Risk levelHigh

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

Izoglass s.r.o. is a Czech manufacturing company specializing in insulating, processed, interior, and colored glass products, operating since 1999. The company emphasizes its unique in-house modern technology for glass processing, serving both B2B and B2C customers. The website reflects a professional digital presence built on WordPress with a focus on clear product offerings and contact accessibility. Technically, the site uses common industry tools such as Slider Revolution, Contact Form 7 with Google reCAPTCHA, and Google Analytics for tracking. Security posture is adequate with HTTPS and spam protection but lacks advanced security headers and published security policies. Privacy compliance is basic, with no visible cookie consent mechanism, which is a gap for GDPR adherence. Overall, the domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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

9 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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Izoglass holds a stable market position as a specialized glass manufacturer with nearly 25 years of experience. Its competitive advantage lies in proprietary technology for glass processing and a broad product range including insulating, safety, interior, and colored glass, as well as glass cutting services. The business model is direct manufacturing and sales, targeting construction, interior design, and renovation sectors. The company maintains a professional website with clear contact channels but lacks visible certifications or extensive trust signals. The partnership ecosystem includes a digital agency for website development. Growth indicators are moderate with a focus on quality and technology demonstration.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and Google reCAPTCHA protecting the contact form. However, it lacks critical security headers such as Content-Security-Policy and HSTS, which could mitigate common web attacks. There is no visible incident response or vulnerability disclosure policy, which limits transparency and preparedness. The absence of a cookie consent mechanism also indicates partial GDPR compliance. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is functional but could be significantly improved with standard best practices and compliance measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a cookie consent banner/mechanism to comply with GDPR and enhance user privacy transparency.
  4. Regularly update WordPress core, themes, and plugins to mitigate vulnerabilities.
  5. Enhance privacy compliance by detailing data retention policies and user rights.

Technical notes

Notes

The website is built on WordPress using the Avada theme, leveraging popular plugins such as Slider Revolution and Contact Form 7. It uses jQuery and Google services for analytics and spam protection. The site is mobile-optimized with responsive design and good SEO metadata including Open Graph and JSON-LD structured data. Performance is moderate, with no major issues detected but could benefit from optimization. Accessibility is basic, with some screen reader support but no advanced ARIA landmarks or roles detected. Hosting appears to be with Active24, consistent with the registrar information. Overall, the technical infrastructure is solid for a small manufacturing business but could be modernized with enhanced security and privacy features.
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.
