Yes. Its just files so you are pretty flexible to do what you want.

I've heard of use cases where suricata-update is used on one machine,
and the resulting /var/lib/suricata/rules/suricata.rules is then pushed
out to sensors with tools like Ansible, Salt, etc. Of course you could
just use scp, or whatever. Just remember to SIGUSR2, or use suricatasc
reload-rules to reload your rules after placing the new file in place.
