Risk levelMedium

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

Emineral A/S operates as a specialized supplier and quality monitor of mineral byproducts sourced from Danish combined heat and power plants. Their core business revolves around the sale of fly ash and bio ash products tailored for concrete and asphalt production, targeting B2B customers in the construction and energy sectors. The company maintains a professional online presence with clear product offerings, ordering mechanisms, and compliance with European data privacy regulations. Technically, the website is built on the Umbraco CMS platform using Microsoft ASP.NET technologies, enhanced by Cloudflare for CDN and security. The site demonstrates good mobile optimization, accessibility, and SEO practices. Security posture is solid with HTTPS enforced and a comprehensive cookie consent mechanism, though it lacks some advanced security headers and explicit incident response information. The absence of WHOIS data transparency slightly reduces domain trust but does not detract significantly from the overall legitimacy. Strategic recommendations include enhancing security headers, publishing security policies, and improving WHOIS transparency to bolster trust further.

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

4 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 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. 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

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

Emineral holds a niche position within the Danish energy and construction industries, leveraging byproducts from power plants to supply mineral materials essential for infrastructure projects. Their business model is focused on direct sales and quality assurance, supported by a digital ordering platform and detailed product information. The company benefits from partnerships with major Danish energy providers, as indicated by logos on the site, enhancing credibility. Revenue streams likely derive from bulk mineral product sales and associated services. The website content and structure suggest a medium-sized enterprise with a focused market segment. Growth potential exists through expanded digital engagement and enhanced compliance transparency. The partnership ecosystem includes recognized energy companies and cookie consent service providers, indicating a professional operational environment.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, a detailed cookie consent banner compliant with GDPR, and no visible exposure of sensitive data. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No vulnerability disclosures or incident response contacts are published, which could hinder rapid response to security events. The use of Cloudflare provides additional protection layers, but explicit documentation of security policies and procedures is lacking. Overall, the security maturity is good but could be elevated by adopting best practices in header implementation and transparency in incident management.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page outlining data protection, incident response, and vulnerability disclosure procedures.
  3. Enhance WHOIS transparency by ensuring domain registration details are complete and publicly accessible to improve trustworthiness.
  4. Provide clear incident response contact channels such as security@ or abuse@ email addresses for timely communication.
  5. Regularly audit and update third-party libraries and frameworks to prevent vulnerabilities and maintain compliance.

Technical notes

Notes

The website is built on a modern technology stack featuring Umbraco CMS and Microsoft ASP.NET, supported by Cloudflare CDN for performance and security. The site uses jQuery and Umbraco Forms for interactive elements and data collection. Performance is moderate with responsive design and good accessibility features. SEO is supported by proper meta tags and Open Graph data, though structured data (JSON-LD) is absent. The site includes a comprehensive cookie consent mechanism with detailed cookie declarations, reflecting a strong focus on privacy compliance. Technical debt appears minimal, but opportunities exist to modernize security headers and enhance WHOIS data visibility to reduce risk and improve stakeholder confidence.
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.
