I also work with the proxy and some IoT devices that have been introduced in the last one or two years. Barracuda has recently released a new IoT device. Additionally, I resell and offer security applications in the cloud. Barracuda has different solutions for Microsoft Office 365, such as email filtering. Both of these solutions are ones I'm familiar with and offer to my customers.

During the evaluation process in my company, we considered Clearswift against Barracuda Email Security Gateway. My company found out that Clearswift also lacks AI functionalities, just like Fortinet, so we decided not to work with it.

We did not evaluate another solution prior to selecting Barracuda Email Security Gateway.

Over the last two years, I have looked at other solutions that might give us more ability to handle new threats. For example, I have looked at solutions that have a sandbox feature integrated into them. But, Barracuda has given us a good idea of what it proposes to do. They already have the solution that I am looking for, but because of costs, we haven't been able to deploy it.

The advantage of Barracuda is its availability. Barracuda provides really good performance and is able to handle tons of emails by the minute and by the hour. The con is that we still have critical threats coming into our environment and delivered to our users. When we compare it with other solutions, these other solutions can already detect those threats.

We have evaluated more than eight products of known vendors, and out of eight, we decided on this one.

We did not evaluate other products before going with this solution. 

We did not evaluate any other vendors. We just chose Barracuda Email Security Gateway.

My senior colleague appears to believe that Exchange is superior. Because it receives the most recent updates and Microsoft is the largest, it has more Intel on this. We are getting more data, including real-time data updates.

We did not evaluate options other than this one.

We did not look at other solutions.

We were looking for something that was easy for us to deploy and would work. We did evaluate at least one other solution before selecting this one.

In our choice of a product to use as an email security system, I mostly went by previous experience in using Trend Micro and Cisco IronPort. These are two other very good options.

This security product is part of an IT support package that we bought, and we didn't select it or purchase it for a specific reason. I don't know who the competitors are.
