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

Preciosa Group is a globally recognized manufacturer specializing in crystal products, including designer lighting, traditional Czech beads, jewelry, and related machinery. The company leverages a blend of Bohemian tradition and modern technology to serve a diverse audience of B2B and B2C customers worldwide. Their market position is strong, supported by multiple subsidiaries and a presence across continents. Technically, the website is built on a modern Angular framework with good mobile optimization and SEO practices, though some performance optimizations could be considered. Security posture is solid with HTTPS and cookie consent mechanisms in place, but lacks explicit security policies and headers. Overall, the website is professional and trustworthy, though the absence of WHOIS data introduces some uncertainty about domain registration legitimacy.

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

  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.

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

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

Preciosa Group operates in the manufacturing sector with a focus on high-quality crystal products and lighting solutions. Their business model centers on manufacturing and distributing a wide range of crystal-based products and machinery. The company targets both business clients and end consumers interested in premium crystal goods. Their competitive advantage lies in their heritage, craftsmanship, and global footprint. The website reflects a mature digital presence with active social media channels and comprehensive content, supporting brand awareness and customer engagement. The lack of visible direct contact details suggests a preference for controlled communication channels, likely via contact forms.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and cookie consent implemented, indicating GDPR awareness. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies are gaps that could be addressed. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a security.txt file or vulnerability disclosure page limits transparency for security researchers. Overall, the security posture is adequate for a corporate website but could be improved to align with best practices and compliance requirements.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built using Angular 12, leveraging modern web technologies including SVG icons and WebP images for performance optimization. Google Tag Manager is used for analytics and marketing tracking. The site is mobile responsive with good SEO meta tags and Open Graph data. Performance is moderate, with potential for improvement in loading speed and accessibility compliance. No CMS was detected, suggesting a custom or proprietary platform. Hosting provider details are not discernible from the HTML content. Overall, the technical infrastructure supports a professional and scalable web presence but could benefit from enhanced security configurations and performance tuning.
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.
