59/100

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

GCC is a large multinational company specializing in the production and distribution of cement, concrete, aggregates, and innovative construction products across Mexico, the United States, Latin America, and Canada. The company positions itself as a sustainable and innovative leader in the construction materials industry, targeting construction professionals and businesses. The website is built on WordPress with a modern tech stack including jQuery, Flickity, and integrates analytics and marketing tools such as Google Analytics, Google Tag Manager, and New Relic. While the site is professionally designed, mobile-optimized, and rich in content, a critical security gap exists due to the absence of a valid SSL certificate and HTTPS support. Security headers are partially implemented, and privacy compliance is well addressed with clear privacy and cookie policies including consent mechanisms. Contact information and business details are clearly presented, enhancing business credibility. Overall, the site demonstrates strong business and technical maturity but requires urgent remediation of SSL/TLS issues to improve security posture and user 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

1 finding 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

GCC operates in the energy and manufacturing sectors with a focus on construction materials. The company offers a broad portfolio including cement, ready mix concrete, specialty products, energy solutions, building materials, and asphalt. GCC targets construction industry stakeholders in North America and Latin America, leveraging a vertically integrated business model. The company maintains a strong market position supported by certifications such as Great Place to Work and Energy Star. The website reflects a mature digital presence with integrated marketing and analytics tools, supporting customer engagement and investor relations. Partnerships and subsidiary domains like customer portals and job application sites indicate a well-structured ecosystem. GCC's growth and sustainability focus are evident, positioning it as a key player in its industry.

Security posture

The website's security posture is currently weak due to the lack of a valid SSL certificate and absence of HTTPS, exposing users to potential data interception risks. While some security headers like Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options are present, critical TLS protocols and cipher suites are not enabled. There is no OCSP stapling or session resumption configured, which affects both security and performance. Privacy policies and cookie consent mechanisms are properly implemented, indicating compliance awareness. However, the missing SSL certificate is a critical vulnerability that must be addressed immediately to protect user data and maintain trust. No evidence of incident response or vulnerability disclosure policies was found, suggesting areas for improvement in security governance.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and strong cipher suites to enhance encryption.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Expand security headers to include X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
  5. Develop and publish an incident response and vulnerability disclosure policy to improve security transparency and readiness.

Notes

The website is built on WordPress CMS with a modern frontend stack including jQuery and Flickity for UI components. It uses Yoast SEO for search engine optimization and integrates Google Analytics and New Relic for performance monitoring and analytics. Hosting is provided via Pantheon with nginx and varnish caching layers. The site is mobile-optimized and features a professional design with clear navigation. However, performance metrics were not available, and SSL/TLS configuration is critically lacking. The site uses several third-party scripts for cookie consent and social sharing. Overall, the technical infrastructure is solid but requires urgent security upgrades to SSL/TLS and potential performance tuning.
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.
