Numerous support challenges arise but unique security features impress
In this scenario with Palo Alto Networks Advanced Threat Prevention, I did not get any opportunity to work on it. The only thing I did was forward the logs to the SIEM ( /categories/security-information-and-event-management-siem ) solution.For government entities, they are not allowing configuration changes. For non-government users, there is a support portal to get the configuration file and upload it to the portal. We can identify misconfigurations and where the loop is very big, so we can get the report and establish it. In Saudi Arabia specifically, the support service needs improvement. When customers have incidents with Palo Alto Networks Advanced Threat Prevention and want to open a case with the Palo Alto team, the available number in Saudi Arabia leads to a long procedure. They're not able to answer within one or two hours. This needs to be implemented. They may need to open offices in Dubai or other places for Arabic-speaking people to access TAC support.

It allows for a separation between cloud applications and URL filtering
We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve.

"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
 

Cons

"Mission learning techniques should continue to expand and detect unknown threats on the fly."
"The solution needs to improve its local technical support services. There is no premium support offered in our market."

"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."

"The pricing has improved with the newer generation of their Firewalls, but the price could always be lower."
"It's not too expensive."
