MAVIR Zrt. is the Hungarian Transmission System Operator responsible for managing the national electricity transmission network and market operations. The company operates critical infrastructure, provides system and market operation services, and supports business development and regulatory compliance. The website reflects MAVIR's role as a key national energy entity with a large operational scope and multiple subsidiaries. The site targets energy sector professionals, partners, and the general public interested in electricity transmission and market data. Technically, the website is built on the Liferay CMS platform, utilizing modern web technologies such as jQuery, Bootstrap, and Google Analytics. It demonstrates good mobile optimization, accessibility, and SEO practices, with a moderate performance profile. The site uses HTTPS with strong SSL configuration and implements several security headers, indicating a solid security posture. Security-wise, the site follows best practices including HTTPS enforcement and secure form handling. However, it lacks a visible cookie consent mechanism and dedicated security or incident response policies. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is generally good, with a comprehensive privacy policy and GDPR adherence, though cookie consent could be improved. Overall, MAVIR's website is professional, trustworthy, and well-maintained, reflecting the organization's essential role in Hungary's energy sector. Strategic recommendations include enhancing privacy compliance with cookie consent, publishing security policies, and adding vulnerability disclosure information to further strengthen trust and compliance.

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

9 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

MAVIR holds a critical position as Hungary's electricity transmission system operator, managing infrastructure and market operations. Its business model is that of a regulated entity, likely state-owned or under government oversight. The company maintains a network of subsidiaries supporting various operational and service aspects. Revenue streams likely derive from transmission fees, market operation services, and ancillary services such as relay protection and accredited laboratory testing. The website's content and structure indicate a focus on transparency, regulatory compliance, and stakeholder engagement. Partnerships and subsidiaries are clearly listed, supporting a broad ecosystem. Growth indicators include ongoing projects and market integration initiatives. The company targets energy market participants, regulators, and the public, emphasizing reliability and transparency.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and multiple security headers implemented, including HSTS, X-Frame-Options, and Content-Security-Policy. Forms include validation and secure handling. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a visible cookie consent banner and dedicated security or incident response pages indicates room for improvement in privacy and incident management transparency. The use of Google Analytics and Tag Manager introduces moderate user tracking, which is common but requires clear privacy disclosures. Overall, the site balances security and usability well but should enhance privacy compliance and incident response visibility.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and enhance user privacy transparency.
  2. Publish a dedicated security policy and incident response information page to improve trust and preparedness.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance privacy disclosures regarding data collection, retention, and user rights to strengthen GDPR compliance.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging modern JavaScript libraries such as jQuery and Bootstrap for UI components. Google Analytics and Tag Manager are used for analytics and tracking. The site is responsive and optimized for mobile devices, with accessibility features implemented. Performance is moderate, with combined and minified resources served via combo URLs. The use of SVG polyfills and progressive enhancement techniques indicates attention to cross-browser compatibility. Technical debt appears low, but opportunities exist to improve privacy and security transparency. Hosting details are not explicit but the SSL configuration is strong, indicating professional hosting infrastructure.
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.
