As well as, legacy SIEM techniques usually don’t help automated risk intelligence feeds, that are essential for staying forward of rising threats, in keeping with Younger. “Additionally they lack the flexibility to combine with security orchestration, automation, and response instruments, which assist automate responses and streamline incident administration.”
With out these trendy options, legacy SIEMs usually miss necessary warning indicators of assaults and have hassle connecting completely different risk indicators, making organizations extra uncovered to complicated, multi-stage assaults.
