1. Blue Coat Enables IPv6 Ehab Derbas Territory Sales Manager, ME May 2009

2. Agenda • What is IPv6 • Customer challenges • Considerations • Evaluation criteria • Blue Coat solutions • Summary

3. What is IPv6 • New Internet Protocol born in 1993 • Increases address space by 4x • Simplifies headers • Replaces IPv4, but can also co-exist • Core network infrastructure has been upgraded

4. Customer Challenges • Elimination of NAT firewall • Broader risk surface area • Greater risk to internal network (from outside) • New (NAT-challenged) apps/services available • Extending security policy • Maintaining visibility

5. Network Design Considerations • Compliance & backhaul requirements • Asymmetric routing VRRP Internet HSRP ISP1 ISP2 Internet intranet

6. The Right Solution • Provides evolution from IPv4 • Mature, customer-proven solution • Technical understanding of IPv6 • Focus on application requirements • Balance of performance & control

7. Blue Coat Expertise • Began IPv6 program in 2004 • Shipped first alpha release in 2005 • Operated beta program on native IPv6 backbone • Active participation in IETF & IPv6 Forum • Patented IPv6 proxy technologies • Beta available now; GA release planned for 2H CY09

8. Power of Blue Coat ProxySG • Fills NAT gap • Broad protocol support • Full visibility including SSL • Rich, per-user policy • Application prioritization • Acceleration & bandwidth optimization • ProxySG is leader • Market leader in Secure Web Gateway & WAN optimization • Used by 97 of global F100 & the world’s top ten telcos

9. Transition to IPv6 • ProxySG deployed today for IPv4 eases transition • Extend policies to IPv6 • IPv4-only apps/services with IPv6-only users & vice-versa • Full connection termination • No need for translation • Mask internal network architecture • Enforce IPv6 end-to-end communication model
