Regex Tester & Validator

This regular expression matches specific Kaspersky endpoint domains used for downloading updates, including numbered 'upd' servers (e.g., s00.upd.kaspersky.com), 'downloads.upd.kaspersky.com', and 'cm.k.kaspersky-labs.com'. It is typically utilized in firewall rules, proxy configurations, or TLS inspection policies to accurately identify and route traffic destined for Kaspersky's legitimate security update servers.
