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

Tehno-mag is a Croatian e-commerce retailer specializing in electronics and gadgets from well-known brands. Established in 2015, it offers fast and reliable delivery services with multiple payment options including installments up to 36 months. The website targets general consumers in Croatia, providing a broad range of technology products with a focus on convenience and customer service. The business maintains a moderate market position as a local electronics webshop with competitive offerings. Technically, the website employs modern tracking and consent management technologies such as Google Analytics, Google Tag Manager, Cookiebot, and Cloudflare DNS/CDN services. The site is mobile-optimized and demonstrates good SEO and accessibility practices, although no explicit CMS was detected, suggesting a custom-built platform. Performance is moderate with room for optimization. From a security perspective, the site uses HTTPS with a good SSL configuration and integrates Google reCAPTCHA for bot protection. Cookie consent is managed via Cookiebot, ensuring GDPR compliance. However, explicit security headers like Content-Security-Policy and X-Frame-Options were not detected and should be implemented to enhance security posture. No vulnerabilities or exposed sensitive data were found. Overall, the website is safe, professional, and trustworthy with no adult or questionable content. The domain registration data is consistent with the business claims, showing a legitimate and established online presence. Strategic recommendations include enhancing security headers, auditing third-party scripts, and formalizing security and incident response policies to further strengthen trust and compliance.

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. 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 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. 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 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

Tehno-mag operates in the retail and e-commerce sectors, focusing on consumer electronics in the Croatian market. Its business model revolves around online sales with value-added services such as fast delivery and flexible payment options. The company leverages partnerships with known brands and uses digital marketing tools to reach its audience. The presence of a related domain (tehnomag.com) suggests a broader brand ecosystem or sister site. The company targets general consumers seeking technology products, positioning itself as a reliable local alternative to larger international retailers. Growth indicators include multi-channel marketing and comprehensive cookie consent management, reflecting awareness of regulatory compliance and customer trust.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Google reCAPTCHA to mitigate automated abuse. Cookie consent is managed effectively through Cookiebot, supporting GDPR compliance. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options indicates room for improvement. No evidence of vulnerabilities or exposed sensitive data was found in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. No vulnerability disclosure or security.txt file was detected, which could be considered for future implementation to enhance security culture and incident handling readiness.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information to improve transparency and trust.
  3. Conduct regular audits of third-party scripts and libraries to identify and remediate potential vulnerabilities.
  4. Consider implementing a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features and performance optimizations to improve user experience and SEO.

Technical notes

Notes

The website uses a combination of Google Analytics, Google Tag Manager, Cookiebot for consent management, and Cloudflare for DNS and likely CDN services. The presence of Google reCAPTCHA indicates bot mitigation efforts. The site appears to be custom-built or uses a proprietary CMS, as no common CMS signatures were detected. Performance is moderate with good mobile optimization and SEO meta tags present. Accessibility is basic but could be improved. The site uses modern JavaScript libraries and asynchronous script loading to optimize page load times. Overall, the technical infrastructure supports a stable e-commerce platform but could benefit from enhanced security headers and performance tuning.
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.
