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

Alchemy is a leading web3 development platform that empowers developers and enterprises to build blockchain applications with ease. The platform offers a comprehensive suite of APIs, smart wallet solutions, transaction simulation, and an intelligent blockchain engine called Cortex. Alchemy targets a broad audience from beginner developers to large enterprises, positioning itself as a critical infrastructure provider in the blockchain ecosystem. The website demonstrates strong branding, professional design, and detailed technical content, reflecting a mature digital presence. Technically, the site leverages modern frameworks like Next.js and is hosted on Vercel, ensuring fast performance and mobile optimization. Security posture is solid with HTTPS and no exposed sensitive data, though some security headers and policies could be improved. The absence of WHOIS data for the domain introduces some uncertainty about domain registration legitimacy, but the presence of reputable partners and customer testimonials supports business credibility. Privacy and cookie policies are not clearly found, indicating room for compliance improvement.

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. 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 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Twitter, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

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

Alchemy operates in the blockchain technology sector, providing essential infrastructure and developer tools for the web3 ecosystem. Its business model revolves around platform services including APIs for blockchain data, smart wallets, and developer tooling. The company has established partnerships with notable crypto projects and enterprises, enhancing its market position. The platform's focus on scalability, reliability, and developer experience gives it a competitive advantage. Growth indicators such as transaction volumes and user metrics are prominently displayed, signaling strong adoption. The company targets developers, startups, and large enterprises, indicating a broad customer base. Strategic partnerships with projects like Polygon and Zerion further solidify its ecosystem presence.

Security posture

The website demonstrates a good security posture with HTTPS enforced and no visible exposure of sensitive information. However, the lack of explicit security headers such as Content-Security-Policy and absence of published security policies or incident response contacts are gaps. No vulnerability disclosures or security.txt files were found, which could enhance transparency and trust. The site uses third-party analytics and marketing scripts loaded asynchronously, which is standard but requires ongoing monitoring for privacy compliance. Overall, the security maturity is moderate to good but could benefit from formalized policies and enhanced header configurations.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers like Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  3. Publish a security policy and incident response contact information to demonstrate readiness and transparency.
  4. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Verify and update WHOIS domain registration information to ensure transparency and legitimacy.

Notes

The website is built on a modern tech stack including React and Next.js, hosted on Vercel, and uses DatoCMS for content management. Performance is optimized with preloading of fonts and images, and asynchronous loading of analytics scripts. The site is mobile responsive with excellent design and accessibility features. SEO is supported by comprehensive meta tags and Open Graph data. The technical infrastructure supports a high-quality user experience and scalable platform delivery. Opportunities exist to enhance security headers and formalize privacy compliance mechanisms.
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.
