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

Yahoo Inc is a well-established global media and technology company with a strong presence in advertising and digital media solutions. The website presents a professional and comprehensive overview of its services, including Yahoo Ads, DSP, Search, and various media brands such as AOL and Engadget. The company targets advertisers, partners, and general internet users, leveraging its 30+ years of market presence. Technically, the website is built on modern technologies including Webflow CMS, Google Tag Manager, and Hotjar for analytics, hosted via Amazon CloudFront, ensuring fast performance and excellent mobile optimization. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and incident response information are lacking. Privacy compliance is strong with clear policies and GDPR adherence. However, the absence of WHOIS registration data for the domain www.yahooinc.com raises concerns about domain legitimacy despite the professional content and branding. Overall, the site scores well on content quality and technical implementation but is penalized for domain registration inconsistencies.

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

4 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 Policy found

      GDPR requires clear information about cookie usage

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

    • 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 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

  • Network security: did not complete in this scan.
  • 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 Inc operates in the technology and media sectors, providing advertising and data-driven marketing solutions globally. Its business model focuses on connecting advertisers with audiences through omnichannel platforms and leveraging first-party data. The company maintains a strong partnership ecosystem with major media and technology brands, enhancing its market position. Revenue streams likely include advertising sales, DSP services, and search monetization. The website reflects a mature digital presence with comprehensive content, press releases, and career opportunities, indicating ongoing growth and investment in brand and technology. The inclusion of subsidiaries like AOL and Engadget suggests a diversified media portfolio. Strategic observations highlight the importance of maintaining domain legitimacy and enhancing security transparency to support business credibility.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enabled and cookie consent implemented via OneTrust. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security robustness. No direct incident response or vulnerability disclosure information is provided, which could impact readiness for security events. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of WHOIS data for the domain is a significant concern, potentially indicating domain registration issues or privacy protection that is not justified for a public corporate site. Overall, the security maturity is good but could be improved by publishing security policies, adding security headers, and establishing clear incident response contacts.

Recommendations

  1. Implement and publish explicit security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a security policy and incident response information on the website to improve transparency and readiness.
  3. Establish a vulnerability disclosure program and provide a security contact email to encourage responsible reporting.
  4. Clarify domain registration status and ensure WHOIS data is accurate and publicly available to improve trust and legitimacy.
  5. Enhance data protection transparency by providing data retention policies and Data Protection Officer contact information.

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries such as jQuery 3.5.1, and integrates analytics and marketing tools including Google Tag Manager and Hotjar. Hosting is via Amazon CloudFront CDN, contributing to fast load times and global availability. The site is mobile-optimized with responsive design and accessibility features such as focus outlines and skip links. SEO is supported by proper meta tags, Open Graph, and JSON-LD structured data describing the organization and social profiles. No technical debt or deprecated technologies were detected. Opportunities exist to improve security headers and to publish more comprehensive security and privacy documentation to align with best practices.
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.
