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

The website nanosilver.cz operates as an e-commerce platform specializing in functional clothing embedded with silver molecules, targeting consumers interested in antibacterial and nanotechnology-enhanced apparel. The business appears to be a niche player within the Czech Republic retail sector, offering a range of products including clothing, sprays, and hygiene-related nanoparticle products. The site demonstrates a consistent brand presence with clear contact information and physical store location, supporting its legitimacy. From a technical perspective, the website employs modern JavaScript libraries such as Swiper.js for UI components, Google Tag Manager for analytics, and Facebook Pixel for marketing tracking. The site is mobile-optimized, accessible, and SEO-friendly, with good performance characteristics. However, some improvements could be made in exposing security headers and implementing explicit cookie consent mechanisms to enhance privacy compliance. Security posture is generally strong with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. The absence of a published security policy or incident response contact reduces transparency in security governance. WHOIS data is unavailable, likely due to privacy protection, which slightly impacts trust but is common for small retail businesses. Overall, nanosilver.cz presents a professional and trustworthy online presence with moderate risk. Strategic enhancements in privacy compliance and security transparency would further strengthen its position.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube, Google Ads

      What to do: Document all third-party data sharing in your privacy policy

  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 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

Nanosilver.cz is positioned as a specialized retailer in the functional clothing market, leveraging nanotechnology and silver's antibacterial properties as key differentiators. The business model centers on direct online sales complemented by a physical store in Frýdek-Místek, Czech Republic. The target audience includes health-conscious consumers and those seeking odor-preventing apparel. The company utilizes digital marketing tools and tracking to optimize customer engagement and sales. While the domain registration lacks public WHOIS data, the website's comprehensive product catalog and contact details suggest an established operation. Growth potential lies in expanding product lines and enhancing digital privacy compliance to meet evolving regulatory standards.

Security posture

The website maintains a solid security foundation with HTTPS encryption and integration of trusted analytics and marketing scripts. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. However, the lack of security headers such as Content-Security-Policy and absence of a public security policy or incident response contacts indicate areas for improvement. GDPR compliance is partially addressed through privacy policy presence but lacks explicit cookie consent mechanisms. The overall security maturity is moderate, suitable for a small retail business but with room to enhance transparency and user data protection.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Deploy an explicit cookie consent banner to comply fully with GDPR and enhance user trust.
  3. Publish a clear security policy and incident response contact information to improve transparency and preparedness.
  4. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Regularly review third-party scripts and tracking tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses a modern front-end stack with JavaScript frameworks and libraries such as Swiper.js for interactive sliders and IntersectionObserver API for tracking user engagement. Google Tag Manager and Facebook Pixel are integrated for analytics and marketing purposes. Fonts are loaded from Google Fonts with font-display swap for performance. The site is responsive and includes accessibility features like skip navigation links. Performance is moderate with preconnect hints and lazy loading of images. No CMS or hosting provider is explicitly identified. The technical implementation is solid but could benefit from enhanced security headers and privacy controls.
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.
