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

GreenPMPs by Sharethrough is a sustainability-focused programmatic advertising platform aiming to reduce the carbon footprint of digital media campaigns. It leverages partnerships with companies like Scope3 to measure and compensate carbon emissions, positioning itself as an innovator in green media solutions. The website targets advertisers, publishers, and agencies seeking sustainable advertising options and provides tools such as Green Icon certification and custom PMPs for campaign activation. Technically, the site is built on Webflow, uses Cloudflare CDN, and integrates multiple third-party analytics and marketing tools, including Google Tag Manager, Hotjar, and LinkedIn Insight Tag. While the site demonstrates good design, mobile optimization, and performance, it lacks explicit privacy and terms of service documentation, which are critical for compliance and trust. Security posture is moderate with valid SSL but missing modern TLS protocols and DNS security features. The cookie consent mechanism is implemented, indicating some privacy awareness. Overall, the platform is well-positioned in the sustainable advertising niche but should enhance compliance and security transparency to strengthen trust and regulatory adherence.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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

GreenPMPs operates as a specialized SSP within the digital advertising ecosystem, focusing on sustainability and carbon emission reduction. Its business model revolves around offering low-carbon media inventory and certification to brands and agencies, leveraging partnerships with carbon accounting firms. The presence of major brand logos and testimonials indicates a growing client base and market acceptance. The platform supports multiple DSPs and provides educational resources, positioning itself as a thought leader in green advertising. The integration of multilingual support via Weglot suggests a global or multi-regional target audience. The company appears to be medium-sized with a focus on innovation and environmental responsibility, which may provide competitive advantages in an increasingly eco-conscious market.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and HSTS enabled. However, the absence of modern TLS protocols (TLS 1.2 or 1.3) is a significant gap that could expose users to weaker encryption standards. The lack of DNSSEC and CAA records further reduces domain security. No explicit security policies, incident response contacts, or vulnerability disclosure mechanisms are present, which limits transparency and readiness for security incidents. The cookie consent mechanism and secure cookie flags indicate some privacy and security awareness. Overall, the security maturity is moderate but requires improvements in encryption standards, policy publication, and incident response preparedness to meet best practices and regulatory expectations.

Recommendations

  1. Enable TLS 1.2 and TLS 1.3 protocols to enhance encryption security.
  2. Implement DNSSEC and CAA DNS records to protect domain integrity and certificate issuance.
  3. Publish comprehensive privacy policy and terms of service pages to improve compliance and user trust.
  4. Create and publish a security.txt file to facilitate vulnerability disclosure and incident reporting.
  5. Conduct an accessibility audit and improve compliance to enhance user inclusivity.
Technical notes

Notes

The website is built on the Webflow CMS platform and hosted via Cloudflare CDN, ensuring fast content delivery and good performance. It uses a modern tech stack including jQuery, Infinite Scroll, Weglot for multilingual support, and integrates multiple analytics and marketing tools such as Google Tag Manager, Hotjar, and LinkedIn Insight Tag. The site is mobile optimized with responsive design and good navigation clarity. However, the SSL configuration lacks support for modern TLS versions, which is a technical debt and security risk. The absence of DNSSEC and CAA records indicates potential domain security weaknesses. The site uses third-party cookie consent management, which is a positive privacy feature. Overall, the technical infrastructure is solid but could benefit from security protocol upgrades and enhanced compliance documentation.
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.
