Which Cisco Umbrella package supports selective proxy for inspection of traffic from risky domains?

Cisco Umbrella's DNS Security Advantage package includes the intelligent proxy, which selectively proxies HTTP/S requests for domains determined to be risky, allowing for deeper content inspection and threat analysis beyond just DNS blocking.

SIG Essentials is a broader Secure Internet Gateway package that includes the intelligent proxy feature, but DNS Security Advantage is the specific package where this feature is introduced as part of advanced DNS security.

DNS Security Essentials is a basic package focused on DNS-layer security and does not include the intelligent proxy for selective traffic inspection.

SIG Advantage is the most comprehensive SIG package, including all features of SIG Essentials plus advanced threat intelligence and other advanced security services, but it is not the minimum package providing selective proxy specific to risky domains.
