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

Customize.cz, s.r.o. is a Czech-based company specializing in personalization solutions for e-commerce websites. Their core offering is personalized recommendation boxes that help online shops increase sales and customer satisfaction by analyzing user behavior in real-time and dynamically presenting relevant products. The company operates on a commission-based business model tied to conversion orders, positioning itself as a niche player in the Czech and Slovak e-commerce personalization market. The website is professionally designed, mobile-optimized, and provides clear contact channels and customer testimonials, supporting a trustworthy business image. Technically, the website uses a modern front-end stack including Bootstrap, jQuery, and popular UI libraries like Swiper and Owl Carousel. Google Analytics and a third-party chat service (Suppoo) are integrated for marketing and customer engagement. While the site uses HTTPS and implements a cookie consent banner with detailed user controls, it lacks visible advanced security headers and formal security or incident response policies. The site is accessible without WAF or blocking mechanisms, indicating good availability. From a security perspective, the site demonstrates basic compliance with GDPR through cookie consent and privacy policy pages but lacks explicit terms of service, security policy, or vulnerability disclosure mechanisms. No critical vulnerabilities or suspicious content were detected. The WHOIS data aligns well with the business claims, showing a domain age consistent with the company's founding date and no privacy protection, enhancing trustworthiness. Overall, Customize.cz presents a solid, professional online presence with moderate technical maturity and basic security posture. Strategic improvements in security headers, formal policies, and enhanced privacy compliance could elevate their security and trust profile further.

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 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

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

Customize.cz operates in the e-commerce personalization sector, targeting online retailers seeking to increase average order value and customer satisfaction through tailored product recommendations. Their competitive advantage lies in real-time user behavior analysis and algorithm-driven product selection, reducing manual workload for e-shop operators. The commission-based pricing model aligns incentives with client success, fostering long-term partnerships. The company has established references with notable Czech and Slovak e-shops, indicating market acceptance and operational experience. The absence of phone contact but presence of email and contact form suggests a lean support model. The company is small-sized, founded in 2013, and focused on the Czech market, with no visible subsidiaries or parent companies. Their marketing ecosystem includes Google Analytics and chat support, but no evident affiliate or retargeting programs. The business model is scalable and technology-driven, with potential for growth in regional markets.

Security posture

The website employs HTTPS, ensuring encrypted communications, and implements a cookie consent mechanism supporting GDPR compliance. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No visible security or incident response policies are published, and no vulnerability disclosure or security.txt files are present, limiting transparency for security researchers. The contact form includes basic validation but lacks visible anti-CSRF protections. Third-party scripts like Google Analytics and Suppoo Chat introduce potential privacy and security risks if not regularly audited. Overall, the security posture is basic but functional, with room for improvement in formal policies, header implementation, and third-party risk management.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish formal security and incident response policies accessible from the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance contact form security with anti-CSRF tokens and server-side validation.
  5. Regularly audit third-party scripts and minimize tracking to improve privacy compliance.

Technical notes

Notes

The website uses a standard front-end technology stack with Bootstrap for responsive design, jQuery for DOM manipulation, and UI libraries such as Swiper and Owl Carousel for interactive elements. Google Analytics is integrated for visitor tracking, and a third-party chat widget (Suppoo) provides customer support functionality. The site is mobile-optimized and SEO-friendly with appropriate meta tags and structured navigation. Performance is moderate, with no explicit indicators of slow loading but some reliance on multiple external scripts. No CMS or hosting provider information is detected. The site lacks advanced accessibility features but meets basic standards. Technical debt appears low, but security header omissions and lack of formal policies represent modernization opportunities to reduce risk and improve compliance.
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.
