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

JOS Structures Limited is a Midlands-based specialist contractor established in 2004, focusing on reinforced concrete structures within the civil engineering sector. The company serves multiple industries including highways, water environment, rail, commercial, residential, and specialist industries, positioning itself as a reliable and experienced FRC contractor in the UK market. Their website reflects a professional business with clear service offerings and client testimonials, targeting construction and infrastructure professionals. Technically, the website employs JavaScript and Google Tag Manager for analytics and tracking, with responsive design elements ensuring good mobile optimization. The CMS appears to be a custom solution provided by itseeze. While the site is well-structured and SEO-optimized, there is room for improvement in accessibility and performance tuning. From a security perspective, the site uses HTTPS and has a cookie consent mechanism, but lacks visible HTTP security headers and explicit security policies. No forms or sensitive data exposure were detected, indicating a moderate security posture. The absence of WHOIS registration data raises concerns about domain legitimacy and registration status, which should be investigated further to ensure trustworthiness. Overall, the website is professional and trustworthy in content and design but requires improvements in security headers and domain registration transparency to enhance its security posture and credibility.

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

5 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 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Domain Expires Soon

      Domain expires in 2 days

      What to do: Renew domain registration before expiration

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.

Business context

Business profile

JOS Structures Limited operates as a specialized service provider in the civil engineering construction sector, focusing on reinforced concrete contracting. Their market positioning is that of a trusted Midlands-based contractor with a solid client base across the UK. The business model revolves around project-based contracting services with a focus on quality, safety, and timely delivery. Revenue streams likely derive from contracts in highways, water environment, rail, and commercial construction projects. The company targets infrastructure developers, civil engineers, and construction firms. Growth indicators include a diverse project portfolio and active client testimonials. The partnership ecosystem includes local golf course sponsorships and a LinkedIn presence, indicating community engagement and professional networking. Strategic observations suggest a stable medium-sized enterprise with opportunities to strengthen digital presence and security compliance.

Security posture

The current security maturity level is moderate. The website uses HTTPS and implements a cookie consent mechanism, indicating awareness of privacy compliance. However, the absence of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. There is no visible incident response or vulnerability disclosure information, which limits readiness for security incidents. Compliance with GDPR is indicated by privacy and cookie policies, but explicit data protection officer contact or security frameworks are not present. The security culture appears basic, with room for improvement in formalizing security policies and enhancing technical controls.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Verify and update domain WHOIS registration to ensure transparency and trustworthiness.
  3. Publish explicit security and incident response policies including contact channels for security issues.
  4. Conduct regular audits of third-party scripts and tracking tools to minimize vulnerabilities.
  5. Enhance accessibility features and performance optimization to improve user experience and compliance.

Technical notes

Notes

The website is built on a custom CMS platform provided by itseeze, utilizing JavaScript and Google Tag Manager for analytics and tracking. The site is responsive and mobile-optimized with a clear navigation structure and SEO-friendly meta tags. Performance is moderate, with potential improvements in loading speed and accessibility compliance. The lack of detected HTTP security headers and incomplete WHOIS data represent technical risks that could impact business operations and trust. Modernization opportunities include adopting security best practices and enhancing technical transparency. Overall, the infrastructure supports business needs but requires targeted improvements to reduce technical debt and security exposure.
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.
