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

Magnite is a leading independent sell-side advertising company specializing in helping media owners and advertisers optimize advertising revenue across multiple channels including Connected TV (CTV), streaming, online video, display, and audio. The company positions itself as a global technology platform with advanced brand protection and targeting capabilities, serving top media owners and brands worldwide. The website reflects a mature enterprise with comprehensive content, professional design, and a strong partner ecosystem including subsidiaries like SpringServe and DV+. Technically, the website is built on WordPress with a modern tech stack including Google Tag Manager, Marketo, LinkedIn Insight, Hotjar, and Swiper.js for UI components. The site is well-optimized for SEO, mobile responsive, and fast loading, indicating a high level of digital maturity. Privacy and legal compliance are well addressed with comprehensive privacy and cookie policies, and GDPR compliance indicators. From a security perspective, the site enforces HTTPS and uses secure forms but lacks explicit security headers and published incident response or vulnerability disclosure information. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is not publicly available, likely due to privacy protection, which is common and justified for a company of this size and industry. Overall, Magnite's website demonstrates a strong business credibility, technical sophistication, and good security posture. Recommendations include enhancing security headers, publishing security policies, and adding vulnerability disclosure mechanisms to further strengthen trust and compliance.

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 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"

  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

Magnite operates in the media and advertising technology sector as the largest independent sell-side advertising platform. Its business model focuses on providing technology and services to media owners and advertisers to maximize advertising revenue, especially in the growing streaming and CTV markets. The company leverages global infrastructure and partnerships to deliver comprehensive advertising solutions across formats. The presence of multiple subsidiaries and partner domains indicates a broad ecosystem. The company targets media owners, brands, and advertisers seeking advanced programmatic and brand-safe advertising solutions. Awards and recognitions highlight industry leadership and innovation. The website content and structure support a large enterprise with global reach and advanced capabilities.

Security posture

Magnite's website security posture is good with mandatory HTTPS enforced and secure form implementations. The absence of security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options is a minor gap that could be addressed to improve defense-in-depth. No exposed sensitive information or vulnerable libraries were detected in the HTML content. Privacy policies and cookie consent mechanisms are comprehensive and GDPR compliant, indicating strong data protection practices. However, the lack of publicly available incident response or vulnerability disclosure information reduces transparency. Overall, the security maturity is appropriate for a large enterprise but could be enhanced by publishing explicit security policies and implementing additional HTTP security headers.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance security posture.
  2. Publish a dedicated security policy and incident response plan on the website to improve transparency and trust.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and tracking pixels to ensure no vulnerable or deprecated libraries are used.
  5. Enhance contact information by providing direct security contact emails and phone numbers for incident reporting.

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.
