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

6 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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  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.

Technical appendix

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

Business context

Business profile

VK operates as an enterprise-scale social network with a diversified service portfolio targeting general audiences. Its business model revolves around advertising, digital content, and platform services. The company benefits from a long-established domain and consistent branding. Integration with partners like Mail.ru enhances its marketing and analytics capabilities. The platform's extensive use of mini apps and video content indicates a strategy focused on user engagement and monetization through multiple channels. VK's market position as the largest European social network underscores its competitive advantage and broad user base.

Security posture

VK exhibits a strong security posture with mandatory HTTPS, domain transfer restrictions, and active error monitoring via Sentry. However, the absence of a publicly accessible security policy, vulnerability disclosure program, or incident response contacts suggests areas for improvement in transparency and user trust. No critical vulnerabilities or exposed sensitive data were detected in the analyzed content. The site uses modern security best practices but could enhance compliance by publishing explicit security and incident response documentation.

Recommendations

  1. Enable DNSSEC to improve domain security and prevent DNS spoofing.
  2. Publish a dedicated security policy page outlining security practices and user guidance.
  3. Implement and publicize a vulnerability disclosure program or security.txt file.
  4. Provide clear incident response contact channels such as security@ or abuse@ emails.
  5. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website employs a modern and robust technical stack including React, MobX, and VKUI, ensuring a responsive and performant user experience. The use of ES modules and advanced browser APIs like PerformanceObserver indicates a focus on performance monitoring and optimization. Hosting is managed by a reputable Russian registrar with a long domain history. The site is well-optimized for mobile devices and accessibility, with comprehensive CSS and font management. No CMS was detected, suggesting a custom-built platform tailored to VK's specific needs. Overall, the technical infrastructure supports scalability and rich interactive 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.
