SIEM Is Changing. What Should It Still Own?
Security operations center (SOC) teams are being asked to reconstruct incidents across cloud accounts, identity systems, and leftover on-premises gear, often inside the same audit window. The raw material for that work is scattered. A firewall, an identity provider, and an endpoint agent each fire in their own console, and the people who have to explain what happened still need one timeline. That squeeze is showing up in spending. IMARC Group put the global security information and event management (SIEM) market at USD $7.0 Billion in 2025, pointing to cyber threats, regulatory mandates, and cloud adoption as the main drivers.
