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

5 findings rated critical or high. Fix these first.

  1. 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';…

  2. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 Brief operates in the media sector with a focus on environmental and climate topics. Its business model revolves around content creation and dissemination, targeting a niche but globally relevant audience. The organization leverages newsletters and social media channels to engage users and expand reach. While no direct revenue streams or parent company information is publicly available, the site’s consistent branding and comprehensive content suggest a stable medium-sized operation. The absence of explicit contact emails and phone numbers indicates a preference for controlled communication via contact forms. The website’s integration with marketing and analytics platforms supports data-driven audience engagement and growth strategies.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and the use of Google reCAPTCHA to protect forms from automated abuse. No sensitive information is exposed in the HTML content, and third-party scripts are loaded asynchronously to reduce risk. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents an area for improvement. There is no evidence of a published vulnerability disclosure policy or security.txt file, which could enhance transparency and incident response readiness. Overall, the site is secure for its purpose but could benefit from additional hardening measures and formal security communication channels.

Recommendations

  1. Implement explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a security.txt file to provide clear vulnerability disclosure instructions and improve incident response transparency.
  3. Regularly audit and update third-party scripts and plugins to mitigate risks from vulnerable libraries.
  4. Consider adding visible company contact emails or phone numbers to improve trust and facilitate direct communication.
  5. Enhance privacy compliance disclosures by detailing data retention policies and user rights more explicitly.

Technical notes

Notes

The website is built on WordPress CMS using Bootstrap for responsive design and jQuery for client-side scripting. It integrates multiple third-party services including Google Analytics, Google Tag Manager, Hotjar for user behavior analytics, Facebook SDK for social media integration, and MailerLite for email marketing and newsletter management. The site uses modern web standards and is mobile-optimized with good accessibility and SEO practices, including structured data (JSON-LD) for enhanced search engine understanding. Performance is moderate, likely influenced by multiple external scripts and rich media content. There is no explicit hosting provider information available from the HTML content. Overall, the technical infrastructure supports a professional and scalable media platform with opportunities for optimization in security headers and performance tuning.
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.
