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

3 findings rated critical or high. Fix these first.

  1. 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

  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

      • 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

Discover Financial Services maintains a competitive advantage through a diversified product portfolio including credit cards with rewards, online banking, and various loan products. Their business model focuses on consumer financial services with revenue streams from credit card interest, loan origination, and banking services. The company targets a broad consumer base, including students, individuals seeking debt consolidation, and general banking customers. Strategic partnerships and subsidiaries such as Diners Club International and Discover Global Network expand their market reach. The website's integration with multiple analytics and marketing platforms indicates a mature digital marketing strategy aimed at customer acquisition and retention.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and secure form handling. The use of multiple tracking and analytics scripts is balanced with privacy compliance measures. However, the absence of a publicly available security policy or incident response contact limits transparency. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from publishing a security.txt file and enhancing user awareness of data protection practices. Overall, the security maturity is high, suitable for a financial services provider handling sensitive customer data.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and incident response procedures.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Regularly audit and update third-party scripts to mitigate potential security risks.
  4. Enhance transparency on data retention and user data handling policies.
  5. Maintain and improve accessibility and mobile optimization to ensure compliance with evolving standards.

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.
