Security score

80/100

Risk levelLow

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

The Hertz Corporation operates a comprehensive vehicle rental service platform, targeting both general consumers and business clients primarily in Finland as evidenced by the Finnish language content and localized services. The website offers a range of rental vehicles including passenger cars, vans, minibuses, and leasing options, supported by a loyalty program called Gold Plus Rewards. The company maintains a strong market position as a leading global car rental provider with a professional and consistent brand presence. Technically, the website employs a modern technology stack including RequireJS, Google Tag Manager, Google Analytics, Google reCAPTCHA Enterprise, Stripe.js for payments, and MapQuest for mapping services. The site is mobile optimized, SEO friendly, and uses secure HTTPS connections with appropriate security headers, indicating a mature digital infrastructure. From a security perspective, the site demonstrates good practices such as enforcing HTTPS, implementing reCAPTCHA to prevent abuse, and providing cookie consent mechanisms compliant with GDPR. However, there is a lack of visible security policy or incident response contact information, and no vulnerability disclosure or security.txt file was found, which could be improved to enhance transparency and trust. Overall, the website is legitimate, professionally managed, and secure with a high trustworthiness rating. The absence of WHOIS data is likely due to privacy protection services, which is common for large enterprises. The site is safe for general audiences with no adult or explicit content detected.

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

2 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 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. 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

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

Hertz operates in the transportation sector with a focus on vehicle rentals and leasing. The business model revolves around providing a wide range of rental vehicles to consumers and businesses, supported by loyalty programs and regional localization. The company leverages partnerships with payment processors and analytics providers to optimize customer experience and marketing. The Finnish localized site indicates a global footprint with tailored regional offerings. The absence of direct contact information on this page suggests centralized customer service channels elsewhere. The company’s brand consistency and comprehensive service offerings position it strongly in the competitive car rental market.

Security posture

The website exhibits a mature security posture with HTTPS enforced, modern security headers, and integration of Google reCAPTCHA Enterprise to mitigate automated abuse. Cookie consent mechanisms align with GDPR requirements, enhancing privacy compliance. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a gap in transparency and readiness communication. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security posture is strong but could benefit from enhanced communication of security governance and incident response capabilities.

Recommendations

  1. Publish a dedicated security policy page including incident response procedures and contact information.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance accessibility features to meet higher compliance standards.
  4. Provide clear and accessible company contact information on the website.
  5. Regularly review and audit third-party scripts and dependencies for security vulnerabilities.

Technical notes

Notes

The website uses a modular JavaScript architecture with RequireJS, integrating multiple third-party services such as Google Tag Manager, Google Analytics, Stripe for payments, and MapQuest for location services. The site is served over HTTPS with appropriate security headers, indicating a secure hosting environment. Performance is moderate with asynchronous loading of scripts and deferred CSS loading to optimize rendering. Mobile optimization is good, with responsive design and font loading strategies. The site lacks a detectable CMS, suggesting a custom or proprietary platform. Opportunities exist to improve accessibility and to document technical and security policies more explicitly.
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.
