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

Frisör Klier správní s.r.o. operates the largest network of hair salons in the Czech Republic, catering to both men and women with professional hairdressing services and premium hair care products. The company maintains a strong market position as a leading retail service provider in the hair care industry, supported by an e-commerce platform for product sales. Their website reflects a professional and consistent brand image, targeting a broad audience seeking quality hair care solutions. Technically, the site employs modern web technologies including Google Tag Manager, Google Analytics, Facebook Pixel, and the Nette Framework, ensuring a robust digital presence with moderate performance and good mobile optimization. Privacy compliance is well addressed with a comprehensive privacy policy and an active cookie consent mechanism, demonstrating adherence to GDPR requirements. However, the absence of WHOIS registration data and visible security headers slightly detracts from the overall trustworthiness. No direct contact phone numbers or physical addresses were found on the homepage, though a professional contact email is provided. Overall, the website is secure, user-friendly, and business credible, with room for improvement in transparency and security hardening.

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

4 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.

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 leverages a retail business model focused on hairdressing services and product sales through physical salons and an online shop. Their competitive advantage lies in their extensive salon network and premium product offerings. The target customer segment includes men and women across the Czech Republic seeking professional hair care. The website's integration with major advertising and analytics platforms indicates a mature marketing strategy. The lack of WHOIS data and limited direct contact information suggests a potential area for enhanced corporate transparency. The company appears to maintain a solid partnership ecosystem with social media platforms and advertising networks, supporting growth and customer engagement.

Security posture

The website demonstrates a moderate security posture with HTTPS usage and a cookie consent mechanism in place. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap. No vulnerabilities or exposed sensitive data were detected in the provided content. The use of third-party scripts like Google Analytics and Facebook Pixel is standard but requires ongoing monitoring for security risks. Incident response and security policy information are not publicly available, indicating an opportunity to improve transparency and readiness. Overall, the security maturity is adequate but could benefit from enhanced header implementation and visible security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish clear security and incident response policies on the website to improve transparency and user trust.
  3. Verify and publish WHOIS domain registration details to enhance legitimacy and reduce suspicion.
  4. Add clear and accessible contact information including phone numbers and physical addresses to improve business credibility.
  5. Regularly audit third-party scripts and dependencies to prevent vulnerabilities and ensure compliance with privacy regulations.

Technical notes

Notes

The website is built using the Nette Framework and integrates several modern technologies such as Google Tag Manager, Google Analytics (including GA4), Facebook Pixel, and Slick Carousel for UI components. The site uses a cookie consent management platform (CookieScript) to comply with privacy laws. Performance is moderate with responsive design and mobile optimization evident. SEO is supported by proper meta tags and structured content. However, no CMS was explicitly detected, and hosting provider details are not available. The absence of security headers and WHOIS data indicates areas for technical improvement. Overall, the technical infrastructure supports a professional online presence but could be enhanced with better 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.
