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

The website emeraldaisle.com serves as a branded promotional platform for National Car Rental's Emerald Club loyalty program, emphasizing speed, choice, and convenience in vehicle rental. It targets business travelers and frequent renters primarily in the U.S. and Canada, offering various vehicle options and membership benefits. The site is professionally designed with multimedia content and clear navigation, reflecting a mature digital presence. Technically, it employs modern JavaScript libraries and tracking tools such as jQuery, Adobe Launch, and Google Tag Manager, with cookie consent managed by OneTrust, indicating compliance with privacy regulations. Security-wise, the site uses HTTPS and avoids exposing sensitive data but lacks explicit security headers and a published security policy, which are areas for improvement. The absence of WHOIS registration data is a notable anomaly; however, the website's branding and external links strongly associate it with the legitimate National Car Rental brand. Overall, the site demonstrates a good balance of business credibility, technical implementation, and privacy compliance, with recommendations to enhance security posture and transparency.

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. 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

  3. 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

    • 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

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

Emerald Club operates as a loyalty and service enhancement program within the transportation sector, specifically car rental. Its market positioning leverages the established National Car Rental brand, focusing on premium customer experience through vehicle choice and counter bypass. The business model centers on membership benefits driving customer retention and upselling premium vehicle options. The website's integration with parent and partner domains, use of advanced tracking and consent tools, and multimedia engagement indicate a strategic approach to customer acquisition and retention. The lack of direct contact details on the site suggests reliance on the parent company's infrastructure for customer service. Growth indicators include multimedia content and mobile app promotion. The partnership ecosystem includes privacy and analytics providers, enhancing compliance and marketing capabilities.

Security posture

The website exhibits a moderate to strong security posture with mandatory HTTPS encryption and no visible exposure of sensitive data. The implementation of OneTrust for cookie consent demonstrates attention to privacy compliance. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosures or incident response contacts are published, which limits transparency and readiness perception. The site does not show signs of vulnerable libraries or insecure forms. Overall, the security maturity is adequate for a marketing site but could be improved by adopting additional headers, publishing security policies, and providing incident response contacts to enhance trust and compliance.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, X-Content-Type-Options, and X-Frame-Options to strengthen security posture.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Enhance accessibility features to meet broader compliance and user experience standards.
  4. Add a terms of service page to clarify user agreements and legal protections.
  5. Investigate and resolve the missing WHOIS registration data to ensure domain legitimacy and trust.

Technical notes

Notes

The website uses a modern front-end technology stack including jQuery, Modernizr, Slick Carousel, and fullPage.js for interactive and responsive user experience. Adobe Launch and Google Tag Manager are employed for tag management and analytics, while OneTrust manages cookie consent, indicating a mature approach to privacy compliance. The site is mobile optimized with responsive design elements and multimedia integration. Performance is moderate, with no major errors or broken elements detected. However, the absence of a detected CMS or hosting provider limits deeper infrastructure insights. SEO optimization is basic, with meta tags present but no structured data like JSON-LD detected. Technical debt appears low, but improvements in accessibility and security headers are recommended to modernize and future-proof the platform.
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.
