  • The alternative we propose is with Zscaler’s Direct to Cloud Network. If you can imagine the advantages of directing all of your internet and cloud bound traffic through a globally deployed Cloud infrastructure without having to manage all of the costly hardware and software – it offers compelling flexibility, economics and simplicity without compromising any of the security capabilities and requirements.In fact, in our security “deep dive” presentation we can share how Zscaler actually provides better security to address advanced threats given the volume of transactions we scan across our Cloud Network each day.So all of a sudden you have an infrastructure available anywhere in the world, that can manage your employee internet and cloud activities with uniform policies… available instantly – and do this regardless of what device employees may be using to access the cloud and internet
  • In a more simplistic picture – the best way to think of Zscaler, is as a global check-post sitting between your employees and the Cloud. In a more technical term some of you might view Zscaler as a Massively scalable and fast Proxy available anytime, globally from any device.
  • We have talked much about the global nature of the Zscaler Direct to Cloud Network. It is worth while to share the extent to which we have deployed infrastructure to offer you comparable access – and in many cases better access – than you would receive using your current method of accessing the Cloud and Internet.
  • I’ll take a moment to explain how Zscaler works – we think you will see the simplicity in what we do and how you can quickly deploy on the Zscaler Direct to Cloud Network.Your administrator sets up policy and launches it on our cloud through a simple but comprehensive web interface – these policies are made available instantly across our global networkCloud and Internet bound traffic is forwarded from your employees using a number of techniques – which we can discuss more in our technical discussionAll employee web and email traffic goes through our global cloud network where policy is applied – traffic that is allowed goes through to its destination - - - traffic that is denied will return a notice to the userOnce the cloud and internet is accessed – the Zscaler network scans all traffic for threats and Advanced threats and protects your business network from malicious intentAt any time – your admin or C-level executives have access to instant reporting that can be customized for summary or detailed investigation or review

  • 4. Agenda ‣ Why Security Socket Layer (SSL) Encryption ‣ SSL Challenges & Trends ‣ Upgrading 1024 to 2048-bit SSL: The Mandate ‣ Upgrade Implications For Appliance Based Security ‣ How Zscaler Secures Enterprises ‣ Benefits of Direct to Cloud ‣Q & A
  • 5. What is SSL? • Widely used on the Internet for authenticating sites and providing encrypted traffic exchange 5
  • 6. SSL Traffic is Exploding SSL on Internet Search Social Networking Webmail Enterprise Banking Login Transactions All App Coverage ‣ Internet is moving to default SSL (Google, Facebook, etc.) ‣ SSL puts lots of load on systems and security infrastructure
  • 7. Enterprise Attacks Shifting from Servers to Users Direct server attacks: Rare Servers: stationary, consolidated behind FWs ‣ Mobility and cloud make users vulnerable – any place, any device, direct to net ‣ Malware can be delivered over SSL ‣ Botnets call home over SSL ‣ Enterprise visibility and control is missing Users: the Beachhead Used to attack servers Are your USERS SECURE EVERYWHERE?
  • 8. ▶ All existing 1024-bit certificates must be replaced with 2048bit SSL certificates by December 31, 2013 ▶ Better Security ▶ Performance Upgrading 1024 to 2048-bit SSL: The Mandate 1024 bit 5X Performance Degradation 80% Performance Drop 2048 bit Security
  • 9. Can Your Security Appliance Handle This? ‣ How do you deal with mobile users and many distributed office locations? ‣ Are your cloud applications like Office365, Box, Google Apps, etc. bottlenecked? ‣ Are you scanning SSL traffic? – If NOT, you have a BIG security/visibility GAP ‣ Do you use appliance based proxy servers? ‣ Can your appliance handle SSL interception with 2048-bit? 9
