Nothing kills attacks earlier than DNS-layer security.
Protection both before and during the attack
Attacks have many phases. Before launching, the attacker needs to stage internet infrastructure to support each phase. Two early phases are to redirect or link to a malicious web domain or send a malicious email attachment. For the former, most attacks leverage exploit kits (e.g. Angler) as the first stage before dropping the final payload. Cisco Umbrella effectively blocks initial exploit and phishing domains.
