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

Adform is a leading advertising technology company providing a powerful and safe media buying platform known as Adform FLOW. With over 20 years of innovation and Big 5 validation, Adform serves global clients including advertisers and publishers, enabling them to manage omnichannel advertising campaigns with precision and control. The platform emphasizes data ownership, identity solutions, and omnichannel activation, positioning itself as a trusted partner in the adtech ecosystem. Technically, the website leverages modern web technologies including React, Typekit fonts, and integrates advanced consent management via OneTrust CookiePro. It employs multiple tracking and marketing tools such as Facebook Pixel, LinkedIn Insight Tag, Salesloft, and Piwik Pro analytics, all managed with user consent mechanisms. The site is well-optimized for mobile and accessibility, with a professional design and clear navigation. From a security perspective, the site enforces HTTPS and uses cookie consent banners to comply with privacy regulations. However, explicit security headers are not evident, and no security.txt or incident response contacts are published, which could be improved. The WHOIS data for the subdomain is unavailable, which is typical and not a concern given the strong brand presence and consistent content. Overall, Adform's website demonstrates a mature digital presence with strong business credibility, good privacy compliance, and a solid security posture. Strategic improvements in security header implementation and incident response transparency would further enhance trust and resilience.

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

      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

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, focusing on B2B SaaS solutions for digital advertising. Its market positioning as a powerful and safe media buying platform is supported by a comprehensive suite of services including demand-side platforms, ad servers, data management, and identity solutions. The company targets advertisers and publishers globally, leveraging a network of offices and a partner ecosystem. The business model centers on providing integrated adtech solutions that enable clients to optimize media investments and maintain data control. Growth indicators include continuous innovation, Big 5 validation, and a strong emphasis on privacy and sustainability (carbon reduction). The website content and partner logos reflect a well-established brand with a professional and consistent market presence.

Security posture

The website exhibits a good security maturity level with enforced HTTPS and robust cookie consent management aligned with GDPR requirements. The use of reputable third-party scripts and tracking pixels is managed with user consent, reducing privacy risks. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of a published security.txt file and incident response contact information limits transparency and readiness for vulnerability reporting. Overall, the security posture is solid but could benefit from enhanced header policies and clearer incident response mechanisms.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure guidelines and contact information.
  3. Add explicit incident response contact channels such as security@ or abuse@ email addresses on the website.
  4. Regularly audit third-party scripts and tracking pixels to ensure compliance with privacy policies and minimize tracking risks.
  5. Enhance transparency by providing detailed data retention policies and user rights information in the privacy center.

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.
