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

DNS.cz operates as a significant IT distribution intermediary in the Czech Republic, bridging manufacturers and IT solution providers to end customers. The website presents a professional and modern digital presence with a focus on technology distribution services. The company targets IT providers and customers, positioning itself as a key player in the IT solutions market. Technically, the website employs modern JavaScript libraries, Google Tag Manager, and Cookiebot for cookie consent management, indicating a mature digital infrastructure. Security posture is adequate with HTTPS enforced and bot protection via Google reCAPTCHA; however, the absence of explicit security headers and security policies suggests room for improvement. Privacy compliance is supported by a detailed cookie consent mechanism, though no explicit privacy policy or terms of service pages were detected in the provided content. The lack of WHOIS data limits domain legitimacy verification, but the website content and technology usage support a legitimate business operation. Overall, DNS.cz demonstrates a solid business and technical foundation with moderate security and privacy compliance maturity.

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 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

  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 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

DNS.cz holds a strong market position as an IT distribution company in the Czech Republic, focusing on connecting IT manufacturers with solution providers and end customers. Its business model revolves around distribution and intermediary services in the technology sector. The company leverages partnerships with major platforms such as Google for analytics and marketing, and LinkedIn for professional networking. The website content is well-aligned with its business focus, targeting IT professionals and organizations. Growth indicators include the use of advanced tracking and marketing tools, suggesting active customer engagement strategies. However, the absence of visible contact information and detailed corporate data on the website may limit direct customer trust and engagement. Strategic partnerships and transparent marketing practices enhance its competitive advantage in the IT distribution market.

Security posture

The website enforces HTTPS and integrates Google reCAPTCHA to mitigate automated abuse, reflecting a baseline security posture. Cookie consent is implemented with granular user controls, supporting GDPR compliance. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces defense-in-depth. No security.txt or incident response contact information was found, which could hinder vulnerability reporting and incident management. The WHOIS data is unavailable, which raises concerns about domain registration transparency. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the security posture is moderate but would benefit from enhanced header configurations, explicit security policies, and improved transparency in domain registration.

Recommendations

  1. Implement standard security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to strengthen browser security.
  2. Publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  3. Provide explicit security and incident response policies, including a security.txt file for vulnerability disclosure.
  4. Enhance transparency by publishing verified WHOIS registrant information or justifying privacy protection.
  5. Add clear company contact information including emails and phone numbers to improve business credibility and user trust.

Technical notes

Notes

The website uses a modern JavaScript-based frontend with libraries such as AOS for animations, Google reCAPTCHA for bot protection, and Cookiebot for cookie consent management. Google Tag Manager is integrated for analytics and marketing tracking. Fonts are loaded via Adobe Typekit. The site is mobile-optimized with responsive meta tags and good navigation clarity. Performance is moderate, with asynchronous loading of scripts to improve speed. No CMS or hosting provider information was detected. Accessibility features are basic but present. SEO is supported by proper meta tags and Open Graph data. Technical risks include missing security headers and lack of explicit privacy and security documentation. Overall, the technical infrastructure is solid but could be improved with enhanced security configurations and more transparent business information.
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.
