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

TIAMI is a Czech-based luxury jewelry brand specializing in lab-grown diamonds, offering a sustainable and high-quality alternative to mined diamonds. The company operates primarily through an e-commerce platform supported by a showroom in Prague, targeting consumers who value sustainability and craftsmanship. The website is professionally designed, mobile-optimized, and provides a seamless user experience with clear navigation and rich content about the brand and products. Technically, the site leverages modern web technologies and integrates multiple marketing and analytics tools while maintaining good security practices such as HTTPS and security headers. However, the absence of publicly available WHOIS data due to privacy protection is noted but does not detract from the site's legitimacy given the strong trust signals and certifications present. Privacy compliance is well addressed with clear cookie consent mechanisms and a comprehensive privacy policy. Overall, TIAMI presents a credible and trustworthy online presence in the luxury retail sector.

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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

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

TIAMI occupies a niche market segment focusing on lab-grown diamond jewelry, which appeals to environmentally conscious consumers seeking luxury products. The business model combines direct online sales with personalized customer service, including custom manufacturing and showroom consultations. The company benefits from strong customer satisfaction as evidenced by numerous positive reviews and certifications such as IGI certificates and cooperation with the Czech hallmarking office. Marketing efforts are diversified across multiple digital channels including Google, TikTok, Facebook, and LinkedIn, supported by email marketing and retargeting tools. The brand's emphasis on sustainability and quality craftsmanship positions it well against traditional jewelers, with growth potential in the expanding lab-grown diamond market.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of security headers, and CSRF protection on forms. Cookie consent is actively managed, aligning with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the site lacks publicly disclosed security policies or incident response contacts, which could enhance transparency and preparedness. The integration of multiple third-party scripts necessitates ongoing vigilance to mitigate supply chain risks. Overall, the security measures are robust for an e-commerce platform, but formal documentation and vulnerability disclosure policies would strengthen the security culture.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user data protection.
  2. Provide clear incident response contact information to facilitate reporting of security issues.
  3. Implement and publicize a vulnerability disclosure or bug bounty program to encourage responsible reporting.
  4. Enhance website accessibility to meet higher standards for users with disabilities.
  5. Regularly review and update third-party scripts and dependencies to minimize security risks.

Technical notes

Notes

The website is built on the Shoptet e-commerce platform, utilizing jQuery and various marketing and analytics integrations such as Google Tag Manager, TikTok Pixel, Facebook SDK, and LinkedIn Insight Tag. The site is mobile-optimized with responsive design and includes accessibility features, though these could be improved. Performance is moderate, with efficient use of CDN resources for static content. SEO is supported by proper meta tags and Open Graph data. The technical infrastructure is solid for a small to medium-sized retail business, but opportunities exist to modernize JavaScript usage and enhance accessibility compliance.
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.
