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.

    • 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

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

DiscoverCars.com operates in the transportation sector, specifically focusing on car rental services. Its business model revolves around aggregating car rental offers from numerous suppliers and providing a comparison and booking interface to end users. The company leverages partnerships with global suppliers and integrates affiliate programs to expand reach. The platform's multilingual support and extensive location coverage position it competitively in the global travel market. Revenue streams likely include commissions from bookings and affiliate marketing. The presence of mobile applications indicates investment in multi-channel customer engagement. Strategic observations suggest a focus on customer convenience, competitive pricing, and trust-building through transparent policies and support.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and integration of Google reCAPTCHA Enterprise to mitigate automated abuse. Cookie consent mechanisms and privacy policies align with GDPR compliance, reflecting attention to data protection. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure programs indicates areas for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The security score is strong but could be enhanced by publishing detailed security governance documents and establishing formal incident response channels.

Recommendations

  1. Publish a dedicated security policy page outlining security governance and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide clear incident response contact information for security issues.
  4. Consider publishing Data Protection Officer contact details to enhance GDPR transparency.
  5. Regularly review and audit third-party scripts and integrations for security risks.

Technical notes

Notes

It uses Mapbox for mapping services and integrates with multiple advertising and tracking platforms. The site is well-optimized for performance and mobile responsiveness, with good SEO metadata and accessibility features. Hosting details are not explicitly identified, but the presence of strong security headers and HTTPS indicates a professionally managed infrastructure. Opportunities exist to improve technical documentation and transparency around CMS and hosting providers. Overall, the technical implementation supports a high-quality user experience and operational reliability.
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.
