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

Consensys Software Inc is a leading blockchain software company focused on building tools, infrastructure, and research that power Ethereum, the foundation for a more secure and open economy. Founded in 2019 by Ethereum's co-creator, Consensys holds a strong market position with flagship products such as MetaMask, Linea Layer 2, and Infura. Their target audience includes developers, enterprises, and users interested in Ethereum and decentralized technologies. The company operates primarily in the technology sector with a large organizational size and a global reach. Technically, the website leverages modern frameworks like SvelteKit and Three.js, hosted on Cloudflare, and integrates multiple analytics and marketing tools including HubSpot, Google Tag Manager, and Facebook Pixel. The site is well optimized for performance, mobile responsiveness, and accessibility, reflecting a mature digital infrastructure. From a security perspective, the site enforces HTTPS, employs standard security headers, and implements cookie consent mechanisms aligned with GDPR compliance. However, DNSSEC is not enabled, and there is no public security.txt or explicit incident response contact information, which could be improved. No critical vulnerabilities or exposed sensitive data were detected. Overall, the website and business demonstrate a high level of professionalism, trustworthiness, and compliance. The domain registration details are consistent with the company's claims, reinforcing legitimacy. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, and enhancing incident response transparency to further strengthen security posture and trust.

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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Consensys is positioned as a pivotal player in the Ethereum ecosystem, offering a comprehensive portfolio of products and services that cater to both end-users and developers. Their business model revolves around software development, infrastructure provisioning, and research contributions to Ethereum protocol upgrades. Revenue streams likely include product licensing, developer tools, staking services, and enterprise solutions. The company maintains strategic partnerships and subsidiaries such as MetaMask and Linea, enhancing its ecosystem influence. Growth indicators include a large user base for MetaMask and active participation in Ethereum upgrades. The company’s transparent communication and extensive product suite underscore a robust market presence and competitive advantage.

Security posture

The security maturity of Consensys.io is strong, with HTTPS enforced and multiple security headers implemented. The presence of cookie consent banners and privacy policies indicates compliance with data protection regulations like GDPR. No critical security issues or vulnerabilities were identified in the website content or configuration. However, the absence of DNSSEC and a publicly available security.txt file are minor gaps. Incident response contact details are not explicitly provided, which could hinder rapid communication during security events. Overall, the security posture is solid but can be enhanced by addressing these gaps and maintaining continuous security audits.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file at the root of the domain to facilitate vulnerability disclosures.
  3. Provide explicit incident response contact information on the security or contact pages.
  4. Regularly review and update third-party scripts and tracking pixels to minimize security risks.
  5. Consider obtaining and displaying relevant security certifications to enhance trust.

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.
