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

Stratton Glass & Windows Ltd is a well-established local home improvement company based in Norfolk, UK, specializing in the supply and installation of premium aluminium and uPVC windows, composite doors, conservatories, and home extensions. With over 40 years of experience, the company positions itself as a trusted partner for homeowners in Norfolk and Suffolk, offering quality products backed by a 10-year insurance-backed warranty and recognized industry certifications such as FENSA and GGF. Their services include a wide range of window and door types, conservatory designs, and roof replacement solutions, targeting residential customers seeking durable and energy-efficient home improvements. Technically, the website is built on ASP.NET WebForms using the Bongo CMS platform, incorporating legacy JavaScript libraries like jQuery 1.4.4 and MooTools, alongside modern tools such as Facebook Pixel for marketing and tracking. The site is mobile-optimized with good SEO practices and includes a cookie consent mechanism compliant with GDPR. However, some outdated libraries and missing security headers suggest room for technical modernization and enhanced security hardening. From a security perspective, the website enforces HTTPS, uses captchas on forms, and provides clear privacy and cookie policies, reflecting a mature privacy posture. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of WHOIS data for the queried subdomain is due to domain naming rules, but the website content and contact information strongly indicate legitimacy and consistency with the business claims. Overall, Stratton Glass & Windows Ltd presents a professional and trustworthy online presence with solid business credibility and a good security posture. Strategic improvements in updating legacy scripts, implementing security headers, and publishing explicit security policies would further enhance their digital maturity and risk management.

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

The company operates in the home improvement sector, focusing on windows, doors, conservatories, and related building services in the Norfolk and Suffolk regions. Their competitive advantages include a long-standing family ownership since 1979, a comprehensive 10-year warranty, and multiple industry accreditations. The business model centers on direct supply and installation, managing projects end-to-end from design to completion. Revenue streams likely derive from product sales, installation services, and bespoke home extensions. The target customer segment is residential homeowners seeking quality and energy-efficient home improvements. The company maintains an active social media presence and uses digital marketing tools to engage customers. Growth indicators include a broad service portfolio and a showroom presence. No parent or subsidiary companies were identified, indicating an independent small business operation.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and use of captchas to protect forms from automated abuse. Privacy and cookie policies are clearly presented with user consent mechanisms, indicating GDPR compliance. However, the use of outdated JavaScript libraries such as jQuery 1.4.4 poses potential security risks due to known vulnerabilities in older versions. The absence of explicit security headers like Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is published, which could hinder coordinated security issue handling. Overall, the security maturity is good for a small business but could be improved by updating dependencies, adding security headers, and publishing security policies.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  5. Regularly audit and test website security posture and privacy compliance to maintain high standards.

Technical notes

Notes

The website is built on ASP.NET WebForms with the Bongo CMS platform, utilizing legacy JavaScript libraries including jQuery 1.4.4 and MooTools, alongside modern tools like Facebook Pixel and Conditionizr. The site includes responsive design features and mobile optimization, with good SEO meta tags and Open Graph data. Hosting details are not explicitly identified, but video content is served via Cloudflare Stream. Performance is moderate, with potential improvements by updating scripts and optimizing assets. Accessibility features are basic but present. The site uses multiple external resources including Google Fonts and social media integrations. Overall, the technical infrastructure is functional but shows signs of aging technology that could benefit from modernization to improve security, performance, and maintainability.
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.
