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

SEI is a leading provider of technology and investment solutions tailored for the financial services industry. The company offers enterprise platform solutions and outsourced operations that address complex business challenges faced by asset managers, banks, wealth managers, financial advisors, institutional investors, and individual clients. SEI positions itself as a trusted partner enabling confident decision-making and growth within the financial sector. The website reflects a mature digital presence with a professional design, clear navigation, and comprehensive content that aligns with its market positioning. Technically, the website is built on Drupal 10, leveraging modern web technologies including Google Tag Manager for analytics and OneTrust for cookie consent management, indicating a strong commitment to privacy compliance. The use of Akamai CDN and Brightcove video player further enhances performance and user experience. The site is mobile-optimized and accessible, with SEO best practices implemented. From a security perspective, SEI employs HTTPS with strong SSL configurations and security headers, demonstrating adherence to best practices. However, explicit incident response and vulnerability disclosure policies are not prominently published, which could be improved to enhance transparency and trust. The WHOIS data is unavailable, likely due to privacy protection, which is common and justified for a financial services firm. Overall, SEI's website presents a secure, professional, and trustworthy digital front that supports its business objectives. Strategic recommendations include publishing clear security policies, providing direct security contact channels, and maintaining updated domain registration information to further strengthen trust and compliance.

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 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
    • 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

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

SEI operates in the finance and technology sectors, focusing on delivering integrated technology and investment management solutions. Its business model revolves around providing customizable platforms and outsourced operations to a diverse client base including asset managers, banks, wealth managers, financial advisors, institutional investors, and individuals. The company leverages certifications such as ISO 27001 to demonstrate security commitment. SEI's market position is that of an established enterprise with a strong brand and consistent digital presence. The website content and structure indicate a focus on enterprise clients and compliance with global privacy regulations. The partnership ecosystem includes technology providers and marketing tools but no direct partner domains were identified. Growth indicators include a comprehensive service offering and a professional online presence.

Security posture

SEI's website demonstrates a mature security posture with HTTPS enforced, strong SSL configuration, and multiple security headers implemented. The presence of cookie consent mechanisms and privacy policies indicates compliance with GDPR and related regulations. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of publicly available incident response or vulnerability disclosure policies and lack of direct security contact emails represent areas for improvement. The use of third-party scripts such as Google Tag Manager and Wisepops is standard but requires ongoing monitoring for security risks. Overall, SEI maintains a strong security culture appropriate for a financial services technology provider.

Recommendations

  1. Publish explicit incident response and vulnerability disclosure policies on the website.
  2. Provide direct security contact channels such as security@seic.com or abuse@seic.com.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance transparency by listing the Data Protection Officer contact information.
  5. Maintain accurate and publicly accessible WHOIS registration data to improve trust.

Technical notes

Notes

The website is built on Drupal 10, a modern and secure CMS platform, indicating a commitment to up-to-date technology. Integration with Google Tag Manager and OneTrust reflects advanced analytics and privacy management capabilities. The use of Akamai CDN and Brightcove video player enhances performance and multimedia delivery. The site is well-optimized for mobile devices and accessibility standards. Meta tags and structured data (JSON-LD) are properly implemented for SEO and social sharing. No technical debt or outdated technologies were observed. Performance is fast, and the site architecture supports a positive user experience. Opportunities exist to further modernize security transparency and incident response readiness.
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.
