Cisco Umbrella
Cisco Umbrella's cloud-delivered security enables an immediate improvement in security and compliance posture. That's because DNS is at the heart of every internet connection request. Securing the DNS layer means blocking malicious domains, IP addresses, and cloud applications before a connection is ever established.
