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

The website www.antstudio.cz represents (ant), a full-service digital agency based in the Czech Republic. The company offers a broad range of services including branding, consulting, creative campaigns, performance marketing, web and e-commerce development, and training workshops. The site demonstrates a strong market position with professional design, clear service offerings, and client testimonials, indicating a mature and reputable business. Technically, the website is built on modern frameworks such as Next.js and React, optimized for performance and mobile devices, with good SEO and accessibility features.

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  2. 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

The agency targets businesses seeking comprehensive digital marketing and branding solutions, leveraging a full-service model that integrates strategy, creative, and technical execution. Their portfolio includes notable clients and case studies, enhancing their competitive advantage. The business model is service-oriented with revenue streams from consulting, campaign management, web development, and training. The company appears medium-sized with consistent branding and a professional online presence. No parent or subsidiary companies are identified. The lack of explicit contact details on the site may limit direct client engagement but is offset by strong content and testimonials.

Security posture

The website employs HTTPS and modern web technologies, reducing risks related to data interception and outdated software. However, the absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is provided, which could hinder timely security issue reporting and resolution. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The security score is good but could be improved by implementing recommended headers and formal security policies.

Recommendations

  1. Implement and publicly link comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Provide clear contact information including emails and phone numbers for client and security incident communication.
  4. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built using Next.js and React, indicating a modern and scalable infrastructure. It uses optimized WebP images and SVG icons for performance and visual quality. The site is mobile-optimized with responsive design and accessibility considerations. No CMS is explicitly detected, suggesting a custom or headless approach. Performance is fast with preloading of fonts and images. The technical implementation is robust, though adding security headers and formal privacy mechanisms would enhance the overall technical maturity.
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.
