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

Czech Online System s.r.o. operates the website digitalniurednideska.cz, offering specialized digital official notice boards primarily targeting municipalities and local government offices in the Czech Republic. Their business model focuses on providing outdoor digital signage hardware combined with proprietary content management software, enabling remote and automated display of official documents and local information. The company is small-sized, founded in 2011, and presents a professional and consistent brand image with clear contact and reference information. Technically, the website employs common web technologies including jQuery, Swiper.js, and Google Analytics, with a moderate performance profile and good mobile optimization. The digital signage hardware supports Windows and Android platforms, emphasizing all-in-one outdoor solutions with touch capabilities. Privacy compliance is well addressed with GDPR-aligned policies and cookie consent mechanisms. From a security perspective, while HTTPS is implied, explicit security headers are not detected, and no dedicated security or incident response policies are published. The absence of WHOIS data reduces domain trustworthiness, though the website content and company information appear legitimate and professional. No vulnerabilities or malicious content were identified. Overall, the website scores well in content quality, privacy compliance, and business credibility, but could improve in security posture and transparency. Strategic recommendations include enhancing security headers, publishing security policies, and resolving WHOIS data visibility to strengthen trust and compliance.

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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube

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

  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 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 occupies a niche market providing digital signage solutions tailored for public sector clients such as municipalities and offices. Their competitive advantage lies in combining hardware with custom software for automated content management, supported by training and after-sales service. Revenue streams likely derive from hardware sales, software licensing, and maintenance contracts. The presence of multiple regional offices and references to municipal clients indicate a growing footprint. Partnerships, such as with OT Holding, suggest integration within a broader group ecosystem. The business model is B2B focused, targeting government entities requiring modern communication tools. Growth potential exists in expanding digital transformation in public administration.

Security posture

The current security maturity is moderate. The website uses HTTPS and implements cookie consent aligned with GDPR, indicating awareness of privacy requirements. However, the lack of visible security headers (e.g., CSP, HSTS) and absence of published security or incident response policies represent gaps. No vulnerability disclosures or security contact channels are provided, limiting incident handling transparency. The contact form uses required fields but no explicit anti-CSRF or CAPTCHA mechanisms were observed. Overall, the security posture is functional but could benefit from formalized policies, enhanced technical controls, and improved transparency to meet higher compliance standards such as NIS2.

Recommendations

  1. Implement HTTP security headers including Content Security Policy (CSP), Strict-Transport-Security (HSTS), and X-Frame-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Verify and improve SSL/TLS configuration to ensure strong encryption and prevent downgrade attacks.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance accessibility compliance and mobile usability to broaden user inclusivity and satisfaction.

Technical notes

Notes

The website is built on a traditional web stack using jQuery and popular UI libraries like Swiper.js and BaguetteBox.js for interactive elements. Google Analytics and Google Tag Manager are used for visitor tracking and marketing analytics. The site is responsive and mobile-friendly with proper meta tags and SEO elements. However, no modern CMS or framework is detected, suggesting a custom or static site approach. Performance is moderate with room for optimization. Hosting details are not disclosed. The digital signage hardware integrates Windows 10 and Android platforms with all-in-one PC solutions, indicating a hybrid hardware-software ecosystem. Technical risks include missing security headers and potential outdated libraries.
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.
