The Dell SonicWALL TZ Series is the most secure Unified Threat Management (UTM) firewall for small businesses, retail deployments, remote sites, branch offices and distributed enterprises. Unlike consumer-grade products, the TZ Series delivers the most effective anti-malware, intrusion prevention, content/URL filtering and application control capabilities along with the broadest most secure mobile platform support for laptops, smartphones and tablets. It provides full deep packet inspection (DPI) at very high performance levels, eliminating the network bottleneck that other products introduce, and enabling organizations to realize increased productivity gains. The TZ Series is the most secure, sophisticated and widely-deployed security platform on the market today.

Small businesses, retail deployments, government organizations, remote sites and branch offices can benefit from the powerful security and business-class performance of the new Dell SonicWALL TZ 205. Unlike consumer grade products, this powerful Unified Threat Management (UTM) firewall combines the most effective intrusion prevention, anti-malware and content/URL filtering with the broadest, most secure mobile platform support for laptops, smartphones and tablets. By providing full deep packet inspection (DPI) at very high performance levels, it eliminates the tradeoff between comprehensive security and performance.


Intrusion Prevention (Requires the Gateway Anti-Malware, Intrusion Prevention and Application Control Service)


Signature-based scanning:  Tightly integrated, signature-based intrusion prevention scans packet payloads for vulnerabilities and exploits that target critical internal systems.

Automatic signature updates:  Dell SonicWALL's Research Team continuously updates and deploys an extensive list of over 5,400 IPS signatures covering 52 attack categories. These signatures take immediate effect and do not require reboots or any other interruption in service.

Outbound threat prevention:  The ability to inspect both inbound and outbound traffic ensures that the network will not unwittingly be used in Distributed Denial of Service attacks and will prevent any Command and Control Botnet communication.

Intra-zone IPS protection:  Intrusion prevention can be deployed between internal security zones to protect sensitive servers and to prevent internal attacks.




IPSec VPN for site-to-site connectivity:  High-performance IPSec VPN allows the firewall to connect remote branch offices to a central location.

SSL VPN or IPSec client remote access:  Utilize clientless SSL VPN technology or an easy-to-manage IPSec client for easy access to email, files, computers, intranet sites and applications from a variety of platforms.

Redundant VPN gateway:  When using multiple WANs, a primary and secondary VPN can be configured to allow seamless automatic failover and failback of all VPN sessions.

Route-based VPN:  The ability to perform dynamic routing over VPN links ensures continuous uptime in the event of a temporary VPN tunnel failure by seamlessly re-routing traffic between endpoints through alternate routes.

Clean VPN:  Dell SonicWALL Clean VPN™ both secures the integrity of VPN access and decontaminates malicious threats before they can enter the corporate network.


Gateway threat prevention (Requires the Gateway Anti-Malware, Intrusion Prevention and Application Control Service)


Gateway anti-malware:  Dell SonicWALL's patented RFDPI engine scans all ports and protocols for viruses without file size or stream length limitation. SonicLabs Researchers constantly provide updated threat protection, providing faster response times and threat prevention.

Reassembly-Free Deep Packet (RFDPI):  Reassembly-Free Deep Packet Inspection keeps track of malware regardless of the order or inspection timing with which the packets arrive. This allows for extremely low latency while eliminating file and stream size limitations. This provides greater performance and security than outdated proxy designs which reassemble contents using sockets bolted to traditional anti-virus programs and are plagued with inefficiencies and the overhead of memory thrashing leading to high latency, low performance and size limitations.

Cloud anti-virus:  Using the built-in RFDI engine, Dell SonicWALL can leverage the power of the cloud to provide the most comprehensive set of anti-malware signatures available, while minimizing latency or delay. The Dell SonicWALL Cloud Anti-Virus Service provides millions of additional malware signatures for inspection of executable files using the most up-to-date information available.

Bi-directional Inspection: RFDPI can be performed on both inbound and outbound connections to provide protection in all network traffic directions.

