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

Glanville Environmental is a well-established UK-based civil engineering and drainage services company operating since 1983, with a strong regional presence in the South West and Midlands. The company offers a comprehensive range of services including drainage and sewer works, sewer rehabilitation, manhole construction, and specialized solutions such as trenchless and no-dig technologies. With over 180 employees and multiple depots, Glanville Environmental positions itself as a market leader with a commitment to sustainability and net zero initiatives. Technically, the website is built on WordPress with modern plugins such as Gravity Forms, Google Tag Manager, and CookieYes for consent management. The site demonstrates good SEO practices, mobile optimization, and accessibility features. Security measures include HTTPS enforcement and use of Google reCAPTCHA on forms, though some security headers could be improved. The security posture is solid with no evident vulnerabilities or exposed sensitive data. Privacy compliance is strong, featuring detailed cookie and privacy policies aligned with GDPR requirements. The company displays multiple ISO certifications and industry awards, enhancing trust and credibility. However, the absence of WHOIS domain registration data is a notable concern, as it conflicts with the active and professional nature of the website. This discrepancy lowers the overall trust score and suggests further verification of domain legitimacy is advisable. Overall, Glanville Environmental presents a professional and trustworthy digital presence with strong business and technical foundations, but domain registration transparency should be addressed to improve 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. 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

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

Glanville Environmental operates in the civil engineering and environmental services sector, targeting commercial and domestic clients primarily in the UK. The company leverages a diversified service portfolio across eight specialized divisions, enabling it to address a wide range of infrastructure and drainage needs. Their business model focuses on service excellence, innovation, and sustainability, as evidenced by their net zero commitment and multiple ISO certifications.

Their marketing ecosystem includes professional digital assets, social media engagement, and industry recognition, positioning them competitively in their market niche.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure form handling via Google reCAPTCHA. Cookie consent management is implemented with granular user controls, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options indicates room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Incident response and security policy documentation are not publicly available, which could be enhanced to improve transparency and readiness. Overall, the security measures are adequate for the business type but could benefit from additional hardening and formalized security disclosures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a formal security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly audit and update WordPress core and plugins to mitigate potential vulnerabilities.
  4. Consider creating a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Address the WHOIS domain registration data gap to improve domain legitimacy and trustworthiness.

The site is optimized for mobile devices and demonstrates good SEO practices with Yoast SEO plugin integration. Performance is moderate with lazy loading and asynchronous script loading. Accessibility features such as ARIA roles and keyboard navigation support are present. The site uses reCAPTCHA to protect forms from spam. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is robust and supports the business needs effectively, though some security header enhancements and performance tuning could be considered.
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.
