Introduction

SonicWALL NSA 250M is a powerful network security appliance of SonicWALL module series that can be the best security solutions for branch offices and/or distributed enterprises. Features such as application control, intrusion prevention, content filtering, etc. allow security administrators to make this appliance almost foolproof network protection entity, and that too without decreasing the efficiency and performance of the network infrastructure. Moreover, if wireless model of the appliance is opted, SonicWALL NSA 250M allows the devices of both 5 GHz and 2.4 GHz bandwidth to communicate with the network, using the deployed appliance as a wireless access point for the Infrastructure wireless topology.

Who Should Buy?

SonicWALL NSA 250M security appliance is best suited for:

• Branch Offices – Branch offices of any large enterprise can use SonicWALL NSA 250M to secure their networks from internal and external threats. Using this security appliance, such branch offices can also create up to 50 site-to-site VPN tunnels to allow accessibility to the resources in internal network from remote locations.
• Distributed Enterprises – SonicWALL NSA 250M can be used in distributed enterprises to create SSL VPN tunnels for encrypted remote accessing.

What Purposes It Serves?

SonicWALL NSA 250M is useful for the branch offices or distributed enterprises that want to provide remote access to their internal networks using SSL VPN tunnels. Organizations that want to allow IEEE 802.11a/b/g/n wireless devices to communicate with the network internally or through SSL VPN connections can also use this security appliance.
Moreover, organizations that plan to extend their networks in future can use this SonicWALL NSA 250M module series security appliance and can add additional modules to the device for better scalability.

Top Features and Benefits

Some top features and benefits of SonicWALL NSA 250M are:

• Application Control – SonicWALL NSA 250M can be used to throttle down or completely block any unwanted bandwidth intensive application. This prevents wastage of bandwidth and also protects the network from facing network congestions.
• Distributed Network Protection – SonicWALL NSA 250M security appliance can be configured for intrusion prevention and content filtering at branch offices of distributed enterprises.
• WAN Acceleration – SonicWALL NSA 250M can be used to prevent users from opening inappropriate web sites when integrated with SonicWALL's WAN Acceleration Appliance (WXA).
• Gateway Protection – SonicWALL NSA 250M is capable of protecting the internal network by preventing intrusions and blocking spywares, malwares and other potentially harmful scripts right at the gateway.
• Module Integration – SonicWALL NSA 250M security appliance can be exploited best when used with branch offices or distributed enterprises that plan to extend/modify their networks in future. Different SonicWALL modules can be integrated with the appliance to best fit the organizations' needs. Some modules that can be integrated with SonicWALL NSA 250M are:
• 4-Port GbE Module
• 2-Port SFP Module
• T1/E1 Module
• ADSL Annex A Module
• ADSL Annex B Module
• LAN Bypass GbE Module
• High Performance – Because of Reassembly-Free Deep Packet Inspection engine, SonicWALL NSA 250M security appliance can inspect several connections on all the ports at the same time and that too without introducing latency to the network. 5 GbE ports can deep-inspect the packets at 130 Mbps, hence securing the network without letting the users experience reduced network performance.
• Deep Packet Inspection SSL – SonicWALL NSA 250M can deep-inspect SSL packets. The process includes decrypting an SSL packet, inspecting it and re-encrypting it before allowing or denying it to enter into the network.
• Stateful Hardware Failover – SonicWALL NSA 250M also allows security administrators to configure stateful hardware failover in order to provide uninterrupted network connectivity among all users in the entire setup. With the help of stateful hardware failover, users that connect to the network using SSL VPN can experience uninterrupted remote access to the network even in the cases of active SonicWALL NSA 250M hardware failure.
• Centrally Managed Policies – With the help of Global Management System (GMS), SonicWALL NSA 250M allows administrators to create and manage security policies that can be implemented on the appliance to protect the internal network. The policies can be created and managed from a central location, hence allowing the administrators to manage them right from their desks.
• Enforced Protection – SonicWALL NSA 250M also ensures that all the connected nodes have Kaspersky or McAfee antivirus applications installed on them and are updated with the latest virus definitions.
