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

OpenX is a leading independent supply-side platform specializing in programmatic advertising, providing a transparent and fair marketplace for publishers and advertisers. The company emphasizes demand addressability, transparency, and sustainability, positioning itself as an innovative player in the open web advertising ecosystem. Their services include omnichannel targeting, premium inventory offerings, and responsible media initiatives. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content tailored to industry stakeholders. Technically, the site is built on WordPress with modern frameworks like Bootstrap and integrates advanced analytics and consent management tools, indicating a high level of digital maturity. Security posture is strong with HTTPS enforcement and cookie consent mechanisms, though explicit security policies and incident response details are not publicly visible. The absence of WHOIS data is a notable anomaly but does not detract significantly from the overall trustworthiness given the professional branding and social proof. Strategic recommendations include publishing detailed security and privacy policies and enhancing transparency around data protection roles.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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 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';…

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

OpenX operates in the technology and media sectors, targeting digital publishers and advertisers globally, primarily from the United States. Their business model revolves around providing a programmatic advertising exchange platform that facilitates efficient ad buying and selling with a focus on transparency and sustainability. The company leverages partnerships and proprietary technologies to maintain a competitive edge. Their market position is strengthened by their independent status and commitment to open web principles. The presence of customer testimonials and social media engagement further supports their credibility. Growth indicators include innovative product launches like OpenXSelect™ and Impact PMPs. The company maintains a large-scale operation with a professional online presence, though some corporate details such as founding year and registrant data are not explicitly disclosed on the site.

Security posture

The website demonstrates a solid security foundation with HTTPS enabled and multiple security headers likely in place. Cookie consent and privacy management are actively implemented, reflecting compliance with GDPR and other privacy regulations. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the HTML content. The integration of third-party analytics and marketing scripts is managed with user consent, mitigating privacy risks. Overall, the security maturity is good but could be enhanced by publishing formal security documentation and contact channels for incident reporting.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the homepage.
  2. Add a dedicated security policy page detailing frameworks and incident response procedures.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Provide contact information for a Data Protection Officer or security team.
  5. Regularly audit third-party scripts and update security headers to maintain best practices.

Technical notes

Notes

The website is built on WordPress CMS with Bootstrap framework, leveraging jQuery and modern JavaScript libraries. It integrates Google Tag Manager, Google Analytics, HubSpot, and LinkedIn Insight for analytics and marketing automation. CookiePro is used for consent management, ensuring compliance with privacy laws. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely influenced by multiple external scripts. SEO is well-implemented with proper meta tags, Open Graph data, and structured JSON-LD schema. Hosting provider details are not explicitly identified. The technical stack is modern and robust, supporting the business needs effectively. Opportunities exist to optimize performance further and enhance security transparency.
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.
