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

Union Investment is a well-established financial services company specializing in investment funds, savings plans, and retirement provisions primarily for private customers in Germany. The company has a strong market position supported by over 65 years of experience and recognized industry awards such as the Capital Fondskompass 5 Sterne rating. The website reflects a professional and comprehensive digital presence with rich content, clear navigation, and multiple contact channels including phone, email, chat, and contact forms. Technically, the site uses modern web technologies including web components and a proprietary CMS, hosted and DNS-managed via Cloudflare. However, a critical security issue is the absence of a valid SSL certificate, which severely impacts the security posture and user trust. Privacy compliance is strong with clear privacy and cookie policies and consent management implemented. Overall, the site is professional and trustworthy but requires urgent security improvements to ensure safe user interactions.

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

4 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

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

Union Investment operates in the finance sector, focusing on asset management and investment funds. Its business model revolves around providing investment products and advisory services through a network of cooperative partner banks. The company targets private investors in Germany, offering tailored solutions for savings, retirement, and wealth structuring. The website indicates a mature digital ecosystem with integrations for fund search, calculators, and newsletters, supporting customer engagement and retention. Partnerships with institutional and real estate sectors are evident through related domains. The company maintains a strong brand presence and trust signals, positioning itself as a leading player in the German investment market.

Security posture

The website's security maturity is moderate to low due to the lack of a valid SSL certificate and absence of security headers. While DNS and SPF/DMARC configurations are properly set, the missing HTTPS encryption exposes users to potential risks such as data interception. No incident response or vulnerability disclosure policies are publicly found, indicating potential gaps in security governance. Privacy policies and consent mechanisms are well implemented, reflecting compliance with GDPR. The site uses third-party tracking and marketing tools, which are consent-managed. Overall, the security posture requires immediate remediation of SSL issues and enhancement of HTTP security headers to protect user data and maintain trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable HSTS with includeSubDomains and preload to enforce secure connections.
  4. Publish a vulnerability disclosure policy and security.txt file to improve transparency and incident response.
  5. Conduct regular security audits and update third-party scripts to mitigate vulnerabilities.
Technical notes

Notes

The website employs a modern technical stack with web components built using Stencil.js and a proprietary CMS. It leverages Cloudflare for DNS and likely CDN services, enhancing availability and performance. The site integrates multiple external services including Usercentrics for consent management, Algolia for search, and Mapp Intelligence for analytics. Despite rich content and advanced UI components, the site suffers from slow load times and a large number of resources, impacting performance. Mobile optimization and accessibility are well addressed. The absence of a valid SSL certificate is a critical technical risk. Overall, the infrastructure is robust but requires security and performance optimizations.
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.
