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

Esri's ArcGIS Online platform is a leading enterprise geospatial service that enables users to connect people, locations, and data through interactive maps and spatial analysis tools. The website reflects a mature SaaS business model targeting GIS professionals and organizations requiring advanced mapping capabilities. The platform is positioned strongly in the geospatial technology market with a comprehensive suite of services and a consistent brand presence. Technically, the website employs a combination of legacy Dojo toolkit and modern Calcite web components, indicating a blend of mature and contemporary technologies. The site is moderately optimized for performance and mobile use, with basic accessibility and SEO features. The absence of explicit cookie consent mechanisms and some security headers suggests areas for improvement in compliance and security hardening. From a security perspective, the site uses HTTPS and does not expose sensitive data in the HTML content. However, the lack of visible security headers and vulnerability disclosure policies indicates room for enhancement in security posture and transparency. The WHOIS data is unavailable or protected, which is not uncommon for large enterprises but requires cautious interpretation. Overall, the site demonstrates a high level of professionalism and trustworthiness. Strategically, the site would benefit from implementing explicit cookie consent, publishing vulnerability disclosure and incident response contacts, and enhancing security headers to align with best practices. These steps would improve compliance, user trust, and resilience against emerging threats.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

  3. 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

Esri operates ArcGIS Online as a flagship geospatial platform serving a global market of GIS professionals and organizations. The business model centers on SaaS delivery of mapping, data visualization, and spatial analytics tools. Esri's market position is strong, supported by a well-known brand and comprehensive service offerings. The company targets sectors requiring geospatial intelligence, including government, environmental, transportation, and utilities. The website's external links and trust center reinforce a mature partnership and compliance ecosystem. Growth indicators include continuous platform updates and integration of modern web technologies. Strategic partnerships and a global presence underpin Esri's competitive advantage in the geospatial technology space.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. 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 vulnerability disclosure or incident response contacts are published, limiting transparency and user confidence in security responsiveness. GDPR compliance is implied through a comprehensive privacy policy, but cookie consent mechanisms are missing. The security culture appears professional but could be enhanced by adopting industry best practices for web security and incident management. No critical vulnerabilities or malware indicators were detected in the provided content.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Add a cookie consent banner and detailed cookie policy to improve privacy compliance and user transparency.
  3. Publish a vulnerability disclosure policy and incident response contact information to enhance security transparency and trust.
  4. Conduct regular security audits and update legacy JavaScript libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses a hybrid technology stack combining the Dojo JavaScript toolkit (version 3.42) and modern Calcite web components (version 2.12.2). This indicates a transition phase from legacy to modern frameworks. The site loads multiple external scripts from js.arcgis.com, suggesting reliance on Esri's CDN infrastructure. Performance is moderate with no explicit indicators of optimization or degradation. Mobile optimization is good, supported by responsive design elements. Accessibility is basic, with room for improvement in ARIA roles and keyboard navigation. SEO is basic with meta tags present but no Open Graph or Twitter Card tags detected. Hosting provider details are not available from the provided data. Overall, the technical implementation is stable but could benefit from modernization and enhanced performance tuning.
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.
