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

ESG (Essex Services Group LTD) is an employee-owned company specializing in building services within the construction industry in the United Kingdom. The company emphasizes sustainability, innovation, and employee empowerment, positioning itself as a leader in its market segment. Their services include comprehensive building services solutions, design engineering, project delivery, offsite innovation, and BIM-compliant processes, with a focus on sectors such as residential, commercial, specialist projects, technology, data centres, and life sciences. Technically, the website employs modern front-end technologies including HTML5, CSS3, JavaScript, Swiper.js for carousels, and GLightbox for media display. The site is hosted with GoDaddy.com, LLC and uses HTTPS with a good SSL configuration. Mobile optimization and SEO practices are good, though accessibility features are basic. No CMS or backend platform was detected from the provided data. From a security perspective, the website benefits from HTTPS and domain registration protections but lacks DNSSEC and visible security headers. There is no published security policy or incident response contact information, and no vulnerability disclosure mechanism is present. Privacy compliance is strong with comprehensive privacy and cookie policies and an active cookie consent banner. No contact emails or phone numbers are directly listed, with contact primarily via a form. No suspicious or malicious content was detected. Overall, ESG's website is professional, trustworthy, and well-aligned with its business goals. Recommendations include enabling DNSSEC, implementing security headers, publishing a security policy and incident response contacts, and considering a vulnerability disclosure program to enhance security posture 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. 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 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

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

ESG operates in the building services sector with a medium-sized, employee-owned business model focused on sustainability and innovation. Their market positioning as a leader is supported by a long trading history since 2016 and a broad service offering across multiple construction sectors. The company targets construction industry clients requiring comprehensive building services, including design, delivery, and maintenance. Their published policies and reports (privacy, cookies, modern slavery, gender pay gap) indicate a mature organizational approach. The partnership ecosystem includes LinkedIn presence but no other partner domains were identified. Growth indicators include a focus on offsite innovation and BIM compliance, aligning with modern construction trends.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and domain registration protections in place. However, the absence of DNSSEC, security headers, and published security policies indicates room for improvement. No exposed sensitive data or vulnerable libraries were detected. The lack of incident response contact channels and vulnerability disclosure mechanisms suggests limited readiness for security incidents. Privacy compliance is strong, with cookie consent and detailed policies. Overall, the security posture is adequate but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Enable DNSSEC to strengthen DNS security and prevent spoofing.
  2. Implement standard security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Publish a dedicated security policy and provide clear incident response contact information.
  4. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Notes

The website uses a modern front-end technology stack with JavaScript libraries like Swiper.js and GLightbox for interactive elements and media handling. Fonts are served via Adobe Typekit. The site is hosted with GoDaddy.com, LLC, with domain registration dating back to 2016. Performance is moderate with good mobile optimization and SEO practices. No CMS or backend platform was detected, suggesting a custom or static site approach. Technical risks include lack of DNSSEC and missing security headers, which could be addressed to improve security posture. The site is well-structured with clear navigation and consistent branding.
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.
