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

The website www.dunamzdy.cz represents a Czech payroll software provider targeting small and medium-sized enterprises and contributory organizations. The site offers a modern payroll system named DUNA MZDY with a free trial version, positioning itself as a specialized solution in the Czech market. The business model revolves around software sales and support for payroll management. Technically, the website employs common analytics and marketing tools such as Google Analytics, Google Tag Manager, and Smartsupp Live Chat, indicating a moderate level of digital maturity. The site is accessible without WAF or blocking mechanisms, and it is mobile-optimized with good SEO practices. However, the absence of WHOIS registration data and lack of visible privacy or terms of service pages reduce the overall trust and compliance posture. Security-wise, HTTPS is enabled, but advanced security headers and policies are not evident. The site lacks explicit contact information and security incident response details, which are important for business credibility and compliance. Overall, the website is functional and professional but would benefit from enhanced transparency and security documentation.

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

10 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 Policy found

      GDPR requires clear information about cookie usage

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 targets the payroll software niche for Czech SMEs and contributory organizations, offering a modern and user-friendly system. Its competitive advantage lies in localized software tailored to the Czech market with a free trial to attract users. The business model is primarily software licensing and support. The website content is professionally presented, but the lack of detailed company information, contact details, and certifications limits the perceived credibility. There is no evidence of partnerships or subsidiaries from the data provided. The marketing ecosystem includes Google Ads and live chat support, indicating active customer engagement. Growth indicators are not visible, and the absence of WHOIS data raises questions about domain registration transparency.

Security posture

The website uses HTTPS, which is mandatory for secure communications. It employs standard marketing and analytics scripts but lacks visible advanced security headers such as Content-Security-Policy or X-Frame-Options. No vulnerabilities or exposed sensitive data were detected in the provided content. The absence of a published privacy policy and terms of service is a compliance gap, especially under GDPR regulations. There is no published incident response or security contact information, which is a weakness in security readiness. The cookie consent mechanism is present, indicating some level of privacy compliance. Overall, the security posture is moderate but could be improved by publishing security policies, enhancing HTTP headers, and providing clear contact channels for security incidents.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Add a terms of service page detailing user rights and obligations.
  3. Provide clear and verified contact information including phone numbers and emails for business and security inquiries.
  4. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Verify and update WHOIS domain registration information to enhance legitimacy and trust.

Technical notes

Notes

The website uses modern web technologies including Google Fonts, Google Analytics, Google Tag Manager, and Smartsupp Live Chat for user engagement and analytics. The HTML content is well structured with appropriate meta tags and Open Graph data for social sharing. The site is mobile optimized and loads with moderate performance. No CMS or hosting provider information was detected. The absence of structured data like JSON-LD limits SEO potential. The site could benefit from improved accessibility features and performance optimizations. Technical debt appears low but transparency and documentation improvements are recommended.
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.
