2 Why today s Firewalls are broken Visibility No visibility into user behavior No control over applications Manageability No centralized management No centralized deployment Intelligence No network optimization No traffic prioritization Security No Network Access Control No IDS/IPS No Secure Remote Access

3 Regaining Control is Essential Control Application Usage Cloud enablement & WAN virtualization Operations cost control Access Control & Mobility

4 Introducing the Barracuda NG Firewall Powerful network firewall Full application control Full user awareness Intelligent traffic management Comprehensive IDS/IPS Centrally manage all functionality

5 The Evolution of the Firewall WAN optimization Centralized management Scalability Remote network access Reporting/Audit capabilities Quality of Service (QoS) Application control Identity awareness Ports, packets, protocols Anti-virus scanning Barracuda NG Firewall Next Generation Firewall Traditional Firewall/UTM

6 Challenges: Port-Based Firewalls Loss of network control Application driven malware Block UDP traffic Block FTP traffic Allow HTTP Mimic Web Browsing HTTP Live Streaming Port Hopping

7 Regain Control Application Awareness Block unwanted applications Control and throttle acceptable traffic Preserve bandwidth and speed-up business critical applications Intercept SSL encrypted application traffic Business Critical? Acceptable? Security Flaw?

8 Traditional Use Case Block Traffic Block unwanted applications for certain users or groups

9 Get Smarter Selective Blocking Block unwanted applications for certain users or groups Enable or disable application specific sub-functions (e.g. Facebook Mail)

10 Improving Overall Network Quality Control and throttle acceptable traffic

11 Protect and Support the Business Control and throttle acceptable traffic Preserve bandwidth and speed up business-critical applications
