Risk levelLow

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

Preciosa Group is a well-established manufacturer specializing in crystals, fine jewelry stones, designer lighting, traditional Czech beads and glass, and related machinery and packaging solutions. The company operates globally with a presence on six continents and serves a B2B audience in various manufacturing and decorative sectors. The website reflects a professional and consistent brand image with comprehensive content about their divisions and products. Technically, the site uses modern web technologies including Angular framework and Google Tag Manager for analytics, with good mobile optimization and SEO practices. Security posture is solid with HTTPS and cookie consent mechanisms, though explicit security policies and incident response contacts are absent. The missing WHOIS data is a concern for domain legitimacy but the overall digital footprint suggests a credible business. Strategic recommendations include enhancing security headers, publishing security policies, and improving contact 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

  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 holds a strong market position as a leading European manufacturer of crystal and glass products with diversified subsidiaries focusing on lighting, components, jewelry, and machinery. Their business model centers on manufacturing and global distribution, targeting industrial and design sectors. The company leverages traditional craftsmanship combined with modern technology, appealing to B2B customers worldwide. Their digital presence supports brand trust with detailed product and company information, social media engagement, and compliance documentation. Growth indicators include multiple production sites and extensive global reach. The partnership ecosystem includes subsidiaries like Preciosa Components and Vinolok, reinforcing vertical integration.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent compliance, and no visible exposure of sensitive data. However, the absence of security headers such as CSP, HSTS, and X-Frame-Options, as well as lack of explicit security or incident response policies, indicates room for improvement. No vulnerability disclosures or security.txt files were found, which could enhance transparency and trust. The use of third-party scripts like Google Tag Manager requires ongoing monitoring to mitigate supply chain risks. Overall, the security maturity is good but could be elevated by formalizing policies and improving header configurations.

Recommendations

  1. Implement comprehensive HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Conduct regular audits of third-party scripts and dependencies to identify and mitigate vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on Angular 12.2.15, indicating a modern single-page application framework. It uses Google Tag Manager for analytics and tracking, and serves optimized images including WebP format for performance. The site is responsive and mobile-optimized with good SEO meta tags and Open Graph data. However, no CMS or hosting provider information was detected. Performance is moderate, with potential improvements in accessibility and security header implementation. The technical infrastructure supports a professional corporate presence but could benefit from enhanced security and accessibility best practices.
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.
