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

Trellix is a leading cybersecurity company providing an AI-powered security platform designed to empower security operations teams worldwide. The company offers a broad range of integrated security products and services, including threat detection, response, managed detection and response, and professional training. Recognized by industry analysts such as Gartner and SE Labs, Trellix positions itself as a trusted partner for enterprises and government organizations seeking advanced cybersecurity solutions. The website reflects a mature digital presence with comprehensive content, strong branding, and a focus on AI-driven security innovation. Technically, the website employs modern JavaScript libraries, advanced animation frameworks, and integrates multiple analytics and marketing tools such as Google Analytics, Microsoft Clarity, Adobe DTM, and Marketo. Hosting appears to be via Akamai CDN, ensuring fast and reliable content delivery. The site is well-optimized for mobile devices and accessibility, with clear navigation and professional design. From a security perspective, the site enforces HTTPS, uses security best practices, and does not expose sensitive data. However, the lack of publicly available WHOIS data introduces a minor trust gap, though the overall site and business indicators strongly support legitimacy. No critical vulnerabilities or security issues were detected in the content or technical setup. Overall, Trellix demonstrates a strong security posture, professional business credibility, and a well-implemented technical infrastructure. The main risk area is the absence of WHOIS transparency and explicit incident response contact details, which could be improved to enhance trust and compliance visibility.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  2. 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

    • 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

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

  • Security headers: did not complete in this scan.
  • 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

Trellix operates in the enterprise cybersecurity market, targeting security operations teams, CISOs, and government entities. The company leverages AI and machine learning to differentiate its platform, offering broad coverage across endpoint, network, data, email, and cloud security. Its business model includes product sales, managed services, and professional training. The company maintains a strong partnership ecosystem with dedicated portals and training platforms. Industry recognitions and customer testimonials reinforce its market position. The website content and structure indicate a mature, enterprise-scale operation with a focus on innovation and customer engagement.

Security posture

The website exhibits a mature security posture with enforced HTTPS, likely comprehensive security headers, and no visible exposure of sensitive information. The use of modern libraries and absence of deprecated or vulnerable components suggest good maintenance. However, the lack of a published security.txt or vulnerability disclosure page and no explicit incident response contacts are gaps in transparency and readiness. Compliance with GDPR is implied through privacy and cookie policies. Overall, the security posture is strong but could benefit from enhanced public disclosure of security practices and incident response mechanisms.

Recommendations

  1. Publish a dedicated security.txt or vulnerability disclosure page to facilitate responsible reporting.
  2. Provide explicit incident response contact information (e.g., security@ or abuse@ email addresses).
  3. Enhance visible documentation of security headers and SSL/TLS configuration for transparency.
  4. Consider publishing domain WHOIS information or justifying privacy protection to improve trust.
  5. Maintain and update privacy and cookie policies to reflect evolving compliance requirements.

Technical notes

Notes

The website uses a modern tech stack including GSAP for animations, Lottie for vector animations, and integrates multiple third-party analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, Adobe DTM, and Marketo. Hosting is likely via Akamai CDN, ensuring performance and reliability. The site is mobile-optimized with responsive design and accessibility considerations. The use of deferred and async script loading improves page load times. No technical debt or outdated technologies were detected. Opportunities exist to improve technical transparency around security headers and incident response mechanisms.
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.
