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

CLOUDMC is a Czech-based media and web services provider specializing in cloud-hosted websites and a network of local city portals. Founded in 2014, the company operates multiple thematic and city-focused portals, targeting a general Czech audience. It also offers web development and AI training services through partner sites. The website demonstrates a good level of content quality, consistent branding, and a clear navigation structure optimized for mobile devices. Technically, it uses modern frontend technologies such as Tailwind CSS, Leaflet.js for maps, and Google Tag Manager for analytics. Security posture is moderate with HTTPS implied but lacks explicit security headers and has minor PHP code notices. Privacy compliance is well addressed with a cookie consent mechanism and links to GDPR and terms of service pages. Overall, the site is legitimate, stable, and professionally maintained, though improvements in security headers and code hygiene are recommended.

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

  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
      • 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 business operates primarily in the media sector with a focus on local news and city portals, serving Czech cities and neighborhoods. Its business model combines content publishing with web development and AI training services via partner companies. The company leverages a network of related domains to expand its reach and diversify offerings. The presence of social media channels and cookie compliance indicates a mature digital presence. The domain age and registrar data support a stable and consistent business operation. Revenue streams likely include advertising, web development contracts, and training fees. The partnership ecosystem includes Studiomc.cz and Akademieai.cz, enhancing service breadth.

Security posture

The website employs HTTPS and a cookie consent mechanism, indicating baseline security and privacy awareness. However, the absence of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces its security robustness. A PHP notice about session handling suggests minor backend code issues that could affect session security. No incident response or security policy information is found, indicating limited transparency in security governance. No vulnerability disclosure or security.txt files are present. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, fixing code issues, and publishing security policies.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Resolve PHP session notice errors to ensure proper session management and avoid potential session fixation or hijacking risks.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  5. Expand SEO optimization with richer meta tags and structured data to improve search engine visibility.

Technical notes

Notes

The website uses a modern frontend stack with Tailwind CSS for styling, Leaflet.js for interactive maps, and AOS for animations. Google Tag Manager is used for analytics, indicating a structured approach to tracking. The site is mobile responsive with a well-structured navigation menu including a mega menu and mobile toggle. Minor technical debt is noted in PHP backend code with session warnings. Performance is moderate with external dependencies on CDNs and Google services. Hosting is likely provided by Wedos, a Czech hosting provider consistent with the domain registrar. Opportunities exist to improve performance by optimizing scripts and enhancing accessibility compliance.
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.
