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

End Systems Limited is a UK-based specialist engineering and commissioning company serving the construction sector since 1976. They provide a range of services including commissioning management, HVAC testing, building services surveys, technical documentation, and videography. The company positions itself as a trusted partner to leading construction groups nationwide, supported by multiple industry accreditations and client testimonials. The website reflects a professional and well-established business with a clear focus on quality and innovation. Technically, the website is built on WordPress and leverages modern JavaScript libraries such as jQuery, Slick Carousel, and AOS for animations. SEO is enhanced through Yoast SEO plugin, and Google Tag Manager is used for analytics and tracking. The site is mobile-optimized and accessible, with good performance and clear navigation. However, some security best practices such as security headers and cookie consent mechanisms are missing. From a security perspective, the site uses HTTPS and does not expose sensitive data. The lack of security headers and absence of a vulnerability disclosure or incident response policy page are areas for improvement. WHOIS data could not be retrieved due to querying the subdomain rather than the domain, limiting domain registration trust assessment. Overall, the security posture is moderate but can be enhanced with additional controls. The overall risk is low given the professional nature of the business and website, but improvements in privacy compliance and security hardening are recommended to strengthen trust and regulatory adherence.

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. 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

  2. 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

  3. 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

      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

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

End Systems operates in the construction engineering sector with a focus on commissioning and technical services. Their competitive advantage lies in their long-standing industry experience since 1976, comprehensive service offerings, and recognized accreditations such as Constructionline and Cyber Essentials. The business model is service-oriented, targeting construction firms and project groups across the UK. Growth indicators include recent projects and innovations highlighted on the site. The company maintains a partnership ecosystem with reputable clients and suppliers, enhancing market credibility. Strategic observations suggest a focus on innovation and digital transformation through proprietary tools like EndCheck and EndDocs, positioning them well for future market demands.

Security posture

The security maturity of End Systems is moderate. The website enforces HTTPS and avoids exposing sensitive information. However, the absence of key security headers (CSP, HSTS, X-Frame-Options) reduces defense-in-depth. No incident response or vulnerability disclosure information is publicly available, which may impact transparency and readiness. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism detected. The use of Google Tag Manager introduces moderate tracking, requiring clear user consent for GDPR compliance. Overall, the security culture appears professional but could benefit from formalized policies and technical enhancements to meet higher compliance standards such as ISO 27001 or NIST.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, and X-Frame-Options to enhance browser security.
  2. Deploy a cookie consent banner and detailed cookie policy to ensure GDPR compliance and improve user privacy transparency.
  3. Publish an incident response and vulnerability disclosure policy page to demonstrate security readiness and encourage responsible reporting.
  4. Conduct a security audit to identify and remediate any potential vulnerabilities in third-party scripts and plugins.
  5. Enhance WHOIS domain registration data accuracy by querying the correct domain (endsystems.co.uk) and ensuring registration details are up to date.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery, Slick Carousel for sliders, and AOS for scroll animations. SEO is managed via Yoast SEO plugin, and Google Tag Manager is used for analytics and marketing. The site loads moderately fast with responsive design and good accessibility features. There is no evidence of outdated or vulnerable libraries. The hosting provider is not explicitly identified. Technical debt appears low, but opportunities exist to improve security headers and privacy compliance. Overall, the technical infrastructure supports a professional and user-friendly experience aligned with business goals.
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.
