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

Etherlink is a decentralized, EVM-compatible Layer-2 blockchain platform built on Tezos smart rollup technology. It aims to provide fast, fair, and nearly free transactions, enabling users to bridge assets, swap instantly, and explore decentralized applications with low fees and high speed. The platform targets developers, DeFi users, and blockchain enthusiasts seeking scalable and secure Layer-2 solutions. The website showcases a rich ecosystem of partners and integrations, emphasizing its commitment to interoperability and developer support. Technically, Etherlink employs modern web technologies including React and Next.js, hosted on Vercel, with integrations of analytics tools such as Google Tag Manager, Fathom Analytics, and PostHog. The site is well-optimized for performance and mobile responsiveness, with good SEO and accessibility basics. Security best practices are observed with HTTPS enforcement and multiple security headers, though explicit privacy and cookie policies are missing. From a security perspective, the site demonstrates a solid posture with no visible vulnerabilities or exposed sensitive data. However, the absence of formal security incident response and vulnerability disclosure policies, as well as missing contact information, represent areas for improvement. The WHOIS data is unavailable, which raises concerns about domain registration transparency and trustworthiness, though the website content and partner ecosystem suggest legitimacy. Overall, Etherlink presents as a promising blockchain Layer-2 project with a professional web presence and strong technical foundation. Strategic enhancements in privacy compliance, security transparency, and domain registration clarity would further strengthen its trust and credibility.

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

4 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 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';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Business context

Business profile

Etherlink positions itself as an innovative Layer-2 blockchain solution leveraging Tezos smart rollup technology to deliver fast, low-cost, and decentralized transactions. Its business model revolves around providing infrastructure and tools for developers and users to build and interact with decentralized applications and DeFi services. The platform's partnerships with notable blockchain projects and integrations indicate a growing ecosystem and collaborative approach.

Security posture

The website exhibits a mature security posture with HTTPS enforced and comprehensive security headers implemented, enhancing protection against common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of published privacy and cookie policies, absence of security incident response and vulnerability disclosure information, and missing direct contact channels for security concerns indicate gaps in compliance and transparency. These gaps could impact user trust and regulatory adherence, especially under GDPR and similar frameworks. The use of multiple third-party analytics and tracking services without clear privacy disclosures further highlights compliance risks. Overall, while technical security controls are strong, governance and policy transparency require enhancement to meet best practices fully.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit user consent mechanisms to improve GDPR compliance.
  2. Establish and publicly disclose a security incident response plan and vulnerability disclosure policy to enhance transparency and trust.
  3. Provide clear and accessible contact information, including security and general inquiry emails, to facilitate communication and support.
  4. Conduct accessibility audits and implement improvements to meet recognized standards and broaden user inclusivity.
  5. Regularly review and audit third-party scripts and analytics tools to minimize privacy risks and ensure compliance.

Technical notes

Notes

Etherlink's website is built using a modern React and Next.js framework, hosted on Vercel, ensuring fast performance and scalability. The site employs advanced front-end optimizations, including preloading of critical assets and responsive design for mobile devices. SEO is well-addressed with appropriate meta tags and Open Graph data. Analytics integration is comprehensive, utilizing Google Tag Manager, Fathom Analytics, PostHog, and Vercel Analytics, enabling detailed user behavior insights. Security headers are properly configured, and HTTPS is enforced, reflecting good security hygiene. However, the absence of a CMS suggests content updates may require developer involvement. The missing WHOIS data indicates potential domain registration issues that should be investigated to avoid operational risks. Overall, the technical infrastructure is robust, performant, and aligned with modern web standards.
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.
