Gartner is a leading global research and advisory company providing actionable insights, guidance, and tools to executives and their teams across multiple industries. The company offers expert guidance, consulting, conferences, and technology evaluation tools, targeting C-suite executives, IT leaders, and business leaders. Gartner maintains a strong market position as a trusted advisor with a comprehensive portfolio of services designed to support mission-critical business priorities. Technically, the Gartner website demonstrates a mature digital infrastructure leveraging modern technologies such as Google Tag Manager, Google Analytics, Dynatrace monitoring, and OneTrust for cookie consent management. The site is built on a robust CMS platform, likely Adobe Experience Manager, ensuring excellent performance, mobile optimization, and accessibility. The website's SEO and metadata are well implemented, supporting strong discoverability and user experience. From a security perspective, Gartner enforces HTTPS with strong SSL configurations and implements security best practices including reCAPTCHA and cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly available, representing an area for improvement.

The absence of WHOIS data is consistent with privacy protection practices common among large enterprises. The site is safe for general audiences and free from adult or questionable content.

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. 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.

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.

Notes

The website is built on a modern technology stack including JavaScript frameworks, Google Tag Manager, Google Analytics, Dynatrace monitoring, and OneTrust for consent management. The CMS is likely Adobe Experience Manager, supporting scalable content delivery and multi-language support. Performance is optimized with preloading fonts and asynchronous script loading. The site is mobile responsive and accessible, with good SEO metadata and structured navigation. Technical risks are minimal, but continuous monitoring of third-party dependencies and security headers is recommended to maintain a strong security posture.
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.
