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

S2 STUDIO s.r.o. is a well-established Czech digital agency founded in 2003, specializing in web design, e-commerce solutions, online marketing, graphic design, and custom software development. The company positions itself as a comprehensive service provider offering end-to-end digital solutions to businesses, supported by multiple certifications including Google Partner and ISO 9001. The website demonstrates a professional and modern digital presence with rich multimedia content and clear navigation. Technically, the site uses a variety of modern JavaScript libraries and tracking tools, with good mobile optimization and SEO practices. Security posture is solid with HTTPS and cookie consent mechanisms, though there is room for improvement in security headers and explicit incident response policies. The absence of WHOIS data limits domain trust verification but does not detract from the overall legitimacy indicated by business content and certifications.

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

  2. Network security

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

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 · found on this site
  • 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

The company targets businesses seeking integrated digital marketing and web development services, leveraging a broad portfolio that includes graphic design and advertising production. Their business model focuses on providing comprehensive digital solutions under one roof, reducing client overhead. The presence of numerous client references and certifications suggests a strong market position in the Czech Republic. The company maintains active social media engagement and uses advanced marketing tools for client campaigns. Growth indicators include a diverse client base and strategic partnerships. However, the lack of publicly available domain registration data is a minor concern for external trust verification.

Security posture

The website enforces HTTPS and employs cookie consent with granular user controls, indicating compliance with GDPR. Use of Google reCAPTCHA on forms adds protection against automated abuse. However, no explicit security headers were detected, and there is no published security or incident response policy, which are areas for enhancement. No vulnerabilities or exposed sensitive data were found in the HTML content. The security score is good but could be improved by implementing additional HTTP security headers and publishing clear security policies. Incident response readiness and DPO contact information are not publicly available, which may impact compliance with certain regulations.

Recommendations

  1. Implement comprehensive HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency and compliance.
  3. Regularly audit third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience.
  5. Consider publishing terms of service and data protection officer contact details to strengthen legal compliance and user trust.

Technical notes

Notes

The website uses a modern tech stack including jQuery 3.6.0, Slick Slider, Alertify.js, and LazySizes for performance optimization. It loads Google Fonts and integrates Google Analytics and Facebook Pixel for analytics and marketing. The site is mobile optimized with responsive design and lazy loading of images. Performance is moderate with deferred CSS loading and asynchronous script loading. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site could benefit from enhanced accessibility features and additional SEO optimizations. Overall, the technical implementation supports a professional and user-friendly digital presence.
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.
