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

5 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 positions itself as a key player in the Czech e-commerce sector, focusing on electronics and computer hardware. Its integration with Allegro provides access to a large marketplace audience, enhancing its market reach. The business model is retail-oriented with a focus on consumer electronics. While direct contact information is not prominently displayed, the use of Allegro's platform suggests reliance on their infrastructure for customer management and transactions. The company benefits from Allegro's brand and technical ecosystem, which supports analytics, marketing, and compliance. Growth potential is linked to Allegro's platform expansion and the increasing demand for online electronics retail in the region.

Security posture

CZC.cz exhibits a solid security foundation with HTTPS and modern security headers. The site uses nonce attributes in scripts to mitigate injection risks and employs cookie consent banners aligned with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure program limits transparency and may impact security maturity perception. Enhancing these areas would improve incident readiness and stakeholder trust. The current security posture is adequate for an e-commerce platform but could benefit from formalized policies and public disclosures.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information to facilitate reporting and communication.
  4. Enhance website accessibility features to improve inclusivity and compliance.
  5. Regularly audit third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built on a modern frontend architecture using ES6 JavaScript modules and CSS bundles, optimized for performance and mobile responsiveness. It leverages Allegro's proprietary UI components and analytics tools, indicating a tightly integrated platform solution. The use of manifest.json suggests PWA capabilities. Hosting and domain registration are managed by reputable providers, ensuring stability and security. SEO is well addressed with proper meta tags and canonical links. However, the site could improve accessibility standards and provide more explicit technical documentation or developer resources. Overall, the technical infrastructure supports a reliable and scalable e-commerce experience.
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.
