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

SIKO KOUPELNY A KUCHYNĚ is a leading Czech retailer specializing in stylish bathroom and kitchen solutions, offering a wide range of quality products, project planning, and turnkey realization services. The company targets general consumers primarily in the Czech Republic and neighboring countries, positioning itself as a market leader in home improvement retail. The website reflects a professional and consistent brand image with good content quality and user experience. Technically, the site is built on a modern Angular framework integrated with SAP Commerce Cloud, leveraging multiple marketing and analytics tools with user consent mechanisms. Security posture is strong with HTTPS enforcement and security headers, though the absence of a public security policy and incident response information is noted. The lack of WHOIS data reduces domain trust slightly but does not detract significantly from the overall legitimacy. Strategic recommendations include publishing security policies, enhancing incident response transparency, and verifying domain registration details to improve trust. Overall, SIKO demonstrates a mature digital presence with room for security and compliance enhancements.

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

9 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

    • High

      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

    • 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. 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"

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

SIKO operates a large-scale retail business focused on bathrooms, kitchens, floors, and doors, combining product sales with project planning and turnkey realization. Its market positioning as a leading Czech retailer is supported by a comprehensive product offering and physical store presence alongside online sales. The business model integrates e-commerce with offline services, targeting homeowners and renovators. The company employs advanced marketing tools such as Exponea and Google Tag Manager to optimize customer engagement and retargeting. Growth indicators include active promotions and a multi-country API infrastructure. Partnerships with service providers like Daktela and Coworkers AI chatbot enhance customer support. The company maintains a consistent brand and professional content, supporting strong business credibility.

Security posture

The website enforces HTTPS and implements key security headers including Content Security Policy, X-Frame-Options, and Strict-Transport-Security, reflecting a good security baseline. Cookie consent mechanisms comply with GDPR requirements, and no exposed sensitive data or vulnerable libraries were detected. However, the absence of a dedicated security policy page and incident response contact reduces transparency and may impact incident handling readiness. No vulnerability disclosure or security.txt file is present, limiting external reporting channels. The WHOIS data absence raises concerns about domain registration transparency. Overall, the security posture is solid but could benefit from enhanced policy disclosures and incident response readiness to align with best practices and regulatory expectations.

Recommendations

  1. Publish a comprehensive security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information and establish a vulnerability disclosure process.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance security headers with additional directives such as Feature-Policy or Permissions-Policy if applicable.
  5. Verify and update WHOIS domain registration information to improve domain trust and legitimacy.

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.
