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

ZKM is a small US-based technology company founded in 2023, specializing in open-source zero-knowledge proof infrastructure and blockchain interoperability solutions. Their flagship product, the zkMIPS virtual machine, supports verifiable computing across multiple blockchain ecosystems and IoT devices, aiming to enable instant, secure transactions and unified native liquidity across blockchains. The company positions itself as an innovator in Layer 2 scaling and hybrid rollup technologies, targeting blockchain developers, zero-knowledge researchers, and IoT engineers worldwide. Technically, the website is built on modern web technologies including Webflow CMS, Google Tag Manager, and uses advanced multimedia content hosted on Dropbox. The site is mobile-optimized, fast-loading, and well-structured with comprehensive metadata and SEO practices. Security measures include HTTPS, Google reCAPTCHA, and controlled script loading, though some security headers and explicit security policies are absent. The security posture is solid but could be improved by publishing dedicated security and incident response policies, implementing security headers, and adding a vulnerability disclosure program. Privacy compliance is supported by a comprehensive privacy policy and terms of service, but lacks an explicit cookie consent mechanism. WHOIS data is unavailable due to privacy protections, which is common for tech startups, but the website content and business information support legitimacy. Overall, ZKM presents a professional, trustworthy, and technically mature web presence with a strong focus on cutting-edge blockchain technology. Strategic improvements in security transparency and privacy mechanisms would enhance trust and compliance further.

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

5 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 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

Business profile

ZKM operates in the blockchain technology sector with a focus on zero-knowledge proofs and Layer 2 scaling solutions. Their open-source business model offers free infrastructure tools and paid proving services, targeting developers and researchers in the blockchain ecosystem. The company has secured funding from notable investors such as OKX Ventures and Amber Group, indicating strong market confidence. Their active presence on multiple social and developer platforms fosters community engagement and ecosystem growth. The company’s innovative hybrid rollup technology and zkMIPS VM provide competitive advantages in interoperability and security, positioning ZKM as a promising player in the evolving blockchain infrastructure market.

Security posture

ZKM demonstrates a good security maturity level with HTTPS enforcement and use of Google reCAPTCHA to protect forms. No sensitive data exposure or vulnerable libraries were detected in the website content. However, the absence of explicit security policies, incident response plans, and security headers like Content-Security-Policy and Strict-Transport-Security indicates room for improvement. No vulnerability disclosure or security.txt files were found, which could limit external security collaboration. Privacy policies are comprehensive and GDPR compliant, but cookie consent mechanisms are missing. Overall, the security posture is solid but would benefit from enhanced transparency and formalized security governance.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a vulnerability disclosure program and security.txt file to encourage responsible reporting.
  4. Introduce a cookie consent mechanism to comply fully with GDPR and enhance user privacy.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website leverages modern web technologies including Webflow CMS, Google Tag Manager, and Swiper.js for interactive content. It uses Google Fonts and hosts multimedia content on Dropbox, ensuring fast and responsive user experience. The site is well-structured with comprehensive metadata, Open Graph tags, and JSON-LD structured data for SEO and social sharing. Mobile optimization and accessibility are excellent. The technical stack is appropriate for a technology startup, with no significant technical debt or performance issues detected. Opportunities exist to enhance security headers and formalize privacy consent mechanisms to align with best practices.
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.
