Risk levelMedium

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

Nyrstar is a well-established company specializing in the manufacturing and processing of zinc, lead, and other metals with a strong commitment to sustainability. The website presents a professional and comprehensive overview of their operations, products, and corporate responsibility initiatives, targeting industrial customers and partners in the metals and mining sectors. The company positions itself as a leading player with over 150 years of history, although domain registration data is not available to confirm this age. Technically, the website uses modern JavaScript frameworks such as Alpine.js and integrates analytics and tracking tools like Google Analytics and Hotjar. The presence of a cookie consent banner indicates some level of privacy compliance, but explicit privacy and terms of service policies are not found in the provided content. Security posture appears adequate with HTTPS usage and CSRF protections, but lacks visible security headers and incident response information. Overall, the website is functional and professional but would benefit from improved transparency in domain registration, privacy policies, and contact information to enhance trust and 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

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 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. 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

Nyrstar operates in the energy sector focusing on metals manufacturing and mining. Their business model revolves around sourcing, mining, and processing metals sustainably. The company targets industrial clients and contractors, offering a range of products including zinc alloys, lead alloys, and sulphuric acid. The website reflects a mature enterprise with a consistent brand and good content quality. However, the lack of WHOIS data and direct contact details may impact perceived credibility. The company uses advanced digital marketing and analytics tools, indicating a modern approach to customer engagement and data collection. There is no evidence of partnerships or subsidiaries from the provided data. Strategic growth appears focused on sustainability and operational excellence.

Security posture

The website employs HTTPS and includes CSRF token management in forms, which are positive security practices. Cookie consent mechanisms are implemented, supporting privacy compliance. However, no security headers such as Content Security Policy or HSTS are detected, and there is no published security policy or incident response contact information. The absence of a security.txt file or vulnerability disclosure program limits transparency for security researchers. No exposed sensitive data or vulnerable libraries were identified in the source. Overall, the security posture is moderate but could be significantly improved by adopting standard security headers, publishing security policies, and providing clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Disclose clear contact information including company emails and phone numbers for general and security-related inquiries.
  3. Implement and configure security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a security.txt file to facilitate vulnerability reporting and improve security transparency.
  5. Verify and update domain WHOIS information to reflect accurate registrant details and improve domain legitimacy.

Technical notes

Notes

The website is built using modern frontend technologies including Alpine.js and Laravel backend (inferred). It integrates third-party analytics and marketing tools such as Google Analytics, Google Tag Manager, Hotjar, and HubSpot forms. The site is mobile optimized with responsive images and video content. Performance is moderate with lazy loading and optimized assets via Blinkloader. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but could be enhanced. Hosting provider and CMS are not explicitly identified. Overall, the technical infrastructure supports a professional online presence but lacks some advanced security and compliance features.
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.
