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

18 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

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 · found on this site
  • 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

Jyske Bank operates primarily in the banking and finance sector, serving retail and commercial clients. Its business model focuses on providing comprehensive financial products and services through both physical branches and digital platforms. The bank leverages subsidiaries for mortgage lending, investment management, and financial markets, enhancing its service portfolio. The website reflects a mature digital presence with integrated marketing and analytics tools, supporting targeted advertising and user behavior analysis. The bank's transparent cookie policies and contact information indicate a customer-centric approach. Strategic partnerships and multiple related domains suggest a well-established ecosystem supporting its operations.

Security posture

The website exhibits a solid security foundation with HTTPS enabled and session cookies managing user sessions securely. The presence of bot mitigation cookies indicates proactive measures against automated threats. Consent management for cookies aligns with privacy regulations, enhancing user trust. However, the absence of explicit security headers like Content-Security-Policy and lack of a publicly available security policy or incident response contact represent areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could benefit from enhanced transparency and additional technical controls.

Recommendations

  1. Implement and publicly document security headers such as CSP, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Publish a clear security policy and provide dedicated incident response contact channels to improve transparency and readiness.
  3. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.
  4. Enhance user trust by adding a vulnerability disclosure program or security.txt file.
  5. Continue to monitor and optimize website performance and accessibility to maintain high user experience standards.

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.
