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

mETH Protocol, developed by Mantle, is a pioneering platform offering institutional-grade ETH liquid staking and restaking services. It provides users with value-accumulating receipt tokens (mETH and cmETH) that represent staked ETH and restaked positions across multiple protocols. The platform is positioned as the first fully vertically integrated staking and restaking protocol, targeting institutional investors and sophisticated crypto users. The ecosystem includes partnerships with reputable staking node operators and multiple security audits, enhancing its market credibility. Technically, the website leverages a modern React and Next.js stack, ensuring fast performance, excellent mobile optimization, and good accessibility. The use of LayerZero OFT Standard for cross-chain bridging adds to its technical sophistication. SEO and metadata are well implemented, supporting discoverability and user engagement. From a security perspective, the site enforces HTTPS and includes standard security headers, reflecting good security hygiene. However, it lacks a visible cookie consent mechanism and explicit security or incident response policies, which are important for regulatory compliance and user trust. No critical vulnerabilities or exposed sensitive data were detected. Overall, mETH Protocol presents a professional, trustworthy, and technically sound platform with strong business credibility. To further enhance its security posture and compliance, it should implement cookie consent, publish security policies, and provide clear contact information for incident reporting.

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. 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. 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

    • 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.

Technical appendix

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

Business context

Business profile

mETH Protocol occupies a unique niche in the ETH staking ecosystem by combining staking and restaking into a unified, vertically integrated protocol. Its business model revolves around providing liquid staking receipt tokens that can be leveraged in DeFi and centralized finance applications, enhancing capital efficiency. The governance token COOK empowers community participation in ecosystem decisions. The platform's partnerships with established staking operators and auditors indicate a robust operational foundation. The target market includes institutional investors and crypto treasury managers, evidenced by the large ETH treasury holdings and strategic content. Growth potential is supported by multi-chain bridging capabilities and integration with emerging restaking protocols like EigenLayer and Symbiotic.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no visible exposure of sensitive information. The presence of multiple third-party audits adds confidence in the underlying protocol's security. However, the absence of a published security policy, incident response plan, and vulnerability disclosure mechanism limits transparency and preparedness for security incidents. The lack of cookie consent and GDPR compliance indicators also represents a compliance gap. Overall, the security maturity is good but can be improved by formalizing policies and enhancing user privacy controls.

Recommendations

  1. Implement a visible cookie consent banner to comply with privacy regulations and improve transparency.
  2. Publish a dedicated security policy and incident response plan accessible from the website footer or documentation.
  3. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Add clear contact information for security incidents, including dedicated security or abuse email addresses.
  5. Enhance GDPR compliance by updating privacy policies with data retention and user rights information.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring fast load times and excellent mobile responsiveness. The use of LayerZero OFT Standard for token bridging indicates advanced blockchain integration capabilities. The site is well-structured with proper meta tags and SEO optimization. No CMS was explicitly detected, suggesting a custom or headless CMS approach. Hosting details are not explicit but performance and accessibility are strong. The analytics implementation uses a third-party script (cookie3.analytics) without a consent mechanism, which should be addressed. Overall, the technical infrastructure is robust with minor areas for improvement in privacy and compliance tooling.
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.
