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

Diamonds.co.nz is a New Zealand-based online retailer specializing in natural, certified diamonds and jewellery, with a strong emphasis on ethical sourcing and expert customer guidance. Established since 1984, the company positions itself as a trusted market leader offering a wide range of GIA certified diamonds, custom engagement ring creation, and value-added services such as live chat and Zoom consultations. The business model leverages an online-only presence to provide competitive pricing and a transparent purchasing experience. The website reflects a mature digital presence with comprehensive educational content and customer testimonials, reinforcing its credibility and market position. Technically, the website employs modern web technologies including Google Tag Manager, Google Analytics, Hotjar, and Tawk.to for live chat, indicating a sophisticated approach to user engagement and analytics. The site is mobile-optimized with responsive design and lazy loading for performance. However, some accessibility features could be improved, and no CMS or hosting provider details are explicitly detected. SEO practices appear solid with proper meta tags and structured data. From a security perspective, the site enforces HTTPS and uses secure forms for user login. While no critical vulnerabilities are evident, the absence of security headers and a cookie consent mechanism suggests room for improvement in compliance and security hardening. The lack of WHOIS data limits domain trust verification, but the presence of trusted industry partners and certifications supports legitimacy. Overall, the security posture is good but could benefit from enhanced transparency and incident response readiness. The overall risk assessment is moderate-low, with the main concerns being privacy compliance gaps and missing WHOIS transparency. Strategic recommendations include implementing security headers, adding cookie consent banners, publishing vulnerability disclosure policies, and improving accessibility. These steps will enhance trust, compliance, and security culture, supporting the company’s strong market position and customer confidence.

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

5 findings 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

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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 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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Diamonds.co.nz operates in the retail and e-commerce sector, targeting consumers in New Zealand seeking high-quality, ethically sourced diamonds and jewellery. The company’s competitive advantage lies in its extensive inventory of GIA certified diamonds, expert advisory services, and an online-only business model that enables competitive pricing. Revenue streams primarily come from diamond and jewellery sales, with additional value from consultation services and financing options. The partnership ecosystem includes reputable industry bodies such as GIA, IGI, and Jewellers & Watchmakers NZ, enhancing brand trust. Growth indicators include a well-maintained website with rich educational content and active marketing tools. Strategic observations highlight a focus on transparency, ethical sourcing, and customer education as key differentiators in a competitive market.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, secure login forms, and no visible exposure of sensitive data. The use of third-party services like Tawk.to and Hotjar is managed appropriately, though privacy compliance could be strengthened with a cookie consent mechanism. The absence of security headers such as Content-Security-Policy and X-Frame-Options is a notable gap that could expose the site to certain web-based attacks. No incident response or vulnerability disclosure information is provided, indicating a potential compliance and readiness gap. Data protection practices appear adequate but would benefit from explicit policies and contact channels for security incidents. Overall, the security culture is positive but could be enhanced by adopting best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to mitigate common web vulnerabilities.
  2. Add a cookie consent banner and explicit cookie policy to ensure compliance with privacy regulations such as GDPR.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and improve security posture.
  4. Provide clear incident response contact information to enhance transparency and readiness for security events.
  5. Enhance website accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website infrastructure leverages a modern technology stack with asynchronous loading of analytics and marketing scripts to optimize performance. Lazy loading of images and responsive design contribute to good mobile optimization and user experience. The absence of a detected CMS suggests a custom or proprietary platform. Performance is moderate, with potential for improvement by optimizing third-party script usage. Technical debt appears low, but the lack of security headers and cookie consent mechanisms indicates areas for modernization. The site’s SEO is well-implemented with proper meta tags, Open Graph data, and structured JSON-LD markup. Technical risks include potential privacy compliance issues and missing security hardening that could impact business operations if unaddressed.
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.
