ASM vs Palo Alto Firewall
From time to time we see customer confusion between two kinds of application firewalls, a Web Application Firewall and an application firewall like PaloAlto Networks.
I just saw that PaloAlto published a Whitepaper that describes the differences between a WAF and their Application Firewall. This Whitepaper summarizes the differences in a pretty accurate way (aside from their comment on WAF performance which isn't accurate for F5's platforms)
