Incorporating a Prevention Mindset into Threat Detection and ResponseThreat detection and response systems, by definition, are reactive because they have to wait for damage to be done before finding the attack. With a prevention-mindset, security teams can proactively anticipate the attacker's next move, rather than reacting to specific threats or trying to detect the latest techniques in real-time.
The report covers areas enterprises should focus on:
What positive response looks like.
Improving security hygiene.
Combining preventive actions with red team efforts.
Incident Readiness and Building Response Playbook
In this special report, learn the Xs and Os of any good security incident readiness and response playbook.

As mentioned in the post, the NGFW should take care of the deep packet inspection for only the traffic you potentially want inside your network. That firewall should see very little traffic except for the known IPs, ports and protocols which are candidates to be allowed all the way in.
And an outbound ACL (a.k.a. egress filtering) is a very powerful weapon against data exfiltration and many types of malware. You may still have a Trojan but if it can't phone home......
