SEPOS, spol. s r. o. is a Czech family-owned company specializing in the manufacturing and retail sale of interior and exterior doors, door frames, and related hardware. With over thirty years of experience, the company offers a comprehensive service including professional advice and certified installation, targeting investors, architects, construction firms, and end customers. The website reflects a well-established business with a clear market position as a specialist in doors and frames within the Czech Republic. Technically, the website employs modern web technologies including the Foundation framework, jQuery, and integrates multiple tracking and advertising tools such as Google Tag Manager, Facebook Pixel, and Adform, while providing a cookie consent mechanism to comply with GDPR requirements. Security-wise, the site uses HTTPS and has basic security practices but lacks explicit security headers and incident response contact information, which could be improved.

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

10 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

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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

SEPOS operates in the retail and manufacturing sectors, focusing on doors and door frames. Its business model combines wholesale and retail sales with value-added services such as consultation and certified installation. The company targets a diverse customer base including investors, architects, construction companies, and individual consumers. The website indicates a medium-sized enterprise with a strong regional presence in the Czech Republic and Slovakia. The company maintains active social media channels on Facebook, Instagram, and Pinterest, enhancing its brand visibility. The presence of certifications and a professional service offering are trust signals that support its market position. However, the lack of publicly available WHOIS data and domain registration details is a gap that should be addressed to strengthen credibility further.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and a cookie consent mechanism in place, indicating awareness of privacy and security compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for improvement in mitigating common web vulnerabilities. No explicit security policies or incident response contacts are provided, which limits transparency and preparedness for security incidents. The use of multiple third-party tracking and advertising scripts increases the attack surface and necessitates vigilant monitoring. Overall, while no critical vulnerabilities were detected, enhancing security headers and providing clear incident response information would improve the security maturity of the site.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security policy and provide clear incident response contact information to improve transparency and readiness.
  3. Verify and publish accurate WHOIS domain registration data to increase trust and legitimacy.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks and potential vulnerabilities.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance and security posture.

  4. Business information is clearly presented with contact details and social media presence.

Technical notes

Notes

The website is built on the INT - JET 4.01 CMS platform and uses the Foundation front-end framework along with jQuery for interactivity. It integrates multiple analytics and advertising technologies including Google Tag Manager, Facebook Pixel, Adform, and Snowplow Analytics, supported by a cookie consent mechanism to comply with GDPR. The site is mobile-optimized with responsive design and good SEO practices including meta tags and structured navigation. Performance is moderate, with lazy loading images and asynchronous script loading. However, the lack of explicit security headers and incomplete WHOIS data represent technical risks that could impact business operations and trust. Hosting provider details are not explicitly identified. Overall, the technical infrastructure is modern but could benefit from enhanced security configurations and transparency.
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.
