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

SLOS s.r.o. is a Slovak-based company specializing in LED lighting products and smart lighting control solutions, targeting commercial, residential, municipal, and industrial customers. Established in 2003, the company has a solid market presence supported by partnerships with multiple international lighting brands and memberships in industry organizations. Their website offers a comprehensive product catalog and information about energy-saving lighting solutions, reflecting a B2B business model focused on technology and energy sectors. Technically, the website employs standard web technologies including jQuery and Google Analytics, with a responsive design suitable for mobile devices. However, some modern security headers and policies are missing, which could be improved to enhance security posture.

Overall, the website is professional, trustworthy, and well-structured, with moderate tracking and good business credibility.

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

11 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

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

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 · found on this site
  • 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

The company operates in the energy sector, providing LED lighting and smart control solutions with a focus on energy efficiency and modern lighting technologies such as CASAMBI and DALI. Their market positioning is strengthened by partnerships with well-known lighting manufacturers and industry memberships, indicating a reputable and established presence. The business model is primarily B2B, serving commercial centers, municipalities, residential developers, and industrial clients. The website content and structure support product discovery and customer engagement, with downloadable resources and contact forms facilitating lead generation. The absence of phone contact and physical address on the website may limit direct customer outreach but is partially mitigated by email and web forms. The company appears medium-sized with a stable operational history since 2003.

Security posture

The website uses HTTPS and secure login forms with AJAX, indicating basic security awareness. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No explicit security or incident response policies are published, which is a gap in compliance and transparency. The use of third-party scripts like Google Analytics and Tag Manager introduces moderate tracking but no evident vulnerabilities. No exposed sensitive data or credentials were found in the HTML content. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, publishing security policies, and enhancing incident response readiness.

Recommendations

  1. Implement security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a clear security policy and incident response contact information to improve transparency and compliance.
  3. Add terms of service and vulnerability disclosure policies to enhance legal clarity and security posture.
  4. Consider adding verified company phone numbers and physical address to improve customer trust and contact options.
  5. Regularly audit third-party scripts and update libraries to reduce potential vulnerabilities and improve performance.

Technical notes

Notes

The website is built on a traditional web stack using jQuery and jQuery UI libraries, with Google Analytics and Tag Manager for tracking. The HTML and CSS are well-structured, supporting responsive design and good navigation clarity. No CMS or advanced frameworks were detected, suggesting a custom or lightweight platform. Performance is moderate, with asynchronous loading of analytics scripts. Accessibility features are basic but present. The hosting and registrar information indicate a Slovak hosting provider consistent with the business location. Opportunities exist to modernize the tech stack, improve security headers, and enhance accessibility compliance to reduce technical debt and improve resilience.
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.
