75/100

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

Proplavani.cz is a Czech Republic-based e-commerce retailer specializing in swimming accessories and sports swimwear, endorsed by Czech Olympian Martina Moravčíková. The business operates primarily online via a Shopify platform with two physical stores in Prague. The website is professionally designed, mobile-optimized, and provides comprehensive privacy and cookie policies compliant with GDPR. The technical infrastructure leverages Shopify's hosting and CDN services, integrating marketing and analytics tools such as Facebook Pixel and AVADA Cookies Bar. Security posture is strong with HTTPS enforced, though some security headers are missing and no explicit security policies or incident response contacts are publicly available. The domain WHOIS data is not publicly accessible, indicating privacy protection, which slightly reduces transparency but is common for e-commerce sites. Overall, the site is trustworthy, well-maintained, and targets general audiences interested in swimming products.

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 targets a niche market of swimming enthusiasts and athletes in the Czech Republic, leveraging the reputation of a national sports figure to build trust and brand recognition. The business model is direct-to-consumer retail via an online Shopify store supplemented by physical retail locations. The presence of multiple marketing and analytics tools suggests active customer engagement and data-driven marketing strategies. The lack of publicly available contact information and WHOIS data suggests a focus on privacy and operational security. The company appears to be a small-sized retailer with a focused product offering and localized market presence.

Security posture

The website employs HTTPS with strong SSL configuration, ensuring encrypted communications. Cookie consent mechanisms and privacy policies indicate compliance with data protection regulations. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options could expose the site to certain web-based attacks. No vulnerabilities or exposed sensitive data were detected in the analysis. The lack of a published security policy or incident response contact reduces transparency and preparedness perception. Overall, the security posture is good but could be improved by implementing additional HTTP security headers and publishing explicit security policies.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Consider providing explicit company contact information to improve business credibility and customer trust.

Technical notes

Notes

The website is built on the Shopify platform, utilizing its CDN and hosting infrastructure, which provides reliable performance and scalability. The tech stack includes modern JavaScript libraries such as Axios and jQuery, and integrates marketing tools like Facebook Pixel and AVADA Cookies Bar for cookie consent management. The site is mobile-optimized and includes SEO-friendly meta tags and Open Graph data for social media sharing. Performance is moderate with deferred and asynchronous loading of scripts to improve page load times. However, some technical debt is noted in the lack of security headers and limited accessibility features. Overall, the technical implementation is solid for an e-commerce retailer but has room for security and accessibility enhancements.
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.
