Hi dear friends, How can i protect my network from ransomware attacks? who has advanced information about --how this virus find us?what is their mechanism? how crack our passwords and usernames?
You should start by reviewing the Cisco collateral material found here:
After reading through that, you can post more focused questions if you have any.
I've never heard of the Arconis product before.
This is a Cisco forum and we mostly focus on Cisco products here, primarily in the networking side of things as opposed to host/server-based tools. (Cisco AMP for Endpoints being an exception to that.)
in case that you want protect your endpoints against ransomware Cisco can offer you AMP + Umbrella.
These could help you to avoid new attack at your endpoints but for sure it's not enough. You need to consider many aspects: firewall, mail control, endpoints..
