SOHO Series is an entry-level firewall that extends the kind of advanced threat protection that enterprises enjoy. It is packaged with a SMB-friendly price tag. Ideal for home offices, small offices, SMBs, distributed enterprises such as restaurant & retail chains.


Why Choose SonicWall Firewall SOHO 250?

SonicWall SOHO 250 TZ series enables small to mid-size organizations and distributed enterprises. Combining high-speed threat prevention and software-defined wide area networking (SD-WAN) technology with a wide range of networking and wireless features plus simplified deployment and centralized management, the TZ series provides a unified security solution at a low total cost of ownership.

Distributed retail businesses and campus environments can take advantage of the many tools in SonicOS to gain even greater benefits. Branch locations are able to exchange information securely with the central office using virtual private networking (VPN). Creating virtual LANs (VLANs) enables segmentation of the network into separate corporate and customer groups with rules that determine the level of communication with devices on other VLANs. SD-WAN offers a secure alternative to costly MPLS circuits while delivering consistent application performance and availability. Deploying TZ firewalls to remote locations is easy using Zero-Touch Deployment which enables provisioning of the firewall remotely through the cloud.

Key Features

RFDI Engine.

This high-performance, proprietary and patented inspection engine performs stream-based, bi-directional traffic analysis, without proxying or buffering, to uncover intrusion attempts and malware and to identify application traffic regardless of port.

Secure SD-WAN.

An alternative to more expensive technologies such as MPLS, Secure SD-WAN enables distributed enterprise organizations to build, operate and manage secure, high-performance networks across remote sites for the purpose of sharing data, applications and services using readily-available, low-cost public internet services.

Cloud-based and on-premises management.

Configuration and management of SonicWall appliances is available via the cloud through the SonicWall Capture Security Center and on-premises using SonicWall Global Management System (GMS).

Virtual Private Networking

Simplifies and reduces complex distributed firewall deployment down to a trivial effort by automating the initial site-to-site VPN gateway provisioning between SonicWall firewalls while security and connectivity occurs instantly and automatically.

Content/context awareness.

Identifies and controls network traffic going to or coming from specific countries to either protect against attacks from known or suspected origins of threat activity, or to investigate suspicious traffic originating from the network. Provides the ability to create custom country and Botnet lists to override an incorrect country or Botnet tag associated with an IP address. Eliminates unwanted filtering of IP addresses due to misclassification.

Capture Advanced Threat Protection.

The multi-engine sandbox platform, which includes virtualized sandboxing, full system emulation, and hypervisor level analysis technology, executes suspicious code and analyze behavior, providing comprehensive visibility to malicious activity.

Encrypted Threat Prevention.

Decrypts and inspects TLS/SSL encrypted traffic on the fly, without proxying, for malware, intrusions and data leakage, and applies application, URL and content control policies in order to protect against threats hidden in encrypted traffic. Included with security subscriptions for all TZ series models except SOHO. Sold as a separate license on SOHO.

Application intelligence and control.

Control applications, or individual application features, that are identified by the RFDPI engine against a continuously expanding database of over thousands of application signatures, to increase network security and enhance network productivity.

Content Filtering.

Block content using the predefined categories or any combination of categories. Filtering can be scheduled by time of day, such as during school or business hours, and applied to individual users or groups.

Enforce Anti-Virus and Anti-Spyware.

Powerful spyware protection scans and blocks the installation of a comprehensive array of spyware programs on desktops and laptops before they transmit confidential data, providing greater desktop security and performance.
