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

  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

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

Columbus Energy operates in the renewable energy sector with a focus on photovoltaic installations and related energy-saving technologies. Their business model revolves around providing end-to-end services including product supply, installation, subsidy application assistance, and financing solutions. The company targets residential customers, commercial entities, and housing associations, leveraging government subsidy programs to enhance value propositions. Their multilingual web presence and partnerships across Central and Eastern Europe indicate a strategic regional expansion. Trust signals such as certifications, extensive references, and a client section reinforce their market credibility. The company benefits from a strong parent group backing, which supports scalability and operational stability.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of security and privacy plugins (Complianz), and secure data collection forms with anti-CSRF tokens. Tracking and analytics are implemented with user consent mechanisms in place, aligning with GDPR requirements. However, the absence of a dedicated security policy page, incident response contact details, and a security.txt file indicates room for improvement in transparency and readiness. Security headers are minimal, suggesting potential enhancements in HTTP header security. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the site is secure for users but could benefit from enhanced security documentation and headers.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and user data protection.
  2. Add incident response contact information such as security@ or abuse@ email addresses.
  3. Implement a security.txt file to facilitate vulnerability disclosures.
  4. Enhance HTTP security headers including Content-Security-Policy and X-Content-Type-Options.
  5. Regularly review and update third-party scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress CMS using a modern and widely supported technology stack including jQuery and various analytics and marketing tools. Hosting is supported by Cloudflare DNS and nameservers, providing performance and security benefits. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with caching and optimization plugins in use. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD schema. The site uses multiple external resources and scripts, which are common for marketing and analytics but require ongoing security monitoring. Overall, the technical infrastructure is robust and supports the business goals effectively.
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.
