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 focusing on cybersecurity solutions. Its business model revolves around software sales and subscription services for home users and businesses. The company leverages a broad partnership ecosystem and maintains a global footprint with localized websites. Revenue streams likely include direct sales, renewals, and enterprise contracts. The website's content and structure indicate a focus on customer trust, transparency, and product excellence. Growth indicators include continuous product updates, awards, and active customer engagement through social media and community platforms.

Security posture

The website demonstrates a high level of security maturity with enforced HTTPS, comprehensive security headers, and no exposed sensitive information. However, explicit security policies and incident response details are not publicly available, which could be improved. There is no visible vulnerability disclosure program or security.txt file, which are recommended best practices. Overall, the security posture is strong but could benefit from enhanced transparency and formalized disclosure mechanisms.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency.
  2. Implement and publicize a vulnerability disclosure program and security.txt file.
  3. Provide contact details for a Data Protection Officer to improve GDPR compliance visibility.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Enhance user education on security features and privacy practices via the website.

Technical notes

Notes

The website uses a modern React and Next.js tech stack, ensuring good performance and SEO optimization. It integrates advanced personalization and analytics tools like Kameleoon and Google Tag Manager. The site is mobile-optimized and accessible, with a clean and professional design. Hosting details are not explicit but likely use a CDN or cloud provider for global reach. No technical debt or outdated libraries were detected. Opportunities exist to improve technical transparency around security and privacy implementations.
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.
