We did not evaluate other options. 

We have previously looked into Sophos UTM and Palo Alto.

I downloaded reports for CrowdStrike Falcon and FortiEDR from peerspot.com to see how they are in terms of performance.

It's all part of our Fortinet ecosystem, so we didn't really consider alternatives. I have a significant investment in FortiGate firewalls, so it just made sense to add FortiAnalyzer.

Yes we did evaluate paloa alto , but it went into backburner due cost factor.

An alternative solution is SolarWinds, which analyzes server performance, and could be a competitor's CM solution or a managed service that sends data from sensors on the site to their facility. The primary distinguishing feature of SolarWinds is its form factor. SolarWinds must be installed on a server and requires server resources. In the past, a large amount of OS and other resources were necessary, but the form factor has remained the same.

There is a lot of competition for Fortinet in this area, including USM and Palo Alto.

We did not evaluate other solutions before choosing this product.

A company implemented a POC for us, and after that, we found that this could be a good product for our purposes.

We did not look at any other options, because Fortinet was elected for use by the end user.

We tried NetFlow Analyzer, and the product was good but it was highly expensive.

This product is only dedicated to packet analyzing, automation, and things like that. I have not used analyzers of other vendors. However, other solutions do provide similar functionalities. 

I've personally looked into other security solutions, just to understand the market for myself. I've personally compared Fortinet, Meraki, Check Point, and Cisco ASA Firewall in terms of their safety and security capabilities. 

We evaluated SonicWall and Cisco.
