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

Alamo Rent a Car, a brand under Enterprise Holdings, Inc., operates a comprehensive car rental service platform targeting travelers across North America, Latin America, the Caribbean, Europe, and parts of Asia-Pacific and the Middle East. The website offers reservation services, loyalty programs, and promotional deals, positioning itself as a large enterprise in the transportation sector with a strong market presence. The digital infrastructure is built on modern technologies including React and Adobe Experience Manager, supported by robust analytics and marketing tools such as Adobe Target and Google Analytics. Privacy and cookie compliance are well addressed with OneTrust integration, reflecting a mature approach to user data protection. Security posture is solid with HTTPS enforcement and use of ReCaptcha, though explicit security headers and incident response contacts could be improved. The absence of WHOIS data is notable but likely due to registry or query limitations rather than malicious intent. Overall, the website demonstrates good professionalism, trustworthiness, and technical maturity.

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. 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 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';…

  2. 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Alamo's market positioning as a major car rental provider is reinforced by its parent company Enterprise Holdings. The business model focuses on direct online reservations, loyalty incentives via Alamo Insiders, and value-driven promotions. The target audience includes leisure and business travelers seeking convenient and affordable car rentals globally. The partnership ecosystem includes airline and hotel partners, enhancing customer value. The website's content and navigation support a seamless user experience, while the technical stack supports scalability and performance. Growth indicators include active promotional campaigns and mobile app integration. Strategic observations suggest continued investment in digital marketing and customer experience to maintain competitive advantage.

Security posture

The website exhibits a mature security posture with mandatory HTTPS, integration of ReCaptcha for bot mitigation, and cookie consent management via OneTrust. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options are not clearly present in the analyzed content, representing an area for enhancement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security policy or incident response contact limits transparency in security governance. Compliance with GDPR is indicated through privacy policies and consent mechanisms. Overall, the security maturity is good but could benefit from improved header configurations and public security disclosures.

Recommendations

  1. Implement and verify security headers including X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  2. Publish a dedicated security policy and provide clear incident response contact information to improve transparency and trust.
  3. Conduct regular audits of third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  4. Enhance accessibility features to meet WCAG standards for broader user inclusivity.
  5. Consider implementing a security.txt file to facilitate responsible vulnerability disclosure.

Technical notes

Notes

The website leverages a modern technology stack including React for frontend components and Adobe Experience Manager as the CMS platform, enabling dynamic content delivery and personalization. Integration with Adobe Target and Google Analytics supports advanced marketing and analytics capabilities. The use of OneTrust ensures compliance with privacy regulations. Hosting appears to be supported by Akamai CDN, enhancing performance and availability. The site demonstrates good mobile optimization and SEO practices. Performance is moderate, with opportunities to optimize load times further. Technical debt appears minimal, but continuous monitoring of third-party scripts and dependencies is recommended to maintain security and performance.
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.
