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

ASIO TECH, spol. s r.o. is a Czech-based manufacturer and service provider specializing in water and air treatment technologies, including wastewater treatment plants for municipalities and family homes, water purification, and air cleaning solutions. Established in 1993, the company has a strong international presence in 32 countries and offers a comprehensive portfolio of products and services focused on sustainability and environmental responsibility. The website is professionally designed, multilingual, and provides detailed information about the company's offerings, references, and educational activities. Technically, the website uses a modern technology stack including jQuery, Fancybox, Rellax, Tiny-slider, and FsLightbox, managed via the Topinfo CMS platform. It integrates Google Tag Manager and Hotjar for analytics and user behavior tracking. The site is mobile-optimized and SEO-friendly but lacks explicit security headers and detailed privacy policies. From a security perspective, the site uses HTTPS and does not expose sensitive data in the HTML. However, the absence of WHOIS data and security headers reduces the overall security posture. No critical vulnerabilities or adult content were detected. Contact information is clearly presented, enhancing business credibility. Overall, the website is trustworthy and professional but would benefit from improved transparency in privacy policies, enhanced security headers, and WHOIS data availability to strengthen domain legitimacy and compliance.

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 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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

ASIO operates in the energy and environmental technology sectors, targeting municipalities, industrial clients, and residential customers. Its competitive advantage lies in its long-standing experience since 1993, international reach, and focus on innovative, sustainable solutions aligned with circular economy principles. The business model combines manufacturing with consulting and educational services, supported by a network of subsidiaries and partners. The company demonstrates strong market positioning with references from notable clients and active participation in industry conferences and educational institutions. Growth indicators include expanding international presence and continuous product innovation.

Security posture

The current security maturity level is moderate. The website employs HTTPS and avoids exposing sensitive data but lacks important security headers such as Content Security Policy and HSTS. No explicit incident response or security policy information is available, and no vulnerability disclosure or security.txt files were found. Tracking technologies are used responsibly, but privacy compliance is minimal due to the absence of a clear privacy policy. The company should enhance its security posture by implementing recommended headers, publishing security policies, and ensuring GDPR compliance to mitigate risks and improve trust.

Recommendations

  1. Publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  2. Implement security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Ensure WHOIS data is properly registered and publicly available to enhance domain legitimacy.
  4. Develop and publish an incident response policy and contact channels for security issues.
  5. Regularly audit and update third-party libraries and tracking scripts to minimize vulnerabilities.

Technical notes

Notes

The website is built on a stable and widely used CMS (Topinfo CMS) with a modern JavaScript technology stack. Performance is moderate with good mobile optimization and SEO practices. The site uses external fonts and media libraries efficiently. However, the lack of detected security headers and incomplete WHOIS data indicate areas for technical improvement. Hosting provider details are not disclosed, which could be relevant for risk assessment. Overall, the technical infrastructure supports the business needs but requires enhancements in security and privacy implementations.
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.
