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

4 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  2. 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

  3. 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 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';…

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

Thermon's market positioning is strong, supported by ISO certifications and a longstanding domain registration. The company leverages extensive analytics and marketing tools to optimize user engagement and lead generation. Their business model focuses on manufacturing and supplying specialized heating products and services to industrial clients. The presence of multiple RFQ forms and detailed product information indicates a focus on direct sales and customer support. The company maintains a professional online presence with clear contact channels and compliance with privacy regulations.

Security posture

The website enforces HTTPS and uses clientTransferProhibited domain status, enhancing domain security. However, DNSSEC is not enabled, representing a minor security gap. The site uses CAPTCHA on forms and cookie consent mechanisms, indicating attention to security and privacy. There is no explicit security policy or incident response information publicly available, and no vulnerability disclosure or security.txt file was found. Security headers are partially implemented but could be improved with Content-Security-Policy and Referrer-Policy headers. Overall, the security posture is good but could benefit from enhancements in transparency and DNS security.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Implement additional security headers such as Content-Security-Policy and Referrer-Policy.
  4. Establish and publicize a vulnerability disclosure program or security.txt file.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built on WordPress CMS using modern technologies including jQuery, Bootstrap, FontAwesome, and multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, Hotjar, Mouseflow, and Visual Website Optimizer. The site is mobile optimized with good SEO practices and accessibility features at a basic level. Performance is moderate, with room for improvement in loading speed and technical optimization. The extensive use of third-party scripts increases tracking capabilities but also the attack surface, necessitating regular security reviews.
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.
