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

comm4u s.r.o. is a Czech-based marketing and localization agency specializing in social media management, marketing communication, video production, online and print advertising, graphic design, translation, and public relations. The company serves brands and products primarily in the Czech and Slovak markets, with notable long-term clients such as Microsoft Xbox and EA Sports. Their website reflects a professional service provider with clear contact information and a focus on comprehensive marketing solutions. Technically, the website employs common web technologies including jQuery, Google reCAPTCHA, Google Analytics, and Google Maps API. The site is mobile-optimized with good design quality and navigation clarity. However, some technical improvements are recommended, such as adding security headers and resolving Google Maps API loading errors. From a security perspective, the site uses HTTPS and implements reCAPTCHA on its contact form, which are positive indicators. However, the absence of security headers and lack of published privacy or cookie policies indicate room for improvement in compliance and security posture. No critical vulnerabilities or adult content were detected. Overall, the website presents a moderate risk profile with good business credibility but requires enhancements in privacy compliance and security best practices to improve trust and regulatory adherence.

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

    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

      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

comm4u s.r.o. operates as a specialized marketing and localization service provider targeting businesses requiring social media, advertising, translation, and PR services. Their market positioning is strengthened by long-term engagements with major clients, indicating stable revenue streams and industry trust. The business model focuses on service delivery with a strong emphasis on brand communication and localization. The company targets primarily Czech and Slovak markets, leveraging local expertise. The partnership ecosystem includes major global brands, enhancing their competitive advantage. Growth indicators include ongoing projects with high-profile clients and diversified service offerings.

Security posture

The current security maturity level is moderate. The website benefits from HTTPS encryption and uses Google reCAPTCHA to protect its contact form from spam and abuse. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No explicit security or incident response policies are published, which may impact compliance with GDPR and NIS2 requirements. The exposure of the Google Maps API key without visible restrictions could pose a risk of misuse. Data protection practices are not clearly communicated, and no dedicated contact channels for security incidents are provided. Enhancing these areas would improve incident response readiness and security culture.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Restrict Google Maps API key usage to authorized domains to prevent unauthorized use.
  4. Publish an incident response policy and provide dedicated contact channels for security issues.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses a standard technology stack with jQuery, Google Analytics, Google reCAPTCHA, and Google Maps API. The HTML and CSS are valid and the site is mobile responsive with good navigation clarity. Performance is moderate, with some external dependencies that could impact load times. The Google Maps integration currently fails to load correctly, indicating a configuration or API key issue. No CMS or advanced frameworks are detected, suggesting a custom or lightweight implementation. Technical debt appears low but could be improved by modernizing analytics and map integrations 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.
