Zscaler Internet Access customer service is really very good.
I find customer support to be quite adequate
They scale up really well from smaller models like the FortiGate 40 and 50 to bigger sites with the FortiGate 100 for more throughput - up to enterprise datacenters.
The variation comes in terms of the interfaces and throughputs, but from a security perspective, you get the same benefit, irrespective of whether you have an entry-level unit or an enterprise.
We determine sizing based on multiple factors: number of users, available links, traffic types, server count, services in use, and whether services will be published.
Scalability presents a challenge.
Compared to FortiGate and Palo Alto, it lags in configuration and other aspects.
Even with the highest one, the 4600, we still face issues, particularly when transitioning between screens; it becomes very slow.
With the pricing structure that they currently have, it is only for big customers.
I find Zscaler Internet Access to be highly scalable, which was one of the reasons for choosing it.

We work with a cluster with high availability, so if something goes wrong, we have it functioning.
Cisco Secure Firewall offers exceptional performance and stability.
Zscaler Internet Access is stable and capable of building resilient architectures.
Zscaler Internet Access is very stable, and I would rate its stability as nine out of ten.
When considering Sophos XG, which we also use, the logging and reporting functionality is notably more efficient.
These sessions should be around five to ten minutes long, allowing users and partners to quickly grasp the information without disrupting their daily tasks.
The solution should be able to implement machine learning and analytics of all the logs for threat detection and protection.
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.
Firepower Management Center is quite out of date compared to other vendors.
The integration between Cisco products themselves presents difficulties, such as SD-WAN configuration.
The response time and engagement model for technical support could be improved to handle complex outages more efficiently.
In future updates, I would like to see some of the features bundled into the existing product set, perhaps more AI features and a refreshed interface.
Zscaler Internet Access has introduced AI control for tools such as ChatGPT, providing options to restrict to text-only input without file or image uploads through CASB restriction controls.
Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us.
It offers cost savings as it is generally cheaper than the competition.
It is about 20% cheaper.
It's good to have them, however, it costs us a lot.
It's considered a premium, but people pay that price for Cisco.
There are a lot of in-place contracts for us that provide the benefit of discounts.
Zscaler Internet Access is recognized as an expensive solution.
Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability.
Of course, it is an expensive product.
These features help reduce our downtime, manage the ISPs, and deploy SLAs for all the website traffic.
The most valuable feature of FortiGate is FortiView which provides proactive monitoring.
We got a firewall and gave an SSL VPN to my client to connect to their servers, after which, such kind of activities involving ransomware attacks stopped.
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 prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses.
The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights.

Reviews from Real Users
Below are some reviews and helpful feedback written by Zscaler Internet Access users.
A Service Manager at a construction company says, "There are a bunch of different capabilities that are valuable within the platform. We use quite a lot of them, but not everything. The ones that are most important to us are the URL Filtering and the application control. For our needs, the cloud-native proxy architecture is a very good solution. This architecture helps with cyber threats because we inspect most of the traffic and we can see that a lot of threats are stopped directly in the secure web gateway."
Owen N., Security Architect at Claro Enterprise Solutions, explains that the solution’s most valuable features include “The integration of the gateway that inspects all ports and protocols. So, there is threat prevention; The cloud sandbox; VNS security; Access control that will protect URL filtering and the cloud firewall; Data protection that will protect your gateway, like your CASB or your cloud DLP; The capabilities of this will point your traffic to Zscaler Cloud.”
An Architecture Senior Manager at an insurance company mentions, "The data loss prevention feature is the most valuable. It stops our users from inadvertently leaking our customers' data to the Internet or anywhere else it shouldn't go." He also adds, “The solution provides quick access to cloud services, securing our data and allowing us to inspect all our traffic.”
