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

ArcGIS, operated by Esri, is a leading global geographic information system platform offering mapping and spatial analytics software and services. The website serves as a portal for ArcGIS Online and related GIS products targeting GIS professionals, developers, enterprises, and government agencies. The business model is primarily SaaS and software licensing, positioning Esri as a dominant player in the GIS technology sector. Technically, the website employs a modern JavaScript stack including the ArcGIS JS API, Dojo Toolkit, and Calcite Components. The site is web-based with moderate performance and basic mobile optimization. SEO and accessibility features are present but could be improved. The site uses HTTPS and includes links to privacy and legal policies, indicating a reasonable level of digital maturity. From a security perspective, the site shows good baseline practices such as HTTPS usage and no visible sensitive data exposure. However, security headers are not evident in the provided data, and there is no published security policy or incident response information. The WHOIS data is unavailable, which is unusual but likely due to registry restrictions or privacy protection. Overall, the security posture is moderate with room for improvement in transparency and technical controls. The overall risk assessment is low given the professional nature of the site and its association with a reputable enterprise. Strategic recommendations include enhancing security headers, publishing security and incident response policies, implementing cookie consent mechanisms, and adding vulnerability disclosure information to improve trust and compliance.

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's ArcGIS platform holds a strong market position as a leader in GIS technology, serving a broad range of sectors including government, enterprise, and developers. The business model focuses on SaaS and licensing, generating revenue through subscriptions and software sales. The target customers are GIS professionals and organizations requiring spatial analytics. The company maintains a robust partnership ecosystem and brand consistency. Growth indicators include continuous platform updates and integration of modern web technologies. The website reflects a professional and enterprise-grade operation with clear trust signals such as privacy and legal policies.

Security posture

The security maturity level is moderate. The site uses HTTPS and avoids exposing sensitive data in the HTML. However, the absence of security headers and published security policies indicates gaps in defense-in-depth and transparency. There is no visible incident response or vulnerability disclosure information, which could hinder timely security issue reporting and resolution. Compliance with GDPR is implied through the privacy policy, but cookie consent mechanisms are missing. The WHOIS data unavailability is a concern but likely due to privacy or registry restrictions rather than malicious intent. Overall, the security culture appears professional but could benefit from enhanced communication and technical controls.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish a detailed security policy and incident response plan accessible from the website.
  3. Add a cookie consent banner or mechanism to comply with privacy regulations and improve user transparency.
  4. Establish and publicize a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance mobile optimization and accessibility features to improve user experience and compliance.

Technical notes

Notes

The website leverages a mature JavaScript technology stack including the ArcGIS JS API and Dojo Toolkit, indicating a specialized GIS platform infrastructure. The use of Calcite Components suggests adoption of modern UI frameworks. Performance is moderate with room for improvement in mobile responsiveness and accessibility. The absence of CMS detection suggests a custom or proprietary platform. Hosting provider details are not evident. Technical risks include missing security headers and limited SEO optimization. Modernization opportunities include enhancing accessibility, SEO, and security controls to align with enterprise best practices.
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.
