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

4 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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.

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Martinus operates as an essential retail and e-commerce business in Slovakia, focusing on book sales and related products. Its business model revolves around online retail with fast shipping and customer service. The company leverages partnerships with analytics and marketing platforms such as Google Analytics, Algopine, and RTB House for retargeting. The use of Cookiebot indicates a commitment to GDPR compliance. The website's digital maturity is evident through the use of modern frameworks and tracking technologies. However, the lack of visible contact information and privacy policy in the provided content suggests areas for transparency improvement. The company appears to maintain a strong market position with consistent branding and a large product catalog.

Security posture

The website enforces HTTPS and uses Sentry for error tracking, indicating a proactive approach to security monitoring. Cookie consent is managed via Cookiebot, supporting GDPR compliance. However, the absence of explicit security headers in the HTML and no visible security or incident response policies limit the security maturity level. No vulnerabilities or exposed sensitive data were detected in the content. The site would benefit from publishing a security policy, incident response contacts, and implementing recommended HTTP security headers to enhance protection against common web threats.

Recommendations

  1. Add and enforce HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a clear privacy policy and terms of service accessible from the homepage.
  3. Provide explicit contact information including emails and phone numbers for customer support and security incident reporting.
  4. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

The website uses a modern tech stack including Font Awesome 6, Turbo, Hotwired, and multiple third-party analytics and tracking services. It loads asynchronously and defers scripts for performance optimization. Cookie consent is handled by Cookiebot with detailed cookie disclosures. The site is mobile optimized and uses responsive design techniques. However, no CMS or hosting provider details were explicitly found. Performance is moderate with room for improvement in accessibility features. The technical implementation supports a professional e-commerce experience but could benefit from enhanced security headers and more transparent privacy documentation.
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.
