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

American Century Investments® is a well-established investment management firm focused on serving institutional investors, professional investors, and wholesale clients. The company provides investment planning, management, and advisory services, with a notable emphasis on funding life-changing medical research. The website reflects a professional and consistent brand image, targeting a specialized financial audience with clear legal disclaimers and compliance with international privacy regulations such as GDPR. Technically, the website employs modern web technologies including JavaScript frameworks like Svelte, jQuery, and Adobe's Dynamic Tag Management for analytics and marketing. The site is mobile-optimized, accessible, and SEO-friendly, with a cookie consent mechanism that aligns with privacy best practices. External integrations include trusted analytics and search services. From a security perspective, the site enforces HTTPS, implements key security headers, and avoids exposing sensitive data. However, it lacks publicly visible security policies, incident response contacts, or vulnerability disclosure mechanisms, which are recommended for organizations in the financial sector. The absence of WHOIS data is a minor concern but does not detract significantly from the site's legitimacy given the professional presentation. Overall, the website demonstrates a strong digital maturity and security posture appropriate for its industry and audience. Strategic recommendations include publishing explicit security and incident response policies, providing clear security contact channels, and adding vulnerability disclosure information to enhance transparency and trust.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  2. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1

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

American Century Investments operates in the finance sector, focusing on institutional and professional investors. Its business model centers on asset management and investment advisory services, with a unique positioning that includes funding medical research initiatives. The company targets a niche market segment, leveraging its reputation and compliance adherence to maintain competitive advantage. The website's content and structure indicate a mature organization with a large operational scale. The absence of direct contact details on the homepage suggests a controlled client engagement approach, typical for institutional financial services. The company appears to maintain a strong partnership ecosystem with third-party analytics and consent providers, supporting its marketing and compliance efforts.

Security posture

The website exhibits a good security posture with enforced HTTPS, comprehensive security headers, and cookie consent mechanisms aligned with GDPR. No vulnerabilities or exposed sensitive information were detected in the HTML content. However, the lack of published security policies, incident response procedures, and vulnerability disclosure channels represents a compliance gap and potential risk area. The absence of a security.txt file or dedicated security contact reduces the organization's transparency and may hinder timely incident reporting. Enhancing these areas would improve the overall security culture and readiness. The domain's WHOIS data unavailability is noted but does not currently indicate malicious activity.

Recommendations

  1. Publish a dedicated security policy and incident response page accessible from the website footer or legal section.
  2. Provide explicit contact information for security incidents, such as a security@ or abuse@ email address.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around data protection officer contact details to comply fully with GDPR requirements.
  5. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern technology stack including Svelte for UI components, jQuery for legacy support, Adobe DTM for tag management, and OneTrust for cookie consent management. It loads fonts from Google Fonts and uses Plyr for media playback. The site is well-structured with proper meta tags for SEO and social media sharing (Open Graph and Twitter cards). Performance is moderate, with asynchronous loading of scripts to optimize page load times. Accessibility features are present, including focus outlines and ARIA attributes. Hosting provider details are not explicitly identified from the HTML content. Overall, the technical implementation supports a professional and compliant digital presence.
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.
