Abstract: A secure web gateway for a cloud computing environment comprises a data plane component, comprising: a front-end domain name service (DNS) configured to receive an inbound DNS request and map an IP address of the DNS request to a policy identification value corresponding to a customer policy and a plurality of plugin modules utilized by the front-end DNS to process the DNS request according to the mapping of the IP address from which the DNS request originates to the policy identification value. The secure web gateway further comprises a control plane component that provides the customer policy to the front-end DNS and configures the IP address to permit access to a DNS service according to the customer policy.
