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

4 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 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"

  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
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 operates in the education sector, targeting families seeking high-quality boys' day schooling in North West London. Its business model is based on independent tuition fees, scholarships, and community engagement. The website highlights key services such as admissions, academic programs, co-curricular activities, and alumni relations, supported by a strong brand identity and consistent messaging. The presence of related domains for prep school, alumni, sports, and calendar services indicates a well-structured ecosystem. The school leverages digital marketing and analytics tools to maintain engagement and optimize outreach. Growth indicators include recent content updates and active social media channels. Strategic partnerships with related domains enhance service delivery and community involvement.

Security posture

The website maintains a good security posture with HTTPS enabled and use of reputable third-party scripts for analytics and consent management. Cookie consent is granular and compliant with GDPR standards. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not explicitly found and should be verified or implemented to enhance protection against common web attacks. There is no visible incident response or security policy information, which could be improved to demonstrate security maturity. Overall, the site is secure for its purpose but could benefit from additional security hardening and transparency.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response plan accessible to users and stakeholders.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance transparency by providing data retention policies and DPO contact information.
  5. Monitor WHOIS and domain registration status to resolve inconsistencies and ensure domain legitimacy.

Notes

The website is built on WordPress CMS with Yoast SEO plugin for search optimization. It uses Google Tag Manager to manage analytics and marketing tags, integrating Google Analytics, Matomo, and Microsoft Clarity for user behavior tracking. CookieYes manages cookie consent with a detailed preference center. The site is mobile responsive with good accessibility features and fast loading multimedia content. The technical stack is modern and well-maintained, though hosting provider details are not explicit. Performance is moderate with room for optimization. The site architecture supports clear navigation and user engagement, with structured data enhancing search engine understanding. Technical risks are minimal but include potential improvements in security headers and domain registration transparency.
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.
