IT inflation is the rise in total technology spending even when some unit costs fall. A company may pay less per gigabyte, per CPU hour, or per SaaS seat, yet spend more overall because usage grows faster than efficiency improves. In practice, cheaper tools often lead to broader adoption, larger data volumes, more cloud activity, and higher support overhead.
In cyber security, IT inflation matters because security controls scale with the environment. More endpoints, logs, backups, cloud accounts, and AI workloads mean more data to protect, store, monitor, and investigate. Attackers can amplify this pressure by generating noisy events, forcing defenders to spend on detection, bandwidth, and analyst time. Good defense tracks cost per protected asset, alert, or incident outcome, so leaders can see whether security spending is improving resilience or just keeping pace with growth.
