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.

Strong threat prevention has reduced phishing and malware while I monitor traffic in depth
Palo Alto Networks NG Firewalls offers application and user awareness, which allow me to control traffic based on threats. The product includes threat prevention, advanced threat prevention, and deep packet inspection that really helps prevent issues in our network. Deep packet inspection inspects full traffic content, even inside applications and encrypted sessions. Deep packet inspection makes a very practical difference day to day because it lets me see and control what is actually inside the traffic, not just the open port or IP. I have real visibility of which application is running instead of just seeing HTTPS. Palo Alto Networks NG Firewalls WildFire sandboxing is really good at detecting and blocking zero-day malware automatically, along with its GlobalProtect and DNS security features. Using Palo Alto Networks NG Firewalls positively impacts my organization by providing strong security, better visibility, faster response, and simplified operations. After deploying Palo Alto Networks NG Firewalls in our network, it blocks malicious traffic and prevents compromises that occurred before Palo Alto Networks NG Firewalls. I can now block outside IPs to prevent issues. After Palo Alto Networks NG Firewalls installation, I reduced 60 to 70 percent of malware and phishing attacks. Its threat prevention and DNS security features detect these attacks, block malicious domains, and reduce manual efforts for the security team.
