VSE is the largest energy supplier in Slovakia, providing electricity and gas services to households and businesses. Their website offers a range of services including online account management, energy products like photovoltaic systems and air conditioning, and green energy initiatives. The company targets Slovak domestic and business customers with a comprehensive energy supply and related services portfolio. Technically, the website is built on the Liferay CMS platform, uses modern JavaScript modules, and integrates third-party services such as Google Tag Manager and Cookiebot for analytics and consent management. The site is hosted on Microsoft Azure CDN, ensuring reliable performance and availability. Security-wise, the site enforces HTTPS and uses cookie consent mechanisms, but lacks explicit security headers and published incident response contacts, which are areas for improvement.

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

7 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

      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. 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"

    • 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';…

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

VSE holds a strong market position as Slovakia's largest energy supplier, focusing on electricity and gas distribution. Their business model revolves around energy provision combined with value-added services such as online account management and energy-related products. The company leverages partnerships with technology providers for customer engagement tools and consent management. Growth indicators include promotion of green energy and photovoltaic solutions, reflecting alignment with sustainable energy trends. The website's content and structure support a broad customer base including residential and commercial segments. No direct evidence of parent or subsidiary companies was found, suggesting a focused operational scope. The company maintains a professional digital presence with consistent branding and trust signals such as SSL and cookie compliance.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and use of cookie consent management via Cookiebot, indicating GDPR awareness. However, the absence of explicit security headers (e.g., Content Security Policy, HSTS) and lack of published security policies or incident response contacts reduce the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the provided content. The site uses reputable third-party services for analytics and live chat, which should be monitored for security updates. Recommendations include implementing security headers, publishing a security policy, and providing clear incident response contacts to enhance trust and compliance.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Enhance privacy compliance by publishing a detailed privacy policy and terms of service.
  5. Regularly audit third-party scripts and libraries for vulnerabilities and update accordingly.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging modern JavaScript ES modules and third-party integrations such as Google Tag Manager and Microsoft Omnichannel Live Chat. Hosting is provided via Microsoft Azure CDN, supporting scalability and performance. The site is mobile-optimized with responsive design and uses adaptive media for images. SEO is supported by proper meta tags and Open Graph data. Accessibility features are basic but present. Performance is moderate, with potential improvements in loading speed and accessibility compliance. The technical stack is modern but could benefit from enhanced security configurations and privacy documentation.
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.
