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

6 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

      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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

NBG operates primarily in the banking sector, offering a wide range of retail, business, corporate, and investment banking services. Its business model focuses on comprehensive financial solutions, including digital banking platforms, loans, insurance products, and investment services. The bank targets both individual customers and corporate clients, emphasizing digital adoption and customer support. The presence of subsidiaries like Εθνική Ασφαλιστική and Εθνική Factors indicates a diversified financial services portfolio. The website's content and structure demonstrate a mature digital strategy with strong brand consistency and trust signals such as official social media channels and regulatory compliance links.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, presence of key security headers (CSP, HSTS, X-Frame-Options), and no visible exposure of sensitive data. Forms include validation and secure data collection practices. No critical vulnerabilities or malware indicators were detected. However, the site lacks explicit public security policies or incident response information, which could be improved to enhance transparency and readiness. Overall, the security measures align with industry best practices for a financial institution of this scale.

Recommendations

  1. Publish a dedicated security policy and vulnerability disclosure program to enhance transparency.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance data retention policy disclosures to comply fully with privacy regulations.
  5. Continue investing in user education and trust-building measures to maintain high credibility.

Technical notes

Notes

The website is built using Angular framework (version 10), leveraging modern JavaScript libraries such as Swiper.js for UI components and Select2 for enhanced select elements. It integrates Google Tag Manager and Google Analytics for tracking and marketing purposes. The CMS used is Sitecore, a robust enterprise-level platform. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with potential for optimization in image loading and script management. The technical infrastructure supports a secure and scalable banking website, though continuous modernization and performance tuning are recommended.
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.
