FortiSASE Pros review quotes

Deep packet inspection is easier to deploy in the FortiSASE environment. It's much simpler to configure one-touch deployment. It was considerably more convoluted to get that to work using FortiClient. All that processing horsepower is happening in Fortinet's cloud infrastructure, reducing the load on our local routers and on-prem FortiGate firewalls.

FortiSASE Cons review quotes

Peter VanDorp - PeerSpot reviewer
Feb 11, 2023
FortiSASE is a work in progress. One area where there is room for improvement is the ability to use FortiSASE on an endpoint that doesn't have the client on it. Other solutions do that by building a VPN tunnel from their on-prem router into the SASE environment. FortiSASE doesn't have that feature yet, but it is on the roadmap for Q3 of this year. I've seen it in their development environment.

They need to have more concise or precise ways to come up with the return on investment for convincing or presenting this to customers.

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.
