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

The website doublclick.net presents itself as an informational platform about the DoubleClick digital advertising service, emphasizing its capabilities in targeted advertising, machine learning, and real-time bidding. The site content is professionally presented with a clear focus on marketing professionals and advertisers seeking digital advertising solutions. However, the site lacks critical compliance and security features such as privacy policies, cookie consent mechanisms, and contact information, which limits its credibility and user trust. Technically, the website is a simple static HTML/CSS/JavaScript site without advanced frameworks or CMS detected. It includes external analytics scripts from stats.computer.com but lacks modern security configurations such as DNSSEC and security headers. Mobile optimization and design quality are good, but accessibility and SEO optimizations are basic. From a security perspective, the site does not implement key best practices such as HTTPS enforcement (not verifiable from provided data), security headers, or incident response contact details. The domain is registered with a reputable registrar since 2000, indicating legitimacy, but the absence of DNSSEC and minimal security posture reduce overall trust. No WAF or blocking mechanisms were detected, and the site content is fully accessible. Overall, the site scores moderately on content and technical implementation but poorly on security and privacy compliance. Strategic improvements in security policies, privacy compliance, and contact transparency are recommended to 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

7 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 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

    • 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

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

Doublclick.net positions itself as a digital advertising platform focused on leveraging machine learning and data analytics to optimize ad campaigns and deliver targeted advertising solutions. The business model centers on providing advertisers with tools for personalized ad creation, real-time bidding, and actionable marketing insights. The target market includes marketers and businesses seeking to improve advertising ROI. The domain's age (since 2000) suggests a mature presence, although the website itself appears minimal and possibly a placeholder or informational site rather than a full service portal. No direct business contact or corporate information is provided, limiting visibility into revenue streams or partnerships. The site references DoubleClick, a known advertising brand, but does not clarify ownership or affiliation, which could impact brand trust. The lack of privacy and security policies may hinder compliance with regulations and reduce attractiveness to enterprise clients.

Security posture

The website exhibits a low security maturity level with no visible security headers, no DNSSEC enabled, and no HTTPS verification from the provided data. There is no evidence of privacy or cookie policies, incident response contacts, or vulnerability disclosure mechanisms. The use of external analytics scripts without clear privacy disclosures further reduces compliance posture. The domain registration status flags (clientDeleteProhibited, clientTransferProhibited, clientUpdateProhibited) provide some protection against unauthorized domain changes. Overall, the security posture is weak and exposes the site to potential compliance risks and trust issues. No critical vulnerabilities or malware indicators were detected in the content.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent mechanism to comply with GDPR and other privacy regulations.
  2. Enable DNSSEC and configure essential security headers (CSP, HSTS, X-Frame-Options) to improve domain and site security.
  3. Add clear contact information including security and incident response contacts to enhance transparency and trust.
  4. Ensure HTTPS is properly configured and enforced site-wide to protect user data and improve SEO.
  5. Develop a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.

Technical notes

Notes

The website is built using standard HTML5, CSS3, and JavaScript without any detected CMS or advanced frameworks. It includes external JavaScript analytics from stats.computer.com. The site is mobile responsive with good design quality and user experience but lacks advanced SEO and accessibility features. Hosting provider and SSL configuration details are not available from the provided data. The domain uses generic anydns.com name servers and does not have DNSSEC enabled, which is a missed opportunity for enhanced DNS security. Performance is moderate, with no broken elements detected. The site appears to be a simple informational or placeholder site rather than a fully featured platform.
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.
