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. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

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

    • 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

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

FlixBus India leverages its global brand strength to capture a large share of the Indian intercity bus travel market. Its business model centers on online ticket sales and providing value-added services such as sleeper buses and real-time tracking. The company benefits from a broad route network covering major Indian cities and connections, supported by a mobile app that facilitates booking and trip management. Partnerships with local operators and a focus on customer satisfaction enhance its competitive advantage. The presence of multiple language options and extensive service information indicates a mature digital presence. Revenue streams likely include ticket sales, seat reservations, and ancillary services. The company maintains active social media channels to engage customers and promote offers.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and integration of consent management tools. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program represents a gap in transparency and readiness. The use of multiple third-party scripts and ad networks introduces potential risk vectors that require ongoing monitoring. Overall, the security measures are robust for a commercial travel platform but could be enhanced by publishing formal security documentation and providing dedicated security contact channels.

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. Add explicit security contact email addresses for reporting incidents or abuse.
  4. Regularly audit and update third-party scripts to mitigate supply chain risks.
  5. Optimize website performance further to improve user experience and reduce load times.

Technical notes

Notes

The website is built using modern front-end technologies including React and CSS modules, with a Drupal CMS backend inferred from asset paths. It uses Amazon Cloudfront CDN for content delivery, enhancing performance and availability. Analytics and tracking are implemented via Google Tag Manager and Datadog RUM, with user consent managed by Usercentrics. The site is mobile responsive and accessible, with good SEO metadata and Open Graph tags. Some scripts are asynchronously loaded to improve page load speed. The technical infrastructure is solid, though performance is moderate and could benefit from further optimization. No critical technical debt or outdated technologies were identified.
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.
