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

OneMap is a comprehensive government mapping platform operated by the Singapore Land Authority, providing authoritative geographic and property data for Singapore. The website offers a wide range of interactive tools including property queries, land ownership information, transportation routes, drone no-fly zones, and nearby essential services. It serves both the general public and professionals requiring detailed spatial data. The platform is positioned as the official national mapping service, reflecting Singapore's commitment to accessible and accurate geospatial information. Technically, the website employs modern web technologies such as React 18, CesiumJS for 3D mapping, and various JavaScript libraries to deliver an interactive user experience. The site is mobile-optimized and includes accessibility features, though some improvements could be made. Performance is moderate due to the complexity of mapping features. Security is well-considered with HTTPS enforced and several security headers present, but could benefit from enhanced Content Security Policy and explicit cookie consent mechanisms. From a security perspective, the site shows a mature posture with no obvious vulnerabilities or exposed sensitive data. The lack of publicly available WHOIS data is typical for government domains and does not detract from the site's legitimacy. Privacy compliance is basic, with a privacy policy and terms of use available, but no cookie consent banner detected. Overall, the site is trustworthy and professional, reflecting its government ownership and public service mission. Strategically, OneMap is a critical infrastructure component for Singapore's digital government ecosystem, supporting various stakeholders with essential geospatial data. Continued enhancements in privacy compliance and security best practices will further strengthen user trust and regulatory alignment.

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.

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

OneMap operates as a government essential service under the Singapore Land Authority, targeting a broad audience including citizens, businesses, and government agencies. Its competitive advantage lies in its authoritative data and comprehensive toolset for geographic and property information. The business model is non-commercial, focused on public service and data transparency. Revenue streams are not applicable as it is government-funded. The platform integrates with other government services and partners such as the Civil Aviation Authority of Singapore and other agencies, enhancing its ecosystem. Growth indicators include ongoing feature development and a new beta version. The partnership ecosystem is strong with official government domains linked. Operationally, OneMap demonstrates stability and strategic importance within Singapore's digital infrastructure.

Security posture

The security posture of OneMap is robust, leveraging HTTPS and multiple security headers to protect user data and site integrity. No critical vulnerabilities or exposed sensitive information were detected in the HTML content. The use of nonce attributes on scripts suggests Content Security Policy implementation, though explicit CSP headers were not observed. Privacy policies and terms of use are clearly presented, but cookie consent mechanisms are absent, representing a compliance gap. Incident response and security contact information are not explicitly provided, which could be improved. Overall, the site reflects a mature security culture consistent with government standards but would benefit from enhanced privacy and incident response transparency.

Recommendations

  1. Implement a comprehensive Content Security Policy (CSP) header to mitigate XSS and related attacks.
  2. Add a cookie consent banner to comply with privacy regulations and improve user transparency.
  3. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response.
  4. Enhance accessibility features to meet higher compliance standards and improve user experience for all users.
  5. Provide explicit security and incident response contact information to strengthen trust and readiness.

Technical notes

Notes

The website uses a modern technology stack including React 18 for UI, CesiumJS for advanced 3D mapping, and various utility libraries such as Turf.js and FileSaver.js. The site is hosted on HTTPS with no mixed content detected. Performance is moderate due to the heavy use of mapping and visualization scripts. The site is mobile-optimized with responsive design elements and viewport meta tags. SEO is basic with meta descriptions and Open Graph tags present. No CMS was detected, suggesting a custom or government-managed platform. Technical risks are low but include potential improvements in security headers and privacy compliance. The infrastructure appears stable and suitable for the site's public service mission.
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.
