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

Sedláček s.r.o. operates the website www.sedlacek-karcher.cz as an authorized reseller and service provider of cleaning and hygiene systems, prominently featuring brands such as Kärcher, TORK, and Kimberly-Clark. The company has a long-standing presence since 1994, targeting both business and consumer markets with sales, service, and rental offerings. The website is professionally designed with good navigation and mobile optimization, supporting a positive user experience. Technically, the site employs modern tracking and analytics tools including Google Tag Manager, Hotjar, and Facebook Pixel, alongside security measures like HTTPS and Google reCAPTCHA for form protection. However, the absence of explicit privacy and cookie policy pages and lack of WHOIS domain registration data introduce some trust and compliance concerns. Overall, the site demonstrates a moderate security posture with room for improvement in transparency and security headers.

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

    • 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

  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

      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

The company positions itself as a niche retailer and service provider in the cleaning and hygiene sector within the Czech Republic. Its business model combines product sales, equipment rental, and maintenance services, leveraging partnerships with well-known brands to enhance market credibility. The target audience includes both commercial clients and end consumers seeking cleaning solutions. The website's content and structure support effective product discovery and customer engagement, although the lack of visible email contacts and detailed company registration data may limit some trust signals. The partnership ecosystem includes official brand sites, reinforcing legitimacy. Growth potential could be enhanced by improving compliance documentation and expanding contact channels.

Security posture

The website enforces HTTPS and integrates anti-bot measures via Google reCAPTCHA, indicating a baseline security awareness. Tracking scripts and marketing pixels are present, suggesting moderate user data collection practices. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response information is provided, which could hinder timely security issue reporting and resolution. The missing privacy and cookie policies also represent compliance gaps under GDPR. No obvious vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but would benefit from enhanced header implementation and transparency.

Recommendations

  1. Publish comprehensive privacy and cookie policy pages to improve GDPR compliance and user trust.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear incident response and vulnerability disclosure contacts or a security.txt file.
  4. Verify and update WHOIS domain registration information to enhance domain legitimacy and trust.
  5. Expand visible contact information to include verified company emails for customer and security communications.

Technical notes

Notes

The website uses a modern technology stack with integration of multiple third-party analytics and marketing tools such as Google Tag Manager, Hotjar, and Facebook Pixel. Fonts are loaded via Adobe Typekit. The site appears to be custom-built or uses a proprietary CMS, with no explicit CMS detected. Performance is moderate with preloading of key images and lazy loading techniques. Mobile optimization is good, and SEO meta tags are properly configured. Accessibility features are basic but present. Hosting provider details are not disclosed. Technical debt is not evident from the HTML snapshot, but the lack of some security headers suggests room for modernization in security practices.
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.
