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

Filon Products Ltd is a well-established UK manufacturer specializing in GRP (Glass Reinforced Polyester) products for roofing, cladding, and construction industries. Founded in 1957, the company holds a leading market position with a broad product portfolio including rooflights, sheets, valley troughs, and refurbishment solutions. Their business model focuses on manufacturing and supplying durable, innovative GRP products to construction professionals and specifiers. The website reflects a professional and consistent brand image with comprehensive product information and strong trust indicators such as certifications and social media presence. Technically, the website is built on WordPress with modern technologies including Tailwind CSS, Google Tag Manager, Microsoft Clarity, and CookieYes for consent management. The site is fast, mobile-optimized, accessible, and SEO-friendly, demonstrating a mature digital infrastructure. Privacy compliance is well addressed with clear privacy and cookie policies and user consent mechanisms. From a security perspective, the site enforces HTTPS and uses cookie consent management effectively. However, there is room for improvement by implementing additional security headers and publishing explicit security policies or incident response information. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website and business present a low-risk profile with strong credibility and compliance. The WHOIS lookup failure is due to querying a subdomain rather than the registered domain and does not detract from the legitimacy of the business. Strategic recommendations include enhancing security headers, publishing a security policy, and adding vulnerability disclosure mechanisms to further strengthen trust 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

2 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

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

Filon Products Ltd operates in the manufacturing sector with a focus on GRP products for construction. Their competitive advantage lies in decades of experience, industry-leading standards, and a comprehensive product range tailored to diverse roofing and cladding needs. The company targets construction professionals, specifiers, and industrial clients, leveraging a direct sales and technical support model. Growth indicators include active content marketing, case studies, and presence on NBS Source. Partnerships with industry associations and a strong digital presence support their market position. The company appears financially stable and reputable with a medium-sized operational scale.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and cookie consent mechanisms in place. Use of Google Tag Manager and Microsoft Clarity is managed with user consent, aligning with privacy regulations. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security is a gap. No visible vulnerabilities or exposed sensitive data were found. The lack of a published security policy or incident response contact limits transparency. Compliance with GDPR is evident through privacy and cookie policies. Overall, the security posture is solid but can be enhanced by adopting additional best practices and formalizing incident response procedures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response page to improve transparency and preparedness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and analytics tools to mitigate risks.
  5. Enhance monitoring and logging to detect and respond to potential security incidents promptly.

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.
