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

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 company holds a strong position in the Czech automotive parts market with over two decades of operation, indicating stability and experience. Its business model combines e-commerce with distribution, targeting a diverse customer base from individual vehicle owners to industry professionals. The product portfolio is broad, covering classic and original parts, which may provide competitive advantages in niche markets. The presence of social media channels and magazines suggests active marketing and customer engagement. The company is registered with clear legal and tax identifiers, reinforcing legitimacy. No direct partnerships or subsidiaries were identified from the website content. Growth indicators include regular news updates and product promotions. The company appears focused on maintaining a solid regional presence with potential for expansion.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used, but no explicit security headers such as CSP, HSTS, or X-Frame-Options were detected in the provided data, which are important for mitigating common web attacks. The login form uses password fields with minlength attributes, but no advanced protections like CAPTCHA or multi-factor authentication are evident. The use of older jQuery versions could expose the site to known vulnerabilities if not patched. Cookie consent is implemented, indicating awareness of privacy regulations, but no explicit privacy policy or incident response contacts are published. There is no evidence of vulnerability disclosure or security.txt files. Overall, the security posture is functional but requires improvements to align with best practices and regulatory compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade JavaScript libraries to the latest secure versions and regularly patch dependencies.
  3. Publish clear privacy policy and terms of service pages to enhance compliance and user trust.
  4. Establish and publicize an incident response policy and contact channels for security issues.
  5. Enforce HTTPS site-wide and consider adding multi-factor authentication for user login.

Technical notes

Notes

The website is built on a custom ASP-based CMS platform, utilizing jQuery 3.3.1 and related libraries for UI and interactivity. Google Fonts are used for typography, and Owl Carousel provides dynamic content display. Hosting is managed via Dial Telecom, as indicated by the nameservers. The site shows moderate performance and basic mobile optimization. SEO is supported by meta tags and JSON-LD structured data for search engines. Accessibility features are minimal but present. The technical stack is somewhat dated, particularly with older JavaScript libraries, which may pose security and maintenance challenges. There is opportunity for modernization, including adopting modern frameworks, improving mobile responsiveness, and enhancing accessibility compliance.
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.
