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

9 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

  2. Security headers

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 government and manufacturing sectors, focusing on secure printing and digital services. Its business model combines traditional security printing with innovative digital solutions, supported by an e-commerce platform for collectors and partners. The firm benefits from a long history, ISO certifications, and participation in transparency initiatives, which enhance its competitive advantage. Target customers include government agencies and commercial entities requiring secure documents and tracking solutions. The company shows growth potential through digital service expansion and maintains a strong brand presence in the Czech Republic.

Security posture

The website exhibits a mature security posture with enforced HTTPS, integration of Google reCAPTCHA for form protection, and adherence to ISO 14298 security printing standards. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not clearly present and should be implemented to harden defenses. No vulnerabilities or exposed sensitive data were detected in the analysis. The absence of a public incident response or vulnerability disclosure page is a minor gap. Overall, the security measures align well with the company's critical role in secure document production.

Recommendations

  1. Implement comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to enhance browser security.
  2. Publish an incident response or abuse contact page to improve transparency and readiness for security events.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit third-party scripts and plugins to ensure no vulnerable libraries are in use.
  5. Enhance accessibility features and conduct periodic performance optimizations to maintain excellent 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.
