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.

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. 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

onvista bank leverages its parent company Commerzbank AG's reputation to maintain a strong market position in the German online brokerage sector. The business benefits from a broad product offering and integration with partner sites such as onvista.de for financial news and analysis. The website's clear navigation and detailed service descriptions support customer acquisition and retention. The use of Usercentrics for cookie consent and Google Tag Manager for analytics reflects a balanced approach to marketing and privacy compliance. The absence of direct email contacts but presence of phone and contact forms aligns with standard banking communication practices. The partnership ecosystem includes financial media and trading platforms, enhancing service reach.

Security posture

The website demonstrates a good security baseline with HTTPS and cookie consent mechanisms. Security information pages educate users on transaction safety and fraud warnings. However, the lack of explicit security headers (e.g., CSP, HSTS) and absence of a published vulnerability disclosure or security.txt file indicate areas for improvement. No direct incident response contacts or abuse emails were found, which could hinder timely reporting of security issues. The use of third-party scripts like Google Tag Manager and Usercentrics is standard but requires ongoing monitoring for vulnerabilities. Overall, the security posture is adequate for a financial services website but could be enhanced with additional best practices and transparency.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file and provide clear incident response contact information to facilitate vulnerability reporting.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Maintain transparency on data retention policies and update privacy documentation accordingly.

Technical notes

Notes

The website uses TYPO3 CMS, a robust open-source content management system, combined with modern JavaScript libraries including jQuery 3.6.0 and Bootstrap for responsive design. Font Awesome provides iconography. Cookie consent is managed via Usercentrics, indicating compliance with privacy regulations. Google Tag Manager is used for analytics and marketing tags. The site loads asynchronously for performance optimization but could benefit from additional performance tuning. Mobile optimization is good, with responsive navigation and layout. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicitly available from the content. Overall, the technical infrastructure supports a professional and secure online banking experience.
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.
