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

SEPOS, spol. s r. o. is a Czech family-owned company specializing in the manufacturing and retail of interior and entrance doors, door frames, and fittings. With over 30 years of experience, the company serves a diverse clientele including investors, architects, construction firms, and end customers. Their business model combines retail and wholesale sales with comprehensive services such as professional advice, certified installation, and delivery. The company maintains a strong market position in the Czech Republic with multiple design stores nationwide. Technically, the website is built on the INT - JET CMS platform and uses modern web technologies including Foundation CSS framework, jQuery, and integrates analytics and marketing tools such as Google Tag Manager, Facebook Pixel, and Snowplow Analytics. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although some accessibility features could be enhanced. From a security perspective, the website enforces HTTPS and implements cookie consent mechanisms compliant with GDPR. However, it lacks a publicly available security policy, incident response contacts, and security.txt file. No critical vulnerabilities or exposed sensitive data were detected. The WHOIS data confirms the domain's legitimacy and long-term registration consistent with the company's stated history. Overall, SEPOS.cz presents a professional and trustworthy online presence with solid business credibility and moderate technical maturity. Strategic improvements in security transparency and accessibility would further strengthen their posture.

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

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 focused on doors and door frames. Their competitive advantage lies in their long-standing market presence, comprehensive service offerings including certified installation, and a broad product range. The business targets multiple customer segments from individual consumers to professional investors and architects. Revenue streams likely include product sales, installation services, and possibly consulting. The company leverages partnerships with suppliers and maintains a network of physical stores across the Czech Republic and Slovakia. Growth indicators include ongoing promotions and active content updates. The website's integration with marketing and analytics tools suggests a data-driven approach to customer engagement.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented, reflecting GDPR compliance. However, the absence of a dedicated security policy, incident response information, and vulnerability disclosure mechanisms indicates gaps in security transparency and readiness. No security headers were detected in the provided data, which could be improved to mitigate common web threats. The use of reputable third-party analytics and marketing scripts is balanced with privacy considerations via consent banners. Overall, the security posture is adequate for the business type but could benefit from enhanced policies and technical controls.

Recommendations

  1. Publish a clear and accessible security policy outlining security practices and commitments.
  2. Provide incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Add standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Enhance website accessibility features to improve compliance with WCAG standards and user experience.

Technical notes

Notes

The website is built on a proprietary CMS (INT - JET 4.01) and uses the Foundation CSS framework for responsive design. It integrates multiple third-party scripts for analytics (Google Tag Manager, Snowplow), marketing (Facebook Pixel), and cookie management (Cookie Script). Hosting leverages AWS Cloudfront CDN for content delivery. Performance is moderate with lazy loading images and asynchronous script loading. SEO is supported by proper meta tags and structured navigation. Some technical debt may exist due to legacy CMS usage and minor accessibility limitations. Modernization opportunities include updating security headers, improving accessibility, and streamlining third-party script usage to optimize performance and privacy.
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.
