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

Impression Media s.r.o. is a well-established Czech internet media agency specializing in advertising representation and sales. The company claims to be the largest media representative on the Czech market, serving over 7 million real users monthly across approximately 150 internet servers. Their key services include advertising packages, standard and non-standard ad formats, video advertising, PR articles, and programmatic buying. The website reflects a professional business presence with clear branding and trust indicators such as Google Partner and Sklik Verified Agency badges. Technically, the website employs a modern technology stack including jQuery, Bootstrap, Google Tag Manager, and Cookiebot for consent management. The site is mobile optimized and presents good SEO and accessibility basics. Security measures include HTTPS enforcement and Google reCAPTCHA on the contact form, though security headers are not detected, and no explicit security or privacy policies are published. The security posture is moderate with room for improvement in published policies and security headers. The absence of WHOIS data reduces domain trustworthiness and raises questions about domain registration transparency. However, the website content and business information appear legitimate and consistent with a professional media agency. Overall, the website is safe, professional, and functional, but would benefit from enhanced privacy compliance, security policy publication, and WHOIS transparency to improve trust and compliance posture.

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

    • High

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

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

Impression Media operates as a key player in the Czech internet advertising market, leveraging a portfolio of popular websites and a large user base to attract advertisers. Their business model focuses on media representation and advertising sales, targeting both internet server owners and advertisers. The company maintains partnerships with major advertising platforms like Google Ads and Sklik, enhancing their market reach. The presence of multiple sales teams including telesales indicates a diversified revenue approach. The company’s growth is supported by strong user engagement metrics and a broad portfolio of represented servers. However, the lack of publicly available WHOIS data and privacy policies may pose challenges in regulatory compliance and trust-building with new clients.

Security posture

The website demonstrates a baseline security posture with HTTPS enabled and Google reCAPTCHA protecting the contact form against spam and abuse. Cookie consent management is implemented via Cookiebot, indicating awareness of privacy regulations. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap that could expose the site to certain web-based attacks. No published security policies or incident response contacts are found, limiting transparency and preparedness for security incidents. The missing WHOIS data also reduces domain trust and complicates attribution. Overall, the security maturity is moderate but could be significantly improved with better header implementation, policy publication, and vulnerability disclosure mechanisms.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Provide a published security policy and incident response contact information to enhance transparency and preparedness.
  4. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website uses a modern and widely supported technology stack including jQuery, Bootstrap for responsive design, and Google Tag Manager for analytics and marketing tag management. Cookiebot is integrated for cookie consent management, and Google reCAPTCHA protects the contact form. The site loads multiple CSS and JS assets efficiently and is mobile optimized with good navigation clarity. However, no CMS is detected, suggesting a custom or static site build. Performance is moderate with no obvious blocking scripts. Accessibility is basic but could be improved with ARIA roles and semantic HTML enhancements. SEO is supported by proper meta tags and structured navigation. Overall, the technical infrastructure is solid but could benefit from enhanced security headers and performance tuning.
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.
