Risk levelMedium

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

The website ad-delivery.net appears to be a minimal technical resource primarily hosting ad delivery related JavaScript files and tracking pixels. It lacks any user-facing content, business descriptions, or contact information, indicating it is not designed as a commercial or customer-facing website. The domain is registered with Cloudflare and has been active since 2017, suggesting some stability but limited public business presence. Technically, the site uses basic JavaScript files and is hosted on Cloudflare infrastructure, but lacks modern SEO, accessibility, and security best practices such as security headers and DNSSEC. The security posture is basic with no evident vulnerabilities but also no advanced protections. Privacy compliance is poor due to absence of privacy or cookie policies. Overall, the site serves a narrow technical function with low business credibility and minimal content quality.

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

9 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

The domain does not present any identifiable business entity or commercial services. It appears to be a backend or support domain for ad delivery scripts, possibly used by other websites or ad networks. There is no evidence of revenue streams, customer engagement, or partnerships. The lack of contact information and policies suggests it is not intended for direct consumer interaction. The business model likely revolves around providing ad delivery infrastructure or tracking services. Market positioning and competitive advantages cannot be assessed due to lack of information.

Security posture

The security posture is minimal but not negligent. The domain uses HTTPS and is hosted on Cloudflare, which provides baseline protections. However, no security headers such as Content-Security-Policy or Strict-Transport-Security are detected, and DNSSEC is not enabled, which could improve domain security. There are no visible vulnerabilities or exposed sensitive data. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other regulations. Incident response and security contact information are not provided, limiting readiness for security events.

Recommendations

  1. Enable DNSSEC to enhance domain name system security and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security to harden the website against common attacks.
  3. Publish clear privacy and cookie policies to comply with GDPR and improve user trust.
  4. Add contact information and incident response channels to facilitate communication and security reporting.
  5. Improve website content quality and structure to enhance credibility and SEO performance.

Key observations

  1. Website content is minimal and appears to be an S3 bucket listing of ad delivery related scripts and tracking pixels.
  2. No user-facing content, policies, or contact information found.
  3. No forms or interactive elements detected.
  4. No metadata such as Open Graph or JSON-LD structured data present.
  5. No external links or social media links found in the content.
  6. Website appears to serve as a technical resource for ad delivery scripts rather than a business-facing site.
  7. No security headers detected; DNSSEC not enabled.
  8. Domain registered with Cloudflare, which provides hosting and DNS services.
  9. No evidence of malicious or adult content.
Technical notes

Notes

The website hosts a small set of JavaScript files related to ad delivery and tracking, served from an S3 bucket with Cloudflare DNS and hosting. The technical stack is minimal, with no detected CMS or frameworks. Performance is likely moderate given the small file sizes and CDN usage. However, the site lacks meta tags, structured data, and accessibility features. There is no evidence of modern frontend frameworks or analytics services. The technical debt appears low but modernization opportunities exist to improve SEO, accessibility, and security configurations.
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.
