L1 engineers cannot work on the Palo Alto Networks K2-Series because it's too complex, which requires L2 and above level of engineers.
Director at MICROLOGIC NETWORKS PRIVATE LIMITED
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.

This would help end-user customers understand the impact when those firmwares are pushed into the live environment.
Head of IT and Information Security at GLEEDS USA INC
The issues I have experienced are not hardware-related but firmware-related, as Gen 7 has new hardware, while the firmware contains some issues that could be resolved but may take considerable time.

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.

Head of IT and Information Security at GLEEDS USA INC
Support has resolved concerns promptly and security tools have strengthened intrusion prevention and access control
The service we received from SonicWall NSSP and their distributors has been excellent. Every time I have had a concern, they have resolved it in a single call. The interface of SonicWall NSSP console is user-friendly with comprehensive features. The web filtering and access control policy are top priorities for me. It is very effective because it prevents any indecent behaviors in the network or from outside the network. Half of the task is completed by the intelligence based on the behavior. Installation was easy because our infrastructure has minimal requirements. For expanded infrastructure, support from a SonicWall NSSP technical team may be required. We have implemented it on our own.
