- 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 Endpoint Security uses the following list of public DNS servers in the following order:
- Google Public DNS (8.8.8.8).
- Cloudflare DNS (1.1.1.1).
- Alibaba Cloud DNS (223.6.6.6).
- Quad9 DNS (9.9.9.9).
- CleanBrowsing (185.228.168.168).
Requests emitted 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 Endpoint Security is using a public DNS server, data processing is governed by the privacy policy of the relevant service. If you want to prevent Kaspersky Endpoint Security from using a public DNS server, contact Technical Support for a private patch.
