Risk levelLow

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

Purmo is a leading supplier specializing in sustainable indoor climate comfort solutions, offering a broad range of heating and cooling systems including hydronic radiators, electric heating devices, and underfloor heating systems. The company targets stakeholders and customers seeking efficient and comfortable climate control solutions. The website reflects a mature digital presence with a well-structured product catalog and consistent branding. Technically, the site uses modern frameworks such as Bootstrap 4 and integrates Google Tag Manager and Cookiebot for analytics and cookie consent management. Security posture is adequate with HTTPS enforced and cookie consent implemented; however, the absence of explicit security headers and privacy policy pages indicates room for improvement. The WHOIS data for the subdomain global.purmo.com is not available, which is typical for subdomains, and the main domain purmo.com is presumably the registered entity. Overall, the website is professional and trustworthy but would benefit from enhanced transparency in privacy and security policies.

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

1 finding 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 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

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

Purmo operates in the energy sector focusing on heating and cooling solutions, positioning itself as a market leader in sustainable indoor climate comfort. Its business model revolves around manufacturing and supplying a wide range of climate control products and accessories. The detailed product hierarchy and extensive catalog suggest a strong B2B and B2C presence. The use of multiple language alternate links indicates a global market reach. The company leverages digital marketing tools and analytics to optimize user engagement. Lack of visible contact details and privacy documentation may affect customer trust and compliance in some jurisdictions.

Security posture

The website enforces HTTPS, uses cookie consent mechanisms, and integrates Google Tag Manager for analytics, reflecting a baseline security maturity. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which could hinder timely reporting and mitigation of security issues. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Overall, the security posture is moderate but could be significantly improved by adopting best practices and transparency measures.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to enhance transparency and compliance.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options) to strengthen security posture.
  3. Provide clear contact information including security incident response contacts and data protection officer details.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features and conduct regular security audits to maintain and improve website security and user experience.

Technical notes

Notes

The website is built using Bootstrap 4, with CSS and JavaScript assets optimized and minified. It uses Google Tag Manager for analytics and Cookiebot for cookie consent management, indicating a modern approach to user tracking and privacy compliance. The site is mobile responsive with good navigation clarity and SEO optimization. No CMS or hosting provider information was detected from the provided content. Performance is moderate, with potential for improvement by optimizing resource loading and accessibility. The technical infrastructure supports a professional e-commerce or product catalog platform but lacks some advanced security and compliance features.
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.
