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 technology sectors as an essential entity with an enterprise scale. Its business model focuses on providing sell-side advertising technology platforms that enable media owners to monetize their inventory programmatically while offering advertisers advanced targeting and brand safety features. The company maintains a global presence and partners with key industry players such as Rubicon Project and SpringServe. Revenue streams likely include platform fees, technology services, and data-driven advertising solutions. The website content and external links indicate a strong partnership ecosystem and active engagement with industry trends. Growth indicators include recent awards, press releases, and a comprehensive content strategy targeting buyers and sellers. The company emphasizes innovation, privacy, and transparency as competitive advantages.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, secure form handling, and absence of exposed sensitive data. However, there is no explicit security policy or incident response contact information published, which is a compliance gap. No security.txt or vulnerability disclosure mechanisms are found, limiting external reporting channels. The site uses modern analytics and marketing scripts but does not show signs of vulnerable libraries or outdated technologies. Privacy policies and cookie consent mechanisms are comprehensive, supporting GDPR compliance. Overall, the security posture is strong but could be improved by publishing formal security policies and incident response procedures to enhance transparency and readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance frameworks.
  2. Add incident response contact information or a security@ email address for vulnerability reporting.
  3. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  4. Verify and explicitly implement security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  5. Maintain transparency in domain registration or consider reducing privacy protection to improve trust.

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.
