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

ISOTRA a.s. is a well-established Czech manufacturer specializing in high-quality interior and exterior shading solutions including jalousies, rollos, pergolas, and insect screens. With over 20 years of market presence and a strong export footprint to nearly 50 countries, the company positions itself as a technological leader in its industry. Their business model focuses on custom-made products serving both B2B and end customers, supported by in-house component manufacturing and tooling capabilities. The website reflects a professional and comprehensive digital presence with clear branding and extensive product information. Technically, the website employs modern JavaScript libraries such as jQuery, Modernizr, and Slick Slider, alongside Google Analytics and Tag Manager for tracking. The site is hosted on Active24, a reputable Czech hosting provider, and demonstrates good mobile optimization and accessibility features. SEO practices are well implemented with proper meta tags and structured data. However, some security headers are missing, and there is no explicit incident response or vulnerability disclosure information. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected. The absence of a terms of service page and security policy reduces completeness but does not significantly impact trust. WHOIS data is limited but consistent with the company’s Czech location and hosting setup. Overall, ISOTRA’s website is professional, secure, and compliant with privacy regulations, supporting its strong market position. Strategic improvements in security headers and transparency around incident response would further enhance trust and resilience.

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

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

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

ISOTRA operates in the manufacturing sector, focusing on shading technology products with a strong emphasis on quality and innovation. The company leverages its own tooling and component production to maintain control over product quality and differentiation. Its market positioning as a technological leader in the Czech Republic and internationally is supported by certifications and a broad product portfolio. The business targets both professional clients and private customers, offering tailored solutions. The company’s digital ecosystem includes related domains for tooling and powder coating services, indicating vertical integration. Growth indicators include active participation in trade fairs and continuous product innovation. The partnership ecosystem is visible through related domains and social media engagement, enhancing brand reach and customer interaction.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and a GDPR-compliant cookie consent mechanism. The site disables right-click context menus to reduce casual content copying. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement in defense-in-depth. No incident response or abuse contact information is provided, which is a gap in security transparency. No vulnerabilities or exposed sensitive data were found in the HTML content. The use of reputable third-party analytics and tag management services is noted, with moderate user tracking levels balanced by privacy controls. Overall, the security posture is good but could be enhanced by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and trust.
  3. Add a terms of service page to clarify user rights and obligations.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance privacy compliance by detailing data retention policies and providing users with granular cookie management options.

Technical notes

Notes

The website uses a modern and stable technology stack with jQuery, Modernizr, Slick Slider, and PhotoSwipe for UI/UX enhancements. Google Analytics and Tag Manager are integrated for analytics and marketing purposes. The site is hosted on Active24, a known Czech hosting provider, ensuring reliable infrastructure. Performance is moderate with good mobile responsiveness and accessibility features. SEO is well addressed with proper meta tags, canonical links, and structured data (JSON-LD) describing the organization. The site disables right-click context menus as a minor content protection measure. No CMS is explicitly detected, suggesting a custom or proprietary platform. Technical debt appears low, but security header implementation is a notable gap. Overall, the technical infrastructure supports a professional and user-friendly experience.
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.
