Solutions Architect at Navarino SA
The ease of installation and licensing are also significant advantages
We use the application filtering, content filtering, and intrusion prevention system (IPS) features. These features are crucial for our network security. The ease of installation and licensing are also significant advantages, as it allows us to have one license for all products, which simplifies upgrading and maintenance. Additionally, the ease of deployment is critical for us.

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.
