Thank you for dealing with our wishes.

Because we are growing more and more and we have many databases in different networks.
Therefore, we are looking for a solution that will make the firewall problem more manageable for the future.
And currently I believe that managing one more service in automation would be the lesser of two evils for us.
But that's exactly why we're looking for a service that does that at all.
