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

Tallink Grupp operates a comprehensive ferry and cruise service primarily in the Baltic Sea region, connecting Estonia with Finland, Sweden, and other destinations. The website offers ticket booking, hotel accommodations, cargo services, and a loyalty program, targeting leisure and business travelers. The digital platform is built on modern web technologies including Next.js and React, ensuring a responsive and user-friendly experience across devices. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms implemented, although explicit security policies and incident response contacts are not publicly available. The absence of WHOIS data for the domain introduces some uncertainty, but the professional presentation and consistent branding support the legitimacy of the business. Overall, the website demonstrates a mature digital presence with room for improvement in transparency around security and incident handling.

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

6 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 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

    • High

      Third-party services without privacy policy

      Detected services: Facebook, YouTube, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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

Tallink holds a leading position in the Baltic transportation and hospitality market, leveraging integrated services across travel, accommodation, retail, and cargo. Their business model focuses on providing seamless travel experiences with value-added services such as loyalty programs and e-commerce. The company targets a broad audience including families, business groups, and cruise enthusiasts. The website's multilingual support and extensive content reflect a strategic approach to market reach and customer engagement. Partnerships and related domains indicate a well-structured ecosystem supporting various aspects of the business. Growth indicators include special event cruises and promotional offers. The lack of visible direct contact information on the main site suggests a preference for centralized customer service channels.

Security posture

The website employs robust security measures including HTTPS with strong SSL configuration and multiple security headers to protect user data and prevent common web attacks. The use of a custom SSO system and iframe for authentication enhances security for user login processes. Cookie consent and privacy policies align with GDPR requirements, indicating compliance with data protection regulations. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency and may hinder rapid response to security incidents. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Recommendations include publishing security documentation and providing clear security contact channels to improve trust and incident management readiness.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear and accessible contact information for security incidents and abuse reports.
  4. Regularly review and audit third-party scripts and libraries for security vulnerabilities.
  5. Enhance WHOIS data transparency or ensure domain registration details are publicly accessible to improve trust.

Notes

The website is built using modern web technologies, primarily Next.js and React, enabling server-side rendering and optimized performance.

The site includes a custom single sign-on system embedded via iframe, indicating advanced user management capabilities. CSS is modular and well-structured, supporting responsive design and accessibility. Performance is fast with preloading and prefetching of critical resources. No CMS was explicitly detected, suggesting a custom or headless CMS solution. Hosting provider details are not disclosed. Overall, the technical infrastructure supports a high-quality user experience with scalability and security considerations.
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.
