We use it to upload, delete, and list what to publish on the net to block websites and even posts.
Recently, I blocked Adobe Acrobat Reader. When you install it on your PC, sometimes it contacts the internet and opens some posts. Thus, it can be easily hacked by a user on the internet. When you browse for this kind of list, you can easily upload it on Palo Alto without any difficulty.
It's very easy to use and configure.
What is nice about Palo Alto is that even if you don't understand how to use it, you can just click on upload and upload everything that needs to be blocked.
It also has signature-based prevention.
The interface is really user friendly. You can easily see what sites you have been blocking and their criticality.
You can also capture packets from this tool, which is really nice.
The cost involves the price of the hardware, which is expensive. However, most of the Palo Alto solutions are expensive.
These devices cost a lot here in Mauritius, for example, one device can cost approximately $4,000. The cost for the license would be in addition to this.
I would rate this solution at ten on a scale from one to ten because I've never had any issues with it and have never been hacked.
