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

Carbon Ads is a specialized advertising platform focused on delivering native and targeted advertising solutions to developers and creators. Established since 2010, it operates an exclusive network of over 600 hand-picked tech sites, positioning itself as a trusted partner for brands seeking to engage technical audiences. The website demonstrates strong branding consistency, professional design, and clear messaging tailored to its niche market. Technically, the site employs modern JavaScript, integrates with Stripe for secure payments, and uses HubSpot forms for lead capture, reflecting a mature digital infrastructure. Security posture is solid with HTTPS enforced and secure payment processing, though the absence of explicit security headers and vulnerability disclosure mechanisms suggests room for improvement. Privacy compliance is partially addressed with a privacy policy and cookie policy present, but lacks a consent mechanism. Overall, the site is trustworthy and professional, though the lack of WHOIS data and direct contact details slightly reduce transparency.

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 operates in the technology sector as an essential business entity providing advertising services tailored to developers and creators. Its business model revolves around native advertising campaigns, leveraging a curated network of tech-focused publishers. The company benefits from partnerships with BuySellAds for ad sales and publisher management. Revenue streams likely include CPC advertising and campaign management fees. The target customer segment includes technology companies and brands seeking to reach developer audiences. The presence of testimonials from reputable clients and use of secure payment processors indicate a well-established market presence. Growth indicators include a long operational history and a sizable network. Strategic observations highlight the company's focus on quality over quantity in publisher selection and a consultative approach to campaign management.

Security posture

The website exhibits a good security maturity level with HTTPS enabled and secure payment processing via Stripe. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of common security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. There is no publicly available incident response or vulnerability disclosure information, which could hinder rapid response to security issues. Privacy compliance is partially met with privacy and cookie policies, but lacks explicit consent mechanisms. The security culture appears professional but could benefit from enhanced transparency and formalized security policies.

Recommendations

  1. Implement and verify security headers including CSP, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  2. Publish a security.txt file and establish clear vulnerability disclosure and incident response procedures to improve transparency and trust.
  3. Enhance privacy compliance by deploying a cookie consent mechanism aligned with GDPR requirements.
  4. Provide direct company contact emails and phone numbers for improved communication and trustworthiness.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with integrations to third-party services such as Stripe for payments and HubSpot for form management. The ad delivery is powered by BuySellAds and Carbon Ads proprietary scripts. Performance is moderate with some heavy image assets but overall good mobile optimization and accessibility features. The site lacks a detected CMS, suggesting a custom or static site architecture. Hosting provider details are not evident from the content. SEO is well addressed with proper meta tags, Open Graph data, and structured JSON-LD including organization, website, webpage, FAQ, and review schemas. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
