  • Updating databases and application software modules.
  • Verifying access to Kaspersky servers. If access to the servers using system DNS is not possible, the application uses public DNS. This is necessary to make sure anti-virus databases are updated and the level of security is maintained for the computer. Kaspersky VPN Secure Connection uses the following list of public DNS servers in the following order:
    1. Google Public DNS (8.8.8.8).
    2. Cloudflare DNS (1.1.1.1).
    3. Alibaba Cloud DNS (223.6.6.6).
    4. Quad9 DNS (9.9.9.9).
    5. CleanBrowsing (185.228.168.168).

Requests sent by the application may contain addresses of domains and the public IP address of the user because the application establishes a TCP/UDP connection with the DNS server. This information is needed, for example, to validate the certificate of a web resource when using HTTPS. If Kaspersky VPN Secure Connection is using a public DNS server, data processing is governed by the privacy policy of the relevant service. If you want to prevent Kaspersky VPN Secure Connection from using a public DNS server, contact Customer Service for a private patch.
