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

RISC Zero is a technology company specializing in zero-knowledge proof technology, offering a high-performance, cost-effective zero-knowledge virtual machine (zkVM) platform. The company targets developers and technology firms seeking to build scalable zero-knowledge applications across blockchain ecosystems. Their market position is strengthened by a broad partnership network and open-source approach, positioning them as a leading zkVM provider. Technically, the website is built on a modern stack including Next.js and hosted on AWS infrastructure, ensuring fast performance and mobile optimization. The site employs HTTPS and security headers, reflecting a solid security posture. However, some compliance elements such as privacy and cookie policies are missing, which could be improved. Security-wise, the site demonstrates good practices with no evident vulnerabilities or exposed sensitive data. The domain registration is consistent and transparent, with protective domain status flags. Overall, the risk level is low, but enhancements in privacy compliance and incident response transparency are recommended. Strategic recommendations include publishing comprehensive privacy and cookie policies, enabling DNSSEC for DNS security, and providing clear vulnerability disclosure and incident response information to enhance trust and compliance.

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.

Dark web exposure

Add-on

Leaked records that mention risczero.com, from OffSeq Breach.

No leaked records found

Breach holds no records for risczero.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

RISC Zero operates in the cutting-edge technology sector focused on zero-knowledge proofs and zkVMs. Their business model revolves around providing developer tools and platform technology to enable scalable zero-knowledge applications. The company has established a strong ecosystem of partners across blockchain and technology domains, indicating robust market positioning and growth potential. Revenue streams likely include platform partnerships, developer services, and possibly enterprise solutions. The target customer segments are developers, blockchain projects, and enterprises requiring privacy-preserving computation. The company was founded in 2022 and maintains a medium-sized operational scale with a professional online presence.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented. No sensitive data leakage or vulnerable libraries were detected in the analyzed content. However, the absence of DNSSEC reduces DNS security resilience. The lack of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. The minimal use of tracking and privacy-conscious analytics indicates a positive privacy culture. Overall, the security maturity is good but can be improved by formalizing security policies and enabling DNSSEC.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve privacy compliance and user trust.
  2. Implement a cookie consent mechanism if cookies or tracking are used to comply with GDPR and other regulations.
  3. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  4. Add explicit security incident response and vulnerability disclosure information, including contact channels.
  5. Consider obtaining and displaying relevant security certifications to strengthen trust and credibility.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, hosted on AWS infrastructure. It demonstrates fast loading times, mobile responsiveness, and good SEO practices with proper meta tags and Open Graph data. The use of HubSpot forms indicates integration with marketing automation tools. No CMS was detected, suggesting a custom or static site approach. The technical infrastructure is robust with minimal technical debt visible. Opportunities exist to enhance DNS security and formalize compliance-related technical implementations.
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.
