Why Threat-Led Defense Should Be on Every CISO's Priority List in 2026
CISOs can no longer justify security spending without answering one question clearly:
'can I defend against the attacks that matter?'
Many CISOs are familiar with MITRE ATT&CK, yet few can say that their defenses can stop an attack. Threat-Led Defense addresses this gap by assessing defensive effectiveness against adversary procedures; the exact steps adversaries take to execute an attack. In practice, the real question isn't how many tools we have, rather which tools do I need that actually stop attacks. Many organizations suffer from tool sprawl, when two or three well-configured tools can defend against 85-90% of real-world attack activity. The focus should be on these tools, not coverage volume.
