About Delinea:
Delinea is the identity security platform that continuously controls what AI agents, humans and machines can do and for how long. It extends privileged access management from the point of access to the moment of action, using just-in-time authorization to reduce standing privilege across on-premises, multi-cloud and short-lived infrastructure, without adding friction for legitimate users. Delinea provides visibility across every identity type, scores the risk each one carries, and preserves the context behind access decisions, making them auditable and defensible. It supports both static and ephemeral access, letting teams apply Zero Standing Privilege where risk demands it without replacing existing infrastructure.
