust by including certifications or compliance badges related to security and privacy.

Technical notes

Notes

The website is built using modern web technologies, primarily Next.js (React framework), supported by Hippo CMS (Bloomreach) for content management. It integrates Google Tag Manager for analytics and Cookiebot for cookie consent management, reflecting a mature digital infrastructure. The site is mobile-optimized and accessible, with good SEO practices including meta tags and Open Graph data. Performance is moderate, likely influenced by rich media content and third-party scripts. The technical stack is well-suited for a large educational institution, though continuous performance monitoring and optimization could further enhance user experience. No significant technical debt or risks were identified from the HTML content.
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.
