Security score

79/100

Risk levelLow

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

Yandex is a leading technology company specializing in intelligent products and services powered by machine learning, with a strong market position primarily in Russia and expanding globally. Their offerings include a fast internet search engine, on-demand transportation services, navigation products, and various mobile applications. The company has a long history since 1997 and is publicly listed on NASDAQ, indicating a mature and established business. Technically, the website employs modern JavaScript technologies, performance monitoring, and error tracking, reflecting a high level of digital maturity. Security posture is generally good with HTTPS enforced and domain transfer protections, but lacks visible security headers and published security policies. Privacy compliance is weak due to absence of explicit privacy and cookie policies on the main page. Overall, the website is professional, trustworthy, and well-branded, but could improve transparency and security disclosures to enhance user 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

4 findings rated critical or high. Fix these first.

  1. 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

  2. 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 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

Yandex operates in the technology and transportation sectors, leveraging machine learning to deliver localized search and information services. Their business model includes advertising revenue from search, fees from transportation services, and monetization of navigation and mobile apps. The company targets a broad audience including consumers and businesses. Their competitive advantage lies in local market expertise, extensive service portfolio, and technological innovation. The presence of 17 offices worldwide and NASDAQ listing signals strong growth and global ambitions. Partnerships and integrations with other Yandex services likely enhance ecosystem stickiness. The company maintains a consistent brand image and high content quality, supporting strong market credibility.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enabled and domain transfer restrictions in place. Use of advanced client-side monitoring scripts indicates proactive performance and error management. However, the absence of DNSSEC, security headers, and publicly available security or incident response policies represents gaps. No vulnerability disclosure program or security.txt file was found, limiting transparency for security researchers. No exposed sensitive data or known vulnerabilities were detected in the analyzed content. Overall, the security maturity is good but could be enhanced by adopting additional best practices and publishing security governance information.

Recommendations

  1. Enable DNSSEC on the domain to protect against DNS spoofing and improve DNS security.
  2. Publish comprehensive privacy and cookie policies clearly accessible from the homepage.
  3. Implement and disclose a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  5. Provide public documentation of security policies and incident response procedures to improve transparency and trust.

Technical notes

Notes

The website uses a modern JavaScript stack with React framework indications and advanced browser APIs for performance and user interaction monitoring. Hosting is stable with a reputable registrar and domain age supports long-term operation. The site is optimized for desktop and mobile platforms with responsive design and accessibility considerations. Performance is fast with efficient resource loading and caching strategies. Technical debt appears low with up-to-date libraries and no deprecated technologies detected. Opportunities exist to improve security headers and privacy compliance disclosures to reduce technical risks and enhance user 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.
