Juniper Session Smart Router has positively impacted my organization by simplifying SD-WAN deployments, allowing us to operate with fewer staff, as its integration with Juniper Mist AI takes on much of the workload, thereby offering reliable performance and stability without software issues.

Juniper Session Smart Router has positively impacted my organization by achieving a 30% to 40% reduction in WAN cost, which means less reliance on MPLS, with a 40% faster failover with near-zero user impact during link issues, and 20% to 30% less time spent on troubleshooting, along with fewer outages due to dynamic path selection, which facilitates fast branch deployment.

For telecom companies, I think zero-trust segmentation is the way to go because if you allow anything that you do not understand, then it becomes a problem.

The best feature is the easiest way to deploy configuration and also back up them, and also to roll back quickly if there's an incident.

As compared to the other major vendors in the SD-WAN market, such as VeloCloud, Cisco, and others, the tunnel-free and secure vector routing technology is its major USP, which gives plenty of room to discuss with the customer why IPSec from 1998 is a bit outdated.

One area for improvement that I have observed is related to the VPN, where I frequently notice VPN flaps or disconnections between Juniper Session Smart Router and the SD-WAN hub device in the data center, which should be addressed to prevent users from experiencing any downtime.

A key area for improvement in Juniper Session Smart Router is its security stack, which is not as robust as Fortinet.

Juniper Session Smart Router could be better in several areas such as the steep learning curve because the session-based model is different from traditional networking.

Juniper Session Smart Router could improve its documentation to become more competitive. It has very little documentation, and you have to rely mainly so much on support to do something, which I feel should not be that way.

The UI of the SSR conductor is the main part where improvements can be done. Today, for every configuration step, you have to do a series of clicks. What we are missing there are wizards. For example, I have two applications, and I want one application to be prioritized against the other. In such a case, a wizard for assigning policies to a service without configuring each step by hand would be very helpful. There should be an overhaul of the GUI of the conductor. The functionality they have got in the Mist portal should be baked into the conductor itself. It would be really great, but as we all know, that won't happen.

Juniper Session Smart Router can improve the integration for Wi-Fi devices and add additional Sassy deployments.
