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

Phantom is a well-established cryptocurrency wallet platform that supports multiple blockchains including Solana, Ethereum, Bitcoin, Base, and Sui. It offers users the ability to buy, trade, store, and manage crypto assets and NFTs with a focus on security and user control. The platform boasts over 15 million users and integrates with hardware wallets like Ledger to enhance security. The website is professionally designed, mobile-optimized, and provides a seamless user experience with clear navigation and rich multimedia content. Technically, the site uses modern web technologies including React, Cloudflare for DNS and CDN, and analytics tools such as Google Tag Manager, Datadog, and RudderStack. Security posture is strong with HTTPS enforced and domain transfer protections in place, though DNSSEC is not enabled. Privacy compliance is good with a comprehensive privacy policy and terms of service, but lacks a cookie consent mechanism and explicit incident response contacts. Overall, Phantom presents a trustworthy and mature digital presence in the crypto wallet market.

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

6 findings rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Phantom occupies a strong position in the cryptocurrency wallet sector, targeting crypto users and investors seeking multi-chain wallet solutions. Its business model centers on providing a self-custodial wallet service with additional features like NFT marketplace access and token swapping. The company leverages partnerships and integrations such as Ledger hardware wallets and maintains active engagement through social media and support channels. The domain's long registration history and consistent branding reinforce its credibility. Revenue streams likely include transaction fees, premium features, or partnerships. Growth indicators include a large user base and continuous product updates. Strategic observations suggest focusing on enhancing privacy compliance and formalizing vulnerability disclosure processes to maintain trust and regulatory alignment.

Security posture

Phantom demonstrates a mature security posture with enforced HTTPS, clientTransferProhibited domain status, and emphasis on self-custody to minimize centralized risk. The platform integrates scam detection and supports hardware wallet connections, enhancing user security. However, the absence of DNSSEC and a published security.txt file indicates room for improvement in DNS security and vulnerability management transparency. No exposed sensitive data or vulnerable libraries were detected. Incident response contact information is not publicly available, which could hinder timely reporting and mitigation of security issues. Compliance with GDPR is indicated by the privacy policy, but cookie consent mechanisms are missing, representing a compliance gap. Overall, the security maturity is high but could benefit from formalized disclosure and DNS security enhancements.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Implement a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  3. Publish a security.txt file to provide clear vulnerability disclosure and incident reporting channels.
  4. Add explicit incident response contact information (e.g., security@ or abuse@ email addresses) on the website.
  5. Regularly review and update privacy and security policies to maintain compliance and user trust.

Technical notes

Notes

The website is built on a modern React-based frontend with Cloudflare providing DNS and CDN services, ensuring fast and reliable content delivery. Analytics and monitoring are handled via Google Tag Manager, Datadog, and RudderStack, indicating a mature data collection and performance monitoring setup. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and Open Graph data. No common CMS platforms were detected, suggesting a custom or proprietary content management solution. Performance is fast with preloading of fonts and images. Technical risks are minimal but include the lack of DNSSEC and cookie consent mechanisms. The infrastructure supports scalability and security but should address minor compliance and transparency gaps to reduce potential operational risks.
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.
