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

Big Bus Tours Ltd operates as a leading global sightseeing bus tour provider, specializing in hop-on hop-off tours across major cities such as London, New York, and Paris. The company holds a strong market position as the largest operator of open-top sightseeing bus tours with over 30 years of service. Their business model focuses on tourism and travel services, offering additional experiences beyond bus tours to enhance customer engagement. The website reflects a professional and consistent brand presence targeting tourists worldwide. Technically, the website is built on Magento 2, leveraging modern web technologies including RequireJS, Google Tag Manager, and various marketing and analytics tools such as MoEngage and New Relic. Hosting and DNS services are provided by Cloudflare, ensuring global content delivery. While the site is mobile-optimized and SEO-friendly, performance metrics are not explicitly available. Accessibility is basic but functional. From a security perspective, the site implements several important HTTP security headers and a comprehensive Content Security Policy. However, a critical vulnerability is the absence of a valid SSL certificate and lack of TLS protocol support, severely impacting the security posture. This exposes users to risks and undermines trust. Privacy compliance is addressed with clear privacy and cookie policies, including consent mechanisms, but no explicit security or incident response policies are found. Overall, the website is functional and business credible but requires urgent security improvements to protect user data and maintain trust. Strategic recommendations include obtaining a valid SSL certificate, enabling modern TLS protocols, enhancing HSTS policies, and improving incident response readiness.

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.

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

Big Bus Tours Ltd holds a dominant position in the sightseeing transportation sector, leveraging a large network and brand recognition built over three decades. Their competitive advantage lies in their extensive city coverage and diversified offerings beyond bus tours, such as desert safaris and wine tours. Revenue streams primarily come from ticket sales and ancillary experiences. The company targets international tourists seeking convenient and iconic city tours. Partnerships with major payment processors and marketing platforms support their operations. The multilingual website and social media presence indicate a global customer focus and digital maturity. Growth potential exists through expanding alternative experiences and enhancing digital engagement.

Security posture

The current security maturity level is low due to the lack of a valid SSL certificate and disabled TLS protocols, which are critical for secure communications. While security headers and CSP are well implemented, the absence of HTTPS undermines these protections. No incident response or vulnerability disclosure policies are publicly available, indicating gaps in security governance. Data protection practices appear basic but compliant with GDPR through privacy and cookie policies. The extensive use of third-party analytics and marketing tools increases the attack surface and requires careful management. Overall, the security culture needs strengthening with prioritized remediation of critical vulnerabilities and formalized policies.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate immediately to enable HTTPS and protect user data.
  2. Enable TLS 1.2 or higher protocols and disable insecure legacy protocols to improve encryption standards.
  3. Enhance HSTS header with includeSubDomains and preload directives to enforce strict transport security.
  4. Develop and publish formal security policies including incident response and vulnerability disclosure.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve compliance.
Technical notes

Notes

The website is built on a robust Magento 2 platform with modern JavaScript frameworks and extensive use of third-party integrations for payments, analytics, and marketing. Hosting is managed via Cloudflare providing CDN and DNS services. The site is mobile-optimized and SEO-friendly with multilingual support. However, the absence of SSL/TLS support is a major technical deficiency. Performance data is unavailable, but the use of caching and CDN suggests moderate to good performance. Technical debt appears manageable but security technical debt is high due to missing encryption and incomplete security policies.
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.
