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

TSO AG is a Swiss-based company specializing in digital transformation services for the tourism sector, including associations, destinations, transport companies, and hotels. Their business model revolves around providing shared-service digital solutions to automate processes and improve performance. The website reflects a professional and consistent brand image with a clear focus on tourism digitalization. Technically, the site uses Contao CMS, integrates modern analytics and consent management tools like Cookiebot and Google Tag Manager, and employs HTTPS with good security practices. However, explicit contact information and security policies are not prominently available, which could be improved. The security posture is solid with no visible vulnerabilities, but the absence of a security.txt or incident response information is a gap. Overall, the site is trustworthy, compliant with GDPR via Cookiebot, and well-positioned in its niche.

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

3 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 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

  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
      • 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

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

TSO AG targets tourism industry stakeholders with digital tools and services, positioning itself as a niche provider in tourism digitalization. Their portfolio includes partnerships with related digital service providers like Digital.Fitness and TourismusWeb. The company leverages modern web technologies and analytics to optimize user experience and marketing effectiveness. The business model likely includes SaaS or shared-service offerings tailored to tourism organizations. The lack of direct contact details on the main site suggests a focus on B2B relationships possibly managed through other channels. The company appears medium-sized with a professional online presence and a clear market focus.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of security headers, and a robust cookie consent mechanism via Cookiebot. Analytics and marketing scripts respect user consent, indicating GDPR compliance efforts. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of published security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency. Adding a security.txt and explicit security documentation would enhance trust and readiness. Overall, the security posture is good but could be improved with formalized policies and contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page with clear contact information.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosures.
  3. Enhance security headers by adding HSTS, X-Frame-Options, and Content-Security-Policy if not fully implemented.
  4. Provide clear company contact details including emails and phone numbers on the website for better business credibility.
  5. Regularly audit third-party scripts and update CMS/plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on Contao Open Source CMS with jQuery and integrates Google Tag Manager, Cookiebot for consent management, and Plausible Analytics for privacy-friendly tracking. The site uses modern fonts from Google Fonts and loads scripts asynchronously to optimize performance. The design is responsive and mobile-optimized with good SEO meta tags and Open Graph data. Performance is moderate, with potential improvements in loading speed by optimizing images and scripts. Accessibility is basic but could be enhanced with ARIA roles and better keyboard navigation support. Overall, the technical infrastructure is solid and supports the business goals effectively.
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.
