The Network Security SonicOS Platform Secure Network Optimization

For many organizations, the identity and composition of application traffic is a puzzle. This is problematic in that the rapid evolution of the Web has changed the office forever with broad adoption of Web 2.0 and social networking applications which have created an entirely new set of IT requirements for securing, controlling and ensuring bandwidth in the new enterprise network. IT often tries to improve Wide Area Network (WAN) network performance by expending budget on more bandwidth or enhanced services. Unfortunately, these efforts frequently fall short of expectations.

Employee usage of time-wasting and often dangerous applications creates more challenges for IT as more bandwidth is used on non-critical business applications. Critical business applications need bandwidth prioritization, while social media and gaming applications need to be bandwidth throttled or completely blocked.

Additionally, applications such as Microsoft® SharePoint and Windows® File Share (WFS) transmit an increasing number of files and data sets, while at the same time inefficiently retransmitting entire files (rather than just incremental changes) multiple times, unnecessarily increasing traffic passed over the WAN.

At the same time, organizations need to protect themselves against constantly evolving intrusion and malware attacks by conducting deep packet inspection (DPI) of all network traffic in real time, without introducing latency.

WAN acceleration technology can help resolve part of the problem by providing more efficient utilization of the existing WAN bandwidth. However, without inline application intelligence and control, and without full DPI protection, typical WAN acceleration solutions may have limited effectiveness at controlling and securing all aspects of application traffic. Worse, they can even accelerate threats across the network.

Without insight into the network and application traffic, IT can’t effectively secure and control the network and stay ahead of today’s constantly evolving threats, application-related challenges, and bandwidth issues.

Dell SonicWALL Secure Network Optimization.

The Dell®SonicWALL® Secure Network Optimization solution tightly integrates Dell SonicWALL Next-Generation Firewall Application Intelligence and Control, Deep Packet Inspection scanning, and Application Traffic Analytics with the WAN Acceleration Appliance (WXA) Series, enabling organizations to:

Analyze application traffic.

Dell SonicWALL Next-Generation Firewall plus Application Traffic Analytics arms IT with real-time and historical insight from Syslog, IPFIX and NetFlow data. The Next-Generation Firewall provides real-time visualization of ongoing application traffic, providing invaluable insight to what’s currently happening on the network. Application Traffic Analytics augments this with historical data so IT now has in-depth insight into how employees utilize resources and how applications impact the network on a daily, weekly, monthly or even yearly basis.

Block undesirable applications.

Application bandwidth management identifies and blocks counterproductive and potentially dangerous application traffic such as social media, peer-to-peer (P2P), instant messaging and rogue applications.

Bandwidth manage applications.

Application bandwidth management identifies and controls counter-productive traffic such as social media, P2P, instant messaging and rogue applications, and forwards only policy-appropriate productivity enabling traffic such as and video conferencing applications for acceleration.

Reduce traffic between sites.

Application-intelligent optimization ensures the firewall forwards only that traffic needing to be accelerated between distributed corporate sites. Data de-duplication via byte and file caching reduces bandwidth consumption by orders of magnitude, extending the life of existing WAN links and providing a better user experience. In addition, WFS acceleration helps improve response times while decreasing the amount of data transferred when downloading or accessing files from a shared drive. Protocol optimization provides LAN-like application performance for users accessing resources over the WAN by decreasing the latency and chattiness presented by inefficient protocols or application communication. Moreover, data compression across the WAN increases performance and reduces latency.

Enhance security.

Dell SonicWALL Reassembly-Free Deep Packet Inspection™ scans all traffic for threats and vulnerabilities, enhancing security by detecting and preventing malware and intrusions before data is accelerated across the WAN.

Identify network inefficiencies.

Real-time traffic visualization delivers strategic insight into the performance gains obtained by the WAN Acceleration solutions, while continuing to identify undesirable or unsafe applications.

Simplify management.

Providing a consolidated management interface helps ease the cost of deployment and lowers total cost of ownership by minimizing infrastructure, training and administrative overhead. Plus, automated application signature updates simplify administration by ensuring the network is protected against the latest threats.

Increase productivity.

By controlling and optimizing WAN bandwidth, the combined Dell SonicWALL solution of Application Intelligence and Control and WAN Acceleration makes it significantly faster and easier for employees to access, process and share critical information over the WAN, which correspondingly increases staff productivity.

Enjoy a unique synergistic approach.

Dell SonicWALL Secure Network Optimization enables IT to transition to an advanced security platform that can stay ahead of today’s constantly evolving landscape of threats and application-related issues. The platform uniquely consolidates core Next-Generation Firewall application intelligence, control and visualization, gateway protection, application traffic analytics and inspection for SSL encrypted sessions for enterprises with a critical WAN acceleration solution for distributed offices, elements that work seamlessly and dynamically together to maximize security and control with minimum network latency.
