The scalability of Cisco ACI supports our organization's growth effectively.

Expanding your network or your data center with Cisco ACI is not an issue; scalability is a good feature.

Cisco ACI is highly stable and reliable, with most users rating its performance between eight and ten.
Sentiment score
8.2
Meraki SD-WAN is reliable, consistently performing well with minimal disruptions and high stability ratings, praised for its user-friendly interface.
For stability, Cisco ACI rates a nine or 9.5 because I've seen three customers using Cisco ACI and once deployed, the solution is very stable.
Network Technical Manager at KPMG
Cisco ACI is stable in my experience.
Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees
Sometimes it is not working in Azure or GCP as it has interoperability only with some clouds, so that part needs work.
Solution Architect at airtel
 

Room For Improvement

Cisco ACI struggles with complexity, user-friendliness, cloud integration, security, cost, and support, hindering customer adoption and satisfaction.
Meraki SD-WAN requires improved security, cost-effectiveness, WAN optimization, cloud integration, customization, VPN capabilities, scalability, and user interface.
What we need is something called RAG, or retrieval-augmented generation. If Cisco can implement that to utilize customer-specific data instead of general knowledge, while ensuring data privacy under GDPR laws, I think that will result in very good, reliable output.

Their lack of on-ground offices can result in business losses.
Chief Technology Officer at Mehbub General Trading PLC
We do not make use of its visibility and analytics features, as we are mostly using it for the networking part only.
S VP, IT Infra at ATOM
VeloCloud provides much more detail and many more tabs for troubleshooting everything, such as ARP, IPv4, IPv6, TCP dumps, routing, and switching.
NOC Technical Lead at a tech services company with 10,001+ employees
I work with Fortinet where with a single command you can deploy the entire SD-WAN along with FortiGuard within minutes.
Solution Architect at airtel
Cisco is one of the top vendors with the most stable performance in many solutions, but it all comes down to the customer requirements.

Setup Cost

Cisco ACI is costly but valued for reliability, with discounts for partners, justifying the investment in uninterrupted operations.
Meraki SD-WAN offers flexible subscription terms, considered fairly priced, with discounts for longer commitments and additional related costs.
In general, Cisco ACI is on the higher side; it's not a cheap solution.
Network Technical Manager at KPMG
Cisco's pricing tends to be on the higher end compared to other vendors.
Chief Technology Officer at Mehbub General Trading PLC
Regarding pricing, setup costs, and licensing for Cisco ACI, I observe that it is on the more expensive side.
Senior Systems Engineer at a outsourcing company with 51-200 employees
If the license expires in FortiGate, the basic functionality will work, but in Meraki SD-WAN, the entire system will shut down.
Solution Architect at airtel
 

Valuable Features

Cisco ACI offers efficient traffic management, robust automation, centralized control, and enhanced security with seamless API-driven operational efficiency.
Meraki SD-WAN offers seamless cloud management, enhances security, and reduces costs with real-time analytics and centralized control.
Cisco ACI provides substantial capability; you can design your network accordingly and it's part of the SDN family, providing many benefits to the organization, especially when moving from traditional network infrastructure.
Network Technical Manager at KPMG
Instead of taking days or multiple days for a deployment of a server or application, they can do it immediately within minutes because all the configuration templates are already there in the control plane.
Consulting & Solution Integration at a comms service provider with 10,001+ employees
With the Cisco ACI fabric, you manage them as a whole, and it's an automation-driven solution, with our network development team integrating with the APIs to establish workflows for observability, fault alerts, monitoring, and more.
Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees
The architecture allows us to see whether the physical cable is connected or disconnected.
Solution Architect at airtel
The SD-WAN features of Meraki SD-WAN include the overlay setup that can connect between the switch and the Viptela device or between the VCE of another vendor without needing to be vendor-specific.
NOC Technical Lead at a tech services company with 10,001+ employees
The most valuable features I find in Meraki SD-WAN are that it's easier to manage cloud, cloud-managed, with a simpler deployment from Cisco Viptela or Cisco enterprise SD-WAN solution, and it combines the access point, so it is a much simpler deployment, usually fit for retail.

Featured Reviews

Sulaiman Olubiyi - PeerSpot reviewer
Senior Network Automation Engineer at a outsourcing company with 1,001-5,000 employees
Network automation has simplified secure multi-site connectivity and reduced daily operational effort
I believe Cisco ACI could improve by incorporating something related to agentic AI, where it can execute tasks based on particular evaluations or loop engineering, enhancing fault identification or suggestions based on each tenant's configuration. Additionally, I think they should ensure that the documentation is comprehensive. I appreciate that Cisco provides documentation, and their support engineers are helpful in case of any issues. In terms of governance and security regarding Cisco ACI's AI capabilities, I think what we call evals or evaluations is important, whereby the engineer can evaluate the functionalities of the AI in Cisco ACI, preventing it from making deletions or modifications on its own. Therefore, there should be evaluations or guardrails incorporated into the development capabilities. Regarding accuracy and reliability of output for Cisco ACI's AI capabilities, it hasn't met my expectations. What we need is something called RAG, or retrieval-augmented generation. If Cisco can implement that to utilize customer-specific data instead of general knowledge, while ensuring data privacy under GDPR laws, I think that will result in very good, reliable output.
Mageshwaran S - PeerSpot reviewer
Solution Architect at airtel
Experienced streamlined network management with enhanced usability and room for improved security features
On the security features, when compared to Fortinet, they have more patterns and AI-generated ones. Meraki SD-WAN is slowly implementing AI, but it is not yet full-fledged. If AI comes into the picture, it will be helpful. I work with Fortinet where with a single command you can deploy the entire SD-WAN along with FortiGuard within minutes. For AI, it can discover and connect, but currently, we are doing it manually. In Meraki SD-WAN, some features require additional licenses and subscriptions. If these were bundled together, such as 10 or 20 licenses, it would be very helpful for a mini branch or small campus area coverage.
