The company specializes in delivering comprehensive mechanical and electrical packages for construction projects ranging from £50k to over £7m. Their services include plumbing, heating, air conditioning, fire alarms, security, data, PV, and plantroom installations. The business targets construction industry clients across the UK and maintains a strong market position supported by multiple industry certifications and a professional online presence. Technically, the website is built on the SeeCMS platform and utilizes a range of JavaScript libraries including jQuery, Slick Slider, and FontAwesome. The site is moderately optimized for performance and mobile devices, with basic SEO and accessibility features. Hosting is provided by NetHosted Ltd, consistent with the domain registration data. Analytics are implemented via Google Tag Manager and Google Analytics, with moderate user tracking. From a security perspective, the site uses HTTPS and shows no signs of exposed sensitive data or vulnerable libraries, though it lacks visible security headers and explicit security policies. The use of an outdated jQuery version and absence of cookie consent mechanisms indicate areas for improvement. No incident response or vulnerability disclosure information is present, which could be enhanced to improve security posture. Overall, the website is professional, trustworthy, and aligned with the company's business claims. Recommendations include updating JavaScript libraries, implementing security headers, adding cookie consent mechanisms, and publishing terms of service and security policies to strengthen compliance and 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

6 findings rated critical or high. Fix these first.

  1. 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
  2. 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
  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"

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

JH Shouksmith & Sons Ltd operates as a medium-sized, family-owned business in the energy and construction sectors, focusing on mechanical and electrical contracting services. Their competitive advantage lies in their long history, multi-generational leadership, and comprehensive service offerings for projects of varying sizes. Revenue streams likely derive from contracting services for commercial and industrial construction projects. The company targets construction project managers and developers across the UK. Their partnership ecosystem includes industry certification bodies and a web design partner (See Green). Growth indicators include a strong online presence and multiple certifications. Strategic observations suggest maintaining modernization of technical infrastructure and enhancing digital compliance to support continued market competitiveness.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. The use of an outdated jQuery version presents a potential vulnerability vector. No explicit incident response or security policies are published, limiting transparency and preparedness. GDPR compliance is partial, with privacy and cookie policies present but lacking active consent mechanisms. The security culture appears basic, with room for improvement in formalizing security practices and disclosures. Overall, the security posture is adequate for a medium-sized business but should be enhanced to mitigate risks and comply with evolving regulations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade JavaScript libraries, particularly jQuery, to the latest secure versions.
  3. Introduce an explicit cookie consent mechanism to comply with GDPR and enhance user privacy.
  4. Publish clear terms of service and incident response policies on the website.
  5. Establish a vulnerability disclosure program or security.txt file to improve transparency and security responsiveness.

Technical notes

Notes

The website is built on the SeeCMS content management system and leverages several JavaScript libraries such as jQuery 1.12.2, Slick Slider, and FontAwesome for UI and functionality. Fonts are loaded asynchronously via Adobe Typekit. Google Tag Manager is used for analytics integration. The site is hosted by NetHosted Ltd, consistent with WHOIS data. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. The technical stack is somewhat dated, notably the older jQuery version, which may pose security risks. Modernization opportunities include updating libraries, enhancing SEO with structured data, and improving accessibility compliance.
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.
