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

Marathon Studio is a Czech creative agency specializing in visual communication, branding, and web design services. The company emphasizes strategic, information-based design solutions aimed at long-term brand development rather than short-term effects. Their service portfolio includes brand strategy, web design, creative campaign ideation, graphic design, consulting, and project management. The website presents a professional and consistent brand image, targeting businesses seeking comprehensive visual identity solutions. Technically, the website is built on the Webflow platform, utilizing modern JavaScript libraries such as jQuery and tracking tools including Google Tag Manager, Facebook Pixel, Hotjar, and LinkedIn Insight Tag. The site is well-optimized for mobile devices, loads quickly, and includes a cookie consent mechanism compliant with GDPR requirements. However, no explicit security headers were detected, and WHOIS data for the domain is unavailable, limiting domain trust verification. From a security perspective, the site enforces HTTPS and implements cookie consent, but lacks visible security policies, incident response contacts, or vulnerability disclosure mechanisms. No critical vulnerabilities or exposed sensitive data were found. The absence of WHOIS data reduces confidence in domain legitimacy, though the professional website content and social media presence support the business's credibility. Overall, Marathon Studio's website demonstrates strong content quality, technical implementation, and privacy compliance, with moderate business credibility due to missing WHOIS information. Strategic recommendations include enhancing security headers, publishing security policies, and improving domain registration transparency to strengthen 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.

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. 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 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

Marathon Studio operates as a small-sized creative agency in the Czech Republic, focusing on visual communication and branding services. Their competitive advantage lies in a strategic, process-driven approach that prioritizes long-term brand value over transient trends. The business model centers on providing end-to-end design and consultancy services, including brand strategy, web design, creative ideation, and project management. The company targets businesses requiring professional branding and digital presence enhancement. Growth indicators include an active portfolio of projects and client testimonials. The agency maintains a presence on major social media platforms, supporting marketing and client engagement. No parent or subsidiary relationships were identified, indicating independent operation.

Security posture

The website exhibits a mature security posture with HTTPS enforced and a GDPR-compliant cookie consent mechanism in place. The use of reputable third-party analytics and marketing tools is balanced with privacy considerations. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No explicit security policies or incident response contacts are published, which could hinder rapid response to security incidents. The lack of WHOIS data limits domain trust verification, posing a potential risk. Overall, the site shows good security hygiene but would benefit from enhanced transparency and additional security controls.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Consider creating and hosting a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Verify and update WHOIS domain registration information to enhance domain legitimacy and trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to ensure they do not introduce vulnerabilities or privacy risks.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern web technologies such as jQuery and asynchronous loading of analytics and marketing scripts (Google Tag Manager, Facebook Pixel, Hotjar, LinkedIn Insight Tag). The site demonstrates fast loading times and excellent mobile optimization. SEO is supported through proper meta tags and Open Graph data. Accessibility features are present but could be further enhanced. Hosting details are not explicitly identified but likely provided by Webflow's infrastructure. The technical implementation is robust with room for improvement in security header deployment and domain registration transparency.
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.
