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

TOPIN is a Czech-based professional portal specializing in heating technology, providing a wide range of expert articles, company catalogs, calculators, and a magazine subscription service. The website targets professionals and companies in the heating, ventilation, and energy sectors, offering valuable technical content and industry resources. The business model appears to be content-driven with advertising and subscription revenue streams. Technically, the site uses modern web technologies including Bootstrap, jQuery, Google Analytics, and Google Tag Manager, with a responsive design and moderate performance. Security posture is adequate with HTTPS and cookie consent mechanisms, but lacks advanced security headers and explicit security policies. The absence of WHOIS data is a concern for domain legitimacy verification, though the website content and structure suggest a legitimate and established operation. Overall, the site is professional, trustworthy, and safe for general audiences.

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

3 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.

    • 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

  2. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

The portal holds a niche market position in the Czech Republic's heating and energy industry, serving as a key information hub for professionals. Its competitive advantage lies in comprehensive technical content, a detailed company catalog, and interactive tools like calculators. The target customers are industry professionals, installers, and companies seeking technical knowledge and business contacts. Growth indicators include active content updates and partnerships with numerous industry players. The partnership ecosystem is extensive, with many related company domains linked. Strategic observations suggest potential to enhance trust by improving transparency in domain registration and security disclosures.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent mechanism that supports GDPR compliance. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No explicit incident response or vulnerability disclosure information is provided, which could hinder timely security issue reporting. The use of third-party scripts like Google Analytics and Tag Manager introduces some risk, but no vulnerable libraries or exposed sensitive data were detected. Compliance with GDPR is supported by the cookie policy and privacy policy presence. Overall, the security posture is functional but could be improved with enhanced headers, security.txt, and incident response contacts.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Provide explicit contact information for security incidents and data protection officer details.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly audit and update third-party scripts to minimize security risks.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for interactivity, and Google services for analytics and advertising. It uses Evident Web CMS, which supports dynamic content and partial rendering. Performance is moderate with asynchronous loading of scripts and optimized images. SEO is supported by proper meta tags and structured navigation. Mobile optimization is good, with visible responsive menus and search functionality. Accessibility is basic but could be improved. The site integrates Google Maps API and social media links, enhancing user engagement. Technical risks include reliance on multiple third-party scripts and lack of advanced security headers.
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.
