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. 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

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

Adform operates in the technology and media sectors, providing enterprise-level advertising solutions primarily to advertisers and publishers. Their business model revolves around offering a comprehensive media buying platform with advanced identity and data management capabilities. The company emphasizes data ownership and privacy, aligning with GDPR compliance and industry certifications. Their market position is strong, supported by global offices and a wide partner ecosystem. The website content and structure indicate a focus on transparency, client support, and innovation, with strategic investments in AI-driven campaign planning and carbon reduction initiatives. The presence of client testimonials and industry memberships further enhances credibility and market trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and a cookie consent mechanism aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit incident response contacts and vulnerability disclosure policies are not publicly available, representing an area for improvement. The integration of trusted third-party marketing and analytics services is managed with user consent, indicating responsible data handling. Overall, the security practices support business continuity and regulatory compliance, though enhancing transparency around incident response would strengthen the security culture.

Recommendations

  1. Publish clear incident response and abuse contact information on the website.
  2. Implement and publicize a vulnerability disclosure policy or security.txt file.
  3. Enhance transparency by detailing data retention policies and user data handling practices.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Continue investing in privacy compliance and user consent mechanisms to maintain trust.

Overall, the technical infrastructure supports scalability, security, and user engagement effectively.
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.
