Security policies in combination with zones: It is very easy to organize the security polices in a logical structure.

vSRX is easy to deploy to any virtual infrastructure, such as OpenStack, VMware, and even Docker (cSRX).

Juniper has the "recovery safety feature", so if you perform a "commit confirmed" and the new configuration disconnects you. then there is no "confirmed" command with X mins (default = 10 mins). It automatically reverts (recovers) to the previous configuration. This is handy for when you do not want to make that trip down range just to reboot a router.

The web interface on Juniper SRX is just a short conversion from Junos OS CLI; this is not very suitable for users with little expertise/

It would be good if Junos had "unique commands" between all hierarchical levels, discarding the use of the "Run" command.

The visibility/reporting could be better. To see something, you have to export the log to a syslog and then process with another product.

It could improve areas which need high performance.

Third-party support for Juniper is a lot less than Cisco. This is no surprise, but a definite consideration if you are expecting to use a lot of third party support. In my guesstimate, for every 100 Cisco shops, you will find one Juniper shop.

I would like them to add a dashboard because it's difficult to operate.

Juniper needs to focus more on their perimeter firewalls.

It did not improve our safety because the IDS does not detect some attacks, but our anti-virus software did.

This solution needs to update for "Next Generation" needs.
