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

KERACLAY, a.s. is a Czech Republic-based manufacturer specializing in clays and ceramic materials, serving both professional industrial processors and amateur ceramic creators. The company emphasizes sustainable production and environmental care, with a product portfolio including clays, ceramic masses, chamotte masses, and sandstone aggregates. The website reflects a medium-sized enterprise with a history dating back to 2012 and roots extending to 1975, with annual revenues exceeding 130 million CZK. The business model focuses on manufacturing and direct sales, positioning KERACLAY as a reputable regional player in the manufacturing sector. Technically, the website employs jQuery 1.11.3 and Swiper.js for UI components, with a responsive design optimized for mobile devices. The site demonstrates good content quality, clear navigation, and professional branding consistency. However, the technical stack includes an outdated jQuery version, and no CMS or hosting provider information is evident. Performance is moderate, and accessibility is basic. From a security perspective, the site uses HTTPS but lacks visible security headers and explicit privacy or cookie policies, which impacts privacy compliance. No incident response or vulnerability disclosure information is present. The WHOIS data is unavailable, limiting domain trust assessment and raising concerns about registration transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the website is professional and trustworthy in content and business representation but would benefit from improved privacy compliance, updated technical components, and enhanced security practices. The absence of WHOIS data is a notable gap that should be addressed to improve domain legitimacy 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

7 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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

KERACLAY operates in the manufacturing sector with a focus on ceramic materials and clays. The company leverages a business model centered on production and direct sales, targeting industrial clients and hobbyists. Its competitive advantage lies in its long-standing tradition, product quality, and commitment to sustainability and environmental responsibility. Revenue streams are primarily from product sales, with growth indicators including recent installation of photovoltaic systems and increasing annual revenues. The partnership ecosystem includes related companies Keramost and Kerain, indicating a collaborative industrial network. Strategic observations highlight the company's focus on innovation, environmental care, and market presence in the Czech Republic region.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled but lacks critical security headers such as Content Security Policy, HSTS, and X-Frame-Options. The use of an outdated jQuery version poses potential vulnerabilities. There is no visible privacy policy or cookie consent mechanism, indicating compliance gaps with GDPR and related regulations. Incident response readiness and vulnerability disclosure mechanisms are absent, limiting the organization's ability to manage security incidents effectively. No exposed sensitive data or known vulnerabilities were detected in the HTML content. Overall, the security posture is functional but requires enhancements to meet modern standards and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  3. Add and configure security headers such as Content Security Policy, HSTS, and X-Frame-Options to strengthen site security.
  4. Establish and publish incident response and vulnerability disclosure policies to improve security transparency and readiness.
  5. Conduct a WHOIS domain registration audit to verify domain legitimacy and update registration information as needed.

Technical notes

Notes

The website uses a relatively simple technology stack with jQuery 1.11.3 and Swiper.js for interactive elements. The HTML structure is valid and includes proper meta tags for SEO and mobile responsiveness. Performance is moderate, with lazy loading of images and responsive design elements. Accessibility features are basic, with room for improvement in ARIA roles and keyboard navigation. No CMS or hosting provider information is evident, suggesting a custom or static site deployment. The site lacks advanced analytics or tracking scripts, indicating minimal user tracking. Technical risks include the use of outdated JavaScript libraries and missing security headers, which could impact security and user trust.
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.
