0–100, higher is better. How it is calculated

Aristegui Noticias is a well-established Mexican independent news media outlet founded in 2011, providing Spanish-language journalism and video content. The website targets Spanish-speaking audiences interested in free and independent news. Technically, the site uses modern web technologies including Next.js, Google Analytics, and multiple advertising and tracking services such as Taboola and Amazon Ads. The site is hosted behind Cloudflare DNS, enhancing security and performance. Security posture is generally good with HTTPS enforced and domain registration protections in place, but lacks DNSSEC and some security headers. Privacy compliance is limited due to absence of a visible privacy policy and terms of service, though a cookie consent mechanism is present. Overall, the site is professional and trustworthy with moderate user tracking and advertising transparency.

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

9 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 Policy found

      GDPR requires clear information about cookie usage

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

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 business operates in the media sector, focusing on independent journalism with a business model primarily based on advertising revenue. The domain age and registration details support a mature and legitimate operation. The site leverages partnerships with major ad networks and tracking platforms to monetize content. The target market is Spanish-speaking news consumers, primarily in Mexico. The company maintains consistent branding and a professional online presence but could improve transparency by publishing privacy and security policies. No suspicious or fraudulent patterns were detected in domain registration or site content.

Security posture

The website enforces HTTPS and uses Cloudflare DNS, which provides a solid security foundation. However, DNSSEC is not enabled, which is a recommended best practice to prevent DNS spoofing. The site lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain web attacks. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. Privacy compliance is partial, with cookie consent but no clear privacy policy. No exposed sensitive data or known vulnerabilities were detected in the provided content. Overall, the security posture is moderate but can be improved with additional controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security.
  2. Publish a comprehensive privacy policy and terms of service to improve legal compliance and user trust.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built using Next.js, a modern React framework, indicating a contemporary and scalable technical infrastructure. It integrates multiple third-party services including Google Analytics, Google Tag Manager, Amazon Ads, Taboola, and Criteo for analytics and monetization. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site is mobile optimized and uses Google Fonts for typography. Performance is moderate, with deferred and async loading of scripts. No CMS was explicitly detected, suggesting a custom or proprietary content management solution. The site could benefit from improved security headers and DNSSEC implementation to reduce technical risks.
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.
