There is an additional subscription on top of the AWS Marketplace feeds. The service appears to work as intended for the first month, and then you're sent an email explaining that you were under a trial and need to buy an Enterprise license on their site. Waste of time, false marketing.

It is frustrating because I like this service quite a lot. It is very easy to deploy and manage but there are quite a few annoyances to deal with.

First off my biggest complaint is that the Gravity Zone console won't allow you to add more than 1 AWS account integration. We manage so many different AWS accounts with hundreds of EC2 and we want 1 centralized console to manage them all, but we can't do that with this.

The console is another annoying thing, it won't let us open anything specific on a new tab. Every time we right click - open in a new tab it opens the main dashboard instead of that specific function.

Well that was a crappy experience.
Tried to download the trial on my EC2 and it gave an error but did not advise what data was a problem.
Tried again and said user already exists.
Tried via web site and could not even find the product.

They need a lot of work.

BF covered all my needs - it was easy to install it, it helped to protect AWS windows instances. Pricing model was clear and costs were acceptable.

When signing up for the free service, you have to authorize initially $250.00. A bit on the high side, but lets see. Then when you do the signup, an email comes from Amazon saying you have authorized $3,000.00. At that point it was time to cancel. Sorry guys, you need to work this out better before I come back to actually try this out.
