Hi,
If the servers are all on Inside interface and they only need to access the Internet (servers initiate the traffic) then your config is fine.
By default, with no ACL assign, the ASA will allow the traffic from higher security interfaces (Inside) to lower security interfaces (Outside).
No NAT statement is required since "nat-control" command is not applied so all is good.
Please rate if this helped.
Regards,
Daniel
