What is Dwell Time in Cybersecurity?
The number of days an attacker remains undetected inside a compromised network, measured from initial access to discovery. Global median dwell time has decreased in recent years but still averages weeks to months in many organizations. Lower dwell time indicates better detection capabilities and reduces the damage attackers can inflict during their time inside the network.
Why Dwell Time Matters for Your Cybersecurity Career
Dwell time is a headline metric in breach reports and a key indicator of security program maturity. CISOs track dwell time to measure detection improvement over time. SOC analysts and threat hunters directly reduce dwell time through proactive investigation. Security engineers who improve detection coverage measurably contribute to lowering this critical metric.
