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

Denstone College is a coeducational boarding and day school serving students aged 4 to 18, located in the United Kingdom. The institution offers a broad range of educational services including Pre-Prep, Prep, Senior, and Sixth Form education, complemented by co-curricular activities and boarding facilities. The website reflects a well-structured educational institution with clear navigation and professional content aimed at parents, students, and staff. The school positions itself as an accessible and comprehensive educational provider in the Staffordshire and Derbyshire region. Technically, the website employs a modern technology stack including jQuery, Bootstrap, Kendo UI, and Slick Carousel, hosted on a CMS platform named Amais. It integrates Google Tag Manager and CookieYes for analytics and privacy compliance, respectively. The site demonstrates good mobile optimization and SEO practices, although accessibility features are basic. Performance is moderate, with room for optimization. From a security perspective, the site enforces HTTPS and uses anti-forgery cookies, alongside a robust cookie consent mechanism that complies with GDPR standards. However, explicit security headers are not detected, and there is no publicly available incident response or vulnerability disclosure information. The WHOIS data is privacy protected or unavailable, which is typical for educational institutions and does not raise immediate concerns. Overall, Denstone College's website presents a professional and trustworthy online presence with good privacy compliance and moderate technical maturity. Strategic improvements in security headers, incident response transparency, and contact information visibility could further enhance trust and security posture.

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. 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. 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 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

Denstone College operates in the education sector as an independent school offering day and boarding options. Its market positioning is that of a reputable regional educational institution with a comprehensive curriculum and co-curricular activities. The business model focuses on tuition and boarding fees, supplemented by venue hire and ancillary services. The target customer segments include families seeking quality education in Staffordshire and surrounding areas. The website indicates a medium-sized institution with consistent branding and a clear partnership ecosystem, although no explicit partners or subsidiaries are listed. Growth indicators include active content updates and engagement tools such as admissions calculators and enquiry forms. The school leverages digital marketing tools and analytics to optimize outreach and user experience.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS and a comprehensive cookie consent framework aligned with GDPR. Anti-forgery cookies indicate protection against CSRF attacks. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of publicly available incident response contacts or vulnerability disclosure policies limits transparency and readiness communication. Overall, the security maturity is good but could be enhanced by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a clear incident response policy and provide dedicated security contact channels (e.g., security@ or abuse@ email addresses) to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to minimize risks from vulnerable dependencies.
  4. Enhance accessibility features to meet WCAG standards, improving inclusivity and compliance.
  5. Increase visibility of official contact information such as phone numbers and emails to improve business credibility and user trust.

The site is mobile optimized with responsive design and includes multimedia content such as images and videos.

Overall, the infrastructure supports a professional educational website with scope for modernization and security hardening.
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.
