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

ZERO Network is an Ethereum Layer 2 blockchain network developed by Zerion, integrated tightly with the Zerion Wallet to provide free crypto transactions leveraging ZK Stack technology. The website positions ZERO Network as a seamless, gas-free crypto experience targeting both end-users and developers with services including USDC transfers, NFT minting, cross-L2 bridging, and token swapping. The technical infrastructure is modern, utilizing Webflow CMS, video and Lottie animations, and minimal but effective analytics via Plausible. Security posture is good with HTTPS and no visible vulnerabilities, though explicit security headers and policies are absent. WHOIS data is privacy protected, common in crypto projects, but reduces transparency. Overall, the site is professional, well-branded, and trustworthy with room for improvement in privacy compliance and incident response disclosures.

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. 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

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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

ZERO Network operates in the blockchain technology sector as a Layer 2 Ethereum scaling solution integrated with Zerion Wallet, targeting over 500k Zerion users and crypto enthusiasts seeking zero gas fees. The business model focuses on providing free transactions and developer APIs to foster ecosystem growth. Partnerships with Highlight, Decent, and DODOEX indicate a collaborative approach to NFT analytics, bridging, and swapping services. The company leverages its parent brand Zerion for credibility and market reach. The website content and external links suggest a medium-sized, technology-focused entity with a clear growth and developer engagement strategy.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and no exposed sensitive data. However, it lacks explicit security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options, which are recommended to mitigate common web threats. No vulnerability disclosure or security.txt files are present, limiting transparency for security researchers. Privacy and cookie policies are missing, which may impact GDPR and other compliance requirements. Incident response contact information is not provided, reducing readiness for security incidents. Overall, the security maturity is good but can be enhanced by adding formal policies and headers.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to strengthen web security posture.
  3. Provide clear contact information for security incidents and consider publishing a security.txt or vulnerability disclosure policy.
  4. Increase WHOIS transparency if possible to improve domain trustworthiness and legitimacy perception.
  5. Regularly audit and update third-party scripts and dependencies to avoid potential vulnerabilities.

Technical notes

Notes

The website is built on Webflow CMS, leveraging modern web technologies such as HTML5 video, Lottie animations, and minimal JavaScript for analytics (Plausible). The site is mobile-optimized with responsive design and good accessibility features like focus-visible outlines. Performance is fast with efficient asset loading from CDN sources. SEO is supported by proper meta tags and Open Graph images. Hosting appears to be Webflow's infrastructure, providing reliable uptime and scalability. There is no evidence of legacy or vulnerable libraries. The technical implementation supports a smooth user experience and aligns well with the business goals.
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.
