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

Esri's ArcGIS Online platform provides a comprehensive SaaS solution for geographic information system (GIS) services, enabling users to connect people, locations, and data through interactive maps and spatial analysis tools. The website reflects a mature enterprise-level service with a clear focus on GIS professionals and organizations requiring mapping and data visualization capabilities. The platform is positioned as a leading geospatial technology provider with a strong brand presence and consistent messaging. Technically, the website employs a mature JavaScript stack including the Dojo Toolkit and Esri's own JS API, alongside modern Calcite components for UI. While the technology is somewhat dated, it remains functional and optimized for web and mobile use. The site demonstrates good SEO and basic accessibility features, though there is room for improvement in accessibility and performance optimization. From a security perspective, the site uses HTTPS and avoids exposing sensitive data in the HTML. However, explicit security headers are not evident in the provided data, and there is no visible incident response or vulnerability disclosure information. Privacy compliance is strong with comprehensive policies linked, though no cookie consent mechanism is detected. The absence of direct contact emails or phone numbers on the main page suggests a controlled communication approach via official Esri channels. Overall, the website is trustworthy and professional, with a solid business credibility score. The missing WHOIS data is a notable anomaly but likely due to registry privacy or restrictions rather than malicious intent. Strategic recommendations include enhancing security headers, publishing incident response details, improving accessibility, and implementing cookie consent mechanisms to further strengthen compliance and user trust.

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 as a key player in the geospatial technology sector, offering ArcGIS Online as a cloud-based GIS platform. The business model centers on SaaS delivery of mapping, spatial analysis, and data sharing services targeted at government, enterprise, and professional GIS users. The company benefits from a strong brand reputation and a broad partner ecosystem, including trust and legal resources prominently linked on the site. Revenue streams likely include subscriptions and enterprise licensing. The platform's integration with Esri's broader geospatial offerings positions it competitively in the market. Growth indicators include continuous platform updates and a focus on data-driven mapping solutions. The absence of direct contact details on the site suggests a centralized customer support model, reinforcing enterprise-grade service delivery.

Security posture

The current security posture is moderate to good. HTTPS is used, ensuring encrypted communications. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the HTML content. The absence of explicit incident response or vulnerability disclosure pages limits transparency and user confidence in security readiness. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are missing, which may be a compliance gap. Overall, the site demonstrates a baseline security maturity appropriate for an enterprise SaaS platform but would benefit from enhanced security controls and transparency.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Publish a dedicated vulnerability disclosure policy and incident response contact information to improve transparency and user trust.
  3. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  4. Enhance website accessibility features to meet WCAG standards and improve user experience for all users.
  5. Regularly audit and update third-party libraries and frameworks to mitigate potential vulnerabilities and technical debt.

Technical notes

Notes

The website uses a mature JavaScript stack centered on the Dojo Toolkit and Esri's JavaScript API version 3.42, supplemented by Calcite Components for UI elements. The site is web and mobile optimized with responsive design elements. Performance is moderate, with potential for improvement through modernization of the tech stack and optimization of resource loading. The absence of a detected CMS suggests a custom or proprietary platform. Hosting details are not explicit but likely managed by Esri or a trusted provider. The site exhibits good SEO practices with meta tags and structured data (JSON-LD) for search engines. Accessibility is basic, indicating room for enhancement. Overall, the technical implementation supports a stable and professional user experience but could benefit from modernization and improved security 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.
