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

MODX is a well-established technology company specializing in a custom content management system platform that emphasizes speed, security, and creative freedom. With over 20 years of history, MODX positions itself as a flexible and secure alternative to legacy CMS platforms, targeting web developers, digital agencies, and businesses seeking tailored digital experiences. The company offers open source CMS software, managed cloud hosting, selective content staging, and commercial support services. The website reflects a mature digital presence with professional design, clear navigation, and comprehensive content. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript, jQuery, Font Awesome 6, and integrates analytics and error monitoring tools such as Segment and Sentry. The platform is hosted on MODX Cloud, a managed hosting service, and the site demonstrates fast performance, mobile optimization, and good accessibility. SEO practices are evident through proper meta tags and structured content. From a security perspective, the site enforces HTTPS, uses domain status protections, and implements a cookie consent mechanism compliant with GDPR. However, explicit security policies and incident response information are not publicly available, and DNSSEC is not enabled. No vulnerabilities or exposed sensitive data were detected in the content analysis.

Strategic recommendations include enabling DNSSEC, publishing detailed security and incident response policies, and enhancing security headers to further strengthen the security posture.

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

3 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 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. 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

MODX operates in the technology sector as an open source CMS provider with a complementary managed hosting service. Its business model combines free open source software with commercial support and cloud hosting offerings. The company targets developers and agencies needing flexible, secure, and high-performance CMS solutions. MODX has a strong community presence and leverages partnerships through community forums and professional networks. The long domain age and consistent branding reinforce market credibility. Growth indicators include active GitHub commits and a global community. The company maintains a clear focus on security and performance as competitive advantages.

Security posture

MODX demonstrates a mature security posture with HTTPS enforced and domain registration protections in place. The website uses cookie consent with opt-in, indicating privacy awareness. The use of Sentry for error monitoring shows proactive incident detection capabilities. However, the absence of a published security policy, incident response plan, and vulnerability disclosure program limits transparency. DNSSEC is not enabled, which is a recommended enhancement. No security headers were explicitly detected in the HTML content, suggesting room for improvement. Overall, the security posture is good but could benefit from more explicit policies and technical hardening.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a comprehensive security policy and incident response plan accessible on the website.
  3. Implement and document a vulnerability disclosure program including security.txt.
  4. Add and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Enhance transparency by providing direct security contact channels and data retention policies.

Technical notes

Notes

The website is built on a modern technology stack including MODX Revolution CMS, Bootstrap framework, and popular JavaScript libraries like jQuery. It integrates third-party services such as Segment for analytics and Sentry for error tracking. The site is hosted on MODX Cloud, a managed hosting platform, which provides SSL and platform maintenance. Performance is optimized with caching and fast loading assets. The site is mobile responsive and accessible, with good SEO metadata and Open Graph tags. Technical debt appears low, and the infrastructure supports scalability and security. Opportunities exist to improve DNS security and HTTP security headers.
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.
