I was wondering if it would be acceptable to ask you a few questions about your experience with Juniper solutions. I would be interested to know your relationship with Juniper, whether you are a customer, end user, reseller, implementer, partner, or MSP. The reviewer rated Juniper Contrail SD-WAN 11 out of 10.

Session-based routing has transformed branch failover and now optimizes application paths
Juniper Session Smart Router is a very good cloud integration router, with very strong application visibility, and WAN path optimization is also present. It has very good simplified branch connectivity, particularly strong automation and API support, and better SaaS performance. Session-based routing instead of tunnel-heavy architecture is one of the best features. Session-based routing and API support in Juniper Session Smart Router have helped me in my work. It helps in session-based routing changes from route-based packets only on destination IP to application session awareness. This can help with a better application experience, and voice or video traffic automatically takes the best WAN path based on latency, jitter, and packet loss. Faster failover occurs; instead of waiting for routing protocol convergence, sessions can dynamically move to healthier links. Additionally, there is improved SaaS performance. In terms of APIs, I have had a very good experience integrating it with automation platforms like Terraform and Ansible. It has reduced manual errors, and my team has been using the API to automate deployment and dozens of other tasks with branch SSR devices. Another feature I can think of regarding Juniper Session Smart Router is that there is no traditional overlay tunnel overhead in many scenarios, which is one of the best features. Dynamic path selection based on latency and jitter makes this one of the standout features.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"My customers use the solution to have better control and knowledge about the applications inside ONE Access. It also helps them cut costs by reducing MPLs and using better internet access from FTTH."
"It gives you that level of visibility to understand what's going on between layer four and layer seven."
"Juniper has layer four to seven protection; it gives you that level of visibility to understand what's going on between layer four and layer seven and helps us reduce bandwidth compared to competitors' MPLS circuits while providing a strong platform for cloud migration to AWS and GCP without any sort of extra bandwidth from the MPLS circuits."
"The solution is more specific about what's happening since it explains where the problem may lie and points out areas where there is a problem. So, we like that it provides more visibility."
"JUNIPER CDWAN ROI is excellent as product has long life cycle and therefore supported with no need to buy replacement products."
"I've worked with several SD-WAN solutions over the past few years, and the product felt more like an automated provisioning tool. Unlike solutions from Palo Alto or other SD-WANs orchestrated by a SaaS solution, Juniper Contrail SD-WAN already had the files and built their SaaS to orchestrate the configuration. Initially, you didn't do much, but then it started adding some routing capabilities."
"I would appreciate your thoughts about the security capabilities of Juniper Contrail SD-WAN, particularly its built-in features."
"The support is very good from Juniper and from the local distributors."
"The biggest advantage of Juniper Session Smart Router that really stands out is its reliability and performance."
"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."
"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."
"They provided us with a customized product according to our requirements."
"Customer service is very prompt."
"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."
"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."
"I can share specific numbers; we achieved a 30 to 60% WAN cost reduction by reducing MPLS usage."
 

Cons

"The training could be better. When it comes to the demo dashboard capability, I feel like it could be much easier for our customers to use. Our last customer complained about this."
"Implementing new branches or changing existing ones in Juniper Contrail SD-WAN wasn't as straightforward as with other solutions like Meraki SD-WAN, which is almost plug-and-play with its zero-touch provisioning. In Juniper Contrail SD-WAN, it was more challenging."
"The only issue was the switch we got, which was a little problematic because it was PoC equipment, and we had a little problem with that."
"The solution is expensive. Its support can be better."
"The solution installs similarly to competitors. It is not more difficult or easier. However, it could be easier and take less time for the installation."
"Areas for improvement in the Juniper Contrail SD-WAN solution include the on-premises deployment process."
"I found some weaknesses on their hardware. They are sometimes breaking very often."
"Juniper Session Smart Router could be better in terms of software performance."
"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 can be improved by simplifying onboarding for traditional network teams and providing better documentation for complex deployments, as well as improving the GUI for operational workflows and better migration tooling."
"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."
"Regarding improvement, we still need to see what it can do."
"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."
"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."
 

Pricing and Cost Advice

"They are neither very expensive nor cheap. So, we can consider its pricing somewhere in the middle."
"The cost of the solution is a little expensive. The hardware is a one-time purchase fee and the software is purchased on an annual basis. There are additional costs for other software features that are available which are on an annual basis, such as extra capacity."
"The licensing structure is very flexible."
"It is a simple bandwidth-based license and the orchestration comes bundled with the solution by default."
"We are currently renegotiating the offer for the licenses and the license bundle model. The license for an ISP has to be different from the license for an end customer. This is something we are currently renegotiating with Juniper, but, of course, the pricing for the licensing is always an issue when you want to get more customers."
