Security score

54/100

Risk levelMedium

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

The website adcdnx.com functions primarily as a traffic tracking and quality assurance platform for advertisers. Its content is minimal, serving mainly as a placeholder with a brief explanation and a contact email for advertisement inquiries. The domain is well-established since 2014 and uses Cloudflare for DNS management, indicating a stable technical infrastructure. However, the website lacks comprehensive content, privacy policies, and security best practices, which limits its professionalism and trustworthiness. Technically, the site uses minimal technologies with a commented-out Google Analytics script and Cloudflare DNS. There is no evidence of CMS or advanced frameworks. The site performance and mobile optimization are basic, and SEO is poor due to lack of metadata and structured data. Security posture is weak with no security headers detected and no DNSSEC enabled, although HTTPS status is unknown from the provided data. From a security perspective, the site does not expose sensitive data or contain vulnerabilities visible from the content. However, the absence of privacy and cookie policies, security headers, and incident response information indicates low maturity in security and compliance. The WHOIS data is transparent and consistent with the business purpose, supporting legitimacy. Overall, the site scores low to moderate in AI scoring due to minimal content, poor design, and weak security and privacy compliance. Strategic improvements in security headers, privacy policies, and richer content would enhance trust and compliance.

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

11 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

Adcdnx.com operates in the advertising technology sector, focusing on traffic tracking and quality assurance for advertisers. The business model revolves around providing advertisers with tools to monitor and ensure the quality of traffic sources. The domain's age and registration details suggest a stable presence since 2014. The target audience includes advertisers and traffic analysts seeking quality assurance. The company appears small with no public information on parent companies or subsidiaries. The lack of detailed business information and trust indicators limits competitive analysis. The partnership with CPX24, indicated by the contact email domain, suggests a relationship with an advertising network. Revenue streams likely derive from advertising traffic services. Growth indicators and strategic partnerships are not evident from the data.

Security posture

The security posture of adcdnx.com is basic and lacks maturity. The absence of DNSSEC and security headers such as Content-Security-Policy and Strict-Transport-Security reduces protection against common web threats. No incident response or vulnerability disclosure information is provided, indicating limited readiness for security incidents. The site does not expose sensitive data or show signs of vulnerabilities, but the lack of privacy and cookie policies raises compliance concerns, especially under GDPR. The WHOIS transparency is a positive factor for trust. Overall, the site would benefit from implementing standard security best practices and compliance documentation to improve its security culture and reduce risk.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies to improve transparency and GDPR compliance.
  4. Activate and properly configure HTTPS with strong SSL/TLS settings.
  5. Add incident response and vulnerability disclosure information to demonstrate security readiness.

Technical notes

Notes

The website uses minimal technical infrastructure, primarily relying on Cloudflare for DNS and hosting services. The presence of a commented-out Google Analytics script suggests intent to track user interactions but currently inactive. No CMS or advanced frameworks are detected, indicating a simple static or lightly scripted site. Performance is likely moderate given minimal content. SEO and accessibility are poor due to lack of metadata, structured data, and accessibility features. The site would benefit from modernization including responsive design, SEO optimization, and enhanced technical security configurations to reduce technical debt and improve 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.
