I am on the verge of deciding the cloud server for my chat application which will provide Text, File Transfer, Voice and Video call facility. I have seen several hosting companies who can provide the servers which can fulfill the requirement.
I am not network security expert and seeking the help and advice from expert. What kind of services should I choose from hosting company in order to protect my chat server from hackers?
For voice call I need to open 10000 UDP ports.
Kindly help me
Looking forward to hear from you
