Review summaries and opinions

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

ROI

Sentiment score
6.0
Cisco Catalyst SD-WAN reduces costs, downtime, MPLS reliance, and ensures swift financial returns, enhancing flexibility and deployment speed.
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 Inniti Network Solutions
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.
Information Technology Consultant at Island Networks
There are many scenarios where we replace MPLS with the internet because now we have the flexibility to migrate to Cisco Catalyst SD-WAN and we do not need private connectivity such as MPLS.
Regional Manager at Orange
 

Customer Service

Sentiment score
7.4
Cisco Catalyst SD-WAN support is responsive and effective, though some users cite delays and prefer handling troubleshooting themselves.
Sentiment score
6.1
Citrix's NetScaler support is generally helpful but inconsistent, with issues like delays, expertise gaps, and slow complex problem resolution.
The principal third-level support is very good.
Technology supervisor at a non-profit with 1-10 employees
I would consider Cisco support a 10 out of 10.
Information Technology Consultant at Island Networks
I would rate Cisco's support, their customer service, and technical support as excellent.
Solution Architect at Sonda S.A.
 

Scalability Issues

Sentiment score
7.2
Cisco Catalyst SD-WAN is scalable and adaptable, ideal for large-scale enterprise deployments with flexible configurations and robust architecture.
Sentiment score
7.8
NetScaler is praised for scalability and flexibility, though licensing complexity and multi-tenancy limitations pose challenges for some users.
Its controller architecture is highly matured, making it one of the most valuable and reliable LAN platforms for large enterprises.
Network engineer at Inniti Network Solutions
Cisco SD-WAN is highly scalable and can be expanded to more than 10,000 sites.
Technical Consultant at Vertex Techno Solutions (B) Pvt Ltd
The ease of configuration and features like zero-touch provisioning enhance the scalability of Cisco SD-WAN, especially in disaster recovery situations.
Engineer at Routz
 

Stability Issues

Sentiment score
7.5
Cisco Catalyst SD-WAN is reliable with good performance, but some users face software bugs and complexities after acquisition.
Sentiment score
7.6
NetScaler is highly stable and reliable, with minor configuration issues not significantly affecting its overall functionality.
For example, with zero-touch provisioning, if we are adding new sites, we can do it with a few simple clicks.
Regional Manager at Orange
While some software-related issues and bugs were encountered, they did not cause the whole environment to crash.
Engineer at Routz
A simple issue in the control connections between the fabric causes numerous complexities.
Network Manager at HPCL
 

Room For Improvement

Cisco Catalyst SD-WAN needs improved flexibility, user interface, cloud integration, and support, plus enhanced analytics, AI, and scalability.
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 Inniti Network Solutions
Including more features like integrating with Splunk for monitoring vulnerabilities would help eliminate the need for other SOC solutions.
Technical Consultant at Vertex Techno Solutions (B) Pvt Ltd
 

Setup Cost

Cisco Catalyst SD-WAN is considered expensive, with complex licensing and additional costs, despite discounts and robust features.
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.
