Once it is deployed, I do not have to revisit or replace the hardware.
The pricing of FortiOS is competitive and reasonable compared to other leading products such as Palo Alto and Check Point.
Fortinet is strong in terms of cost and compatibility with other vendors.
I have seen a return on investment with time saving and money saving.
I would rate them nine or ten out of ten.
Fortinet technical support is very responsive and helpful.
Support engineers sometimes lack eagerness to assist with issues such as the memory problem.
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 customers' networks grow and needs expand, we can easily switch between models to trade up devices.
It allows for the expansion of users and devices without additional licensing costs.
We have been using Fortinet for bandwidth shaping and many other bandwidth-related functions.
In this case, Twingate will be very easy compared to Zscaler.
While the product is largely stable, it sometimes faces memory issues in specific versions like 11 OE, which can be disruptive.
There were no lags, there were no issues, and no hanging of the firewall.
Stability is a seven out of ten because during version migrations, and sometimes with new versions, Fortinet is not as good.
There were some stability issues due to occasional latency and lags, particularly with the GUI and report generation.
Fortinet FortiOS faces memory issues, which can lead to unexpected downtimes.
There should be more documentation on how to use the CLI or how to perform CLI versions of tasks that can be done through the GUI.
Compared to other market leaders like Palo Alto and Check Point, FortiOS has many bugs in its initial releases.
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 is an affordable solution for us.
Fortinet products are somewhat pricey, similar to Cisco equivalents, however, they have justified their price point.
I am satisfied with the pricing, licensing, and setup costs of FortiOS, rating it nine out of ten compared to other familiar leading firewalls.
Zscaler Cloud Firewall is quite expensive compared to competitors.
It is user-friendly when it comes to turning on features, and it has been reliable and effective.
The threat intelligence in FortiOS is very high, and the system is scalable without additional licensing costs.
The solution offers good threat intelligence, which is crucial for our customers' security purposes.
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.
