Every option you choose closes some doors and opens others. Network-quarantine a host too early and the attacker realizes you&rsquo;re onto them and burns the foothold somewhere else you haven&rsquo;t found yet. Pull the power cable on a ransomware host and you destroy the encryption key that was sitting in memory. Watch for too long and the attacker exfiltrates the customer database.</p>
