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

6 findings 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.

    • 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  4. 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"

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, providing essential services to a medium-sized community. Its market position is strong locally, supported by partnerships with payment processors, communication platforms, and governance tools. The business model is focused on delivering quality education and student support, with revenue likely derived from public funding and associated educational grants. The website's integration with external trusted services indicates a mature partnership ecosystem. Growth indicators include active news updates and event management. The school maintains a clear focus on community engagement and educational excellence.

Security posture

The website demonstrates a baseline security maturity with HTTPS and secure form handling. However, the absence of key security headers such as Content-Security-Policy and HSTS reduces its defense against common web attacks like XSS and clickjacking. No vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Analytics and Elfsight widgets introduces potential risk vectors that should be regularly reviewed. The lack of an incident response contact or vulnerability disclosure policy suggests limited formal security governance. Overall, the security posture is moderate but could benefit from implementing best practices and formal policies.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and HSTS to enhance web security.
  2. Add a cookie consent banner/mechanism to comply fully with privacy regulations and improve user transparency.
  3. Correct WHOIS queries to use the base domain (tarporleyhigh.co.uk) to obtain accurate domain registration data.
  4. Establish and publish an incident response or vulnerability disclosure policy to improve security governance and trust.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities and update them accordingly.

Technical notes

Notes

The website is built on ASP.NET WebForms technology, utilizing jQuery, Bootstrap 3.3.1, bxSlider, and Slick Slider for UI components and interactivity. Google Tag Manager and Google Analytics are used for tracking user behavior. The site is moderately optimized for mobile devices and has a clear navigation structure. Performance is average, with some potential for improvement by optimizing images and scripts. The absence of modern frontend frameworks or CMS indicates a traditional web architecture. Technical debt may exist due to older Bootstrap version and ASP.NET WebForms usage. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports the business needs but could be modernized for better performance and maintainability.
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.
