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

Dublin Sightseeing Tours, branded as Dublin Bus, is a well-established tourism service provider in Ireland offering a variety of sightseeing tours including hop-on hop-off buses, ghost tours, day trips, and airport transfers. The company targets tourists visiting Dublin and surrounding areas, leveraging a strong market position supported by positive reviews and a comprehensive online presence. Their business model focuses on direct online ticket sales and partnerships with local attractions. Technically, the website employs standard web technologies including JavaScript and Google Tag Manager with a cookie consent mechanism, indicating a moderate level of digital maturity. However, the absence of WHOIS data and security headers suggests areas for improvement in transparency and security posture. The security evaluation shows basic compliance with privacy regulations but lacks visible incident response or vulnerability disclosure information. Overall, the website is professional, user-friendly, and trustworthy, but could benefit from enhanced security measures and clearer contact information to improve business credibility and compliance.

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

4 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 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

  4. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The company operates in the transportation and hospitality sectors, focusing on tourism services in Dublin, Ireland. It holds a competitive advantage through its long-standing presence (over 35 years) and strong brand recognition, including a top ranking on Tripadvisor. Revenue streams likely include ticket sales for various tours and transportation services. The target customer segment is tourists seeking convenient and comprehensive sightseeing options. Partnerships with related domains such as dodublin.ie and ghostbus.ie expand their service offerings. The website content and structure support a professional image, though the lack of publicly available WHOIS data and direct contact details may limit trust for some users. Growth potential exists through digital marketing and expanding tour options. Strategic observations include the need for improved security transparency and enhanced user engagement features.

Security posture

The current security posture is moderate. The website uses HTTPS and implements a cookie consent banner aligned with GDPR requirements, demonstrating awareness of privacy compliance. However, no security headers were detected in the provided data, and there is no visible security policy or incident response contact information. The use of Google Tag Manager is managed with consent denied by default, which is positive. The absence of WHOIS data and vulnerability disclosure mechanisms reduces transparency and may pose risks. There are no indications of exposed sensitive data or known vulnerabilities in the content analyzed. To improve, the organization should implement security headers, publish a security policy, and provide clear incident response contacts to enhance trust and readiness.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen security posture.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and user trust.
  3. Enhance WHOIS data availability or domain registration transparency to support legitimacy and trustworthiness.
  4. Add explicit company contact information including verified emails and phone numbers on the website to improve business credibility.
  5. Conduct regular security audits of third-party scripts and maintain up-to-date privacy and cookie policies aligned with evolving regulations.

Technical notes

Notes

The website uses standard web technologies including HTML5, CSS, and JavaScript, with Google Tag Manager integrated for analytics and marketing purposes. The site is mobile-optimized with responsive design elements and preloaded fonts for performance. Navigation is clear with a structured menu and accessible ARIA labels. However, no CMS or hosting provider information was detected. Performance is moderate with room for improvement in accessibility features. The absence of security headers and WHOIS data indicates technical debt in security and domain management. Modernization opportunities include implementing security best practices and enhancing accessibility compliance to reduce technical risks impacting business operations.
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.
