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

2 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.

    • 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. 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 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

Selectra operates in the energy and telecommunications sectors primarily, with extensions into finance, insurance, and home security. Its business model revolves around providing free comparison tools and advisory services to optimize household and business expenses. The company has a strong market presence in Spain and international sister sites in multiple countries, indicating a broad geographic footprint. The platform's revenue likely comes from partnerships and commissions with service providers. The presence of multiple contact points and customer testimonials enhances credibility. The company targets residential consumers and businesses seeking cost savings and service optimization.

Security posture

The website employs HTTPS with a good SSL configuration and includes security headers such as Content-Security-Policy with nonce values. Cookie consent is implemented with category-based user choices, indicating GDPR compliance. No sensitive data leaks or vulnerable libraries were detected in the HTML content. However, the absence of a published security policy, incident response information, or vulnerability disclosure program suggests room for improvement in transparency and preparedness. Overall, the security posture is good but could be enhanced by publishing formal security documentation and incident contacts.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and user data protection.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency by including data retention policies and more detailed privacy compliance information.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve user trust.

Technical notes

Notes

The website is built on Drupal 10 CMS, using modern front-end libraries like Swiper.js for carousels and intl-tel-input for phone input formatting. Google Tag Manager and Google Analytics are used for tracking and marketing analytics. The site is mobile-optimized with responsive design and accessibility considerations. Performance is moderate, with external font loading and multiple CSS files. The site uses a Content-Security-Policy nonce to mitigate script injection risks. No hosting provider information was found in the HTML. The technical stack is modern and well-maintained, supporting a professional user experience.
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.
