Cisco Umbrella uses real time intelligence to prevent access to malicious websites through Domain Name System (DNS) filtering. Security categories such as Malware, Phishing, Crypto mining, etc. can be leveraged alongside content-based categories. Cisco Umbrella is useful for applying filtering to segmented networks, such as a BYOD network, applying a base ruleset to all traffic on that segment. Built into the licensing is the 24/7 MDR service from Aspire, which works well with other MDR services.
