60% of IT Professionals Cite Performance as Key Challenge for Cloud

No Probes• Deep packet inspection

• Passive monitoring for voice, video, critical apps and best-effort apps

• No additional hardware (and included in IOS-AX license)

Business-Aligned Privacy Enforcement• No need for complex IP and port

ACLs

• See inside HTTP flows to identify specific Cloud applications

Smart Capacity Planning• Better use of expensive bandwidth

• Per-branch and per-application level reporting
