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

ATC Market is a well-established e-commerce platform operated by AT Computers a.s., offering a broad range of technology products including computers, servers, accessories, and consumer electronics primarily targeting the Czech and Slovak markets. The website demonstrates a mature digital presence with a comprehensive product catalog, mobile applications, and a network of partner companies. Technically, the site uses modern web technologies such as jQuery, Bootstrap, and Owl Carousel, and is built likely on an ASP.NET MVC framework. The website is mobile-optimized and provides a good user experience with clear navigation and relevant content. Security-wise, while HTTPS is presumably enabled, explicit security headers and policies are not evident, and no incident response contacts are provided. The absence of WHOIS data for the domain is a notable concern, reducing domain trustworthiness, but the website content and business information align with a legitimate and established company. Privacy and cookie policies are comprehensive and GDPR compliant, reflecting good privacy practices. Overall, the site scores well on content quality, technical implementation, and privacy compliance, with room for improvement in security posture and domain transparency.

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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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.

Business context

Business profile

AT Computers a.s. operates ATC Market as a key player in the Czech and Slovak IT retail sector, leveraging a multi-channel business model combining online sales with physical partner networks. The company targets IT professionals, businesses, and consumers seeking technology products. Their competitive advantage lies in a broad product range, established brand, and regional presence. The business model focuses on e-commerce retail and B2B partnerships, supported by mobile applications and warranty services. The presence of multiple partner domains indicates a strong ecosystem. Growth indicators include continuous product updates and active content marketing. Strategic observations suggest the company could enhance trust by improving domain registration transparency and publishing explicit security policies.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and cookie consent mechanisms in place. However, the lack of visible security headers, absence of explicit security or incident response policies, and missing WHOIS data are weaknesses. No vulnerabilities or exposed sensitive data were detected in the HTML content. GDPR compliance is evident through privacy policies and cookie management. The security posture would benefit from implementing HTTP security headers, publishing incident response contacts, and ensuring domain registration transparency to enhance trust and resilience.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page including incident response and abuse contact information.
  3. Ensure domain WHOIS data is properly registered and publicly available to improve legitimacy and trust.
  4. Regularly audit and update SSL/TLS configurations to maintain strong encryption standards.
  5. Enhance accessibility features and SEO metadata to improve user experience and search engine ranking.

Technical notes

Notes

The website uses a modern technology stack including jQuery, Bootstrap, Owl Carousel, and Modernizr, likely built on ASP.NET MVC. The site is mobile-optimized with responsive design and includes a mobile app bridge script indicating integration with iOS and Android apps. Performance is moderate with some heavy image banners and carousel elements. SEO is supported by meta tags and structured navigation. Accessibility is basic but could be improved. No CMS is explicitly detected. Hosting provider details are not available from the content. Technical risks include potential outdated libraries and missing security headers which could impact security and 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.
