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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. GDPR outside view

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

    • 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

  3. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain staging.redbus.sg points to unregistered service rb-intl-staging-web-elb-59054641.ap-southeast-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

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

  • Security headers: did not complete in this scan.
  • 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

redBus Singapore operates in the transportation sector, focusing on online bus and ferry ticket sales. Its competitive advantage lies in extensive operator partnerships, a broad route network, and a seamless digital booking experience. The business model is commission and service fee-based, supported by promotional campaigns (redDeals) to attract price-sensitive customers. The platform targets both local commuters and regional travelers, with a strong presence in Singapore and neighboring countries. Growth indicators include a large user base (36 million+ globally), high daily booking volumes, and mobile app adoption. The company benefits from its parent Ibibo Group's resources and regional network, enabling cross-market synergies. The partnership ecosystem includes multiple regional redBus domains and bus operators, enhancing market reach and service diversity.

Security posture

The security posture of redBus Singapore is solid, with HTTPS enforced and integration of advanced monitoring tools like New Relic and Riskified for fraud detection. The site avoids exposing sensitive data in its HTML and uses secure payment gateways supporting multiple payment methods. However, explicit security policies, vulnerability disclosure programs, and incident response contacts are not publicly available, representing a compliance gap. The use of third-party marketing and analytics scripts introduces a moderate tracking footprint, which is managed with cookie consent mechanisms. No immediate vulnerabilities or security misconfigurations were identified in the analyzed content. The security score is good but could be improved by formalizing security governance documentation and enhancing transparency.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and disclose a vulnerability disclosure or bug bounty program.
  3. Ensure all recommended security headers (CSP, X-Frame-Options, etc.) are configured and documented.
  4. Enhance accessibility features to meet WCAG standards for broader user inclusion.
  5. Regularly audit third-party scripts to minimize security and privacy risks.

Technical notes

Notes

The website is built using modern JavaScript frameworks likely React, with SPA architecture and extensive use of JSON-LD structured data for SEO. It leverages third-party services for analytics (Google Analytics via GTM), performance monitoring (New Relic), and marketing (Criteo, Riskified). Hosting is via a CDN (Akamai), ensuring fast global delivery. The site is mobile-optimized and uses responsive design. Performance is fast with preconnect and preload hints for critical resources.

Overall, the technical infrastructure supports a scalable and reliable user experience aligned with industry best practices.
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.
