Cisco ScanSafe, aka Cisco Cloud Web Security

Hi, I'm doing some research on the Cisco Cloud Web Security offering, also known as ScanSafe. Has anyone on the lists explored Cisco's ScanSafe SaaS offering, now called Cisco Cloud Web Security - as a means of providing protection in the cloud that would potentially negate the requirement to have a full tunnel (i.e. allow split tunneling) for teleworkers? Thanks!
