Palo Alto Networks PA-Series is basically integrated with LDAP to fetch the identity of the users and we provide access based on the identity.

Integrated threat intelligence has empowered my organization to adapt to threats by taking a lot of the burden off us; there's just no way we would see the same breadth of knowledge that a vendor or manufacturer would have.

When I compare the tool with other firewalls, it’s the most powerful. It's the most powerful security engine. All the traffic going to the Internet passes through it as the first layer of protection. Because of its good performance, we also use it for decryption.

A valuable feature that we can consider is the deployment time, which is significantly reduced, almost 90% faster compared to other solutions. This leads to quicker deployment and less downtime.

It has its own logging system. You can go to monitoring and check the logs to see if a connection is getting blocked. You can use multiple types of logs to check if a file or a port is getting blocked or if there are any TCP resets from the source or destination. It's easy to troubleshoot with the monitoring and logging it provides.

It is scalable. But that depends on what model you are using.

Licenses are too costly. As I compare with Check Point or other OEM, the licenses are too much more costly and they should work on bundled licenses.

Because they have a separate license for VPNs and do not provide any type of quick support, which is why I have rated it nine instead of a perfect score.

However, they are expensive and there might be some sticker shock if you just looked at them for the price.

There are no AI integrations in the Palo Alto Networks PA-Series firewall. I would like to see something in the future, but as of now, it is not required.

I had opened a case before with the tool because I could not create a wildcard for the security address. We can create wildcards for security addresses in Fortinet, but this feature doesn't exist in the product.

I have found that the tool works well for me, but there are areas where security testing and protection could be improved, especially in virtual or cloud environments. However, in this project, once we deployed it, we haven't encountered any issues. The cost is currently manageable, but as we migrate fully into the cloud, additional features like capacity upgrading and improvements to hardware resources will be necessary, especially since our equipment consists of older generation switches and routers. So, I'm looking for additional capabilities in these areas.

There seem to be some issues with TAC (Technical Assistance Center) or Palo Alto support. Anytime you open a case, a level one engineer joins, and then you have to escalate it to level two or three. The support system has changed in the past few years, and that's something they need to look into.

There are constant updates for the operating system. It is a nice thing also, but it has its own disadvantages. Continuous updates are there. The users face issues like, how often do I need to update that? Within a period of five months, I'm updating it two or three times. It gives them a feeling that they are not confident about their product and have to update it so frequently.
