Risk levelHigh

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

Amadeus International School Vienna is a well-established private international school offering IB education and boarding services with a unique integrated Music and Arts Academy. The school targets international students and families seeking high-quality education in Vienna. The website is professionally designed with rich content and multimedia, reflecting a mature digital presence. Technically, the site is built on WordPress with modern plugins and frameworks, but suffers from a critical lack of HTTPS due to an invalid SSL certificate, which significantly impacts its security posture. Privacy and cookie policies are implemented with consent mechanisms, supporting GDPR compliance. Contact information is clearly presented, enhancing business credibility. Overall, the site is trustworthy and professional but requires urgent security improvements to protect user data and enhance trust.

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

8 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

The school holds a strong market position as the only international boarding school in Vienna with IB accreditation and specialized arts programs. It leverages partnerships with recognized organizations such as the IB, HMC, BSA, and COIS, and piano manufacturers like Bösendorfer and Steinway, enhancing its prestige. The business model focuses on premium education services with boarding and extracurricular offerings. The website supports admissions and engagement through integrated application services and social media channels. Growth indicators include active scholarship programs and a vibrant community presence. The partnership ecosystem is robust, supporting both academic and extracurricular excellence.

Security posture

The current security posture is weak due to the absence of a valid SSL certificate and lack of HTTPS, exposing users to potential data interception risks. While no critical vulnerabilities like Heartbleed or POODLE are detected, the missing HTTPS and HSTS headers are significant gaps. The site uses reCAPTCHA on forms and cookie consent mechanisms, indicating some security awareness. However, the lack of advanced security headers and session management features reduces overall security maturity. Incident response and security policy information are not found, suggesting limited transparency in security governance.

Recommendations

  1. Obtain and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Enhance session management with session resumption and secure cookies.
  5. Publish a clear security policy and incident response contact information to improve transparency and trust.
Technical notes

Notes

The website is built on a modern WordPress platform with a comprehensive tech stack including Yoast SEO, Borlabs Cookie for consent management, LayerSlider for multimedia, and Google Tag Manager for analytics. The site uses jQuery and MediaElement.js for media playback. Performance is moderate to slow, possibly due to large images and multiple scripts. Mobile optimization is good with responsive design and Google Fonts integration. SEO is well implemented with meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but present. Hosting details are inferred from DNS but not explicitly stated. Technical debt is low, but the lack of HTTPS is a critical risk that overshadows other technical strengths.
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.
