Zscaler Internet Access support is strong and responsive, though some users seek quicker resolutions and better online resources.
If there is a solution in the market, the people supporting it should be technical enough to resolve issues at their first level or second level, or at least at the third level.
The technical support from Fortinet is highly commendable
They improved their technical support assistance recently.
The technical support for Zscaler Internet Access is rated around seven out of ten due to some response time issues and the engagement model.
I find customer support to be quite adequate

Room For Improvement

FortiSASE needs enhancements in security, integration, and user-friendliness, facing challenges in deployment, pricing, and technical issues.
Zscaler Internet Access needs better integration, user-friendly features, improved support, and competitive pricing to enhance user experience.
FortiSASE implementation is too complex where other products take two to three months or maximum four months to implement, FortiSASE took more than double that time.
While connectivity from outside to inside is okay, inside to outside is not.
I believe the SASE solution from Fortinet requires improvement by developing a cloud management platform that handles tasks like setting up SD-WAN and automating firmware updates.
The response time and engagement model for technical support could be improved to handle complex outages more efficiently.
One feature I am missing is the ability to connect automatically to internal monitoring systems.

Zscaler Internet Access is recognized as an expensive solution.
 

Valuable Features

FortiSASE offers centralized management, strong security, and cost savings with user-friendly features, making it globally appealing.
Zscaler Internet Access delivers comprehensive cloud-native security with threat protection, ease of use, and centralized management for remote users.

The important aspects are twofold. One is authorization, and the second is access control.
It also provides enhanced inspection capabilities, including SSL decryption, while maintaining compliance with organizational security policies.
The SSL inspection also offers added security, facilitating the exchange of critical data.

Featured Reviews

Yusuke Murasato - PeerSpot reviewer
Efficient access control and authorization with easy configurations
The important aspects are twofold. One is authorization, and the second is access control. FortiSASE can operate in a cloud environment with client certificates for authorizations and access control using features like PostureCheck. The service assesses device security, checking updates on antivirus software and confirming Windows OS specifications. I can use it anywhere I want as long as I have an Internet connection. It's very easy to configure the environment.
AshwaniTyagi - PeerSpot reviewer
Offers good reliability and availability to users
Sometimes, cost is one component that customers complain about, especially if they compare it with some of its competitors. Zscaler's pricing seems to be a bit on the higher side. I think the pricing model is also something that the tool can probably look into to optimize or improve for the customer so that it can be a competitive tool commercially. The solution's technical support needs to be improved, especially by offering a better support structure for different geographical areas.
