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

Media Heroes s.r.o. is a Czech-based digital agency specializing in web development and internet marketing services. The company positions itself as a provider that saves clients time and helps them navigate the complexities of internet marketing. The website is professionally designed, targeting businesses and individuals in the Czech Republic seeking digital marketing and web creation services. The content is primarily in Czech and reflects a small to medium-sized agency with a local market focus. Technically, the website employs a modern technology stack including jQuery, Google Fonts, Google Analytics, Facebook Pixel, Smartlook, Leady tracking, and Cookiebot for cookie consent management. The site is mobile optimized and includes SEO best practices such as meta tags and Open Graph data. However, no CMS or hosting provider information is explicitly detected. Performance is moderate, with room for improvement in accessibility and security headers. From a security perspective, the site uses HTTPS and anonymizes IP addresses in Google Analytics, indicating some attention to privacy. Cookie consent is implemented comprehensively via Cookiebot, categorizing cookies by purpose and provider. However, no WHOIS data is available, which reduces transparency and trustworthiness. No explicit privacy policy or terms of service pages were found in the provided content, and no security or incident response policies are visible. The site uses multiple third-party marketing and analytics tools, which increases tracking but is managed with user consent. Overall, the website presents a legitimate and professional digital agency with good privacy compliance and marketing transparency. The lack of WHOIS data and explicit privacy/security policies are areas for improvement. Strategic recommendations include enhancing security headers, publishing clear privacy and security policies, and providing contact information for incident response to increase 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

4 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

Media Heroes operates as a small digital agency focused on web development and internet marketing within the Czech Republic. Their business model centers on service provision to local clients, emphasizing time-saving and marketing expertise. The company leverages partnerships with major advertising and analytics platforms such as Google and Facebook, integrating their tools for marketing effectiveness. The absence of WHOIS data and limited public business information suggest a need for greater transparency. The company appears to maintain a moderate market position with potential for growth by enhancing trust signals and compliance documentation.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and anonymized IP tracking in analytics. Cookie consent is managed via Cookiebot, reflecting GDPR compliance efforts. However, the absence of security headers and explicit security policies indicates gaps in defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the content. The lack of incident response contact information and security.txt file reduces readiness for security incidents. Overall, the security posture is adequate for a small digital agency but would benefit from implementing recommended security best practices and transparency measures.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy and terms of service pages clearly accessible from the website footer or main navigation.
  3. Establish and publicize an incident response contact channel, such as security@ or abuse@ email addresses.
  4. Regularly audit and update third-party scripts and tracking tools to minimize vulnerabilities and ensure compliance.
  5. Increase transparency by providing WHOIS data or domain registration information and company contact details to build trust with visitors.

Technical notes

Notes

The website uses a combination of classic web technologies including jQuery and Fancybox, integrated with modern marketing and analytics tools such as Google Analytics, Facebook Pixel, Smartlook, and Leady. Cookiebot is used for cookie consent management, indicating a focus on privacy compliance. The site loads Google Fonts for typography and uses canonical URLs for SEO. No CMS or hosting provider is explicitly identified. Performance is moderate with good mobile optimization. Accessibility features are basic and could be improved. The site lacks visible security headers, which is a technical risk. Overall, the technical infrastructure is solid for a small agency but could be modernized and hardened for better security and performance.
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.
