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

3 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

  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 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';…

  3. 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

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

Holcim UK operates within the manufacturing sector, focusing on aggregates and concrete products for the construction industry. The rebranding from Aggregate Industries signals strategic alignment with the global Holcim Group brand. The website targets construction professionals and clients in the UK market. The business model is B2B manufacturing and supply, with a large enterprise scale. The company maintains a consistent brand image and uses modern digital marketing and analytics tools to engage its audience. No direct contact information or detailed business registration data is publicly presented on the analyzed page, but the presence of structured data and corporate branding supports credibility.

Security posture

The website employs HTTPS with strong SSL configuration, uses cookie consent tools compliant with GDPR, and integrates trusted analytics tags. However, it lacks visible security headers and explicit security or incident response policies on the analyzed page. No vulnerability disclosures or security.txt files were found. The absence of direct contact channels for security incidents is a gap. Overall, the security posture is good but could be improved by adding security headers, publishing security policies, and providing incident response contacts to enhance transparency and readiness.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response page with clear contact information.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Regularly audit third-party scripts and tags for security and privacy compliance.
  5. Enhance accessibility features and provide more comprehensive contact information for users.

Technical notes

Notes

The website is built on Drupal CMS and uses modern web technologies including Google Tag Manager, LinkedIn Insight, and OneTrust for cookie compliance. It loads multiple Google Fonts and Material Icons for UI consistency. The site is mobile-optimized and includes SEO best practices such as canonical links, meta descriptions, and Open Graph tags. Performance is moderate with asynchronous loading of analytics scripts. No hosting provider details were identified. The site could benefit from improved accessibility compliance and enhanced security headers to reduce technical risks.
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.
