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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  3. 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

  • 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

The company operates in the energy sector, focusing on electricity distribution and network services for a defined geographic area. Their business model revolves around supplying electricity, including renewable sources, and managing the local grid infrastructure. The presence of a customer portal indicates digital engagement with clients. The company appears to be a small-sized local utility with no visible parent or subsidiary companies. Their competitive advantage lies in local presence and direct service to the community. The website content and structure support clear communication of services and customer support, with indications of ongoing network management and outage handling. Partnerships or related domains are not explicitly identified.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No explicit incident response or abuse contact information is provided, which could hinder timely handling of security incidents. The site uses standard WordPress and Elementor plugins, which require regular updates to mitigate vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Privacy compliance is partial, with a privacy policy but no cookie consent mechanism. Overall, the security posture is adequate but could be improved with additional controls and transparency.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  2. Publish an incident response or abuse contact page/email to improve security incident handling.
  3. Add a cookie consent banner/mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Regularly audit and update WordPress plugins and themes to reduce vulnerability risks.
  5. Consider appointing and publishing Data Protection Officer contact details to strengthen privacy governance.

Technical notes

Notes

The website is built on WordPress CMS with Elementor page builder, leveraging jQuery and Font Awesome for UI elements. The site uses modern SEO practices including meta tags, Open Graph, and JSON-LD structured data for organization and webpage information. Performance is moderate with some lazy loading and responsive design features. Accessibility is basic but present, with skip links and semantic HTML. No major technical debt or deprecated technologies were detected. Hosting provider details are not explicitly identified. The site uses WP Statistics for analytics, indicating minimal user tracking. Overall, the technical infrastructure supports a stable and user-friendly experience but could benefit from enhanced security configurations and performance optimizations.
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.
