CLA Czech Republic is a professional services firm providing integrated consulting services including audit, tax advisory, accounting, legal consulting, corporate finance, and IT support.

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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, LinkedIn, YouTube

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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 operates in the finance sector, targeting medium to large businesses requiring integrated consulting services. Its affiliation with CLA Global enhances its market credibility and reach. The business model focuses on professional services with a broad portfolio including audit, tax, legal, and IT support. The website content and structure indicate a well-established firm with over 30 years of experience, although domain age cannot be verified due to missing WHOIS data. The firm maintains active social media channels and provides multimedia content to engage clients. The lack of explicit contact details on the homepage suggests contact is likely managed via dedicated pages or forms. The company emphasizes team collaboration and employee benefits, indicating a strong internal culture.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA v3 to protect forms from automated abuse. No security headers were detected in the provided data, which is an area for improvement. There is no evidence of exposed sensitive data or vulnerable libraries. The site uses up-to-date WordPress and plugins, reducing risk from known vulnerabilities. Privacy and cookie policies are present and indicate GDPR compliance. Incident response and security policy pages are not found, which could be enhanced to improve transparency and readiness. Overall, the security posture is solid for a professional services website but could benefit from additional security headers and explicit incident response information.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Regularly audit and update all plugins and WordPress core to mitigate vulnerabilities.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Consider publishing explicit contact information for security incidents and data protection officer.

Technical notes

Notes

The website is built on WordPress 6.8.2 with popular plugins including Yoast SEO, Contact Form 7, and WPML for multilingual support. It uses Google reCAPTCHA v3 for bot protection and jQuery 3.7.1 with jQuery UI components. The site is moderately performant with good mobile optimization and SEO practices. Lazy loading is implemented for images. No hosting provider information is available from the data. The site uses a modern tech stack typical for professional service firms but could improve performance by optimizing scripts and adding security headers. The site structure and navigation are clear and user-friendly.
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.
