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

Gartner is a leading global research and advisory company founded in 1979, providing actionable insights, guidance, and tools to executives and their teams to enable smarter decisions and stronger organizational performance. The website targets C-suite executives, IT and technology leaders, and business leaders across various industries, offering services such as expert guidance, consulting, conferences, and peer communities. The digital infrastructure is modern and robust, leveraging advanced analytics, monitoring, and A/B testing tools, with a responsive and well-structured design optimized for performance and accessibility. Security posture is strong with HTTPS enforcement, bot protection via reCAPTCHA, and monitoring via Dynatrace, although explicit security headers and public security policies could be improved. Overall, the site is professional, trustworthy, and compliant with privacy regulations, though WHOIS data is unavailable, likely due to privacy protection, which slightly impacts trust but is common for enterprises of this scale.

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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  3. 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Gartner holds a strong market position as a trusted advisor to enterprises worldwide, focusing on technology and business leadership sectors. Its business model revolves around subscription-based research, consulting services, conferences, and digital tools. The company maintains a broad partnership ecosystem and a well-established brand presence across multiple social media platforms. The website content and structure reflect a mature digital marketing strategy with clear segmentation by audience and industry. Growth indicators include extensive conference offerings and peer community engagement. The absence of WHOIS transparency is offset by strong brand signals and official channels.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of reCAPTCHA to mitigate automated abuse, and integration of Dynatrace for performance and security monitoring. Cookie consent mechanisms indicate privacy awareness and GDPR compliance. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options, and absence of a public vulnerability disclosure or security.txt file, represent areas for improvement. Incident response contact information is not publicly available, which could be enhanced to improve transparency and trust.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen browser security.
  2. Provide a publicly accessible security policy and incident response contact information to enhance transparency and trust.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.
  5. Enhance cookie consent mechanisms with detailed data retention and processing disclosures to improve privacy compliance.

Technical notes

Notes

The website is built on Adobe Experience Manager CMS, utilizing modern web technologies including JavaScript frameworks, Google Tag Manager, Google Analytics, Dynatrace monitoring, and AB Tasty for A/B testing. The site is optimized for fast loading and mobile responsiveness, with well-structured HTML and CSS. Performance is enhanced by preloading fonts and DNS prefetching. The technical stack is mature and supports a high-quality user experience. Opportunities exist to improve accessibility features and to document technical security controls more explicitly.
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.
