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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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 X-Frame-Options header

      Prevents clickjacking attacks

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

    • 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';…

  3. 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

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.

Business context

Business profile

OpenScan.ai operates in the blockchain technology sector, offering Explorer as a Service (EaaS) to new and established blockchain networks. Its business model focuses on providing customizable, AI-powered blockchain explorers that support multiple EVM-compatible chains and testnets. The platform's competitive advantages include AI-driven intelligence, multi-chain readiness, modular open-source architecture, and advanced analytics. The company targets blockchain developers, enterprises, and ecosystem builders, emphasizing transparency and developer empowerment. Testimonials from founders of XDC Network, Wanchain, and Velas Network indicate strong partnerships and ecosystem integration. The company is newly established in 2024, with a small team and a focus on innovation and scalability. Growth indicators include multi-network support and a service offering that addresses emerging blockchain infrastructure needs.

Security posture

OpenScan.ai demonstrates a good security posture with mandatory HTTPS and domain registration protections such as clientDeleteProhibited status. However, the website lacks explicit security headers like Content-Security-Policy and Strict-Transport-Security, which are recommended to mitigate common web vulnerabilities. There is no published security policy, incident response plan, or vulnerability disclosure program visible on the site, which limits transparency and readiness for security incidents. Privacy compliance is partial, with a privacy policy present but no cookie consent or GDPR-specific mechanisms. No sensitive data exposure or vulnerable libraries were detected. Overall, the security maturity is moderate, suitable for a startup but requiring enhancements to meet enterprise-grade standards.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a detailed security policy and incident response plan on the website.
  4. Add a cookie consent banner and mechanisms to comply with GDPR and other privacy regulations.
  5. Establish a vulnerability disclosure program and publish a security.txt file to improve transparency and community trust.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring server-side rendering and good SEO performance. The use of AOS library adds smooth animations enhancing user experience. Hosting is supported by Cloudflare DNS, contributing to fast loading times and reliability. The site is mobile-optimized with responsive design and accessibility considerations. No CMS was detected, indicating a custom or framework-based build. Performance is fast with preloading of fonts and images. Technical debt appears low, but the absence of some security best practices and privacy compliance features indicates areas for modernization. Overall, the technical infrastructure is solid and scalable for future growth.
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.
