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

TJ Williams Ltd is a well-established UK-based manufacturer specializing in precision handcrafted pressure, level, and temperature instrumentation with over 150 years of industry presence. The company offers a comprehensive range of products including pressure gauges, calibration and repair services, bespoke designs, and acts as an official distributor for Kobold UK. Their market position is strong within the industrial manufacturing sector, targeting engineers and industrial clients requiring reliable instrumentation solutions. Technically, the website is built on a modern WordPress CMS with WooCommerce integration, leveraging Themify Ultra theme and jQuery libraries. The site is hosted via Cloudflare, ensuring good performance and security at the network level. Mobile optimization and SEO practices are well implemented, although accessibility features could be improved. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks several recommended security headers and a cookie consent mechanism, which impacts GDPR compliance. No explicit security policies or incident response contacts are published, indicating room for improvement in security transparency and readiness. Overall, the website is professional, trustworthy, and business-focused with a solid technical foundation. Strategic enhancements in privacy compliance and security best practices would further strengthen the company's digital maturity and customer trust.

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

7 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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

TJ Williams Ltd operates in the manufacturing sector, focusing on precision instrumentation for pressure, level, and temperature measurement. Their competitive advantage lies in their long-standing history, bespoke manufacturing capabilities, and official partnership with Kobold UK. The business model combines product manufacturing with value-added services such as calibration, repair, and technical support. Revenue streams likely include direct product sales, service contracts, and distribution partnerships. The target customer segments are industrial clients, engineers, and companies requiring specialized instrumentation. Growth indicators include a comprehensive product catalog, active customer testimonials, and ISO certification. The partnership ecosystem includes Kobold Instruments Ltd, enhancing product offerings and market reach. Operationally, the company demonstrates a mature market presence with a focus on quality and customer service.

Security posture

The current security posture of the TJ Williams website is moderate. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web attacks. The site does not display a cookie consent banner, which is a compliance gap under GDPR. No public security policy or incident response contact information is available, limiting transparency and preparedness for security incidents. The use of up-to-date WordPress and WooCommerce versions is positive, but no explicit mention of vulnerability management or security audits is found. Overall, while no critical vulnerabilities are evident, the site would benefit from enhanced security controls and compliance measures to reduce risk and improve trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  2. Add a cookie consent banner and cookie policy to comply with GDPR and ePrivacy Directive requirements.
  3. Publish a clear security policy and provide incident response contact information to improve transparency and readiness.
  4. Conduct regular security audits and vulnerability assessments to identify and remediate potential risks.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on a robust and widely-used WordPress platform with WooCommerce for e-commerce capabilities. The Themify Ultra theme provides a modern and responsive design, optimized for mobile devices. Performance is enhanced by Cloudflare hosting and caching mechanisms, resulting in fast load times. The site uses Google Tag Manager and Google Analytics for tracking and marketing insights. JavaScript libraries such as jQuery are employed for interactive features. While the technical infrastructure is solid, there is an opportunity to modernize further by implementing progressive web app features and improving accessibility compliance. Technical debt appears minimal, but security enhancements are recommended to mitigate risks associated with outdated or missing security controls.
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.
