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

GC Rieber Minerals is a Norwegian-based company specializing in minerals and salt solutions serving diverse markets such as road maintenance, fishery, aquaculture, industrial applications, food production, and agriculture. The company emphasizes sustainability and circular economy principles, owning prominent brands like Norsal and Stradasalt. Their website reflects a mature digital presence with comprehensive content, multimedia integration, and clear navigation. Technically, the site is built on WordPress with modern plugins and SEO tools, offering good performance and accessibility. Security posture is solid with HTTPS and cookie consent mechanisms, though some security headers could be improved. The absence of WHOIS registration data is a concern but does not detract significantly from the overall legitimacy given the professional site and external references. Strategic recommendations include enhancing security headers, maintaining up-to-date software, and verifying domain registration transparency.

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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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
    • 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';…

  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

The company holds a strong position in the Nordic minerals and salt market, targeting industrial and municipal clients with a focus on sustainable and innovative products. Their business model is B2B, leveraging brand ownership and product development to maintain competitive advantage. The presence of multiple offices across Norway, Sweden, Denmark, Iceland, and the Faroe Islands indicates regional reach and operational scale. Partnerships and subsidiaries such as Norsal and Stradasalt enhance market penetration. The website content and external links suggest a stable revenue stream from salt and mineral products for various industrial applications. Growth indicators include emphasis on circular economy and sustainability, aligning with global trends. The company maintains a professional online presence with clear contact points and compliance documentation.

Security posture

The website demonstrates a good security baseline with enforced HTTPS, cookie consent management, and no visible exposure of sensitive data. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, which could improve defense-in-depth. No vulnerable or outdated libraries were identified in the HTML content. The site uses reputable plugins and scripts, and no signs of malware or phishing were found. Incident response and vulnerability disclosure information are not present, which is common but could be enhanced for transparency. Overall, the security posture is good but could benefit from additional hardening and documented policies.

Recommendations

  1. Implement and enforce security headers such as CSP, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities and maintain compatibility.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to improve transparency and incident response readiness.
  4. Verify and update WHOIS domain registration information to improve trust and legitimacy perception.
  5. Enhance privacy and security culture by providing clear contact channels for security incidents and data protection inquiries.

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.
