Mahendra Basera - PeerSpot reviewer
Sr. Engineer at InterGlobe Technology Quotient
Automated breach prevention has protected critical workloads and keeps external attacks blocked
I am familiar with SonicWall TZ. I have done a POC of TZ but I have not worked extensively with it. I have worked with the 2600 firewall and then the 3600. These are the models which we have worked with.SonicWall NSa was an on-premises solution. The two firewalls which were in production, in the data center and on the LAN side, were both on-premises solutions. We had a pre-decided budget under which we would purchase the firewall. All parameters including security, high availability, and budget concerns were covered with SonicWall NSa being implemented at that time. SonicWall NSa is a user-friendly product that is easy to configure, and it is easy for network personnel and firewall administrators to work with. Even the L1 team captured and learned this firewall effectively, helping us resolve all parameters related to high availability firewalls within budget-friendly costs. I rate this review a nine out of ten.

Advanced security filters have blocked threats and protect our users’ web and application access
SonicWall TZ gives us multiple features, such as Content Filter, Application Filter, ATP, IPS policy, Geo-Filter, Botnet filter, and many more. I use Content Filter with SonicWall TZ most of the time because we need to create a policy on behalf of the content filter to track who is using what. If we want to block any types of websites for any specific user, we can do it from the firewall. SonicWall TZ has multiple features, such as Application Filter as well. SonicWall TZ has impacted our organization positively because it stops all threats. If any types of malware signature or any types of bad behavior malware appear, it prevents them.

Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB. The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand. I have read that an approximate number of users in the highest TZ series (TZ 670)...

Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB.  The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand.  I have read that an approximate number of users in the highest TZ series (TZ 670) is around 150 to 200 but that is just an estimate.  Hope this helps. You can get more details in SonicWall datasheets where you will find the speed, throughput and more technical specifications to select the one that fits your requirements.

In simple words, TZ is for small businesses (less than 100, maximum 150 users).  TZ has fewer ports. NSA is for medium and large enterprises: > 150 Users,  NSA has many ports to support large networks
