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

Envoyproxy.io is the official website for Envoy, an open source edge and service proxy designed primarily for cloud-native applications and microservices architectures. Originally developed by Lyft, Envoy has established itself as a leading technology in the service mesh and distributed proxy space, supported by a broad ecosystem including major technology companies such as Google, Microsoft, Netflix, and AWS. The website serves as a hub for documentation, downloads, community engagement, and training resources, reflecting a mature open source project with strong industry adoption. From a technical perspective, the website is built using modern web technologies including the Pelican static site generator, Bootstrap for responsive design, and integrates analytics tools such as Google Analytics and Google Tag Manager. The site is well-structured, mobile-optimized, and provides clear navigation to key resources. However, explicit privacy and cookie policies are not present in the analyzed HTML content, and no contact information or security policies are directly visible, which could be improved to enhance transparency and compliance. Security-wise, the site does not show signs of WAF or blocking mechanisms and does not expose sensitive data or vulnerable scripts in the homepage content. The absence of security headers and explicit privacy compliance documentation suggests room for improvement in security posture and regulatory adherence. The WHOIS data is unavailable due to privacy protection and malformed queries, but the website's association with Lyft and the Linux Foundation, along with its widespread use, supports its legitimacy. Overall, envoyproxy.io is a professional, credible, and technically sound website representing a significant open source project in the cloud-native ecosystem. Strategic enhancements in privacy disclosures, security headers, and contact transparency would further strengthen its trustworthiness and compliance profile.

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

8 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"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

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

Envoyproxy.io operates as an important entity within the technology sector, specifically targeting developers and enterprises deploying microservices and cloud-native applications. Its business model revolves around open source software development, community engagement, and corporate sponsorship, with Lyft as the founding organization and the Linux Foundation as a key steward. The project enjoys a strong market position as a leading service proxy and data plane solution, evidenced by adoption from top-tier technology companies. The website supports this ecosystem by providing comprehensive documentation, training, and community resources, fostering growth and collaboration. While revenue streams are not directly evident, the project's influence and partnerships suggest indirect monetization through enterprise support and ecosystem services.

Security posture

The security posture of envoyproxy.io is moderate. The website is accessible without WAF or blocking, indicating no overt security restrictions. No forms or user inputs are present on the homepage, reducing attack surface. However, the lack of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options is a notable gap. Privacy and cookie policies are absent from the analyzed content, which may impact GDPR and other regulatory compliance. Incident response and vulnerability disclosure information are not found, limiting transparency for security issues. The WHOIS data is privacy protected, which is common for open source projects but reduces registrant transparency. Overall, the site demonstrates basic security hygiene but would benefit from enhanced security headers, explicit privacy documentation, and published incident response contacts.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve regulatory compliance and user trust.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance protection against common web attacks.
  3. Provide clear contact information including security incident response and vulnerability disclosure channels.
  4. Regularly audit and update SSL/TLS configurations to ensure strong encryption and prevent vulnerabilities.
  5. Enhance transparency around data collection and retention practices related to analytics and tracking.

Technical notes

Notes

The website is built on a modern, static site architecture using Pelican, with responsive design powered by Bootstrap. It integrates Google Analytics and Google Tag Manager for user tracking and marketing insights. The site loads quickly and is mobile optimized, with clear navigation and structured content. No CMS or dynamic backend is detected, reducing complexity and attack surface. The absence of security headers and explicit privacy mechanisms are technical gaps. Hosting provider details are not evident from the HTML content. Overall, the technical implementation is solid for an open source project website, with opportunities to improve security and privacy features.
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.
