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

AdGreen is a sustainability-focused initiative serving the advertising industry by providing tools and training to measure and reduce carbon emissions in advertising production. The organization offers a bespoke carbon calculator, sustainability training, and a variety of resources to support environmentally responsible production practices. Supported by leading advertising organizations and brands, AdGreen holds a strong market position as a trusted resource for sustainable advertising. Technically, the website is built on the Webflow platform, leveraging modern technologies such as Mixpanel for analytics, Google Tag Manager, Zoho PageSense for user experience optimization, and Cloudflare Turnstile for bot protection. The site demonstrates excellent performance, mobile optimization, and accessibility, with comprehensive SEO and metadata implementation. From a security perspective, the site enforces HTTPS, uses CAPTCHA on forms, and avoids exposing sensitive data. However, it lacks explicit security headers and a public incident response or vulnerability disclosure policy. Privacy compliance is strong, with clear privacy and cookie policies and GDPR adherence. Contact is primarily via web forms, with no direct email or phone contacts publicly listed. Overall, the website presents a low-risk profile with a high degree of professionalism and trustworthiness. The absence of WHOIS data is likely due to privacy protection and does not detract from the site's legitimacy. Strategic recommendations include enhancing security headers, publishing incident response information, and adding a vulnerability disclosure policy to further strengthen trust and security posture.

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 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 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

AdGreen operates as an important entity within the media sector, focusing on sustainability in advertising production. Its business model centers on providing free tools and educational resources to reduce environmental impact, positioning itself as a leader in sustainable advertising practices. The organization benefits from partnerships with major industry players, enhancing its credibility and reach. Revenue streams are likely non-commercial or grant-based, given the free access to tools and training. The target customer segment includes advertising agencies, production companies, and brands committed to sustainability. Growth indicators include active content updates, case studies, and annual reports. The partnership ecosystem is robust, involving leading advertising associations and brands, which supports strategic expansion and influence within the industry.

Security posture

The website demonstrates a mature security posture with HTTPS enforcement and anti-bot measures via Cloudflare Turnstile CAPTCHA. The use of modern analytics and tracking tools is balanced with privacy compliance, including GDPR-aligned policies. However, the absence of 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 incident response plan or security contact limits transparency in handling security incidents. Overall, the security maturity is good but could be enhanced by adopting additional best practices and publicly communicating security policies.

Recommendations

  1. Implement and verify security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish an incident response policy and provide a dedicated security contact email to improve transparency and readiness.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Continue to monitor and update privacy and cookie policies to maintain GDPR compliance and user trust.
  5. Enhance contact options by providing verified company emails or phone numbers to improve business credibility and user support.

Opportunities exist to improve security headers and publish additional security documentation to reduce technical risks.
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.
