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

Castle Computers is a small, client-focused IT and telecommunications service provider based in the United Kingdom. The company emphasizes personalized service and long-term client relationships, positioning itself as the IT department for businesses. Their key offerings include IT services, cloud services, cybersecurity, telecommunications, and Sage software solutions. The website is professionally designed using Squarespace, with good mobile optimization and clear navigation. However, the absence of privacy and cookie policies, as well as missing WHOIS domain registration data, present concerns regarding compliance and legitimacy. Security posture is generally good with HTTPS and HSTS enabled, but additional security headers and policies are recommended. Overall, the business appears legitimate but would benefit from enhanced transparency and compliance documentation.

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. 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: Facebook, LinkedIn, Google APIs

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

Castle Computers operates in the technology and telecommunications sectors, targeting businesses that require managed IT and telecom solutions. Their business model focuses on providing tailored services with a personal touch, differentiating from large corporate IT firms. The company maintains active social media profiles on Instagram, Facebook, and LinkedIn, supporting brand presence and customer engagement. The lack of detailed company registration or VAT information on the website limits deeper business intelligence insights. The partnership with ISL Online for remote support indicates integration with third-party service providers. Growth potential exists through expanding compliance and security transparency.

Security posture

The website enforces HTTPS with HSTS, indicating a secure transport layer. However, no additional security headers such as Content-Security-Policy or X-Frame-Options were detected, which could improve protection against common web attacks. The absence of privacy and cookie policies suggests potential compliance gaps with GDPR and other data protection regulations. No incident response or vulnerability disclosure information is provided, limiting transparency in security management. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is moderate but could be significantly improved with enhanced policies and headers.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance web security.
  3. Provide clear contact information including company emails and phone numbers to improve business credibility.
  4. Consider publishing a vulnerability disclosure policy and security.txt file to foster transparency and trust.
  5. Verify and publish domain registration details to resolve WHOIS data inconsistencies and improve legitimacy.

Technical notes

Notes

The website is built on the Squarespace platform, utilizing modern web technologies including HTML5, CSS3, and JavaScript. The use of the Roboto font family and responsive design techniques ensures good mobile optimization and user experience. Performance is moderate, typical for a Squarespace-hosted site. SEO optimization is basic with proper meta tags and Open Graph data present. Accessibility features are minimal and could be enhanced. No third-party analytics or advertising scripts were detected, indicating minimal tracking. The technical infrastructure is stable but could benefit from improved accessibility and security enhancements.
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.