24x7 signature updates:  SonicLabs Research Team creates and updates signature databases that are propagated automatically to the firewalls in the field, with those signatures taking immediate effect without any reboot or service interruption required.


Firewall and Networking


Stateful packet inspection:  All network traffic is inspected, analyzed and brought into compliance with firewall access policies.

DOS attack protection:  SYN Flood protection provides defense against DOS attacks using both layer 3 SYN proxy and layer 2 SYN blacklisting technologies.

Flexible deployment:  Can be deployed in traditional NAT and Layer 2 Bridge modes.

Policy-based routing:  Create routes based on protocol to direct traffic to a preferred WAN connection with the ability to fail back to a secondary WAN in the event of an outage.

High availability:  Supports Active/Passive failover to ensure increased reliability by protecting against hardware or software faults.

WAN load balancing:  Load balance up to four WAN interfaces using Round Robin, Spillover or Percentage based methods.

WAN acceleration:  WAN Acceleration decreases latency and increases transfer speeds between remote sites for even higher network efficiency gains.




Advanced QoS: Guarantee critical communications with 802.1p and DSCP tagging and remapping of VoIP traffic on the network.

DPI of VoIP traffic: Predefined signatures detect and block VoIP specific threats.

H.323 gatekeeper and SIP proxy support: Block spam calls by requiring that all incoming calls are authorized and authenticated by H.323 gatekeeper or SIP proxy.


Management and Monitoring


Web GUI:  An intuitive web-based interface allows quick and convenient configuration in addition to management through Dell SonicWALL Global Management System (GMS), or the CLI.

SNMPSNMP:  SNMP provides the ability to protectively monitor and respond to threats and alerts.

Centralized policy management:  With Dell SonicWALL GMS, monitor, configure and report on multiple Dell SonicWALL appliances from a single intuitive interface and customize your security environment to suit your individual policies.


Application Intelligence and Control (Requires the Gateway Anti-Malware, Intrusion Prevention and Application Control Service)


Application control:  Identify and control applications or individual components of an application based on RFDPI technology instead of relying on well-known ports and protocols.

Application bandwidth management:  Allocate bandwidth to critical applications while throttling unproductive application traffic for an efficient and productive network.

Custom application identification:  Create and configure custom application identification based on traffic parameters or on patterns unique to an application in its network communications.

Application signature database:  A continuously expanding database of over 3,500 application signatures ensures that administrators are able to control the usage of all the latest applications on their network at a category or individual level.

User activity tracking:  User identification is seamlessly integrated with Microsoft Active Directory and other authentication systems enabling tracking and reporting of individual user identification.

1 out of 5 eggsNot again

Pros: I guess it worked as a firewall for the year and a half until the unit started failing. (Lost packets, inability to handle data, SUPER slow throughput when one outside VPN active.)

Cons: We installed a TZ 205 to act as a firewall over two small LANs and to allow one VPN user to each network. (Two small businesses sharing building space, separate networks behind a shared firewall.)

Because my VPN expertise is limited, we hired a SONICWall certified tech to complete the install. The unit never worked properly for the second VPN user and now, after a year and a half, it is failing. Over a thousand bucks into purchasing and installing this little unit, buying the second license and the subscription (crazy expensive) and now its dying. Might as well have just burned the cash.

I will never again buy a Sonicwall product.

4 out of 5 eggsOK....but

Pros: Small, Compact, seems to work well. Install wizard works good. I have owned previous sonic walls, so the configuration was not a mystery.

Cons: Claims to be 12000 connections, Only 10000. Subtract 1 egg for misrepresentation.

Other Thoughts: Dell customer service sucks. When trying to contact them to point out the error in the specification, the only reply was that your support agreement is expired. This is on the 6th day of owning the device.

