Networks Lead Engineer at a mining and metals company with 1,001-5,000 employees
Reliable performance with good network control and great integration capabilities
Pros and Cons
- "There is good integration with third-party systems like antivirus patch management, MDM."
- "The pricing and licensing structure are not ideal for customers."
What is our primary use case?
We primarily use the solution in our infrastructure.
What is most valuable?
I'm very satisfied with the product. It has been excellent so far.
From the performance perspective, it is excellent. The outcome is as expected, giving control to the network.
There is good integration with third-party systems like antivirus patch management, MDM.
What needs improvement?
They need to simplify the processes and management more, as well as the platform. Their user experience is a bit complicated, and it's not easy to manage. They need to do something to enhance the management console and make it more simple and easier to use.
I need to see stronger integration with Cisco SDN. Instead of treating it as a separate appliance, it should be a built-in feature in the SDN solution. This is one of the things that will reduce the complexity of Cisco's architecture. Instead of having multiple appliances, and getting lost in-between, and not knowing where is the problem is, everything can just be in one place. It will be better to move this feature or this technology as a built-in technology in the SDN solutions, similar to DNA and ACI.
The pricing and licensing structure are not ideal for customers.
For how long have I used the solution?
I've used this solution for about five years, both in my previous company and my current company as well.
What do I think about the stability of the solution?
The solution provides excellent stability and reliability. There are no bugs or glitches. It doesn't crash or freeze.
What's my experience with pricing, setup cost, and licensing?
We are a customer and an end-user.
Cisco, on the price, is not good now. This might entice customers or end-users to go for another cheaper solution where they can still find most of the features Cisco offers.
They are now offering subscription licenses, and you have to pay thousands of dollars every year for maintenance and renewing support. Most users will not accept this new strategy of Cisco. It's not like HP or Dell, where, when you purchase the hardware and it's a lifetime license. It's a lifetime subscription. You don't need to renew the license every two years. Therefore, from a price perspective, no, Cisco's not good. Their strategy now seems to be pushing customers to go for other solutions.
What other advice do I have?
The product is excellent and I would rate it at a nine out of ten.

The community support is satisfactory, it is very easy to get support. You can find any documentation and support within the community.
