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

Teach Cambridge is a specialized educational platform providing OCR teachers with access to a wide range of teaching resources, including assignments, examiner reports, exemplars, past papers, and training materials. The platform is positioned as a secure, personalized website under the reputable Cambridge University Press & Assessment brand, targeting educators involved in OCR qualifications. The business model focuses on supporting teachers with high-quality, official resources to enhance learner assessment preparation. Technically, the website is built using modern React technology, hosted with Cloudflare DNS services, and integrates analytics tools such as Google Tag Manager and Hotjar for user behavior insights. The site demonstrates good mobile optimization and a professional design, although accessibility and SEO optimizations are basic. Security-wise, the site enforces HTTPS and uses clientTransferProhibited domain status, but lacks DNSSEC and advanced security headers. No explicit security or incident response policies are published, indicating room for improvement in transparency and compliance. Overall, the website is trustworthy, safe, and well-aligned with its educational mission, but could benefit from enhanced security practices and clearer contact channels.

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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      What to do: Document all third-party data sharing in your privacy policy

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

Teach Cambridge operates in the education sector, specifically supporting OCR teachers with official resources. Its market position is that of a niche, authoritative platform backed by Cambridge University Press & Assessment, lending strong brand credibility. The business model is service-oriented, providing digital access to teaching materials rather than direct sales. Target customers are educators preparing learners for assessments. The platform leverages partnerships with Cambridge University Press & Assessment and integrates modern web technologies to deliver content efficiently. Growth indicators include a relatively recent domain launch in 2021 and ongoing content updates. The ecosystem includes analytics and user tracking tools to optimize user engagement. Strategic observations suggest focusing on expanding contact and support options and enhancing security compliance to strengthen market trust.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and domain transfer protections in place. However, the absence of DNSSEC and security headers such as CSP, HSTS, and X-Frame-Options limits its defense-in-depth posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published incident response or security policies reduces transparency and preparedness perception. Data protection practices appear basic, with privacy and cookie policies present but no explicit consent mechanisms. The integration of Hotjar and Google Tag Manager indicates moderate user tracking, which should be balanced with privacy compliance. Overall, the security posture is adequate for an educational platform but requires enhancements to meet higher compliance and resilience standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Publish explicit security policy and incident response pages to increase transparency and user trust.
  4. Introduce cookie consent mechanisms to comply fully with GDPR and enhance privacy compliance.
  5. Expand contact options with verified company emails and phone numbers for support and incident reporting.

Technical notes

Notes

The website is built on a modern React framework with client-side rendering, supported by Cloudflare DNS and CDN services. It uses Google Tag Manager and Hotjar for analytics and user behavior tracking. The site loads a main JavaScript bundle and CSS stylesheets efficiently, with moderate performance observed. Mobile optimization is good, ensuring usability across devices. Accessibility features are basic but present. SEO optimization is minimal, relying on meta description and title tags without advanced structured data or Open Graph tags. The absence of CMS suggests a custom-built solution tailored for the educational content delivery. Technical risks include lack of DNSSEC and missing security headers, which could expose the site to DNS attacks and clickjacking. Modernization opportunities include enhancing SEO, accessibility, and security configurations to improve overall resilience and discoverability.
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.
