"The most valuable feature of Cisco IOS Security is posturing."
"You can scale it when you need to."
"The technical support is good."
"Cisco IOS Security is a mature product with extensive capabilities, serving as the base for the defense layer. It offers good network visibility, which helps in rapid response through the Rapid Threat Containment feature. Its deployment and configuration are straightforward."
"The best feature is that Zscaler allows for a separation between cloud applications and URL filtering. For example, under the cloud application segment, I can bypass Microsoft Office 365 without the need to add URLs manually. It's one click, so that's handy."
"The product's most valuable feature is complete SSL inspection."
"Cloud IPS integration is seamless, and it uses a Zero Trust model. It also simplifies overall user access management."
"The initial setup is straightforward and easy in comparison with other solutions."
"The initial setup process is easy."
 

Cons

"Cisco IOS Security could improve by having more compatibility with other Cisco solutions."
"While I do not have specific recommendations for improvement, pricing can be reduced."
"The routers, don't have like long-term tendency features, or higher availability features available for the IOS. It could also use a better user interface."
"We have a very bad experience on the support. They take too much time requesting logs, and they are not coming directly online to resolve the issues."
"I wish it would be more like the next generation firewall technology. There should be more selection between the application and filtering."
"We need to pay for the license and it is expensive."
"Cisco IOS Security should improve its functionalities."
"The solution is not user friendly and it is hard to manage the GUI interface."
"There is always room for improvement."
"We encounter issues sharing IP addresses with other companies using the software."
"When it comes to scalability, the IPsec could be improved."
"They have given limited free access for a year. Instead, they should increase the file size and give limited free access for around two months. It will allow engineers to evaluate the product."
"We recently had a significant issue with Zscaler. I think they have too many customers and some of their connection edge nodes went down because there were too many requests. I think they aren't scaling enough to keep up with the demand in some areas. That's one thing they should improve."
