Modern attacks are stealing credentials, so they're impersonating somebody on your network with privileged credentials and they're moving around. Your traditional tools that are looking for bad code, malicious software, and things like that, are not going to be effective because the attacker isn't using malicious code. They're basically impersonating somebody. So if you haven't modernized your security, then you're going to have a hard time dealing with these modern attackers.
