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

OpenX operates as an established advertising technology company with a domain registered since 1996, indicating a mature presence in the ad tech industry. The provided domain openx.net serves primarily as a redirect or informational placeholder directing users to the main corporate site www.openx.com. The business focuses on programmatic advertising and digital ad monetization services targeting advertisers and publishers. The minimal content on this domain limits direct insight into the full scope of their offerings. Technically, the domain is hosted with Google Cloud DNS and uses multiple Google name servers but lacks DNSSEC, which is a recommended security enhancement. The HTML content is minimal with no metadata, scripts, or tracking technologies detected, indicating a low digital footprint on this domain. The absence of privacy, cookie, or terms of service policies on this domain reduces compliance visibility. No security headers or incident response information is published here. From a security perspective, the domain shows basic protections such as clientTransferProhibited and clientUpdateProhibited status flags in WHOIS, which help prevent unauthorized domain changes. However, the lack of DNSSEC and security policies, as well as no visible HTTPS enforcement details, suggest room for improvement. No vulnerabilities or malicious indicators were detected in the limited content. Overall, the risk associated with this domain is moderate due to minimal content and lack of compliance documentation. Strategic recommendations include enabling DNSSEC, publishing privacy and security policies, and improving technical SEO and content quality to enhance trust and compliance posture.

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

10 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

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 is positioned as a significant player in the advertising technology sector, providing programmatic advertising solutions and digital ad monetization platforms. Their business model revolves around connecting advertisers and publishers through automated ad exchanges. The company targets digital marketers, advertisers, and publishers seeking efficient ad placement and revenue optimization. The domain age and registrar data support a long-standing market presence. However, the analyzed domain openx.net appears secondary to the main corporate domain, with limited direct business content. No partner or subsidiary domains were identified from the provided data. The lack of published certifications or trust badges on this domain suggests that such information may be centralized on the main site.

Security posture

The security posture of openx.net is basic but not robust. The domain benefits from WHOIS status flags that prevent unauthorized transfers and updates, which is a positive control. However, the absence of DNSSEC reduces DNS security. No security headers or HTTPS enforcement details were found in the provided content, limiting protection against common web attacks. No incident response or vulnerability disclosure information is published, which could hinder timely security communications. The lack of privacy and cookie policies also indicates potential compliance gaps with GDPR and other regulations. Overall, the domain shows minimal security maturity and would benefit from enhanced security controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Publish comprehensive privacy and cookie policies to enhance GDPR compliance and user trust.
  3. Implement and enforce HTTPS with proper SSL/TLS configuration and security headers such as Content-Security-Policy and X-Frame-Options.
  4. Provide clear security policies and incident response contact information to improve transparency and readiness.
  5. Enhance website content quality and navigation to improve user experience and SEO performance.

Technical notes

Notes

The domain openx.net is hosted with Google Cloud DNS, utilizing Google name servers, indicating a reliable hosting infrastructure. The HTML content is minimal, lacking metadata, scripts, or analytics tools, which suggests a low technical complexity but also limited user engagement features. No CMS or frameworks were detected. The absence of DNSSEC is a technical shortcoming. Performance is likely moderate given the minimal content, but mobile optimization and accessibility cannot be assessed from the provided data. SEO optimization is poor due to lack of meta tags and structured data. Overall, the technical implementation is basic and could be modernized to support better security, compliance, and user experience.
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.
