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.
