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

3 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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. 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

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

Illumia operates in the competitive Italian energy market, offering fixed and indexed pricing models for electricity and gas, fiber internet services, and photovoltaic installations. The company leverages partnerships with consumer associations to enhance trust and compliance. Its digital marketing strategy includes active use of Trustpilot for reputation management and Google marketing tools for user acquisition and retargeting. The presence of a blog and press releases indicates ongoing engagement and transparency. The company appears to be large-scale with a broad customer base and a focus on sustainability and innovation.

Security posture

The website enforces HTTPS and employs Google reCAPTCHA to protect forms from abuse. Cookie consent is managed via a robust third-party solution (Iubenda), allowing granular user control. No exposed sensitive data or vulnerable libraries were identified. However, the absence of explicit security headers like Content-Security-Policy and X-Frame-Options is a minor gap. No public security policy or incident response contact is provided, which could be improved to enhance transparency and readiness. Overall, the security posture is good but can be strengthened with additional headers and documented policies.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page including incident response procedures and contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts and plugins to minimize vulnerability exposure.
  4. Enhance monitoring and logging capabilities to detect and respond to security incidents promptly.
  5. Continue to maintain and improve privacy compliance mechanisms in line with evolving regulations.

Technical notes

Notes

The website uses a WordPress CMS with a modern and diverse technology stack including jQuery, Select2, Material Components Web, FlipClock, and multiple third-party integrations for analytics, marketing, and customer support. The site is mobile-optimized with responsive design and good accessibility features. SEO is enhanced via Yoast SEO plugin with proper meta tags and structured data (JSON-LD).

Overall, the technical infrastructure supports a professional and scalable web presence.
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.
