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

  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.

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

Byworth Boilers operates in the energy and manufacturing sectors, focusing on industrial steam and hot water boilers. Their business model integrates product manufacturing with value-added services such as installation, maintenance, and operator training, creating multiple revenue streams. The company leverages its long history and expertise to maintain a strong market position in the UK. The website highlights customer testimonials and case studies, reinforcing credibility. Partnerships with organizations like Made in Britain and professional marketing support indicate a mature business ecosystem. The target customer segment includes industrial operators seeking energy-efficient boiler solutions. Growth indicators include a comprehensive service offering and digital presence with active social media channels.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data. The use of Microsoft Application Insights and Leadfeeder indicates active monitoring and analytics. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No incident response or vulnerability disclosure information is published, which could impact transparency. Overall, the security measures are adequate for the business type but could be enhanced to align with best practices and regulatory expectations.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  3. Conduct regular audits of third-party scripts and tracking tools to mitigate potential vulnerabilities.
  4. Enhance website accessibility features to meet WCAG standards and improve user experience for all visitors.
  5. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting and improve security posture.

Technical notes

Notes

The website is built on the nopCommerce platform, leveraging jQuery, Font Awesome, and Typekit for frontend styling and functionality. Hosting on Microsoft Azure provides a reliable infrastructure with session affinity cookies observed. Performance is moderate with asynchronous loading of analytics and tracking scripts. The site is mobile-optimized with responsive menus and images. SEO is supported by meta tags and structured content. Some technical debt is noted in the lack of advanced security headers and limited accessibility features. Opportunities exist to modernize frontend frameworks and improve performance metrics further. Overall, the technical implementation supports business operations effectively with manageable risks.
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.
