Associate Director IT Operations at Procento
Single-pane management has simplified firewall control and has improved risk mitigation
I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

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.
