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

TRANSALPINUS s.r.o. operates the website bezpecnavoda.cz as a distributor of KATADYN water filtration and purification products. The company targets travelers, outdoor enthusiasts, humanitarian organizations, and military units by providing high-quality portable water filters, chemical disinfectants, UV purifiers, and desalination devices. The website reflects a professional retail business model with a focus on safe water solutions for travel and outdoor activities. The company is based in the Czech Republic and provides clear contact and company registration information, enhancing business credibility. Technically, the website is built on the Webnode CMS platform and hosted via AWS Cloudfront CDN, ensuring good performance and mobile optimization. It uses modern web technologies including JavaScript and CSS, and integrates Google Tag Manager for analytics. However, the site lacks visible privacy and cookie policies, security headers, and incident response information, which are areas for improvement in compliance and security posture. Security-wise, the site enforces HTTPS and does not expose sensitive data, but the absence of security headers and vulnerability disclosure mechanisms limits its security maturity. The WHOIS data is unavailable, which reduces trust in domain registration transparency, though the website content and company information support legitimacy. Overall, the site is safe, professional, and trustworthy but would benefit from enhanced privacy compliance and security best practices. Strategically, the company should prioritize publishing comprehensive privacy and cookie policies, implement security headers, and provide clear incident response contacts. These steps will improve compliance with GDPR and enhance user trust. Additionally, publishing a security.txt file and improving accessibility features would further strengthen the website's security and usability profile.

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.

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

TRANSALPINUS s.r.o. holds a strong position as a specialized retailer and distributor of KATADYN water filtration products in the Czech market. The company leverages the reputable KATADYN brand, known globally for quality and innovation in portable water treatment solutions. Their business model focuses on retail sales through an e-shop and direct customer engagement, targeting outdoor enthusiasts, travelers, humanitarian organizations, and military clients. The website content highlights partnerships with international aid organizations and military units, indicating a trusted product portfolio. The company maintains a clear contact and legal presence, supporting operational transparency. Growth opportunities may include expanding digital marketing efforts and enhancing compliance to meet evolving data protection regulations.

Security posture

The website demonstrates a moderate security posture with HTTPS enforced and no visible exposure of sensitive data. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement in protecting against common web vulnerabilities. The lack of visible privacy and cookie policies, as well as no published incident response or vulnerability disclosure information, suggests gaps in compliance and security readiness. The use of Google Tag Manager introduces tracking capabilities but without clear privacy disclosures. The missing WHOIS data reduces transparency about domain ownership, which could be a concern for trust. Overall, the security maturity is adequate for a retail website but should be enhanced to align with best practices and regulatory requirements.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit GDPR compliance statements and consent mechanisms.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Create and publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response transparency.
  4. Add clear incident response contact information, including security or abuse email addresses, to enhance trust and readiness.
  5. Improve website accessibility features to comply with standards and enhance user experience for all visitors.

Technical notes

Notes

The website is built on the Webnode CMS platform and utilizes AWS Cloudfront CDN for hosting static assets, contributing to moderate performance and good mobile optimization. The technology stack includes standard web technologies such as JavaScript and CSS, with Google Tag Manager integrated for analytics and tracking. Meta tags and Open Graph data are properly configured for SEO and social media sharing. However, the site lacks advanced security headers and visible privacy compliance mechanisms. The WHOIS data is missing, which may indicate privacy protection or registration issues. Overall, the technical infrastructure is modern and functional but could benefit from enhanced security configurations and compliance features to reduce technical debt and risks.
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.
