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

CloudSailor s.r.o. operates a Czech-language e-commerce platform solution aimed at enabling businesses to efficiently manage and operate online shops. The company positions itself as a provider of smart, intuitive, and modern tools with features such as product administration, integration with external systems, personalization, pricing management, and advanced search capabilities. The website demonstrates a professional design with clear navigation and references to notable clients, indicating a stable market presence in the Czech Republic's technology and e-commerce sectors. Technically, the site employs common analytics and marketing tools including Google Analytics, Facebook Pixel, and Leady tracking, and uses jQuery and Owl Carousel for UI components. While HTTPS is used, no explicit security headers were detected in the HTML content, and no privacy or cookie policies were found, indicating room for improvement in compliance and security transparency. The absence of WHOIS registrant data is due to EURid privacy policies, but the domain and website content appear consistent and legitimate. Overall, the site is functional and professional but could enhance its security posture and privacy compliance.

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"

      • 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';…

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

CloudSailor targets e-commerce businesses seeking comprehensive management solutions, leveraging partnerships with accounting software and personalization service providers to enhance its offering. The business model is B2B SaaS with a focus on automation and customer experience improvements. The company maintains a moderate market position with references to established clients and membership in a relevant industry association. Revenue streams likely include software licensing or subscription fees. The website content and marketing emphasize ease of use, integration capabilities, and personalization, which are competitive advantages. Growth potential exists through expanding integrations and improving compliance and security features. The partnership ecosystem includes Flexibee and Recombee, which strengthens the platform's value proposition.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and no visible exposure of sensitive data. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. The use of third-party tracking scripts introduces privacy considerations, and no explicit privacy or cookie policies were found to inform users or obtain consent, which is a compliance gap under GDPR. No incident response or vulnerability disclosure information is provided, limiting transparency and readiness signals. The security score is moderate, reflecting a need for improved security best practices and compliance measures to reduce risk and enhance trust.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to improve GDPR compliance.
  2. Add and configure security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen web security.
  3. Publish incident response and vulnerability disclosure policies with dedicated contact channels to enhance transparency and readiness.
  4. Regularly update all JavaScript libraries and dependencies to mitigate vulnerabilities.
  5. Include clear and accessible company contact information on the website to improve business credibility and user trust.

Technical notes

Notes

The website uses a mix of modern and legacy technologies, including jQuery 1.12.4, Owl Carousel, Google Analytics, Facebook Pixel, and Google Maps API. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with asynchronous loading of tracking scripts to reduce blocking. No CMS or hosting provider information was detected. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. The site could benefit from modernization of JavaScript libraries and implementation of security best practices to reduce technical risks.
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.
