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

ROI

Sentiment score
5.3
Cisco Catalyst SD-WAN offers ROI benefits through cost savings, efficiency, reduced latency, and enhanced management despite initial costs.
Sentiment score
8.1
NetScaler improves security, stability, and cost-efficiency, enhancing operations and supporting medium enterprises with effective load balancing.
With Zero Trust provisioning via the Catalyst Center and Meraki dashboard, new branch offices are configured in hours instead of weeks, freeing engineering teams to focus on strategic initiatives rather than manual deployment.
Network engineer at a tech services company with 11-50 employees
I can deploy to remote areas now with Starlink and SD-WAN, which I was previously unable to do.
Azure Architect at a mining and metals company with 5,001-10,000 employees
They are now back to do that with the remainder of their company, so they've realized the value in 12 months and are willing to invest in the remainder of their organization.

Customer Service

Sentiment score
7.3
Cisco Catalyst SD-WAN's support is praised for responsiveness and competence but needs improvement in initial response and complex issue handling.

Regional Manager at Orange
Cisco Catalyst SD-WAN is indeed stable in my environment.
SAP IT Projects Lead at a manufacturing company with 5,001-10,000 employees

Room For Improvement

Cisco Catalyst SD-WAN benefits from enhanced flexibility, detailed analytics, security features, and improved ease of use and deployment.
NetScaler needs improved documentation, user experience, support, integration, scalability, security, and licensing to enhance user satisfaction and efficiency.
Now, they change frequently, making it difficult to obtain long-term support.
Technology supervisor at a non-profit with 1-10 employees
Better documentation with real-world examples, improved third-party integration, and more detailed monitoring dashboards would make Cisco Catalyst SD-WAN even more effective.
Network engineer at a tech services company with 11-50 employees
The UI can be improved, the licensing experience can be improved, and the dashboard can be more useful since it is somewhat cluttered.
Senior Network Engineer at a tech vendor with 5,001-10,000 employees
 

Setup Cost

Cisco Catalyst SD-WAN is costly and complex, but some enterprises find its comprehensive capabilities worth the investment.
NetScaler is robust but considered expensive, with high subscription fees and pricing often above competitors like A10.
Its pricing is justifiable due to the comprehensive solution it offers.
Technical Consultant at Vertex Techno Solutions (B) Pvt Ltd
It is also relatively cost-effective for smaller businesses when using the Meraki version.
Engineer at Routz
The pricing of Cisco Catalyst SD-WAN is rated between eight and nine out of ten, where ten is the most expensive.
Technology supervisor at a non-profit with 1-10 employees

Regional Manager at Orange
Centralized control has simplified cloud access and has improved operational visibility
If they can have better firewall features as their competitors have, such as Fortinet and Versa, that would help to place this solution better so that we can address security related things. If they can have all the IPS, IDS, everything built on all the edge devices, whether physical or virtual, that could be one improvement. Actually, if customers are existing Cisco customers, if Cisco can be more flexible to leverage the existing investment, that could be another important aspect to save on cost and be more competitive from a pricing perspective. Overall, the pricing or the segment that Cisco deals with is a bit premium, which they charge a bit premium against the competition on the licensing, hardware, and services. The implementation is not straightforward. You need a specialized partner or specialized people who can implement this. It can be simplified a bit from that perspective as well. Mostly the way we implement the policies for a big environment requires a lot of things that we need to take care of. If that can somehow be improved, because they have different components, like they have vManage, they have vSmart, and vBond and all these components have to work with a certain flow that they need to follow.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.
