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

7 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

      Detected services: Google Analytics, Google APIs

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

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 technology sector, focusing on digital marketing and web solutions. Their business model revolves around providing customized services including web and e-shop creation, digital marketing campaigns, mobile and web applications, and branding design. The presence of notable client logos and partner badges indicates a strong market position and trust within the Czech market. Their target audience includes SMEs and larger enterprises seeking comprehensive online marketing and development services. The company shows growth potential through diversified service offerings and strategic partnerships with major advertising platforms. No parent or subsidiary companies were identified, suggesting an independent operation.

Security posture

The website demonstrates a good security posture with HTTPS enforced and integration of Google reCAPTCHA to protect forms from abuse. The cookie consent mechanism is comprehensive, allowing users granular control over cookie categories, supporting GDPR compliance. However, no explicit security policy or incident response contacts are published, which could be improved to enhance transparency and readiness. Security headers data was not available for review, and no vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security maturity is good but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add and verify security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  3. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance transparency by detailing data retention policies and privacy practices explicitly.
  5. Consider adding a dedicated page or section for vulnerability disclosure and responsible reporting.

Technical notes

Notes

The website uses a modern technology stack including Bootstrap 5 for responsive design, jQuery for DOM manipulation, and the Nette PHP framework for backend forms and AJAX handling. Google reCAPTCHA is integrated for spam protection. CookieConsent.js manages GDPR-compliant cookie consent with detailed user options. Performance is moderate with CDN usage for libraries, though no explicit hosting provider information is available. The site is mobile-optimized with excellent accessibility and SEO practices evident from meta tags and structured navigation. Technical debt appears low, but the absence of visible security headers suggests room for improvement in security hardening.
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.
