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 maintains a strong market position as a major internet brand with diversified services in technology and media sectors. Its business model leverages advertising revenue supported by extensive user data collection and analytics. The consent page reflects a sophisticated partnership ecosystem, including 237 partners under the IAB Transparency & Consent Framework, ensuring compliance with GDPR and other privacy regulations. The target audience is broad, encompassing Finnish-speaking internet users, with content tailored for regional compliance. Yahoo's subsidiaries and partner sites enhance its content offerings and market reach. The company exhibits consistent branding and trust signals, reinforcing its credibility in a competitive digital landscape.

Security posture

The website shows a solid security posture with mandatory HTTPS and CSRF token usage in forms, reducing risks of interception and cross-site request forgery. However, explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options are not evident in the provided data, representing an area for improvement. No vulnerabilities or exposed sensitive data were detected in the content. The security score is good, reflecting adherence to best practices for a public-facing consent management page. Incident response and security policy details are not present on this page, which is typical for such a service page but could be enhanced for transparency.

Recommendations

  1. Implement and enforce security headers like CSP, HSTS, and X-Frame-Options to strengthen defense-in-depth.
  2. Enhance accessibility features to improve compliance with WCAG standards and user inclusivity.
  3. Provide explicit security policy and incident response contact information to improve transparency and trust.
  4. Regularly audit third-party scripts and analytics tools to ensure no vulnerable or deprecated libraries are used.
  5. Maintain clear and accessible privacy and cookie policy links with easy user controls for consent management.

Technical notes

Notes

The website uses a modern front-end stack with well-structured HTML, CSS, and JavaScript. It leverages Yahoo's proprietary Rapid analytics framework for user tracking and performance monitoring. The page is mobile optimized with responsive design elements and viewport settings. Performance appears moderate with external CSS and JS loaded from Yahoo's CDN domains. No CMS or hosting provider details are explicitly detected, but the infrastructure is likely managed by Yahoo's enterprise hosting solutions. The site could benefit from enhanced SEO meta tags and improved accessibility markup. Overall, the technical implementation supports a professional and compliant 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.
