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

Calder Textiles is a well-established UK-based manufacturer specializing in luxury woollen yarns for various sectors including contract, residential, cruise ships, and aviation. The company emphasizes high-quality bespoke products using predominantly British, New Zealand, and Scandinavian wools. Their website reflects a professional and consistent brand image, targeting business customers in the textile manufacturing industry. Technically, the website is built using modern frameworks such as Astro and Bootstrap, hosted likely behind Cloudflare, and demonstrates good mobile optimization and SEO practices. Security-wise, the site uses HTTPS and avoids exposing sensitive data, but lacks explicit security headers and published security policies, which are recommended for enhanced protection and compliance. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the site is credible and trustworthy with a strong business presence, though improvements in security and privacy transparency would strengthen its 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  2. GDPR outside view

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

    • 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

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

The company operates in the manufacturing sector, focusing on woollen yarn production with a niche in luxury and bespoke products. Their market position is strong within the UK textile industry, supported by a long domain history and a registered company number. The business model revolves around supplying high-quality yarns to diverse industries globally. The website indicates a small-sized enterprise with a family-owned heritage. Partnerships include the design agency Day Eight. No direct revenue streams or affiliate programs are evident on the site. The absence of social media links suggests a focus on direct B2B relationships rather than broad consumer marketing.

Security posture

Calder Textiles demonstrates a moderate to good security posture with HTTPS enforced and no visible sensitive data leaks. However, the lack of security headers such as Content-Security-Policy and absence of a published security or incident response policy are gaps that could be exploited or reduce trust. No vulnerability disclosures or security.txt files are present, limiting transparency for security researchers. The site does not implement cookie consent mechanisms, which may impact GDPR compliance. Overall, the security maturity is adequate for a small manufacturing business but could be improved to meet higher compliance and security standards.

Recommendations

  1. Implement comprehensive 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 and detailed cookie policy to comply with GDPR and other privacy regulations.
  3. Publish a formal security policy and incident response contact information to improve transparency and readiness.
  4. Consider creating a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.

Technical notes

Notes

The website uses Astro framework version 2.10.7 and Bootstrap for responsive design, indicating a modern and modular front-end architecture. Hosting appears to be via Cloudflare, providing CDN and security benefits. Performance is moderate with lazy loading of images and video content, though no explicit performance metrics are available. The site is mobile optimized with responsive navigation and layout. SEO is supported by meta description and structured navigation. No CMS is detected, suggesting a static or custom-built site. There is no evidence of outdated or vulnerable libraries. Technical debt appears low, but the absence of security headers and privacy mechanisms are notable technical gaps.
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.
