If you rely on SaaS or cloud-based delivery
models for business-critical applications, there is a compelling
need for per-application policy enforcement without increasing remote
office infrastructure. Traditional hardware-based approaches are
limited by heavy-handed all-or-nothing policies for direct-to-internet versus
policy enforcement per-application. Additionally, because router-based approaches
are packet-based versus application-session-based, they fail to
meet application session-symmetry requirements, causing network
and security outages.
