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

      • 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

Avis maintains a leading position in the car rental market, supported by its parent company Avis Budget Group and subsidiaries like Budget and Zipcar. The business model focuses on vehicle rentals with an emphasis on online reservations and customer loyalty. The company targets a broad audience including individual travelers and corporate clients. Its digital ecosystem integrates multiple third-party analytics and marketing platforms to optimize user engagement and conversion. The brand's global footprint and enterprise scale justify privacy protections in domain registration. Strategic partnerships and a diversified brand portfolio enhance its competitive advantage and market reach.

Security posture

The website exhibits a mature security posture with enforced HTTPS, modern security headers, and cookie consent compliance. However, the absence of a publicly available security policy or incident response contact reduces transparency. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of multiple third-party scripts necessitates ongoing security audits to mitigate supply chain risks. The lack of a vulnerability disclosure program or security.txt file is a gap in responsible security practices. Overall, the security maturity is good but could be improved by publishing explicit security governance documents and enhancing vulnerability reporting channels.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Implement and publicize a vulnerability disclosure program with clear reporting channels.
  3. Add a security.txt file at the root domain to facilitate responsible vulnerability reporting.
  4. Regularly audit and update third-party scripts to minimize supply chain vulnerabilities.
  5. Enhance transparency by providing contact information for the Data Protection Officer or security team.

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.
