56/100

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

Yandex's JavaScript libraries page serves as a developer-focused resource providing access to various open source JavaScript frameworks and libraries hosted on Yandex servers. The website is well-established, reflecting Yandex's position as a leading Russian technology company with a strong developer ecosystem. The technical infrastructure leverages modern technologies such as React and integrates Yandex Metrika for analytics, demonstrating a mature digital presence. Security posture is solid with HTTPS enforced and no visible vulnerabilities, although explicit security policies and incident response contacts are not published on this page. Privacy compliance is limited due to the absence of privacy and cookie policies or consent mechanisms. Overall, the website is professional, trustworthy, and technically sound but could improve transparency and compliance documentation.

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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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: Facebook, Twitter, YouTube

      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

  • Security headers: did not complete in this scan.
  • 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

Yandex operates as a major technology entity in Russia, providing a broad range of services including developer tools like JavaScript libraries. The business model focuses on platform services and ecosystem support for developers. The website targets developers and technology professionals seeking reliable access to JavaScript resources. Yandex's market position is strong, supported by its long domain age and verified registration. The company benefits from extensive partnerships and a robust infrastructure. The lack of explicit contact and compliance information on this page suggests that this is a specialized resource rather than a primary corporate site.

Security posture

The website demonstrates a good security posture with HTTPS enabled and use of crossorigin attributes to enhance resource security. However, the absence of security headers such as Content-Security-Policy and lack of published security policies or incident response contacts limit transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. The integration of multiple analytics and tracking pixels indicates extensive user tracking, which should be balanced with privacy compliance measures. Overall, security practices are sound but could be enhanced by publishing formal policies and improving header configurations.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement and display a cookie consent mechanism to comply with privacy regulations.
  3. Add explicit security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information for security incidents and incident response procedures.
  5. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern tech stack centered on React 17.0.2 and custom Yandex libraries, hosted on Yandex's own infrastructure. Performance is optimized with preloading of fonts and scripts, and mobile optimization is good. Accessibility features such as focus-visible outlines and responsive design are present. SEO is supported by comprehensive meta tags and Open Graph data. No CMS is detected, indicating a custom-built platform. The site integrates multiple analytics services, reflecting a mature data collection strategy. Technical risks are minimal but could be reduced by enhancing security headers and privacy compliance.
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.
