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

Business profile

Sparkasse Lüneburg operates as a medium-sized regional bank focused on serving the Lüneburg area in Germany. Its business model revolves around traditional banking services supplemented by digital offerings such as online banking and mobile apps. The bank targets private individuals, young customers, and corporate clients, providing tailored financial products including accounts, loans, investments, and insurance. The presence of certifications like 'Charta der Vielfalt' and 'TOTAL E-QUALITY' highlights its commitment to diversity and corporate responsibility. The bank leverages partnerships with Deka Investments and other Sparkassen group entities to offer a wide product portfolio. The website's comprehensive content and multiple contact channels indicate a customer-centric approach and a well-established market presence.

Security posture

The website demonstrates a solid security posture with enforced HTTPS, secure login forms, and a cookie consent mechanism aligned with GDPR requirements. No signs of exposed sensitive information or vulnerable libraries were detected in the HTML content. The site uses tracking pixels and analytics responsibly with user consent. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not explicitly identified in the provided data, representing an opportunity for enhancement. The absence of a published security policy or incident response contact limits transparency in vulnerability management. Overall, the security maturity is good but could be improved by formalizing security disclosures and enhancing HTTP header configurations.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and provide dedicated contact channels for incident response and vulnerability disclosure to improve transparency and trust.
  3. Conduct regular security audits and update third-party libraries to avoid vulnerabilities.
  4. Enhance user privacy by detailing data retention policies and cookie usage in an easily accessible manner.
  5. Maintain and promote certifications and trust indicators to reinforce market position and customer confidence.

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.
