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

The website www.ferrumin.cz is dedicated to promoting and providing information about Ferrumin, a dietary supplement designed to support red blood cell production, particularly targeting blood donors, anemic individuals, women of reproductive age, vegetarians, and vegans. The site primarily serves as an informational and referral platform linking to partner e-commerce sites for product purchase. The business operates within the healthcare sector, focusing on nutritional supplements, with a small-scale market presence in the Czech Republic. The content is relevant and well-aligned with the target audience but lacks comprehensive business and contact information. From a technical perspective, the website employs basic web technologies including jQuery and the Nette framework for form handling. The site structure is simple with moderate performance and basic mobile optimization. However, there is no evidence of a CMS or advanced hosting details. SEO and accessibility features are minimal but functional. Security posture is weak due to the absence of HTTPS verification in the provided data, missing security headers, and lack of privacy and cookie policies. Security analysis reveals significant gaps including no WHOIS data availability, which raises concerns about domain legitimacy and trustworthiness. The absence of privacy compliance mechanisms and contact information further diminishes the security and compliance posture. No signs of WAF or blocking mechanisms were detected, and the content is safe with no adult or explicit material. Overall, the site is functional but requires improvements in security, compliance, and transparency to enhance trust and user confidence. Strategic recommendations include implementing HTTPS with strong SSL/TLS, publishing privacy and cookie policies with GDPR compliance, adding clear contact and incident response information, and enhancing security headers. These steps will improve the site's security posture, compliance, and business credibility.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

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

Ferrumin.cz operates as a niche healthcare supplement website focused on iron supplementation for blood health. The business model relies on directing users to partner e-commerce platforms for sales rather than direct transactions. The site targets specific customer segments including blood donors, anemic patients, and vegetarians/vegans, indicating a focused market approach. The partnership ecosystem includes related healthcare and supplement sites, suggesting a collaborative network. The lack of direct contact and company information limits transparency but the product positioning is clear. Growth potential depends on expanding digital presence and improving trust signals. Revenue streams are likely affiliate or referral based. Competitive advantages include specialized product focus and partnerships with established healthcare portals.

Security posture

The current security maturity level of www.ferrumin.cz is low. Critical vulnerabilities include the absence of WHOIS registration data, which undermines domain legitimacy and trust. The website lacks HTTPS confirmation in the provided data, no security headers are detected, and there are no privacy or cookie policies, indicating poor compliance with GDPR and other data protection regulations. No incident response or security contact information is available, limiting the ability to handle security events effectively. The site does not expose sensitive data or show signs of vulnerable libraries but overall security best practices are not observed. The security culture appears minimal, with no visible certifications or policies. These gaps pose risks to user trust and regulatory compliance.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and ensure all site content is served securely.
  2. Publish comprehensive privacy and cookie policies aligned with GDPR requirements and implement a cookie consent mechanism.
  3. Add clear contact information including a dedicated security or abuse email address for incident reporting.
  4. Configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  5. Enhance mobile responsiveness and accessibility to improve user experience and compliance with accessibility standards.

Technical notes

Notes

The website uses a simple technical stack with jQuery 3.1.1 and Nette Forms for client-side scripting and form handling. The HTML structure is basic but valid, with linked CSS stylesheets for layout and design. There is no evidence of a CMS or advanced backend platform. Performance is moderate with no explicit optimization detected. Mobile optimization is basic, lacking advanced responsive design features. SEO is minimally addressed through meta tags and Open Graph properties but lacks structured data like JSON-LD. No analytics or tracking scripts were found, indicating minimal data collection. The site is hosted on an unknown provider with no DNS or hosting details available. Technical debt appears low but modernization opportunities exist, especially in security and compliance implementations.
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.
