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

Perryfields Junior School is a UK-based educational institution providing junior school education with a focus on academic excellence, social and emotional development, and community engagement. The website serves as a comprehensive portal for parents, students, and staff, offering detailed curriculum information, news, events, and contact details. The school holds multiple accreditations including an Ofsted Outstanding rating, reinforcing its strong market position within the local education sector. Technically, the website employs a modern tech stack including jQuery, Lightbox, Font Awesome, and Google Translate, hosted on the School Spider CMS platform. The site is mobile-optimized with good SEO and accessibility features, although some improvements in accessibility and cookie consent mechanisms are recommended. Performance is moderate with a clean, professional design and clear navigation. From a security perspective, the site uses HTTPS with no exposed sensitive data and employs secure external libraries. However, it lacks important security headers and does not provide vulnerability disclosure or incident response information. Privacy compliance is adequate with clear privacy and cookie policies, but the absence of a cookie consent mechanism is a gap. Overall, the website is trustworthy, professional, and well-suited for its audience. Strategic recommendations include enhancing security headers, implementing cookie consent, and adding incident response details to improve compliance 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

4 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  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 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';…

  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. 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

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

Business profile

Perryfields Junior School operates as a non-profit educational institution serving the Chelmsford community in the UK. Its market positioning is strong locally, supported by an Ofsted Outstanding rating and multiple accreditations. The school’s business model focuses on delivering quality education and engaging parents through digital communication channels. Revenue streams are typical of public education institutions, likely funded by local government and educational grants. The target customer segment includes parents of junior school children and local stakeholders. The partnership ecosystem includes the Essex County Council and School Spider CMS provider. Growth indicators include active content updates, event management, and community engagement through blogs and news. The school maintains a professional online presence with consistent branding and trust signals.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Use of reputable external libraries and content delivery networks reduces risk. However, the absence of key security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options represents a moderate risk that could be mitigated. Lack of a vulnerability disclosure policy or security.txt file limits transparency and incident response readiness. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are missing, which could lead to compliance issues. Overall, the security maturity is good but can be improved with additional controls and transparency.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and ePrivacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to improve transparency and facilitate responsible reporting of security issues.
  4. Include incident response contact information to demonstrate readiness and improve trust.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on the School Spider CMS platform, utilizing a combination of jQuery, Lightbox, Font Awesome, and Slick Slider for interactive and visual elements. Google Translate integration supports multilingual accessibility. The site is responsive and optimized for mobile devices with a clean, modern design. Performance is moderate, with potential improvements in loading speed through optimization of images and scripts. SEO is supported by proper meta tags and structured data (JSON-LD). Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. No hosting provider details were identified from the content. Overall, the technical infrastructure is solid but could benefit from modernization and enhanced security configurations.
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.
