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

Clevero, operated by Poski.com s.r.o., is a professional Czech company specializing in custom e-shop creation and rental services. The company positions itself as a reliable and experienced provider of tailored e-commerce solutions with a focus on security, compliance, and modern features including free updates. Their market presence is supported by strong client testimonials and partnerships with recognized payment and logistics providers. Technically, the website employs modern tracking and analytics tools such as Google Analytics, Facebook Pixel, Hotjar, and reCAPTCHA, indicating a mature digital infrastructure. The site is well-designed, mobile-optimized, and includes comprehensive privacy and cookie policies with consent mechanisms, reflecting good GDPR compliance. However, the absence of WHOIS data and explicit security policies slightly detracts from the overall trustworthiness. Security best practices like HTTPS and form protection are implemented, but additional security headers and incident response information would enhance the security posture. Overall, the website and business demonstrate a high level of professionalism and reliability in the e-commerce sector.

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

  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

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

Clevero operates in the e-commerce sector, targeting businesses seeking custom online store solutions. Their business model includes both bespoke e-shop development and rental with ongoing support and updates. The company leverages partnerships with payment gateways (Comgate, Thepay, GoPay), accounting software (Pohoda), shipping solutions (Balikobot), and live chat support (Smartsupp), creating a comprehensive ecosystem for clients. Testimonials and case studies highlight successful client projects and measurable business growth, indicating effective service delivery and customer satisfaction. The parent company Poski.com s.r.o. provides a stable foundation, and the company maintains active social media channels for marketing and engagement. The website's content quality and navigation support a positive user experience, reinforcing their market position as a trusted e-commerce solutions provider in the Czech Republic.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect forms, demonstrating attention to basic security controls. Cookie consent mechanisms and privacy policies indicate GDPR awareness and compliance. However, no explicit security headers (e.g., Content-Security-Policy, X-Frame-Options) were detected in the provided data, and there is no published security policy or incident response contact information. The absence of WHOIS data raises concerns about domain registration transparency, which is a critical trust factor. No vulnerabilities or exposed sensitive data were observed in the content. Overall, the security posture is good but could be improved by implementing additional HTTP security headers, publishing a security policy, and providing incident response contacts to enhance transparency and readiness.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Investigate and resolve the missing WHOIS data to improve domain registration transparency.
  4. Regularly audit third-party scripts and tracking tools for security and privacy compliance.
  5. Enhance accessibility features to meet higher standards and improve user inclusivity.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Facebook Pixel, Hotjar, and Google reCAPTCHA v2 for analytics, marketing, and security. The presence of slicknav and bxslider scripts suggests use of jQuery-based UI components. The site is mobile-optimized with responsive design and includes structured data (JSON-LD) for SEO and rich snippets. Performance is moderate, with asynchronous loading of scripts to improve page load times. No CMS was explicitly detected, indicating a custom or proprietary platform likely developed by Poski.com. Hosting provider details are not available from the provided data. The site includes comprehensive metadata and Open Graph tags for social media integration. Overall, the technical implementation is solid with room for improvement in security headers and accessibility.
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.
