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

The website www.opel-ihned.cz serves as a comprehensive online platform for listing and filtering Opel brand vehicles available immediately from authorized dealers in the Czech Republic. It aggregates stock and demo vehicles, providing detailed filtering options by model, dealer, engine type, color, equipment, and price. The platform targets consumers seeking to purchase Opel vehicles quickly and conveniently, positioning itself as a trusted intermediary between buyers and authorized dealers. The business model focuses on lead generation and vehicle inventory display, supported by dealer contact information and location mapping. Technically, the site is built on JavaServer Faces with PrimeFaces UI components, enhanced by Bootstrap for responsive design and jQuery for interactivity. It integrates Google Tag Manager, Google Analytics, and Adform for marketing and tracking purposes, alongside a live chat service (Smartsupp). The site is mobile-optimized with good SEO practices, including structured data (JSON-LD) and Open Graph metadata, enhancing search visibility and social sharing. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms, indicating awareness of privacy regulations. However, explicit security headers like Content-Security-Policy or X-Frame-Options are not evident, and no published security or incident response policies are found. The absence of WHOIS data reduces transparency but does not directly imply malicious intent. Overall, the security posture is moderate with room for improvement in policy publication and header implementation. The overall risk assessment suggests a legitimate, professionally maintained automotive sales platform with moderate technical maturity and privacy compliance. Strategic recommendations include publishing clear privacy and security policies, enhancing security headers, and establishing a vulnerability disclosure process to 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

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

  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"

      • 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"

    • 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';…

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 as a specialized automotive marketplace focusing exclusively on Opel vehicles in the Czech market. It leverages partnerships with numerous authorized dealers nationwide, providing a centralized inventory and contact point for consumers. Competitive advantages include real-time inventory updates, detailed filtering capabilities, and integration of dealer contact and location data. Revenue streams likely derive from lead generation fees or dealer advertising. The target customer segment is Czech consumers interested in purchasing new or demo Opel vehicles quickly. Growth indicators include extensive dealer network integration and frequent inventory updates. The partnership ecosystem includes authorized dealers and marketing service providers like Comin.cz. Strategic observations highlight the site's role as a trusted intermediary enhancing dealer reach and consumer convenience in a competitive automotive retail environment.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented, reflecting compliance with basic privacy regulations. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth strategies. No published security policies or incident response contacts reduce transparency and preparedness perception. There is no evidence of a vulnerability disclosure program or security.txt file, which could hinder coordinated vulnerability management. Compliance gaps include lack of visible GDPR privacy policy and limited cookie policy transparency beyond consent UI. Overall, the security culture appears functional but could benefit from formalized policies and enhanced technical controls.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the website footer or main navigation.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  3. Establish and publicize an incident response policy and contact channel (e.g., security@ or abuse@ email) for vulnerability reporting and security incidents.
  4. Create and host a security.txt file to facilitate responsible vulnerability disclosure and improve security transparency.
  5. Regularly audit and update third-party scripts and libraries to ensure no known vulnerabilities are present.

Notes

The website is built on a JavaServer Faces (JSF) framework with PrimeFaces UI components, indicating a mature Java EE technology stack. Frontend technologies include Bootstrap for responsive design and jQuery for DOM manipulation. The site integrates multiple third-party services such as Google Tag Manager, Google Analytics, Adform tracking, and Smartsupp live chat, reflecting a comprehensive marketing and user engagement infrastructure. Performance is moderate with room for optimization, particularly in script loading and asset management. Accessibility features are basic, with potential improvements in ARIA roles and keyboard navigation. SEO is well addressed through meta tags, Open Graph, and JSON-LD structured data. Hosting provider details are not explicit, and no CMS is detected, suggesting a custom or enterprise deployment.
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.
