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

5 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. 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 holds a dominant market position in Czech retail and corporate banking, targeting a broad customer base from individuals to businesses. Its business model focuses on diversified financial products and digital banking services, including the George online banking platform. Partnerships with specialized financial service providers enhance its offerings. The website content and navigation are designed to support customer acquisition and retention, reflecting strategic emphasis on customer-centric digital services. Growth indicators include extensive product lines and integration with investment and insurance partners.

Security posture

The website exhibits a solid security foundation with HTTPS and cookie consent compliance. No exposed sensitive data or vulnerable libraries were detected. However, explicit presence of security headers like Content-Security-Policy and X-Frame-Options was not confirmed in the HTML source and should be verified. Incident response and vulnerability disclosure mechanisms are not prominently visible, suggesting room for improvement in transparency and readiness. Overall, the security posture aligns with industry standards for a major financial institution but could benefit from enhanced public security documentation.

Recommendations

  1. Verify and explicitly implement security headers such as CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  3. Enhance visibility of incident response contacts and security policies on the website.
  4. Conduct regular third-party script audits to mitigate supply chain risks.
  5. Maintain ongoing privacy and security audits to ensure compliance with evolving regulations.

Technical notes

Notes

The website is built on a custom CMS framework (GEM) used by Erste Group, utilizing modern JavaScript, CSS, and integration with analytics and marketing platforms like Google Tag Manager and Evergage. The site is optimized for both desktop and mobile with responsive design and accessibility features. Performance is moderate, with potential improvements in loading speed and resource optimization. The technical stack is robust and suitable for a large enterprise banking website, though monitoring for third-party script vulnerabilities is advised.
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.
