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

TopTax is a Czech Republic-based service provider specializing in accounting, tax, administration, and communication with authorities. The company positions itself as a top partner for these services, targeting businesses and individuals needing professional financial and administrative support. The website is built using modern web technologies such as Gatsby, React, and Tailwind CSS, indicating a contemporary digital infrastructure. However, the site content is basic and lacks comprehensive business and compliance information. Security posture is moderate with HTTPS enabled but missing critical security headers and policies.

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

6 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

TopTax operates in the accounting and tax service sector within the Czech Republic, focusing on small to medium-sized clients. The business model revolves around providing essential financial and administrative services, with a market position emphasizing partnership and reliability. The website content is primarily in Czech and targets local businesses and individuals. There is no evidence of partnerships or subsidiaries from the website content. The lack of detailed business registration and compliance information suggests a need for enhanced transparency to build greater trust with clients and regulators.

Security posture

The website employs HTTPS, ensuring encrypted communication. However, it lacks important security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security, which are best practices to mitigate common web vulnerabilities. No privacy or cookie policies are present, indicating potential GDPR compliance gaps. There is no visible incident response or security contact information, which is a concern for handling security incidents. The absence of WHOIS data reduces the ability to verify domain legitimacy. Overall, the security maturity is basic and requires enhancements to meet industry standards and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies to comply with GDPR and inform users about data handling.
  2. Add security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve web security.
  3. Publish clear contact information for security incidents and designate a Data Protection Officer if applicable.
  4. Ensure WHOIS domain registration information is accurate and publicly available to enhance trust.
  5. Conduct regular security audits of third-party scripts and dependencies to prevent vulnerabilities.

Technical notes

Notes

The website is built on a modern static site generator (Gatsby) with React and styled using Tailwind CSS, which supports good performance and responsive design. The site appears moderately optimized for mobile devices and has a clear navigation structure. However, there is no evidence of advanced SEO or accessibility features beyond basic implementation. Hosting provider details are not discernible from the content. Performance is moderate, likely benefiting from static site generation but could be improved with further optimization. Technical debt appears low but the lack of security headers and compliance documentation indicates areas for modernization and risk mitigation.
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.
