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

ASN Bank is a Dutch financial institution specializing in sustainable and ethical banking products. The website presents a comprehensive portfolio including payments, savings, investments, mortgages, insurance, loans, pensions, and business banking services. The bank positions itself as a future-oriented and responsible financial partner, targeting environmentally and socially conscious customers. The site is well-branded and consistent with the bank's mission and values. Technically, the website employs modern JavaScript libraries such as jQuery and jQuery UI, integrates Google Tag Manager for analytics and marketing, and uses a CMS platform inferred as FreeStyle. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Performance is moderate with asynchronous script loading and responsive images. From a security perspective, the site enforces HTTPS, includes CSRF protection scripts, and uses form validation. However, explicit security headers are not detected, and there is no public security policy or vulnerability disclosure page. Privacy compliance is good with a clear privacy policy and cookie consent mechanism. Contact information is primarily via web forms and service pages, with no direct emails or phone numbers visible. Overall, ASN Bank's website is professional, trustworthy, and aligned with its sustainable banking brand. Security posture is solid but could be improved with additional headers and transparency on incident response. The site is safe for general audiences with no adult or questionable content.

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

ASN Bank operates in the niche sustainable banking sector within the Netherlands, offering retail and business banking products focused on ethical finance. Its competitive advantage lies in its strong sustainability branding and transparent product offerings. The business model centers on attracting customers who value environmental and social responsibility. The bank maintains an active presence on major social media platforms and provides multiple service channels including physical ASN stores. Growth indicators include product diversification and digital banking services. Partnerships are evident with corporate and recruitment subdomains. The bank's operations reflect a mature, large-sized financial institution with a clear market position.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and client-side protections such as CSRF tokens and form validation. The absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No vulnerability disclosure or security contact information is publicly available, which limits transparency and incident response readiness. Privacy compliance is well addressed with GDPR-aligned policies and cookie consent. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is good but could benefit from enhanced header policies and published security practices.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  2. Create and maintain a publicly accessible security policy and incident response page with contact details for security issues.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency by providing direct contact emails or phone numbers for customer support and security incidents.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern and modular technical stack with jQuery 3.7.1, jQuery UI, and Google Tag Manager for analytics and marketing. The CMS platform appears to be FreeStyle, which supports structured content and responsive design. The site loads asynchronously where possible and uses responsive images for performance optimization. Accessibility features such as skip links and ARIA attributes are present, indicating good compliance. SEO is supported by meta tags, Open Graph, and JSON-LD structured data. Performance is moderate, with room for improvement in script loading and caching strategies. No major technical debt or outdated technologies were detected.
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.
