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

Tudio is a newly established Czech innovation and communication agency founded in 2023. The company offers services in innovation consulting, strategic development, marketing, branding, digitalization, and social media management, targeting organizations seeking to enhance resilience through innovation and marketing. The website reflects a professional and consistent brand image with clear contact information and subsidiary details. Technically, the site uses modern web technologies including Google Tag Manager, Google Fonts, Font Awesome, and is built on the proprietary Websy platform hosted by WEDOS. Performance and mobile optimization are moderate to good, though accessibility and SEO could be improved. Security posture is adequate with HTTPS implied and cookie consent implemented, but lacks explicit security headers and published security policies. No privacy policy or terms of service are present, representing compliance gaps. Overall, the domain registration data aligns well with the business information, supporting legitimacy. Recommendations include publishing privacy and security policies, enhancing security headers, and improving accessibility and SEO.

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.

    • 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
      • 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. 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.

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  4. 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"

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

Business profile

Tudio operates as a small, Czech-based innovation and marketing agency with a clear focus on delivering value through strategic and creative services. Its business model centers on consulting and digital communication services for commercial and public sectors. The company maintains a subsidiary, Little Tudio s.r.o., indicating some organizational structure. Market positioning is that of an innovative and strategic partner in the Czech market. The website content and contact details support a credible and professional presence, though the lack of privacy and terms policies may affect trust with privacy-conscious clients. The company leverages modern marketing tools and tracking but does not appear to engage in extensive advertising or affiliate programs. Growth potential is indicated by the recent founding date and clear service offerings.

Security posture

The website demonstrates a basic to moderate security posture. HTTPS is used, and a cookie consent mechanism is implemented, supporting GDPR compliance efforts. However, no explicit security headers (such as Content Security Policy, HSTS, or X-Frame-Options) were detected, which could expose the site to certain web-based attacks. There is no published security or incident response policy, nor a vulnerability disclosure or security.txt file, limiting transparency and preparedness for security incidents. No forms or user input fields were found that might require additional security controls. The use of third-party scripts like Google Tag Manager introduces some risk but is common practice. Overall, the security posture is adequate for a small business but could be improved with standard best practices and policy publication.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and user trust.
  2. Implement and configure security headers such as Content Security Policy, HSTS, and X-Frame-Options.
  3. Develop and publish an incident response policy and provide security contact information.
  4. Enhance website accessibility and SEO to improve user experience and search visibility.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the proprietary Websy platform and hosted by WEDOS, a Czech hosting provider. It uses modern web technologies including Google Fonts, Font Awesome icons, and Google Tag Manager for analytics and marketing. The HTML structure is valid and includes responsive meta tags for mobile optimization. Performance is moderate, with no major issues detected in the provided content. However, accessibility features are basic and could be improved. SEO is basic with some meta tags present but no structured data or extensive metadata. No forms or complex interactive elements were detected, reducing attack surface but also limiting user engagement features. The site lacks explicit security headers, which is a technical risk. Overall, the technical implementation is solid for a small business website but has room for modernization and security enhancements.
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.
