Hospitality · Switzerland

Medium risk. 7 critical or high findings in Security headers, GDPR outside view and 1 other check.

Security score

68/100

Risk levelMedium

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

The website tripadvisor.ch is currently inaccessible due to a CAPTCHA challenge page served by a third-party CAPTCHA delivery service, indicating the presence of a Web Application Firewall or bot mitigation system. This prevents extraction of meaningful content, metadata, or business information from the site. Consequently, no privacy policies, contact information, or security policies are detectable in the provided HTML content. The site appears to be related to the hospitality industry, likely a regional version of the Tripadvisor platform, but no direct business details or technical infrastructure information can be confirmed from the data provided. The security posture cannot be fully assessed due to lack of access to actual site content and headers. Overall, the site is protected by security mechanisms that block automated access, which limits the ability to perform a comprehensive analysis.

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

7 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Due to the CAPTCHA challenge blocking access, no detailed business intelligence can be extracted. The domain tripadvisor.ch suggests a regional presence of Tripadvisor, a well-known enterprise in the hospitality and travel review sector. No partner or subsidiary domains were identified in the provided content. The lack of accessible content prevents analysis of market positioning, revenue streams, or customer segments.

Security posture

The presence of a CAPTCHA challenge indicates an active security posture aimed at mitigating automated threats and bots. However, no security headers or SSL configuration details were available for review. No vulnerabilities or incident response contacts were found. The inability to access the site content limits the assessment of compliance with GDPR or other security frameworks. The security posture appears cautious but cannot be fully evaluated.

Recommendations

  1. Provide access to a non-blocked version of the site or crawlable content for comprehensive analysis.
  2. Ensure that privacy and cookie policies are easily accessible and clearly linked on the site.
  3. Implement visible contact information and security policy pages to enhance trust and compliance.
  4. Publish vulnerability disclosure and incident response information to improve security transparency.
  5. Regularly review and update security headers and SSL configurations to maintain strong security posture.
Site observations

Automated reading of the public site. Ratings are indicative.

Generic detected. Page content is a CAPTCHA challenge served via geo.captcha-delivery.com iframe, indicating WAF or bot protection blocking access to actual content. These observations may be incomplete. For a fuller analysis, contact guard@offseq.com.

Technical notes

Notes

The technical data is limited to the presence of CAPTCHA scripts from captcha-delivery.com, indicating use of third-party bot mitigation technology. No CMS, hosting provider, or other technology stack details are visible. Performance, SEO, and accessibility cannot be assessed due to lack of content. The site is likely using HTTPS given the domain, but no explicit SSL configuration details were provided.
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.
