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

  2. Security headers

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

Business profile

ESCO Slovensko operates as a joint venture between ČEZ and SPP, leveraging their regional energy market leadership. Its business model focuses on providing comprehensive energy solutions and services, including financing options and facility management, targeting corporate and public sector clients. The company’s competitive advantage lies in its strong backing by established energy groups and its broad service portfolio. The presence of multiple subsidiaries indicates a diversified operational structure. The website content and linked domains reflect a well-established partnership ecosystem. Growth indicators include active marketing, certifications, and a clear digital strategy. The company positions itself as a key player in energy efficiency and sustainability in Slovakia and Central Europe.

Security posture

The website exhibits a solid security maturity level with HTTPS enforced and partial content security policy implementation. The use of a GDPR-compliant cookie consent mechanism and absence of exposed sensitive information indicate good data protection practices. However, there is no visible vulnerability disclosure policy or security.txt file, and no incident response contacts are published, which are areas for improvement. The site uses modern libraries and scripts with no known vulnerabilities detected in the provided content. Overall, the security posture is good but could be enhanced by formalizing vulnerability disclosure and incident response processes.

Recommendations

  1. Publish a security.txt file to facilitate vulnerability disclosure.
  2. Provide clear incident response contact information on the website.
  3. Enhance Content Security Policy with explicit directives to reduce risk.
  4. Regularly audit and update third-party scripts and plugins to mitigate vulnerabilities.
  5. Consider publicly listing a Data Protection Officer contact to improve GDPR transparency.

Technical notes

Notes

The website is built on WordPress 6.8.2 with a modern tech stack including Bootstrap 5.3.3, Swiper.js, and jQuery 3.7.1. Performance optimizations are implemented via WP Rocket, including lazy loading of images and scripts, and prefetching links. The site is mobile-optimized with responsive design and accessibility considerations. SEO is enhanced with comprehensive metadata and JSON-LD structured data. Hosting provider details are not explicitly detected. The technical infrastructure supports a fast, secure, and user-friendly experience with minimal technical debt visible from the source. Opportunities include further CSP hardening and formal security 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.
