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

Carbon Ads is a specialized advertising platform focused on delivering native advertising solutions to developers and creators through an exclusive network of over 600 hand-picked tech sites. Founded in 2010, the company positions itself as a trusted partner for brands seeking to engage technical audiences with respect and authenticity. Their business model revolves around connecting advertisers with publishers via curated campaigns, leveraging high-impact ad units and a managed service approach rather than self-serve options. The website demonstrates strong branding, professional design, and clear messaging tailored to its niche market. Technically, the website employs modern web technologies including HubSpot for form management, Stripe for secure payment processing, and BuySellAds as an advertising network partner. The site is mobile-optimized, accessible, and includes structured data for SEO enhancement. Analytics are implemented via Fullres, providing moderate user tracking capabilities. However, some security best practices such as explicit security headers and published incident response policies are absent, representing areas for improvement. From a security perspective, the site uses HTTPS and secure payment gateways, with no visible vulnerabilities or exposed sensitive data. The lack of WHOIS domain registration data is a notable concern, potentially indicating privacy protection or domain registration inconsistencies. No direct company contact emails or phone numbers are published, with contact limited to web forms. Privacy compliance is partially addressed with a privacy policy present, but cookie consent mechanisms are missing. Overall, Carbon Ads presents as a credible and professional advertising service with a strong market niche. The primary risks relate to domain registration transparency and privacy compliance enhancements. Strategic recommendations include improving security header implementation, publishing incident response and vulnerability disclosure information, and adding cookie consent to align with GDPR requirements.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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';…

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

Carbon Ads operates in the technology advertising sector, targeting developers and creators with native advertising solutions. Their competitive advantage lies in their curated network of tech sites and a managed service model that emphasizes respect for users and publishers. Revenue streams derive from advertiser campaign fees and publisher earnings. The company leverages partnerships with BuySellAds for ad sales infrastructure and Stripe for payments. Growth indicators include long-term operation since 2010 and testimonials from reputable clients. The partnership ecosystem includes BuySellAds platforms and HubSpot for marketing automation. The company maintains a focused market presence without self-serve options, emphasizing quality and performance over volume.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS and secure payment processing via Stripe. No sensitive data leakage or vulnerable libraries were detected. However, the absence of key security headers such as Content-Security-Policy and Strict-Transport-Security reduces defense-in-depth. No published security policies or incident response contacts limit transparency and readiness perception. Privacy compliance is partial, lacking cookie consent mechanisms. The WHOIS data absence raises questions about domain registration transparency. Overall, the security maturity is adequate for the business type but could be enhanced by adopting additional best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  4. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Consider clarifying domain registration details or using verified WHOIS data to enhance trust and legitimacy.

Technical notes

Notes

The website is built with modern web standards using HTML5, CSS3, and JavaScript. It integrates HubSpot forms for lead capture and Stripe for secure payment processing. The advertising infrastructure is supported by BuySellAds and Carbon Ads' proprietary ad units. The site is mobile responsive and optimized for accessibility and SEO, including structured data in JSON-LD format. Performance is moderate with asynchronous loading of analytics and ad scripts. No CMS other than HubSpot is detected. Hosting provider details are not explicit. The technical implementation supports a professional user experience but could benefit from enhanced security header configurations and performance optimizations.
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.
