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

OpenScan.ai operates as a blockchain explorer dedicated to the XDC Network, providing users with comprehensive tools to explore transactions, addresses, tokens, NFTs, and DeFi activities. The platform targets blockchain users, developers, and investors interested in the XDC ecosystem. It offers a range of services including transaction tracking, token analytics, contract verification, and developer APIs, positioning itself as a niche but important player in the blockchain data services market. Technically, the website leverages modern web technologies such as React.js and Bootstrap, hosted and registered via Cloudflare, ensuring a reliable and secure infrastructure. The site demonstrates good performance and mobile optimization, with a clean and professional design that facilitates user navigation and engagement. From a security perspective, the site benefits from HTTPS enforcement, strong security headers, and domain transfer protections. However, it lacks publicly available privacy and cookie policies, as well as explicit incident response or vulnerability disclosure information, which are important for regulatory compliance and user trust. Overall, OpenScan.ai presents a solid technical and business foundation with moderate security maturity. To enhance trust and compliance, it should implement comprehensive privacy and cookie policies, provide clear contact and incident response channels, and enable DNSSEC for improved DNS security.

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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

OpenScan.ai serves a specialized market segment within the blockchain industry, focusing on the XDC Network. Its competitive advantage lies in offering detailed blockchain data and analytics tailored to this network, supported by developer-friendly APIs and contract verification tools. The business model appears to be service-oriented, potentially monetizing through API plans and value-added blockchain data services. The platform's partnerships with related blockchain projects and presence on social media channels like Twitter and Telegram indicate active community engagement and ecosystem integration. Growth indicators include a relatively recent domain registration and expanding service offerings such as DeFi and NFT tracking.

Security posture

The website exhibits a good security posture with HTTPS enabled, robust security headers, and domain transfer restrictions. The use of Cloudflare for DNS and registrar services adds an additional layer of security and reliability. However, the absence of privacy and cookie policies, lack of a vulnerability disclosure program, and missing incident response contact details represent compliance and operational gaps. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The site would benefit from implementing DNSSEC and publishing security policies to improve transparency and regulatory adherence.

Recommendations

  1. Publish comprehensive privacy and cookie policies to address GDPR and other privacy regulations.
  2. Implement a cookie consent mechanism to inform users and obtain consent for tracking.
  3. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  4. Provide clear contact information for security incidents, including security@ or abuse@ email addresses.
  5. Establish and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a modern React.js framework with Bootstrap for responsive design and Highcharts for data visualization. It uses Cloudflare for DNS and domain registration, ensuring reliable hosting and security features. Performance is moderate with good mobile optimization and basic accessibility features. SEO is basic but includes essential meta tags and Open Graph data. The site lacks a CMS indication, suggesting a custom or static site build. Technical risks are minimal but could be reduced by enabling DNSSEC and improving privacy compliance. The infrastructure supports scalability and integration with blockchain data sources effectively.
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.
