There are two possible methods to accomplish the redirection of traffic to Cisco WSA: transparent proxy mode and explicit proxy mode.

In a transparent proxy deployment, a WCCP v2-capable network device redirects all TCP traffic with a destination of port 80 or 443 to Cisco WSA, without any configuration on the client. The transparent proxy deployment is used in this design, and the Cisco ASA firewall is used to redirect traffic to the appliance because all of the outbound web traffic passes through the device and is generally managed by the same operations staff who manage Cisco WSA.

Cisco Hybrid Email Security is a unique service offering that facilitates the deployment of your email security infrastructure both on premises and in the cloud. You can change the number of on-premises versus cloud users at any time throughout the term of your contract, assuming the total number of users does not change.

This allows for deployment flexibility as your organization's needs change.

Cisco Email Security Appliance (ESA) protects the email infrastructure and employees who use email at work by filtering unsolicited and malicious email before it reaches the user. Cisco ESA easily integrates into existing email infrastructures with a high degree of flexibility. It does this by acting as a Mail Transfer Agent (MTA) within the email-delivery chain. Another name for an MTA is a mail relay.
