Cisco IOS Security and Zscaler Cloud Firewall compete in the network security market. Zscaler Cloud Firewall seems to have the upper hand due to its cloud-native approach and advanced threat intelligence.
Features: Cisco IOS Security is noted for advanced routing, secure network protocols, and VPN capabilities. Zscaler Cloud Firewall is recognized for deep SSL inspection, real-time threat detection, and scalability.
Room for Improvement: Cisco IOS Security could benefit from more intuitive management tools, simplified policy configuration, and better integration with modern systems. Zscaler Cloud Firewall needs improvements in reporting capabilities, integration with legacy systems, and enhanced user training resources.
Ease of Deployment and Customer Service: Deployment of Cisco IOS Security is complex, requiring specialized skills and hardware, but it is backed by comprehensive customer support. Zscaler Cloud Firewall offers streamlined deployment thanks to its cloud-based architecture, with responsive customer service, although it may lack the depth of Cisco's support.
Pricing and ROI: Cisco IOS Security involves significant upfront costs for hardware and licensing, offering good ROI but with high initial investment. Zscaler Cloud Firewall's subscription-based pricing model is more flexible and cost-effective long-term, delivering strong ROI through reduced maintenance costs and improved operational efficiency.
The return on investment is satisfactory with Cisco products as they have long lifespans, and our customers are satisfied with them.
I have seen a return on investment with time saving and money saving.
My impression is that the support quality has deteriorated over time.
The response and support are sometimes inadequate, which detracts from the overall experience of an otherwise impressive solution.
The technical support from Zscaler was excellent.
In this case, Twingate will be very easy compared to Zscaler.
We find Cisco products stable and thoroughly tested before new software or firmware versions are released.
I find Cisco IOS Security to be a very stable product.
There were some stability issues due to occasional latency and lags, particularly with the GUI and report generation.
Cisco changes their licensing policy quite frequently, which is becoming confusing and complicated.
I believe the integration of AI could improve the dashboard by making it more agile and effective in monitoring and predicting threats.
The reverse proxy feature for Data Loss Prevention (DLP) is missing.
For now, there is no dashboard or network management system available for Twingate.
The cost of Cisco IOS Security for customers is on the higher end of pricing compared to the competition, depending on the targeted customers.
Zscaler Cloud Firewall is quite expensive compared to competitors.
There are higher-level systems such as intrusion prevention systems which detect intrusions within the system.
This solution, called Network Access Controller, handles authentication, authorization, and accounting for devices accessing the network.
It is really customized, a security policy that can be applied to the users so they can access only the resources I enable them.
Advanced threat protection features in Zscaler Cloud Firewall are practically the key component that every customer wants.
The best features that Zscaler Cloud Firewall offers are that it is AI powered and automated.
