Security score

49/100

Risk levelHigh

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

Thermona, spol. s r.o. is a well-established Czech manufacturer specializing in gas and electric boilers, including cascade boiler systems, with a history dating back to 1990. The company has a strong international presence, exporting to 21 countries and maintaining a medium-sized business profile. Their website reflects a professional and consistent brand image, targeting both residential and commercial heating markets. Technically, the site uses legacy jQuery and common UI libraries, with moderate performance and basic mobile optimization. Security posture is moderate but lacks critical security headers and visible HTTPS enforcement, which should be addressed to enhance trust and compliance. Privacy and cookie policies are absent, representing a compliance gap. Overall, the website is content-rich and trustworthy but would benefit from improved security and privacy practices.

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. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Thermona holds a strong market position as a leading heating equipment manufacturer with a diversified product portfolio including gas, electric, and cascade boilers. Their business model focuses on manufacturing and exporting high-quality heating solutions, supported by a subsidiary in Slovakia. The company leverages product awards and a long operational history as competitive advantages. Their target customers include homeowners and commercial entities seeking efficient heating solutions. The website supports their business with detailed product information and company history, although it lacks direct contact emails and phone numbers, relying on contact forms and social media for communication. The partnership ecosystem includes related domains for spare parts and regional subsidiaries, indicating a well-structured operational network.

Security posture

The website demonstrates a basic security posture with no visible HTTPS enforcement in the HTML content and absence of common security headers such as Content-Security-Policy or X-Frame-Options. Forms are present but lack explicit security or privacy notices. No vulnerability disclosure or incident response information is provided, which limits transparency and preparedness. The lack of privacy and cookie policies also indicates non-compliance with GDPR and related regulations. While no critical vulnerabilities or exposed sensitive data were detected, the site would benefit from implementing modern security best practices to protect user data and enhance trust.

Recommendations

  1. Implement HTTPS site-wide with HSTS to ensure secure communications.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Publish comprehensive privacy and cookie policies to comply with GDPR and inform users.
  4. Establish a vulnerability disclosure policy and incident response contact to improve security transparency.
  5. Enhance mobile optimization and accessibility to improve user experience across devices.

Technical notes

Notes

The website uses an older version of jQuery (1.11.2) alongside FontAwesome and Owl Carousel for UI components. The HTML structure is valid and SEO optimized with appropriate meta tags and Open Graph data. Performance is moderate with some room for improvement in mobile responsiveness and accessibility. No CMS or hosting provider information is evident. The site lacks modern frameworks or platforms, indicating potential technical debt. Improving technology stack modernization and performance optimization could reduce risks and improve user engagement.
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.
