Application Evolution “Application” has evolved to include web browser, web server, application server, operating system Delivery can be on-premise or hosted in the cloud, or some combination Regardless of delivery model, most data now browser-based Well known port numbers Port 80 (HTTP) / Port 443 (HTTPS)

Beyond Application Identification Today’s Network Security Requires Application Detection, Monitoring, and Control Allowing access to Web 2.0 applications has made enforcing data security policies far more complex User-created content embeds threats in content, pages, links, comments to blogs… Protection against effects of social media applications Data loss Threat propagation Bandwidth consumption Inappropriate use Endpoint to the Core “Single pane of glass” management for visibility & control

Identification Over 1,500 applications More added every week Category IM, P2P, Remote Access, Video, etc. Ranked on popularity & risk Impendent of port, protocol, IP address Decrypt encrypted traffic Including HTTPS, POP3S, SMTPS and IMAPS protocols

Summary Comprehensive High Performance Real Time FortiOS Operating System FortiASIC Network Processor FortiGuard Threat Research FIREWALL IPS VPN ANTIVIRUS/ ANTISPYWARE WEB FILTERING Fortinet built and owns all 3 key components— Integrated security technologies, High speed processors Global update and support services Our FortiOS operating system enables us to efficiently deliver consolidated security without compromise. We can add additional technologies without suffering a performance breakdown. Our FortiASICs add significant processing advantage over a other approaches delivering accelerated performance Our FortiGuard and FortiCare infrastructure delivers product updates and customer support around the world Some of our competitors, whether they are NGFW or UTM, cannot deliver the complete solution: Security vendors offer a broad set of features, but do a poor job of integrating them and pay a performance penalty Networking vendors may deliver better performance, but their security technology does not have the compressive range of technologies, and doesn’t provide complete content protection There are many who claim leadership in the market, but Fortinet had delivered for 10 years.
