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

Obchodní a technologický holding a.s. is a Czech investment holding company focused on technology and startups. The company provides a portfolio of services including lead management, mobile app development, web notifications, LED panel rentals, and digitalization solutions for municipalities. Their market position is that of an innovator and quality leader in their sectors, targeting businesses and startups primarily in the Czech Republic and Slovakia. The website content is professional and well-structured, supporting their business model and market positioning. Technically, the website uses standard web technologies including HTML5, CSS, JavaScript, and popular libraries such as jQuery, Swiper.js, and BaguetteBox.js. Google Analytics and Google Tag Manager are used for tracking, but no explicit privacy or cookie policies are present, indicating a gap in privacy compliance. The site shows moderate performance and basic mobile optimization. From a security perspective, the site uses HTTPS and does not expose sensitive data or vulnerable libraries. However, no security headers were detected, and there is no visible incident response or security policy information. The lack of WHOIS data reduces trust and transparency, which is a concern for legitimacy. Overall, the security posture is moderate but could be improved with better privacy compliance and security best practices. The overall risk assessment suggests a generally trustworthy and professional business website with some compliance and transparency gaps. Strategic recommendations include implementing privacy and cookie policies, adding security headers, improving mobile and accessibility features, and enhancing contact and incident response information to strengthen trust and security posture.

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

11 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

The company operates as a horizontally integrated investment holding focusing on technology startups and firms. Their competitive advantage lies in their diversified portfolio and expertise in digital solutions such as mobile apps and digital signage. Revenue streams likely include software development, leasing of LED panels, and digital services for municipalities. The target customers are businesses and local governments in the Czech Republic and Slovakia. The presence of multiple subsidiary domains indicates a broad partnership ecosystem. Growth indicators include recent acquisitions and product launches. The company maintains a professional online presence but lacks some transparency in domain registration data.

Security posture

The current security maturity level is moderate. The website uses HTTPS and avoids exposing sensitive data. However, the absence of security headers and privacy policies indicates gaps in security best practices and compliance with GDPR. No incident response or vulnerability disclosure information is provided, limiting readiness for security events. The use of third-party tracking scripts without consent mechanisms further impacts privacy compliance. There is no evidence of certifications or formal security frameworks. Overall, the security culture appears basic and would benefit from formalization and transparency improvements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to comply with GDPR.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish clear contact information for security incidents and designate a Data Protection Officer if applicable.
  4. Improve mobile responsiveness and accessibility to enhance user experience and compliance.
  5. Regularly audit and update third-party scripts and technologies to mitigate vulnerabilities and privacy risks.

Technical notes

Notes

The website is built on a traditional HTML/CSS/JavaScript stack with popular libraries like jQuery and Swiper.js for UI components. Google Analytics and Tag Manager are integrated for analytics and marketing. The site lacks a detected CMS, suggesting a custom or static site approach. Performance is moderate with room for improvement in mobile optimization and accessibility. No hosting provider information is available. The technical implementation is solid but could benefit from modernization and enhanced security configurations.
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.
