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

6 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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

hotset operates in the energy sector, focusing on controlled energy flow through heating technology. Its business model centers on manufacturing and engineering customized heating components and systems for industrial clients worldwide. The company leverages its long history and international subsidiaries to maintain competitive advantages. Its marketing and analytics tools indicate a moderate level of user tracking balanced with GDPR compliance. The company actively communicates through social media and maintains a professional online presence. No direct revenue streams or financial data are disclosed, but the extensive product portfolio and engineering services suggest diversified income sources. The partnership ecosystem includes subsidiaries and technology providers, enhancing its market reach.

Security posture

The website employs HTTPS with a good SSL configuration, ensuring secure data transmission. Cookie consent is managed via Borlabs Cookie with granular user controls, supporting GDPR compliance. Tracking includes Google Analytics and Facebook Pixel, with user consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident and should be implemented to enhance protection. There is no visible security policy or incident response information, which could improve transparency and readiness. Overall, the security posture is solid but could benefit from additional hardening and documentation.

Recommendations

  1. Implement comprehensive security headers such as CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and provide incident response contact details.
  3. Add a vulnerability disclosure or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Enhance monitoring and logging to detect and respond to security incidents promptly.

Notes

The website is built on WordPress using the Astra theme and Elementor page builder, supported by multiple plugins for SEO, cookie management, social feeds, and enhanced UI components. The tech stack includes jQuery and modern JavaScript libraries. Performance optimizations such as lazy loading and minified assets are in place, contributing to fast load times. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed with Yoast SEO plugin and structured data (JSON-LD) for rich snippets. Hosting provider details are not explicitly available. The technical infrastructure is modern and well maintained, supporting a professional online presence with minimal technical debt.
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.
