Tejas Jain - PeerSpot reviewer
Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
Mahendra Basera - PeerSpot reviewer

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.
