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

Illingworth Brothers is a small, family-run business specializing in the manufacture and installation of traditional sash and case windows, wooden doors, and UPVC windows and doors primarily serving Edinburgh and the surrounding Lothian area. The company emphasizes quality craftsmanship with over 60 years of experience and offers a range of products designed to meet conservation and energy efficiency standards. The website reflects a professional and consistent brand image with clear contact information and customer testimonials, positioning the company as a trusted local specialist in home improvement products. Technically, the website employs common web technologies including jQuery, Google Analytics, Google reCAPTCHA for form security, and media players for enhanced user experience. The site is moderately optimized for mobile devices and SEO, with a clear navigation structure and relevant meta tags. However, there is no evidence of a CMS or advanced frameworks, and performance is moderate. Security measures include HTTPS and reCAPTCHA, but the absence of explicit security headers and detailed security policies indicates room for improvement. From a security perspective, the site shows moderate maturity with basic protections in place but lacks comprehensive security headers and incident response information. The WHOIS data is unavailable due to domain naming errors, which raises concerns about domain registration consistency and trustworthiness. No critical vulnerabilities or malware indicators were found, but the site would benefit from enhanced security practices and transparency. Overall, the website is functional, professional, and trustworthy for its business purpose but should address domain registration inconsistencies and strengthen security posture to improve trust and compliance.

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.

Priority findings

6 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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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

Illingworth Brothers operates in the home improvement sector focusing on window and door manufacturing and installation. Their competitive advantage lies in their long-standing local presence, family business model, and specialization in traditional sash windows combined with modern double glazing technology. The business targets homeowners and property managers in Edinburgh and nearby regions, offering both wooden and UPVC products. Revenue streams likely come from direct sales and installation services. The company maintains a modest digital footprint with no visible social media presence or advanced e-commerce capabilities. Partnerships or subsidiaries are not evident. Growth indicators include a well-maintained website with testimonials and a factory visit option, suggesting a focus on quality and customer trust. Strategic observations highlight the need for improved domain registration clarity and enhanced digital security to support business credibility.

Security posture

The website demonstrates a basic to moderate security posture. It uses HTTPS and integrates Google reCAPTCHA to protect its contact form from spam and abuse. However, the absence of key HTTP security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces its defense against common web attacks. No incident response or security policy information is provided, limiting transparency and preparedness. The WHOIS data is missing due to domain registration issues, which could be a red flag for domain legitimacy. There are no signs of exposed sensitive data or vulnerable libraries in the HTML source. Overall, while no critical vulnerabilities are apparent, the site would benefit from implementing stronger security headers, publishing security policies, and clarifying domain registration details to enhance trust and compliance.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Verify and correct domain registration details to ensure WHOIS data is accurate and consistent with the business identity.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and preparedness.
  4. Regularly audit and update third-party libraries and scripts to avoid potential vulnerabilities.
  5. Enhance privacy compliance by expanding the privacy policy details and clearly documenting data retention and user rights.

Technical notes

Notes

The website is built using standard web technologies such as HTML5, CSS, and JavaScript, with jQuery as the primary JavaScript library. It uses Google Fonts for typography and integrates Google Analytics and Google Tag Manager for traffic analysis. The site includes Google reCAPTCHA for form security and jPlayer for audio playback. The navigation is structured with dropdown menus and a responsive design approach, though no specific CMS or backend platform is identified. Performance is moderate with some asynchronous script loading. Accessibility features are basic, with some meta tags for viewport and format detection. SEO is supported by relevant meta keywords and descriptions. The site lacks advanced security headers and detailed technical metadata. Hosting provider and SSL certificate details are not discernible from the HTML content alone.
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.
