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

6 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 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

    • 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

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 website serves a large Spanish-speaking audience interested in economic and financial news, targeting professionals, investors, and general readers. Its business model relies on advertising revenue and premium subscriptions, supported by a broad ecosystem of partners and advertising networks. The presence of OJD certification and consistent WHOIS data reinforces its market credibility. The site covers diverse sectors including finance, energy, transportation, real estate, and technology, reflecting a broad editorial scope. Strategic partnerships with data providers and event organizers enhance its content offerings and market reach.

Security posture

The site employs best practices such as HTTPS, CSP with nonces, and comprehensive consent management via Didomi and Utiq, ensuring compliance with GDPR and user privacy. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a public security policy or incident response contact limits transparency in security governance. The extensive use of third-party scripts necessitates ongoing monitoring to mitigate supply chain risks. Overall, the security posture is robust but could benefit from enhanced public security documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact channels such as security@ or abuse@ emails.
  3. Implement and publish a vulnerability disclosure policy (e.g., security.txt) to encourage responsible reporting.
  4. Regularly audit and update third-party scripts to minimize supply chain vulnerabilities.
  5. Enhance transparency by including data retention policies and DPO contact information.

Technical notes

Notes

The website uses a modern technology stack with asynchronous loading of scripts, advanced ad bidding frameworks (Prebid.js), and multiple consent management platforms. It is hosted on a CDN infrastructure associated with Unidad Editorial, ensuring good availability and performance. The site is mobile-optimized with responsive design and accessibility features. SEO is well addressed with proper meta tags, Open Graph data, and structured data. Some performance optimizations could be considered to improve loading times further, but overall the technical implementation is solid and supports a high-quality 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.
