Cisco Secure Firewall and Zscaler Cloud Firewall are both top contenders in the security solutions market. While Cisco offers competitive advantages in pricing and integration with existing Cisco infrastructures, Zscaler is often preferred for its cloud-native approach and seamless scalability, making it more appealing for modern cloud-based environments.
Features: Cisco Secure Firewall provides advanced threat protection, VPN remote access, and seamless integration with Cisco’s network infrastructure, offering a robust security architecture for existing Cisco users. Zscaler Cloud Firewall highlights its comprehensive cloud service coverage, advanced threat intelligence, and application visibility, catering to dynamic cloud environments and ensuring reliable protection across diverse endpoints.
Room for Improvement: Cisco Secure Firewall could benefit from enhanced scalability options and simplified management interfaces to better accommodate businesses with extensive cloud operations. Additionally, integration with non-Cisco products could be improved. Zscaler Cloud Firewall might enhance its feature set by incorporating more granular firewall rules and stronger integration options with on-premise systems. Greater transparency in initial pricing and clearer ROI metrics could also be beneficial.
Ease of Deployment and Customer Service: Deploying Cisco Secure Firewall can be intricate due to hardware reliance, though it offers substantial customer support to aid existing network clients. Zscaler Cloud Firewall provides a streamlined cloud-based deployment process, minimizing setup complexity and garnering a reputation for ease in adopting across cloud-centric enterprises.
Pricing and ROI: Cisco Secure Firewall often has a lower initial cost, benefiting existing Cisco network clients with tailored configuration options, promising a solid ROI in these environments. In contrast, Zscaler Cloud Firewall may involve a higher initial investment but offers significant ROI through scalable operations and lower long-term costs by reducing infrastructure overhead, appealing to organizations prioritizing efficient scalability.
There is always a return on investment because you find you invest heavily, but your environment is secure and then you are at rest; you do not need to panic.
The biggest return on investment when using Cisco Secure Firewall is that there's no waste in any infrastructure cost and licensing costs for us.
From my point of view, the biggest return on investment when using Cisco Secure Firewall is the single pane of glass, which is a huge plus for us.
I have seen a return on investment with time saving and money saving.
I have to provide many logs, yet problems remain unresolved, often requiring workarounds rather than solutions.
I have been working with them on firewalls, wireless, switching, and routing, and the support is the best.
They have expertise and provide solutions for the most difficult problems.
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.
When something happens in the device, the failover happens very quickly without any interruption.
Cisco Secure Cloud now allows us to potentially take the management functions of Cisco Secure Firewall, move it into the cloud, and integrate it with other Cisco security products, managing everything from one single pane.
I rate the scalability as a number 10.
In this case, Twingate will be very easy compared to Zscaler.
We have often encountered split-brain scenarios during failover processes and code upgrades, which have been persistent problems for us.
We work with a cluster with high availability, so if something goes wrong, we have it functioning.
I have Cisco Secure Firewall in hospitals, hotels, airports, and shopping malls, and I have never faced complaints of a Cisco Secure Firewall crash or anything similar.
There were some stability issues due to occasional latency and lags, particularly with the GUI and report generation.
My ongoing complaint for the last six years has been the lack of CLI functionality, which hinders my ability to work on the firewall, alongside concerns regarding deployment time.
The GUI is useless for me and frustrates me to a very high degree, which led me to switch to the CLI for configuration.
Firewall as a Service can scale to a very large extent because it is a cloud-based offering that can scale up to a very large number, which is not a problem.
For now, there is no dashboard or network management system available for Twingate.
The reverse proxy feature for Data Loss Prevention (DLP) is missing.
I believe the integration of AI could improve the dashboard by making it more agile and effective in monitoring and predicting threats.
It's good to have them, however, it costs us a lot.
Basically, the license for the VPNs is for all the interfaces, and that is the thing that is really expensive compared with Palo Alto.
It's considered a premium, but people pay that price for Cisco.
Zscaler Cloud Firewall is quite expensive compared to competitors.
What stands out positively about Cisco is their training and support, which has effectively prepared engineers to work with their products.
This is very important to my organization, as we work extensively with security because we are a bank, so we can keep the data safe.
Cisco Secure Firewall allows me to safeguard Layer 7 or Layer 3 and manage the security rules with the business needs of my organization.
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.
