Security score

65/100

Risk levelMedium

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

The website www.nus.org.uk is currently inaccessible due to a Cloudflare Turnstile CAPTCHA security challenge, which blocks automated access and prevents retrieval of meaningful content or metadata. The WHOIS lookup for the domain failed with an error indicating the domain name contains too many parts and cannot be registered, suggesting the queried domain is invalid or a subdomain rather than a registered domain. Consequently, no registrar, creation, expiry, or registrant information is available. The lack of accessible content and WHOIS data severely limits the ability to analyze the business, technical infrastructure, or security posture in detail. The site is protected by Cloudflare's WAF, indicating a security-conscious hosting environment but also restricting automated analysis.

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

8 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 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';…

  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: Cloudflare

      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

Due to the absence of accessible content, no business intelligence data such as company name, market position, business model, or services can be extracted. The domain queried appears invalid per Nominet WHOIS, which raises questions about the legitimacy or correctness of the domain used for analysis. No contact information, policies, or certifications are present on the accessible page. The website likely belongs to the National Union of Students UK (nus.org.uk), but this cannot be confirmed from the blocked content.

Security posture

The presence of a Cloudflare Turnstile CAPTCHA indicates a strong perimeter security measure to mitigate automated attacks and bots. However, no security headers or SSL configuration details are available from the provided data. The lack of accessible content prevents verification of secure forms, input validation, or vulnerability disclosures. The WHOIS data absence and domain invalidity further reduce trust. Overall, the security posture appears cautious but limits transparency and accessibility.

Recommendations

  1. Consider allowing verified crawlers or providing a public-facing page without WAF challenge to improve accessibility and SEO.
  2. Correct WHOIS queries to use the registered domain (likely nus.org.uk) to obtain accurate domain registration data.
  3. Publish clear privacy, cookie, and terms of service policies accessible without security challenges.
  4. Provide visible contact information and business details on the public website to enhance trust and credibility.
  5. Implement and document security best practices including security headers and vulnerability disclosure policies.

Technical notes

Notes

The website is hosted behind Cloudflare, utilizing their Turnstile CAPTCHA for bot mitigation. The HTML content is minimal and serves only as a challenge page with no business or marketing content. No CMS or frameworks are detectable from the limited HTML. Performance and SEO cannot be assessed due to blocked content. The technical setup prioritizes security over accessibility, which may impact user experience and search engine indexing. Modern JavaScript and CSS are used for the challenge page UI.
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.
