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.

Secures east-west cloud traffic and improves threat visibility through deep inspection
SonicWall NSv offers great features. I cannot pinpoint a single best feature, but the best feature is the ability to deliver the full, high-efficiency inspection power of a physical SonicWall, including zero-day defense using Real-Time Deep Memory Inspection to the cloud, efficiently removing the performance versus cloud trade-off typically associated with virtual firewalls. Regarding deep memory inspection and real-time zero-day defense in SonicWall NSv, deep memory inspection is distinct from traditional sandboxing methods because it is focused on what is happening in the memory during file execution time, rather than just observing file system behavior. The deep memory inspection process addresses all challenges by employing a proprietary technique within the secure analysis environment, focusing on CPU-level analysis and real-time verdict. Those are the key points. SonicWall NSv's user interface is quite clear and easy to navigate. If someone has not worked with SonicWall and this is their first experience with the platform, I would highly recommend it. It is very easy to navigate and very user-friendly. SonicWall NSv has positively impacted our organization because we gained clear visibility into our network, and it helps to identify potential security issues that we had. We were able to remediate those issues, and so far, we have had a great experience with SonicWall NSv. We were able to manage approximately 99% of network-based attacks through this platform.
