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 advertisers seeking to engage technical audiences with authentic and respectful ad campaigns. The website demonstrates a professional and consistent brand presence, leveraging modern web technologies and secure payment processing via Stripe. The platform integrates analytics and interactive ad units to enhance user engagement and campaign effectiveness. Despite the strong business presentation, the absence of WHOIS registration data raises concerns about domain legitimacy, although external partnerships and verifiable services support the company's credibility. Security posture is generally good with HTTPS and secure payment, but could be improved with additional security headers and explicit privacy compliance mechanisms.

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 advertising sector, targeting a niche market of developers and creators. Its competitive advantage lies in its curated publisher network and focus on native advertising that respects user experience. The business model revolves around connecting advertisers with high-quality tech audiences through managed campaigns rather than self-serve options. Revenue streams likely include advertising fees and campaign management services. The company maintains partnerships with BuySellAds for ad buying and selling platforms, enhancing its ecosystem. Growth indicators include long-term operation since 2010 and testimonials from reputable clients. Strategic observations suggest opportunities to enhance transparency and compliance to strengthen trust further.

Security posture

The website enforces HTTPS and uses Stripe for secure payment processing, indicating a solid baseline security posture. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No public security policy or incident response contacts are published, which limits transparency in handling security incidents. The absence of a vulnerability disclosure program or security.txt file further reduces the security maturity level. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could benefit from enhanced security controls and published policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Add a visible cookie consent banner and detailed cookie policy to improve privacy compliance and user trust.
  3. Publish a comprehensive security policy and incident response contact information to enhance transparency and preparedness.
  4. Consider establishing a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  5. Improve accessibility features and mobile optimization to enhance user experience and compliance with standards.

Technical notes

Notes

The website uses modern JavaScript technologies, integrates third-party services such as Stripe for payments, HubSpot for forms, and Fullres for analytics. The presence of structured data (JSON-LD) enhances SEO and rich snippet capabilities. The site is mobile responsive with good design quality and navigation clarity. Performance is moderate, with asynchronous loading of analytics scripts. No CMS or hosting provider is explicitly identified. Technical debt appears low, but opportunities exist to improve accessibility and security headers. Overall, the technical infrastructure supports the business goals effectively with room for incremental improvements.
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.
