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

Heatex is a global manufacturer specializing in plate and rotary heat exchangers primarily used in ventilation and thermal management applications. The company targets industrial clients and professionals in HVAC and manufacturing sectors, positioning itself as a specialized B2B provider with a medium-sized operational scale. The website reflects a professional and consistent brand image with good content quality and clear business focus. Technically, the website is built on WordPress and utilizes common industry tools such as jQuery, Yoast SEO, Cookiebot for consent management, Hotjar for user behavior analytics, and Google Tag Manager. The site is moderately performant with good mobile optimization and basic accessibility features. SEO practices are well implemented with proper meta tags and structured data. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, indicating a good baseline security posture. However, it lacks advanced security headers and publicly available security policies or incident response information. The absence of WHOIS data for the domain raises concerns about domain registration transparency and trustworthiness, which impacts the overall security and business credibility assessment. Overall, the website is professional and functional with good privacy compliance and marketing transparency. Strategic improvements in security headers, contact transparency, and domain registration clarity are recommended to enhance trust 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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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

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

Heatex operates in the manufacturing sector with a focus on heat exchangers for ventilation and thermal management. Its business model is B2B, serving industrial clients and engineering professionals globally. The company leverages digital marketing and analytics tools to optimize user engagement and advertising effectiveness. The website content and structure suggest a stable market position with a clear product offering. However, the lack of visible contact information and domain registration details may hinder customer trust and partnership opportunities. Growth indicators include use of modern analytics and consent management, but further transparency in corporate and security information would strengthen business intelligence.

Security posture

The security maturity of the website is moderate to good. HTTPS is enforced, and cookie consent is managed via Cookiebot, demonstrating compliance with GDPR and privacy regulations. The site uses reputable analytics and marketing tools but lacks advanced HTTP security headers such as Content-Security-Policy and X-Frame-Options. No security.txt or vulnerability disclosure policies are present, and no incident response contacts are visible. The missing WHOIS data for the domain is a significant concern, as it reduces trust in domain legitimacy. Overall, the site shows good baseline security but would benefit from enhanced transparency and additional security controls to mitigate risks and improve compliance.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to reduce attack surface.
  2. Publish a security.txt file and vulnerability disclosure policy to facilitate responsible reporting and improve security posture.
  3. Provide clear and accessible contact information for privacy, security, and general inquiries to enhance trust and compliance.
  4. Improve accessibility features to meet higher standards and broaden user inclusivity.
  5. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to strengthen legitimacy and trust.

Technical notes

Notes

The website is built on WordPress CMS with a tech stack including jQuery, Yoast SEO, Cookiebot, Hotjar, and Google Tag Manager. It uses modern web standards with responsive design and structured data for SEO. Performance is moderate with preconnect hints to external resources. The site lacks some advanced security headers and accessibility enhancements. No hosting provider information was detected. The technical implementation supports business goals but has room for improvement in security and accessibility to reduce technical debt and risks.
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.
