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

Admixer is a global AdTech company specializing in full-stack programmatic advertising solutions, including Demand Side Platform (DSP), Supply Side Platform (SSP), Data Management Platform (DMP), header bidding, and RTB stack technologies. The company targets publishers, brands, advertising agencies, and ad traders, positioning itself as a key player in the digital advertising ecosystem with over 15 years of industry experience. Admixer maintains a strong market presence with partnerships with major global demand and supply partners and offers a comprehensive suite of products to optimize media buying and monetization. Technically, the website is built on WordPress with modern web technologies such as jQuery, Google reCAPTCHA, and HubSpot analytics. The site demonstrates good SEO practices, mobile optimization, and accessibility at a basic level. The infrastructure supports a moderate performance level with a professional design and clear navigation, enhancing user experience and trust. From a security perspective, the site enforces HTTPS and employs Google reCAPTCHA for form protection. Cookie consent mechanisms are implemented, reflecting GDPR compliance. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not evident, suggesting room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, Admixer presents a credible and professional online presence with strong business credibility and privacy compliance. The absence of direct contact emails or phone numbers suggests a preference for controlled communication via contact forms. Strategic recommendations include enhancing security headers, publishing explicit security policies, and improving accessibility features to further strengthen the security posture 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

4 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

      • 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Admixer operates in the competitive AdTech sector, offering a broad range of programmatic advertising solutions that cater to multiple market segments including advertisers, publishers, and ad traders. Their business model revolves around providing technology platforms that enable efficient media buying, inventory monetization, and data management. The company leverages partnerships with industry leaders such as Google AdExchange and IAB to enhance market reach and credibility. Customer testimonials and partner logos indicate a healthy ecosystem and positive market reception. The company’s focus on transparency, supply chain control, and data-driven optimization positions it well for growth in the evolving digital advertising landscape.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and the use of Google reCAPTCHA to protect forms from automated abuse. Cookie consent and GDPR compliance are actively managed through a dedicated plugin and visible consent banners. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose the site to certain web-based attacks. No direct incident response contacts or security policies are published, which could hinder rapid response to security incidents. Overall, the security measures are adequate but could be enhanced to meet higher standards and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Enhance website accessibility features to comply with WCAG standards and improve user inclusivity.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Consider adding a vulnerability disclosure program and security.txt file to encourage responsible reporting.

Notes

The website is powered by WordPress CMS version 5.8.10, utilizing jQuery 3.6.0 and various plugins including GDPR Cookie Compliance and Contact Form 7 with added password field and conditional fields. The site loads fonts in modern formats (WOFF, WOFF2) and uses asynchronous loading for analytics and ad scripts to optimize performance. HubSpot analytics and Google reCAPTCHA are integrated for tracking and security. The site demonstrates good SEO practices with Yoast SEO plugin metadata and Open Graph tags. Performance is moderate with room for improvement in accessibility and security header implementation. Hosting provider details are not explicitly identified from the HTML content.
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.
