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

Media.net is a leading sell-side platform (SSP) specializing in programmatic advertising technology that helps brands and publishers optimize their digital advertising outcomes across multiple screens. The company offers a unique audience graph that integrates SearchSignals with first and third-party data, partnerships with industry-leading verification and measurement providers, and innovative ad formats tailored for the open web. Their platform targets both advertisers and publishers, providing premium curated inventory and monetization solutions. The website reflects a mature, professional digital presence with strong branding and comprehensive content that clearly communicates their value proposition and services. Technically, the website is built on modern web technologies including Webflow CMS, GSAP for animations, and integrates multiple marketing and analytics tools such as Google Tag Manager, Google Analytics, Facebook Pixel, Bing Ads, and Twitter tracking. The site is well-optimized for performance, mobile responsiveness, accessibility, and SEO. Consent management and privacy compliance mechanisms are implemented, indicating a commitment to GDPR and related regulations. From a security perspective, the site enforces HTTPS with strong SSL configuration and includes multiple security headers. No obvious vulnerabilities or exposed sensitive data were detected in the HTML content. However, explicit security policies, incident response information, and vulnerability disclosure mechanisms are not publicly available, which could be improved to enhance trust and transparency. Overall, Media.net presents a trustworthy and professional online presence consistent with a large technology company in the digital advertising sector. The lack of public WHOIS data is likely due to privacy protection, which is common and justified for companies in this industry. Strategic recommendations include publishing detailed security policies, providing direct security contact channels, and maintaining regular audits of third-party scripts to mitigate potential risks.

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. 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

  2. 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

Media.net occupies a strong market position as a sell-side platform in the programmatic advertising ecosystem, serving both publishers and advertisers. Their competitive advantage lies in their proprietary audience graph technology and exclusive partnerships with major DSPs and publishers. The business model focuses on monetizing premium inventory and delivering performance-driven advertising solutions. Revenue streams likely include commissions on ad spend and technology licensing. The target customer segments are digital advertisers seeking premium inventory and publishers looking for high-yield monetization. The company demonstrates growth through strategic partnerships and industry certifications, reinforcing its credibility and market reach. The partnership ecosystem includes well-known DSPs like Criteo, The Trade Desk, and Google Display & Video 360, as well as publisher partners such as Time, New York Post, and WebMD. These relationships indicate a robust operational network and a focus on quality inventory and data-driven advertising.

Security posture

Media.net exhibits a mature security posture with HTTPS enforced site-wide, strong SSL configuration, and multiple security headers that protect against common web vulnerabilities. The presence of a consent management platform aligns with privacy regulations such as GDPR and CCPA. No exposed sensitive information or vulnerable libraries were detected in the site content. However, the absence of publicly available security policies, incident response procedures, and vulnerability disclosure programs suggests areas for improvement in transparency and readiness. The lack of direct security contact information may hinder rapid incident reporting and response. Overall, the security maturity is good but could be enhanced by formalizing and publishing security governance documents and providing clear communication channels for security issues.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and publicize an incident response plan with clear contact channels (e.g., security@media.net).
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency by providing data retention policies and detailed privacy compliance documentation.

Notes

The website leverages a modern technology stack including Webflow CMS for content management, GSAP for advanced animations, and Choices.js for enhanced UI components. It integrates multiple analytics and marketing tools such as Google Tag Manager, Google Analytics, Facebook Pixel, Bing Ads, and Twitter tracking, indicating a sophisticated digital marketing infrastructure.

Opportunities exist to further modernize by adopting security best practices and enhancing transparency around data protection.
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.
