The website serves as an authoritative source of information for financial institutions, government entities, and the public interested in Hungary's financial system. The site demonstrates a professional design with clear navigation and a focus on compliance with privacy regulations, including a comprehensive cookie consent mechanism and privacy policy. Technically, the website employs modern web technologies such as Vue.js and Google Tag Manager, ensuring a responsive and moderately performant user experience.

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, 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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

MNB holds a critical position in Hungary's financial sector as the national central bank. Its business model is governmental, focusing on regulatory and supervisory roles rather than commercial activities. The website targets financial professionals, regulators, and the general public, providing detailed information on monetary policy, financial stability, and supervisory frameworks. The institution benefits from strong brand recognition and trust, supported by consistent branding and authoritative content. While the site integrates analytics and tracking for performance insights, it maintains compliance with GDPR through clear cookie policies. The absence of visible contact emails or phone numbers in the provided content suggests a controlled communication approach, typical for governmental entities. The bank's digital ecosystem appears well-managed, with opportunities to expand transparency and user engagement through enhanced contact and security disclosures.

Security posture

The website exhibits a strong security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive data. The use of modern JavaScript frameworks and analytics is balanced with privacy compliance mechanisms, including a cookie consent banner with a 90-day lifespan. However, the lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates areas for improvement in transparency and readiness. No vulnerabilities or suspicious domains were detected in the analysis. The security score reflects a mature but improvable state, recommending the publication of security policies and dedicated incident response channels to align with best practices and regulatory expectations.

Recommendations

  1. Publish a dedicated security policy and incident response page with clear contact channels.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Enhance accessibility features to meet higher compliance standards.
  4. Provide explicit company contact information including emails and phone numbers for support and security.
  5. Regularly review and audit third-party scripts and analytics tools for security and privacy compliance.

Technical notes

Notes

The website is built using modern web technologies including Vue.js and Google Tag Manager, indicating a contemporary front-end architecture. The HTML and CSS are valid and support responsive design, contributing to good mobile optimization and user experience. Performance is moderate, with potential for improvement through optimization of external scripts and assets. The site lacks a detected CMS, suggesting a custom or proprietary platform. Hosting details are not explicitly available, but the presence of security headers and HTTPS indicates a professionally managed infrastructure. Opportunities exist to improve technical SEO and accessibility compliance further, enhancing overall digital maturity and resilience.
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.
