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

AO Kaspersky Lab is a globally recognized leader in cybersecurity solutions, offering premium protection products for both households and businesses. Founded in 1997 by Eugene Kaspersky, the company has grown into one of the largest private cybersecurity firms worldwide. Their Czech website targets local consumers and enterprises with a comprehensive portfolio including antivirus software, VPN services, password management, and parental controls. The brand is well-positioned in the market, supported by numerous independent awards and certifications, reflecting strong trust and credibility. Technically, the website leverages modern frameworks such as React and Next.js, ensuring fast performance, mobile responsiveness, and good accessibility. The use of advanced analytics and consent management tools demonstrates digital maturity and compliance with privacy regulations. Security best practices are evident through HTTPS enforcement and robust security headers, although the absence of publicly available WHOIS data slightly detracts from transparency. The security posture is strong, with no visible vulnerabilities or exposed sensitive data. However, the lack of a public incident response policy or dedicated security contact channels suggests room for improvement in transparency and readiness. Overall, the site presents a professional, trustworthy front with comprehensive content and user-friendly navigation. Strategically, AO Kaspersky Lab should focus on enhancing WHOIS transparency, publishing detailed security policies, and maintaining rigorous third-party script audits to uphold its market leadership and trustworthiness.

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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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 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

Kaspersky operates in the technology sector, specializing in cybersecurity software and services. Their business model revolves around direct sales of security products and subscriptions to consumers and enterprises. The company enjoys a strong market position as a global leader, supported by a broad product range and extensive partner ecosystem. Revenue streams likely include software licenses, renewals, and value-added services such as VPN and password management. The target audience spans individual users, families, small businesses, and large enterprises. Growth indicators include continuous product innovation, international localization, and active community engagement. Partnerships with distributors and resellers further strengthen market reach. The company maintains a consistent brand image and invests in marketing and certifications to sustain competitive advantage.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no detected vulnerabilities in the visible content. Privacy compliance is supported by a detailed privacy policy and cookie consent mechanisms. However, the absence of a public security policy, incident response plan, or security.txt file limits transparency and may impact stakeholder confidence. No dedicated security contact emails (e.g., security@ or abuse@) were found, which is a best practice for vulnerability reporting. The use of third-party analytics and marketing scripts is managed with consent, reducing privacy risks. Overall, the security maturity is high but could be improved by publishing formal security governance documents and enhancing incident response visibility.

Recommendations

  1. Publish a publicly accessible security policy and incident response plan to improve transparency.
  2. Implement and publish a security.txt file to facilitate vulnerability disclosure.
  3. Add dedicated security contact channels (e.g., security@kaspersky.cz) for incident reporting.
  4. Regularly audit and minimize third-party scripts to reduce potential attack surface.
  5. Update WHOIS registration data to enhance domain transparency and trust.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, enabling server-side rendering and fast client-side interactivity. It uses CSS modules for styling and integrates third-party services such as Cookiebot for consent management, Yandex Metrika and Google Tag Manager for analytics, and Kameleoon for marketing optimization. The site is well-optimized for mobile devices and accessibility, with semantic HTML and ARIA attributes. Performance is fast with preloading of critical assets and font optimizations. No CMS was explicitly detected, suggesting a custom or headless approach. Hosting provider details are not disclosed. The technical implementation reflects a high level of digital maturity and adherence to best practices, though continuous monitoring for third-party script risks is advised.
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.
