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

Atmedia is an established independent media agency specializing in advertising sales on thematic TV stations in the Czech Republic. With a 15-year presence, it holds a significant market position, representing 24 measured thematic TV channels and offering targeted advertising solutions to clients including media agencies and advertisers. The website reflects a professional and consistent brand image with comprehensive content about the company's milestones, team, clients, and current operations. Technically, the site uses modern JavaScript libraries such as jQuery, Owl Carousel, and CountUp.js, alongside a cookie consent management system (Orejime) and Google Analytics for tracking. The site is mobile-optimized and well-structured, providing a good user experience. Security posture is moderate with HTTPS usage and cookie consent, but lacks visible HTTP security headers and detailed security policies. WHOIS data is unavailable, which is a concern for domain legitimacy, but the website content and business presence suggest a legitimate operation. Overall, the site scores well on content quality, technical implementation, privacy compliance, and business credibility, with recommendations to enhance security headers and verify domain registration details.

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.

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

  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 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

Atmedia operates in the media sector, focusing on thematic TV advertising in the Czech market. Its business model revolves around media representation and advertising sales, targeting advertisers and media agencies seeking precise audience targeting. The company has built a strong market position as the only independent agency in this niche, with a portfolio of 24 measured TV stations and a client base including major media groups. The website showcases client testimonials and research publications, reinforcing trust and market credibility. The company appears medium-sized with a stable team of professionals. The absence of WHOIS data is a potential risk factor but does not detract from the company's evident market presence and operational maturity.

Security posture

The website employs HTTPS and a cookie consent mechanism compliant with GDPR, indicating a baseline security and privacy awareness. However, no HTTP security headers were detected in the provided data, which could expose the site to certain web-based attacks. The use of reputable third-party scripts like Google Analytics is standard but requires ongoing monitoring for vulnerabilities. No forms with sensitive data collection were found, reducing immediate risk. The lack of visible security policies or incident response contacts suggests room for improvement in transparency and preparedness. Overall, the security posture is moderate but could be strengthened by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Verify and publish domain WHOIS information to improve domain legitimacy and trustworthiness.
  3. Publish a dedicated security policy and incident response contact information to increase transparency and preparedness.
  4. Regularly audit third-party scripts and dependencies for vulnerabilities and update them promptly.
  5. Enhance accessibility features and conduct periodic security assessments to maintain compliance and security posture.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, Owl Carousel for sliders, CountUp.js for animated numbers, and the Foundation framework for responsive design. Cookie consent is managed by the Orejime library, which supports GDPR compliance. Google Analytics is integrated for visitor tracking. The site is mobile-optimized with responsive layouts and clear navigation. Performance is moderate, with no major issues detected in the HTML structure. No CMS or hosting provider information was identified. The site could benefit from improved accessibility features and SEO enhancements such as structured data markup. Security headers are missing, representing a technical risk. Overall, the technical implementation is solid but has room for security and accessibility improvements.
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.
