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

5 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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 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's business model centers on providing programmatic advertising technology that connects premium publishers with advertisers seeking targeted audience reach. Their competitive advantage lies in their proprietary audience graph technology, partnerships with major DSPs, and exclusive access to curated supply. Revenue streams likely include ad inventory monetization fees and managed services such as the Deals Desk. The company targets digital advertisers and publishers aiming to maximize ad revenue and campaign outcomes. Growth indicators include a broad partner ecosystem spanning DSPs, publishers, and technology providers, as well as industry certifications that enhance credibility. Strategic observations highlight a focus on contextual advertising and data-driven optimization, positioning Media.net as a key player in the ad tech ecosystem.

Security posture

Media.net demonstrates a mature security posture with HTTPS enforced site-wide and integration of consent management tools to comply with privacy regulations. The presence of multiple tracking pixels and ad technologies is managed with user consent mechanisms, reducing privacy risks. However, the site lacks explicit security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. No security.txt or incident response contact information is published, indicating room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the site content. Overall, the security maturity is good but could be enhanced by adopting additional headers and publishing formal security policies.

Recommendations

  1. Implement and enforce Content-Security-Policy and other security headers to strengthen defense against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Enhance WHOIS data availability or transparency to improve domain registration trustworthiness.
  5. Regularly audit third-party scripts and tracking technologies to ensure compliance and minimize privacy risks.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern JavaScript libraries such as GSAP for animations, Choices.js for custom selects, and standard analytics and advertising pixels including Google Analytics, Facebook Pixel, Bing Ads, and Twitter Ads. Hosting is provided by Webflow, ensuring reliable performance and scalability. The site is mobile-optimized with responsive design and accessibility features like focus-visible outlines. SEO is supported by proper meta tags and Open Graph data. Performance is fast with asynchronous loading of scripts and optimized images. Technical risks are minimal, though reliance on multiple third-party scripts requires ongoing monitoring. Opportunities exist to enhance security headers and formalize privacy and security documentation.
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.
