Yahoo operates as a major global internet brand providing a wide range of digital services including web portals, search, and advertising. This consent page is part of their GDPR compliance efforts, offering users control over privacy and cookie settings. The website content is professional, well-structured, and localized in Finnish, indicating a mature digital presence. Technically, the site uses modern web standards with HTTPS and includes security measures such as CSRF tokens in forms. However, some security headers are missing which could be improved. Privacy policies and cookie consent mechanisms are comprehensive and clearly linked, reflecting good compliance with GDPR requirements. Overall, the site demonstrates a strong security posture with no visible vulnerabilities or blocking mechanisms, supporting trustworthiness and user confidence.

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 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 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

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

Yahoo is positioned as a leading technology and media company with a broad portfolio of subsidiaries including AOL and Engadget. Their business model centers on advertising and content delivery to a global audience. The consent page reflects their commitment to regulatory compliance and user privacy, essential for maintaining market position in the EU. The company targets general internet users and leverages extensive data collection for analytics and advertising purposes. The presence of multiple partner and subsidiary domains indicates a complex ecosystem supporting their services. Yahoo's enterprise scale and brand recognition provide competitive advantages in the digital media space.

Security posture

The website employs HTTPS with strong SSL configuration and includes CSRF protection in forms, indicating a solid baseline security posture. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options suggests room for enhancement. No exposed sensitive data or vulnerable libraries were detected. The site lacks explicit incident response contacts or security policy disclosures on this page, which could be improved for transparency. Overall, the security posture is good but could benefit from additional hardening and clearer communication of security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy and X-Frame-Options to mitigate common web attacks.
  2. Publish explicit security policy and incident response contact information to enhance transparency and user trust.
  3. Enhance accessibility features to improve compliance and user experience for all users.
  4. Regularly audit third-party scripts and tracking pixels to ensure no vulnerabilities or privacy issues arise.
  5. Maintain up-to-date privacy and cookie policies with clear user controls and easy access.

Technical notes

Notes

The site uses standard web technologies including HTML5, CSS, and JavaScript with external resources hosted on Yahoo's CDN domains. The presence of CSRF tokens in forms indicates attention to secure data handling. The page is mobile optimized and uses responsive design principles. Performance is moderate with room for optimization. No CMS or specific frameworks were detected from the source. Hosting details are not explicit but likely managed by Yahoo's infrastructure. SEO and accessibility are basic but functional. Overall, the technical implementation supports a stable and secure user experience with opportunities for modernization and enhancement.
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.