2 out of 5 eggsGreat reputation but poor quality

Pros: Good color - very clean looking and the unit is shipped in a gorgeous cardboard box. The plastic wrap surrounding the unit seemed to be high quality and very transparent. The adhesive tape securing the package appeared to be applied straight and with nary a wrinkle.

Cons: This unit was selected as a more high-throughput option to the 7 year-old Linksys RV082 router. Sadly, this router is a far cry slower that the old Linksys. In actual speed tests the SonicWall is faster than the Linksys, but the time required to load web pages, S/R email, or download a file is much slower with the SonicWall TZ-205. And if you'd like to talk to someone for support or maybe allow an experienced tech to look at configuration in a remote session, it ain't happening.

Other Thoughts: I had great success with other SonicWall routers and security appliances, but this one has found a home on the DNU (do not use) lit. It's a great router, it just doesn't do the job it was intended to.

5 out of 5 eggsOne of the easiest firewall i ever configured

Pros: Wizard is awesome, simple and right to the point . For those who plan to use it an don't know how buy support 8x5 for around $100 a year. I am sure after a year you going to feel comfortable with it.

Cons: For some reason sonicwall in general is not friendly with VoIP and needs tailoring.

Other Thoughts: Its great for small business applications.

5 out of 5 eggsGreat Firewall

Pros: These are great units. I have installed many of them and have 20+ years as a tech. They can be a bit complicated to figure out but that is because it is very configurable and has a lot of options.

Cons: None.

Other Thoughts: Please ignore the 1 star review. If you can't figure out how to sign into it then it will be over your head on how to configure it. :)

1 out of 5 eggsTotal rip-off

Pros: The box looks nice. (I was not able to use it so I don't know how it works.)

Cons: This unit comes with no support. And without support you cannot log in to the firewall. So you can't configure & use it.

I think it's really sleazy that they sell you this box, then tell you that you need to pay more to use it.

5 out of 5 eggspowerful but complex

Pros: Purchased this to get a step up in security for our small business office (10 users) for a reasonable price. The hardware is handling the traffic of our office without any noticeable drop off in speed and we have full stateful packet inspection turned on including all the security features.

The interface is slick, well laid out and responsive. You can do very complex things that are normally only available in much higher end firewalls.

Cons: The price you pay is only for the basics. Expect to pay about $330/yr more if you want all the services they offer with this unit. I didn't deduct an egg for this because this was pretty obvious to me when I bought the router and paying annually for dynamic security services ensures that there are people at those places maintaining it at a high level.

I wish this device had sonicwall's new geosecurity feature where you can block entire country IP blocks. It wasn't clear to me from their website that this model didnt have it. If you want that, you have to move up to the tz 215 (which sucks, they need to bring that feature to the 205).

Other Thoughts: No way to sugarcoat this, IT'S COMPLICATED. It has the interface of a much more powerful router and unless you are a network engineer or have experience in this field, this will be very difficult to wrap your head around and configure. They offer a few wizards to help you along the way but even the wizards require some level of knowledge and are inefficient in adding way more rules than are needed. Again, I didn't deduct an egg for this because sonicwall gives you a test interface to see (so you know what you are getting into) on their website and the documentation is very good / complete. However, let me repeat, don't buy this unless you have the expertise to use it or plan to spend a significant amount of time learning lots of complex network topics. Things that are simple with lesser routers like NAT port translation require MANY more steps.

We don't use the VPN feature at all (so far) so I can't give any notes on how well that worked.

5 out of 5 eggsGreat Home firewall

Pros: This is the perfect SOHO firwirewall for anyone with a cable or dsl connection. I installed mine and had it fully operational with 7 computers and a cable connection in less than an hour. The instructions are simply, yet the firewall options are plentiful. I needed this for my home network because wireshark had told me there were people secretly controling my personal files and folders on my personal pc.

Cons: Learning how to use all of the features.

Other Thoughts: This is a powerful little firewall that I would DEFINITELY recommend to anyone with a home network. I an thinking of buying another one for my brother's home network.
