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

1 finding rated critical or high. Fix these first.

  1. 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

GLS Bank operates in the finance sector with a niche in sustainable and ethical banking. Its competitive advantage lies in its long history, social-ecological focus, and recognized market leadership. The business model revolves around offering banking, investment, and financing products that align with sustainability goals. The target customers include individuals, businesses, and non-profits interested in ethical finance. The bank maintains partnerships for online banking and investment platforms, supporting a broad ecosystem. Growth indicators include recent awards and active content marketing. The company emphasizes transparency and accessibility, reinforcing its brand trust.

Security posture

The website employs HTTPS and uses cookie consent management, indicating basic compliance with privacy regulations. However, no explicit privacy policy or terms of service were found in the provided content, which is a compliance gap. Security headers are not detected, and no incident response or vulnerability disclosure information is published, which limits transparency and readiness perception. No vulnerabilities or exposed sensitive data were found in the HTML content. The security score is moderate, with recommendations to improve header implementation and publish security policies. Overall, the security culture appears cautious but could be enhanced with more visible documentation.

Recommendations

  1. Publish a comprehensive privacy policy page clearly linked from the homepage.
  2. Implement and configure security headers such as Content-Security-Policy and X-Frame-Options.
  3. Provide explicit terms of service and security policy documentation.
  4. Establish and publicize an incident response contact or security@ email address.
  5. Regularly audit and update third-party scripts and tracking mechanisms to ensure privacy compliance.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and extensible content management system. It uses modern HTML5, CSS, and JavaScript with structured data (JSON-LD) for SEO. The site includes accessibility tools like the Eye-Able toolbar, enhancing usability for diverse users. Performance appears moderate, with multiple CSS files and scripts deferred or async loaded. External domains are limited to trusted partners and tracking services. There is no indication of outdated or vulnerable libraries in the provided content. Hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and accessible user experience with room for security enhancements.
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.
