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

Nupreme.com is an e-commerce retailer specializing in superfoods and dietary supplements, targeting health-conscious consumers primarily in the Czech Republic. The website offers a broad range of products including chlorella, spirulina, young barley, Himalayan salt, mushrooms, maca, vitamins, creams, beverages, collagen, and snacks. The site also provides educational content through a magazine and advice sections, enhancing customer engagement and trust. Technically, the website is built on the Shoptet e-commerce platform, utilizing various modern web technologies such as Google Tag Manager, Google Analytics (GA4), Facebook SDK, and Doofinder for search functionality. The site is mobile-optimized and includes cookie consent mechanisms, indicating compliance with GDPR requirements. However, some technologies like jQuery 1.11.3 are outdated and should be updated to improve security. From a security perspective, the site enforces HTTPS and includes CSRF protection on login forms. While some security headers are not explicitly detected, no critical vulnerabilities or exposed sensitive data were found. The absence of WHOIS registration data raises concerns about domain legitimacy, but the professional website presentation and operational e-commerce functionality suggest legitimate business operations. Overall, the website presents a good security posture and technical maturity for a small retail business, with room for improvement in domain registration transparency and updating legacy libraries. Strategic recommendations include enhancing security headers, updating JavaScript libraries, and publishing explicit security and incident response policies.

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

6 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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, Cloudflare

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

  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

Nupreme.com operates in the niche retail sector of health and wellness, focusing on superfoods and supplements. Its competitive advantage lies in a comprehensive product portfolio and educational content that supports customer decision-making. The business model is direct-to-consumer e-commerce, leveraging digital marketing and analytics tools to optimize customer acquisition and retention. The presence of a magazine and advice sections indicates a content-driven approach to build brand authority. Growth indicators include active product categories and frequent content updates. The partnership ecosystem includes integrations with Google, Facebook, and Doofinder, enhancing marketing and search capabilities. The lack of visible parent or subsidiary companies suggests an independent small business structure.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced site-wide, and login forms include CSRF tokens, reducing risk of common web attacks. Cookie consent mechanisms align with GDPR compliance. However, the use of an outdated jQuery version (1.11.3) poses potential security risks and should be updated. Security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not explicitly present, which could be improved to mitigate clickjacking and MIME sniffing attacks. No incident response or security policy information is publicly available, which limits transparency and preparedness perception. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is adequate for a small e-commerce site but can be enhanced with best practice implementations.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  3. Publish a clear security policy and incident response plan accessible to users to improve transparency and trust.
  4. Ensure WHOIS domain registration data is accurate and publicly available to enhance legitimacy and trustworthiness.
  5. Regularly audit and monitor third-party scripts and integrations to prevent supply chain risks.

Technical notes

Notes

The website is built on the Shoptet e-commerce platform, leveraging a mix of custom and third-party JavaScript libraries including jQuery 1.11.3, Google Tag Manager, Google Analytics GA4, Facebook SDK, and Doofinder search. The site uses asynchronous script loading to optimize performance. CSS and fonts are loaded from CDN sources, improving load times. Mobile optimization is good with responsive design and mobile-specific CSS classes. Accessibility features are basic but present, including skip links and ARIA roles. SEO is supported by proper meta tags, Open Graph tags, and canonical URLs. Performance is moderate, with potential improvements by updating legacy libraries and optimizing third-party scripts. Hosting provider details are not explicitly found. Overall, the technical infrastructure supports a professional e-commerce experience with room for modernization.
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.
