It's best suited for small offices 10-25 users. Any more and its best to move away to a more higher tier. It will be less appropriate for a mid level company with a large staff. It's best for a small business with a limited budget and less strenuous security functionality.
As an edge/WAN router that contains internet BGP routes, it handles this work very well. And the devices are robust, able to manage a significant load. However, the interface cost can be somewhat of a hindrance when wanting to use it to interconnect many metro clients.
I would like to able to find more examples of configs. Given the multiple ways to configure the same setting, having a little more documentation would be helpful.
The features are good. The support is good. The resources to deploy, manage, and operate it are good. Customer's feedback and testimonials are good. The updates in terms of zero day vulnerabilities are good and timely. But, I still give an 8 out of 10 because I think the pricing, licensing, and GUI can be improved more.
Juniper support is friendly, easy to understand, widely knowledgeable, and easy to get ahold of. I did not give them a higher rating as some of my more complex issues, were solved by myself while under consultation from Juniper TAC.
Cisco's power really stems from its brand reputation and honestly not much else. No one ever got fired for deploying Cisco, and that's why it stands out. The Cisco Small Business RV Series is no exception there; the unit is built well and does the job. However, much more powerful alternatives for routers are out there—the biggest competitor being Ubiquiti. The UniFi routers are significantly more powerful in all regards, including routing speed, IPS/IDS speeds, and VPN functionality. Support for those is admittedly rather lackluster though, so if your network is critical, you are effectively self-insuring your equipment. For some that may be fine, but for others, that risk of extended downtime is just not worth it.
The simplicity, elegance, and robustness of Juniper's solution make it much easier to troubleshoot and configure, when compared to Cisco Routers, especially considering Cisco's implementation of BGP (why are IPv4 and IPv6 linked in Cisco configuration?). Furthermore, the implementation of commit and rollback cannot be understated when compared to the Cisco solutions. This feature is a huge time saver when attempting to troubleshoot and remote configuration instances.
The stability and robustness of this solution provide a rock-solid foundation for all of our internet traffic.
The easy to use rollback and commit features simplifies remote administration and configuration, alleviating the need to travel to remote installation sites.
