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

OK HOLDING a.s. operates as a holding company specializing in corporate insurance, personal finance, insurance intermediary networks, grant consulting, investments, and real estate. The company maintains a network of subsidiaries primarily in the Czech Republic and Slovakia, positioning itself as a professional and established player in the finance and real estate sectors. The website reflects a professional business presence with clear branding and a focus on collaboration among experts in their respective fields. Technically, the website uses modern tools such as Google Tag Manager and Google Analytics, and is built on simploCMS, indicating a moderate level of digital maturity. The site is mobile-optimized and SEO-friendly, though accessibility features could be improved. Security posture is adequate with HTTPS enabled and no visible vulnerabilities, but lacks security headers and formal security policies. The absence of WHOIS data reduces transparency and trustworthiness somewhat, but the overall business credibility remains high based on website content and company information. Strategic recommendations include enhancing privacy compliance, adding security headers, and publishing incident response and vulnerability disclosure information to strengthen trust and security culture.

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

8 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

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 holds a medium-sized market position in the finance and real estate sectors, leveraging a diversified portfolio of subsidiaries that cover corporate insurance, personal finance, investments, and grant consulting. Its business model is based on a holding structure that facilitates cooperation among specialized companies, targeting professional clients and partners. The presence of multiple subsidiary domains and a consistent branding approach suggests a well-organized partnership ecosystem. Revenue streams likely derive from insurance brokerage, financial advisory, investment management, and real estate services. The company appears to focus on growth through collaboration and specialization, with a clear emphasis on professionalism and trustworthiness in its market approach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no exposed sensitive data. However, the lack of security headers such as Content Security Policy, HSTS, and X-Frame-Options indicates room for improvement. No incident response or security contact information is provided, and there is no evidence of a vulnerability disclosure program or security.txt file. Privacy compliance is minimal, with no visible privacy or cookie policies, which could pose regulatory risks under GDPR. Overall, the security posture is functional but could be significantly enhanced by adopting best practices in headers, policies, and transparency to reduce risk and improve stakeholder confidence.

Recommendations

  1. Implement comprehensive privacy and cookie policies with explicit GDPR compliance and consent mechanisms.
  2. Add security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  3. Publish incident response contact details and establish a vulnerability disclosure program or security.txt file to improve transparency and responsiveness.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly review and update WHOIS information to ensure domain registration transparency and trust.

Technical notes

Notes

The website is built on simploCMS and uses Google Tag Manager and Google Analytics for tracking and analytics. The HTML structure is valid and includes proper meta tags for SEO and social sharing (Open Graph). Performance is moderate with asynchronous loading of scripts. Mobile optimization is good, with responsive design elements. However, accessibility is basic and could be improved. The absence of security headers is a technical gap. Hosting provider details are not evident from the HTML content. Overall, the technical infrastructure supports a professional online presence but could benefit from modernization in security and accessibility practices.
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.
