Risk levelLow

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

Mantle Network is a cutting-edge Ethereum Layer-2 blockchain platform focused on delivering high throughput, low fees, and enhanced security through modular architecture and zero-knowledge proofs. Positioned as Ethereum's largest L2 network with ZK validity proofs, Mantle offers a token-governed ecosystem with a treasury and a roadmap driven by community governance. The platform targets developers, DeFi users, and blockchain projects seeking scalable and secure infrastructure. Technically, the website leverages modern frameworks like Next.js and Tailwind CSS, hosted on Vercel, ensuring fast performance and excellent mobile optimization. Security posture is strong with HTTPS, security headers, and a public bug bounty program, though explicit security policies and incident response contacts are not published. Privacy compliance is partially met with a privacy policy but lacks a cookie consent mechanism. Overall, Mantle Network presents a professional, trustworthy, and technically mature presence in the blockchain space.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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

Mantle Network operates in the blockchain technology sector, focusing on Ethereum Layer-2 scaling solutions. Its business model revolves around providing infrastructure and ecosystem services, including token governance, treasury management, and developer grants. The network benefits from strategic partnerships with BitDAO, Bybit, and venture capital firms like Polychain and Dragonfly, enhancing its market position. Revenue streams likely include token economics, ecosystem growth incentives, and partnerships. The target customers are blockchain developers, DeFi users, and institutional participants. Growth indicators include a $200M EcoFund, active governance forums, and integration with major DeFi and CeFi platforms. The company maintains a strong community presence via social media and developer tools, positioning itself as a leading modular L2 solution.

Security posture

Mantle Network demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and a public bug bounty program hosted on Immunefi. The absence of exposed sensitive data and use of modern web technologies reduce attack surface risks. However, the lack of a published formal security policy, incident response plan, and dedicated security contact channels limits transparency and readiness perception. Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. No vulnerabilities or suspicious patterns were detected in the website content or WHOIS data. Overall, the security maturity is high but could be improved by formalizing policies and enhancing user-facing security communications.

Recommendations

  1. Implement a visible cookie consent banner to comply with GDPR and other privacy regulations.
  2. Publish a formal security policy and incident response plan accessible from the website footer.
  3. Add a security.txt file to facilitate vulnerability disclosures and improve transparency.
  4. Provide explicit security contact information such as security@ or abuse@ email addresses.
  5. Enhance accessibility features to meet higher standards and improve user inclusivity.

The website is built using modern web technologies including Next.js and Tailwind CSS, hosted on Vercel, ensuring fast load times and excellent mobile responsiveness. The tech stack supports modular and scalable development, suitable for a blockchain infrastructure provider. SEO is well addressed with proper meta tags and Open Graph data. Analytics are implemented via Google Analytics and a third-party cookie analytics script, indicating moderate user tracking. No CMS was detected, suggesting a custom or static site generation approach. The site uses multiple external integrations for community engagement and developer support. Technical risks are minimal, with no outdated or vulnerable libraries detected. Opportunities exist to improve privacy compliance and security transparency.
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.
