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

Budget is a globally recognized car rental company operating under the Avis Budget Group umbrella. The website provides vehicle rental services including cars, trucks, and vans, targeting both leisure and business travelers. The brand maintains a strong market position with a professional online presence and comprehensive service offerings. Technically, the website employs modern JavaScript frameworks, integrates multiple analytics and marketing tools, and implements accessibility and privacy compliance features effectively. Security posture is robust with HTTPS enforcement and security headers, though explicit security policies and incident response contacts are not publicly available. The absence of WHOIS data is notable but does not detract from the overall legitimacy of the site given the brand's prominence. Strategic recommendations include publishing detailed security policies and incident response information to enhance trust 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

1 finding 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

      • 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

Budget operates in the transportation sector with an enterprise scale and a global footprint. Its business model revolves around vehicle rentals facilitated through an online platform. The company benefits from the backing of Avis Budget Group, enhancing its market credibility. The website's integration with multiple regional domains indicates a broad geographic reach. Marketing and analytics tools are leveraged to optimize customer engagement and conversion. The absence of direct contact emails or phone numbers on the main site suggests a preference for contact forms and centralized customer service. The company’s digital maturity is evident in its use of advanced tracking and consent management solutions, positioning it well for regulatory compliance and customer trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR requirements. However, the lack of a publicly available security policy or incident response contact limits transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The use of third-party analytics and marketing scripts is managed with user consent, mitigating privacy risks. The missing WHOIS data is a potential concern but likely due to registry policies rather than malicious intent. Overall, the site is secure but could improve by publishing explicit security and incident response information.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and controls.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance transparency around data retention and privacy practices.
  5. Regularly audit third-party scripts for vulnerabilities and compliance.

Technical notes

Notes

The website uses a modern JavaScript-based front-end framework with hydration and accessibility features. It integrates multiple third-party services including Google Tag Manager, Quantum Metric, BounceExchange, and OneTrust for analytics, marketing, and consent management. The site is mobile optimized and SEO friendly with proper meta tags and canonical links. Performance is moderate, with asynchronous loading of scripts to improve speed. No CMS was explicitly detected. Hosting details are not disclosed. The technical implementation supports a professional and scalable online rental platform but could benefit from enhanced documentation of security and compliance features.
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.
