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. Established in 2010, it operates a curated network of over 600 tech-focused sites, providing advertisers with targeted access to a valuable audience. The platform emphasizes respectful advertising that integrates seamlessly with publisher content, supported by testimonials from industry professionals. Technically, the website employs modern web standards, HubSpot for form management, and Stripe for secure payment processing, reflecting a mature digital infrastructure. Security posture is strong with HTTPS and secure payment integration, though some security headers and explicit cookie consent mechanisms are absent. The lack of publicly available WHOIS data suggests privacy protection, which is reasonable for this business type but slightly reduces transparency. Overall, Carbon Ads presents a professional, trustworthy, and well-structured platform for developer-focused advertising.

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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

Carbon Ads occupies a niche market segment targeting developers and creators with native advertising solutions. Its competitive advantage lies in its exclusive network of hand-picked tech sites and a respectful advertising approach that resonates with technical audiences. The business model revolves around connecting advertisers with publishers through managed campaigns rather than self-serve options, ensuring quality and performance. Revenue streams likely include advertising fees and campaign management services. The company leverages partnerships with BuySellAds for buying and selling ads, enhancing its ecosystem. Growth indicators include long-term operation since 2010 and multiple case studies demonstrating campaign success. The platform's strategic focus on developer communities and technical authenticity positions it well within the technology advertising sector.

Security posture

The website demonstrates a solid security foundation with HTTPS enforced and secure payment processing via Stripe. No sensitive data is exposed in the HTML content, and the use of structured data enhances trustworthiness. However, the absence of common security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options represents an area for improvement. There is no publicly available security policy or incident response contact information, which could enhance transparency and readiness. The lack of a cookie consent mechanism may pose compliance risks under GDPR. Overall, the security posture is good but could be strengthened by implementing additional headers, publishing security policies, and enhancing privacy compliance measures.

Recommendations

  1. Implement standard security headers including CSP, HSTS, and X-Frame-Options to harden the website against common attacks.
  2. Add a clear cookie consent banner/mechanism to comply with GDPR and other privacy regulations.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external resources.

Notes

The website is built using modern web technologies including HTML5, CSS3, and JavaScript, with HubSpot forms embedded for data collection and Stripe for payment processing. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with asynchronous loading of analytics and ad scripts. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD markup. The use of BuySellAds network scripts indicates integration with a broader advertising ecosystem. Technical debt appears low, but opportunities exist to enhance security headers and privacy compliance. Hosting provider details are not explicitly identified. Overall, the technical infrastructure supports a professional and scalable advertising platform.
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.
