Priority findings

2 findings rated critical or high in the checks that completed. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • Email security: did not complete in this scan.
  • Network security: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

MVM Next holds a strong position in the Hungarian energy market with a broad portfolio of services and subsidiaries. Its business model focuses on utility provision combined with digital customer engagement and value-added services such as solar energy and insurance. The company targets both residential and commercial segments, leveraging online portals for service delivery. Partnerships with specialized subsidiaries and related domains enhance its market coverage. The lack of visible contact information on the homepage suggests a focus on digital self-service. The company appears mature and well-integrated in the national energy infrastructure.

Security posture

The website demonstrates a good security baseline with HTTPS and a GDPR-compliant cookie consent mechanism. Use of Google Tag Manager and Hotjar is managed with user consent. However, the absence of key security headers (CSP, HSTS, X-Frame-Options) is a notable gap. No explicit security or incident response policies are published, and no dedicated security contact channels are visible. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is good but could be improved by adding security headers and transparency around incident response.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Add clear contact information including phone numbers and emails on the website to improve customer support and credibility.
  4. Enhance accessibility compliance to ensure better usability for all users.
  5. Improve SEO by adding structured data (JSON-LD) and comprehensive meta tags for better search engine visibility.

Technical notes

Notes

The website is built on a legacy ASP.NET WebForms platform enhanced with modern JavaScript libraries such as jQuery, Flexslider, and Fancybox. Google Tag Manager and Hotjar are used for analytics and user behavior tracking with consent management. The site loads moderately fast but could benefit from performance optimizations. Mobile optimization is good with responsive design elements. The absence of a modern CMS suggests custom development. Technical debt may exist due to legacy framework usage, but the site remains functional and professional. Opportunities exist to modernize the tech stack and improve SEO and accessibility.
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.
