Early Threat Detection: Using AI as the First Line of Defense
The longer a threat remains undetected, the more costly and disruptive it becomes. This is particularly concerning given that, on average, attackers stay hidden within a network for 24 days, as highlighted in Verizon’s 2025 Data Breach Investigations Report (DBIR).
The data breaches resulting from those attacks hit the organizations quite heavily. According to IBM’s Cost of a Data Breach Report 2025, the average cost of a data breach is $4.44 million. The bright side is that this figure is 9% lower than the previous year, thanks to faster threat detection and response (TDR).
If fast threat detection and response can significantly reduce the global average cost of a data breach, imagine what early detection can do. In this post, we explore early threat detection — what it actually means, why it matters, and the role AI plays in it.
