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

DNN Software is a technology company specializing in ASP.NET-based content management systems, offering a comprehensive platform that integrates content management, customer relations, marketing, and social engagement. The company positions itself as a leader in the .NET CMS ecosystem with a large community and a broad partner network. Their product suite includes Evoq Content and Evoq Engage, targeting businesses and developers seeking scalable and extensible CMS solutions. The website reflects a mature digital presence with professional design, clear navigation, and extensive resources for customers and partners. Technically, the site leverages a modern tech stack including ASP.NET, jQuery, Google Analytics, Marketo, and Google Tag Manager, ensuring robust marketing and analytics capabilities. The platform is mobile-optimized and SEO-friendly, though accessibility features are basic. Performance is moderate, with room for optimization. Security practices include HTTPS enforcement and cookie consent mechanisms, but lack explicit security headers and published security policies. The security posture is solid but could be enhanced by publishing incident response details and vulnerability disclosure policies. No critical vulnerabilities or exposed sensitive data were detected. Privacy compliance is good, with a comprehensive privacy policy and cookie consent banner, indicating GDPR awareness. Business credibility is supported by clear company information, testimonials, and a consistent brand presence. Overall, the website is professional, trustworthy, and well-structured, though the absence of WHOIS data for the domain introduces some uncertainty about domain registration legitimacy. Strategic recommendations include improving security header implementation, publishing security policies, and clarifying domain registration details to enhance trust.

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

4 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. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

DNN Software operates in the technology sector, focusing on content management systems built on the Microsoft .NET framework. Their business model combines software product sales, professional services, and a vibrant partner ecosystem. The company targets medium to large enterprises and developers requiring scalable CMS solutions. Market positioning is strong due to a large community, extensive third-party extensions, and endorsements from notable customers such as government agencies and universities. Revenue streams likely include software licenses, support packages, and consulting services. The presence of a dedicated store and partner programs indicates a mature ecosystem fostering growth and customer retention. Strategic partnerships and community engagement are key competitive advantages, supporting sustained market presence and innovation.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS usage and cookie consent mechanisms aligned with privacy regulations. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No explicit security policies or incident response contacts are published, which could hinder rapid response to security incidents. The site does not expose sensitive data or use vulnerable libraries based on the analysis. Privacy compliance is evident but could be improved with more transparency on data retention and incident handling. Overall, the security maturity is adequate for a technology company but would benefit from enhanced security documentation and header implementation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting of security issues.
  4. Enhance accessibility features to meet higher standards and improve user inclusivity.
  5. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to increase trust.

Technical notes

Notes

The website is built on the ASP.NET framework, utilizing jQuery and various third-party libraries for UI and analytics. It integrates marketing automation tools such as Marketo and tracking services including Google Analytics and Twitter conversion pixels. The site is mobile responsive with a modern design and clear navigation structure. Performance is moderate, with potential improvements in load times and accessibility. The absence of detailed hosting information limits full infrastructure assessment. The technical implementation supports a robust CMS platform with extensibility and multi-site management capabilities. Opportunities exist to modernize security configurations and enhance compliance features.
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.
