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

Concrete.com is a niche informational website focused on providing comprehensive resources about concrete, including calculators, forums, and industry articles. Established in 1999, it serves contractors, industry professionals, and DIY enthusiasts with practical tools and expert advice. The business model is primarily content-driven with advertising revenue from Google Adsense and affiliate partnerships. The site maintains a consistent brand presence and long domain history, supporting its credibility in the concrete industry niche. Technically, the site runs on WordPress with standard plugins and Cloudflare DNS but lacks advanced security headers and cookie consent mechanisms. Performance and mobile optimization are basic but functional. Security posture is moderate with HTTPS enabled but missing DNSSEC and security headers. Privacy compliance is minimal with a basic privacy policy but no cookie banner or GDPR indicators. No direct company contact emails or phone numbers are published, limiting direct communication channels. Overall, the site is moderately professional and trustworthy but could improve in security and privacy compliance.

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 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

The website occupies a specialized market segment providing concrete-related information and tools. Its competitive advantage lies in its long-standing presence and comprehensive calculators and forums that attract a targeted audience. Revenue streams include advertising and affiliate marketing. The partnership ecosystem includes recognized industry organizations and commercial advertisers. Growth indicators are limited but the site maintains steady content updates and community engagement via forums. Strategic observations suggest opportunities to enhance user engagement, improve privacy compliance, and strengthen security posture to build greater trust and expand market reach.

Security posture

The security maturity level is moderate. HTTPS is enforced, and domain transfer is protected, but DNSSEC is not enabled, and no security headers such as CSP, HSTS, or X-Frame-Options are detected. There is no visible incident response or security policy published, and no dedicated security contact channels. The site uses standard WordPress plugins, which may pose risks if not regularly updated. Privacy compliance gaps exist, notably the absence of cookie consent mechanisms and GDPR indicators. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate for an informational site but requires enhancements to meet modern standards and regulatory requirements.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Implement security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options.
  3. Add a cookie consent banner and update privacy policy to reflect GDPR compliance.
  4. Publish a clear security policy and incident response contact information.
  5. Enhance mobile optimization and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built on WordPress 6.8.2 with jQuery 3.7.1 and uses Google Adsense for monetization. It employs Cloudflare DNS but does not use Cloudflare's WAF or security challenge features. The site includes custom JavaScript for concrete calculators and uses standard CSS stylesheets. Performance is moderate with some legacy scripts and inline JavaScript. SEO is basic with meta tags but no structured data like JSON-LD or Open Graph tags detected. Accessibility and mobile responsiveness are basic but could be improved. The technical stack is stable but dated, indicating potential technical debt and modernization opportunities.
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.
