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

2 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

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

The bank operates in the finance and real estate sectors, targeting a diverse customer base from private individuals to corporate clients and affluent customers. Its business model centers on regional banking services, supported by partnerships with investment and insurance providers such as Deka and VGH. The website's extensive product catalog and service offerings indicate a comprehensive revenue stream from deposits, loans, investments, and insurance products. The presence of career and community engagement sections suggests a strong brand and local market integration. The digital infrastructure supports customer engagement through multiple channels including chat, phone, and online forms, reflecting a customer-centric approach.

Security posture

The website exhibits a solid security foundation with enforced HTTPS, secure login forms, and a cookie consent banner aligned with GDPR requirements. The inclusion of Dynatrace monitoring scripts indicates active performance and security monitoring. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, explicit declarations of security policies, incident response procedures, and vulnerability disclosure programs are absent, representing an area for improvement. The lack of visible security headers such as Content-Security-Policy or X-Frame-Options in the HTML source suggests potential enhancements to mitigate clickjacking and content injection risks. Overall, the security posture is good but could benefit from increased transparency and header hardening.

Recommendations

  1. Publish a dedicated security policy page detailing security frameworks and practices.
  2. Implement and disclose an incident response and vulnerability disclosure process.
  3. Ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are configured and documented.
  4. Provide clear contact information for the Data Protection Officer to enhance GDPR compliance transparency.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on Adobe Experience Manager, a robust enterprise CMS, enabling modular content management and scalability. The use of JavaScript and CSS is optimized with minified client libraries. Performance is moderate with responsive design and accessibility features such as skip navigation links and ARIA roles. SEO is well addressed with meta tags, canonical links, and structured navigation. The site integrates external services for market data, chatbots, and analytics, indicating a mature digital ecosystem. Hosting details are not explicit, but the domain uses multiple name servers under s-fg-net domains, suggesting professional infrastructure management. Opportunities exist to enhance performance by auditing third-party scripts and optimizing image delivery.
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.
