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

Terezia.eu is an e-commerce website specializing in dietary supplements derived from medicinal mushrooms and plants. The site targets a general audience interested in health and natural supplements, offering products primarily in the Czech market with alternate language support for English and Slovak. The business appears to be small-sized with a focused product offering. Technically, the website employs modern web technologies including Google Tag Manager, Cookiebot for cookie consent management, and integrates multiple analytics and advertising platforms such as Google Analytics, Microsoft Clarity, Hotjar, and Meta Platforms. The site is accessible over HTTPS and implements a comprehensive cookie consent mechanism, reflecting a good level of privacy compliance. However, the absence of explicit privacy policy and terms of service pages, as well as lack of visible company contact information, limits full transparency and business credibility. Security posture is moderate with no visible security headers and no exposed vulnerabilities detected in the provided data. Overall, the website is professionally designed with good user experience and moderate SEO and accessibility features.

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

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

  • 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 website operates in the health supplement sector, focusing on natural products from medicinal mushrooms and plants. It leverages a multi-language approach to reach Czech, Slovak, and English-speaking customers. The business model is e-commerce retail, likely direct-to-consumer. The presence of multiple advertising and tracking partners indicates an active marketing strategy aimed at personalized advertising and retargeting. The lack of detailed company information and contact details suggests a smaller or privacy-conscious operation. The partnership with related domains like terezia.sk supports regional market expansion. The company uses third-party services for analytics and marketing, indicating reliance on established platforms for customer insights and engagement.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and a detailed cookie consent mechanism that complies with GDPR requirements. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security hardening. No evidence of exposed sensitive data or vulnerable libraries was found. The site does not provide a security policy, incident response contacts, or vulnerability disclosure information, which are important for mature security practices. The WHOIS data is privacy-protected, which is typical for .eu domains and does not raise immediate concerns. Overall, the site is secure enough for general e-commerce use but could improve by adding security headers, publishing security policies, and providing clear contact points for security incidents.

Recommendations

  1. Implement and configure HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the website footer.
  3. Add a security.txt file to facilitate vulnerability disclosure and incident reporting.
  4. Provide clear company contact information including email and phone numbers to enhance business credibility.
  5. Improve accessibility features to meet WCAG standards and enhance user experience for all users.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager, Cookiebot for consent management, and integrates multiple analytics and advertising services such as Google Analytics, Microsoft Clarity, Hotjar, and Wisepops. Fonts are loaded via Google Fonts with WebFont Loader. The site is responsive and optimized for mobile devices with viewport meta tags and mobile-friendly icons. Performance is moderate with asynchronous loading of scripts and deferred loading where applicable. SEO metadata is present but minimal, with empty description and keywords meta tags. No CMS or hosting provider information is directly detectable from the HTML. The site uses HTTPS and has canonical and alternate hreflang tags for SEO. Overall, the technical implementation is solid but could benefit from enhanced SEO metadata and improved accessibility 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.
