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

Overhead Line Fittings (U.K.) Limited is a UK-based manufacturer specializing in electrical fittings and accessories for overhead transmission and distribution power lines. Established in 1961, the company serves major clients such as the National Grid and Distribution Network Operators, offering bespoke design solutions, manufacturing, and in-house testing facilities. Their product range includes insulators, conductor accessories, safety and maintenance products, and electrical joining paste. The company positions itself as a leading UK manufacturer with a medium-sized operation focused on the energy sector. Technically, the website is built on WordPress and utilizes common web technologies such as jQuery, AOS for animations, Owl Carousel for product displays, and Font Awesome for icons. The site is mobile-optimized with good navigation and SEO practices, though performance is moderate. No advanced frameworks or hosting details were identified. Security-wise, the site enforces HTTPS but lacks security headers and cookie consent mechanisms. No vulnerabilities or exposed sensitive data were detected, but improvements are recommended to enhance security posture and privacy compliance. The WHOIS data for the domain is unavailable due to a domain naming rules violation error from Nominet UK, which is inconsistent with the active website presence. Despite this, the website provides clear contact information, company registration details, and accreditation logos, supporting its legitimacy. Overall, the site is professional and trustworthy but would benefit from enhanced security and privacy features to align with best practices and regulatory requirements.

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. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

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 energy sector, focusing on manufacturing and supplying electrical fittings for overhead power lines. Its longstanding history since 1961 and relationships with major industry players like National Grid and DNOs indicate a strong market position. The business model centers on product manufacturing combined with design and testing services, targeting contractors and utilities involved in power line installation and maintenance. The website reflects a medium-sized enterprise with consistent branding and clear trust signals such as company registration and accreditation. No evident partnerships or subsidiaries were identified from the website content or linked domains. The absence of social media and analytics tools suggests a conservative digital marketing approach.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces protection against common web attacks. No cookie consent or privacy banners are present, indicating partial GDPR compliance. No incident response or security policy information is published, limiting transparency. The site uses standard third-party libraries without known vulnerabilities, and no sensitive data exposure was detected. The WHOIS inconsistency raises a minor trust concern but does not directly impact site security. Overall, the security posture is adequate but requires enhancements to meet higher compliance and protection standards.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and update privacy policy to explicitly address GDPR compliance and user data handling.
  3. Publish a security policy and provide incident response contact information to improve transparency and readiness.
  4. Regularly audit and update third-party libraries and scripts to avoid potential vulnerabilities.
  5. Consider registering the domain correctly with Nominet UK to resolve WHOIS inconsistencies and improve trustworthiness.

Technical notes

Notes

The website is built on WordPress 6.2.9, leveraging jQuery, AOS for scroll animations, Owl Carousel for product sliders, and Font Awesome for icons. Google Fonts are used for typography. The site loads external scripts from trusted CDNs such as ajax.googleapis.com and unpkg.com. The design is responsive and mobile-friendly with good navigation clarity. Performance is moderate, likely due to multiple external resources and animations. No advanced frameworks or hosting details were identified. The site lacks modern security headers and cookie consent mechanisms, which are technical debt areas. Overall, the technical implementation is solid for a medium-sized business but could benefit from performance optimization and enhanced security configurations.
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.
