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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

  3. 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

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

Sinclair targets both B2B partners and end consumers in the energy sector, focusing on HVAC and lighting solutions. Their business model includes manufacturing, distribution, and aftersales support, reinforced by technical training and a broad partner network. The company maintains a medium-sized international footprint with a history dating back to 1999. Their competitive advantage lies in product quality, environmental focus, and extensive service offerings. The partnership ecosystem includes related domains such as sinclair-lighting.cz and sinclair-world.com, indicating a diversified but related business portfolio. Growth indicators include active project showcases and participation in international trade fairs.

Security posture

The website enforces HTTPS and implements GDPR-compliant cookie consent with detailed user controls. Forms are protected with CAPTCHA and form protection plugins, reducing spam and abuse risks. However, no explicit security headers like Content-Security-Policy or X-Frame-Options were detected, which could mitigate certain web attacks. The absence of a published security policy or incident response contact limits transparency. No vulnerabilities or exposed sensitive data were identified in the analysis. Overall, the security posture is good but could be improved with enhanced header policies and published security documentation.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to strengthen web security.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.
  4. Enhance domain registration transparency by ensuring WHOIS data is available and accurate.
  5. Continue maintaining GDPR compliance and consider adding a dedicated data protection officer contact.

Technical notes

Notes

The website uses a modern tech stack with Bootstrap for responsive design, jQuery for interactivity, and Google Tag Manager for analytics and marketing. The CMS identified is Pagio, which supports structured content management. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by proper meta tags and multilingual content. Technical debt appears low, but opportunities exist to improve accessibility and security headers. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and functional user experience.
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.
