Has automation features but provisioning new branches or making changes to the existing ones is difficult
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. The automation features do help with network operations. Manually configuring SD-WAN is complicated, so the automation simplifies that. However, the initial SD-WAN solution had many limitations, particularly regarding its features. At some point, the tool began looking for other solutions and bought the 128T, which led to implementing a different SD-WAN approach. It also acquired another company for its session smart router, and then it began to develop the exact SD-WAN solution on the Mist Cloud.

Secure healthcare connectivity has protected patient data and supports reliable telemedicine
Everything can be improved. It could improve its security stack with malware detection, particularly in healthcare because of ransomware. Now you have IoT vulnerabilities, so something like advanced malware detection or threat analysis would help. This is something I worked with around 2016 to 2017. Perhaps they have added those features, but I know they didn't have it then. Some security profiles for specific medical devices would be helpful. Sandboxing would be good. Dedicated telemedicine routing profiles would be beneficial because we have a lot of telemedicine going on. Real-time sessions for clinicians may need pre-built templates for EHR and EMR. I think those would be good if they're not already there. I don't know what the latest router has, but I know they didn't have those features then. There can always be improvements because technology is constantly advancing. It is a very solid router, and that is one of many industries that could utilize it. Healthcare is one such industry, and if it works for healthcare, then that is a major plus for that router.

Quotes from Members

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

Pros

"JUNIPER CDWAN ROI is excellent as product has long life cycle and therefore supported with no need to buy replacement products."
"It supports desktop management, network management, and SD-WAN policies."
"The support is very good from Juniper and from the local distributors."
"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 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."
"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."
"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."
"Overall, it is very solid."
"The solution is especially Session's smart, application-aware, AI-based."
"I can share specific numbers; we achieved a 30 to 60% WAN cost reduction by reducing MPLS usage."
"The real-time analytics and visibility features are excellent, and its special troubleshooting tool is very strong."
"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."
"They provided us with a customized product according to our requirements."
"Juniper Session Smart Router's real-time analytics and visibility features are easily accessible."
 

Cons

"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."
"The solution is expensive. Its support can be better."
"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."
"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."
"Areas for improvement in the Juniper Contrail SD-WAN solution include the on-premises deployment process."
"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."
"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 should have a more user-friendly graphical interface because the user interface is complex, and some upgrade operations are sometimes difficult."
"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."
"Regarding improvement, we still need to see what it can do."
"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."
"I found some weaknesses on their hardware. They are sometimes breaking very often."
"My overall rating for Juniper Session Smart Router as a product is that earlier it was good, but currently, the replacement of the devices is very difficult, and the staff is also a challenge."
"Juniper Session Smart Router could be better in terms of software performance."
 

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."
