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

      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

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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

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 Czech export firms, domestic businesses, e-commerce operators, and event organizers, leveraging its 22 years of digital expertise. Its competitive advantages include a strong brand reputation, multiple awards, and a comprehensive service offering that integrates marketing and technology. Revenue streams likely come from digital project delivery, marketing campaigns, and ongoing digital ecosystem management. The partnership ecosystem includes notable Czech brands such as Jablotron and CPI. The company demonstrates growth through diverse client sectors and a focus on strategic digital business management.

Security posture

The website exhibits a moderate to strong security posture with enforced HTTPS, cookie consent, and no visible sensitive data exposure. However, it lacks published security policies, incident response information, and security.txt files, which are important for transparency and vulnerability management. The absence of advanced security headers and explicit incident response contacts suggests room for improvement. GDPR compliance is well addressed through detailed privacy and cookie policies. Overall, the security maturity is good but could be enhanced with formalized policies and additional technical controls.

Recommendations

  1. Publish a formal security policy and incident response plan accessible on the website.
  2. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to harden the site.
  3. Create and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to meet higher compliance standards.
  5. Regularly review and update third-party scripts and tracking tools to mitigate potential vulnerabilities.

Notes

The website uses a modern technology stack including Google Tag Manager, Google Analytics, and Leady for tracking and marketing. It loads resources over HTTPS and uses custom CSS and JavaScript for UI/UX. Hosting is provided by Czech providers indicated by nameservers.

The site is well-structured with clear navigation and professional design, supporting a positive user experience.
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.
