Partial score · DNS & email only

56/100

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

The American International School Vienna (AIS Vienna) is a well-established international educational institution located in Vienna, Austria. The website presents a comprehensive overview of the school's offerings, including early childhood through high school education, student life, admissions, and community engagement. The school holds multiple international accreditations, reinforcing its credibility and commitment to quality education. The website is professionally designed using the Squarespace platform, featuring clear navigation, active social media integration, and basic privacy compliance mechanisms such as a cookie consent banner. Technically, the site leverages modern web technologies including jQuery, Google Fonts, and Google Analytics for tracking. However, a critical security shortfall is the absence of a valid SSL certificate, resulting in no HTTPS encryption and disabled modern TLS protocols. This significantly impacts the site's security posture and user trust. Security headers are partially implemented but could be enhanced. Privacy compliance is basic, with a privacy policy present but lacking explicit GDPR compliance indicators. Overall, the site is functional and informative but requires urgent security improvements to protect user data and enhance trust. Strategic recommendations include installing a valid SSL certificate, enabling HSTS, and improving security policies and incident response readiness.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

AIS Vienna operates in the education sector, targeting families seeking international schooling in Austria. Its business model focuses on providing comprehensive educational services from early childhood to high school, supported by a strong community and alumni network. The school benefits from multiple accreditations, which serve as trust signals and competitive advantages. The website's content and social media presence indicate active engagement and a commitment to transparency. Revenue streams likely include tuition fees and donations, with a dedicated giving section. The partnership ecosystem includes recognized accreditation bodies such as MSA-SF, IB, and CIS. Growth indicators include recent news and events updates, reflecting an active and evolving institution.

Security posture

The current security posture of the website is weak due to the lack of a valid SSL certificate, which is a critical vulnerability exposing users to potential data interception and man-in-the-middle attacks. The absence of HTTPS also disables modern TLS protocols, further weakening encryption. While some security headers like X-Content-Type-Options and X-Frame-Options are present, the lack of HSTS and OCSP stapling reduces protection against protocol downgrade and certificate revocation issues. No explicit incident response or vulnerability disclosure policies are found, indicating limited preparedness for security incidents. Privacy compliance is basic, with cookie consent implemented but no clear GDPR adherence. Overall, the site requires immediate remediation to meet standard security best practices.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  3. Activate modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  4. Enhance security headers configuration to include Content-Security-Policy and Referrer-Policy.
  5. Develop and publish clear security policies including incident response and vulnerability disclosure.
  6. Improve privacy compliance by explicitly addressing GDPR requirements and data retention policies.
  7. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  8. Optimize website performance and accessibility to improve user experience and SEO.

Notes

The website is built on the Squarespace platform, utilizing standard web technologies such as HTML5, CSS3, and JavaScript libraries including jQuery. It integrates Google Fonts for typography and Google Analytics via Google Tag Manager for visitor tracking. The site is hosted on Squarespace servers, as indicated by HTTP headers and DNS records. Performance metrics are not available, but the site appears to be mobile optimized with responsive design elements. Accessibility features are basic, with skip links and semantic HTML elements present. SEO is supported by canonical tags, Open Graph metadata, and structured JSON-LD data describing the organization and local business. Technical risks include the lack of SSL and disabled TLS protocols, which could impact search rankings and user trust.
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.
