Dream Security, an IT-Harvest Cyber 150 company, was founded in January 2023 and has raised more than $150 million in capital. The company, which is commonly known as Dream, was particularly attractive to investors in 2025.

First Dream announced a $100 million Series B (February 2025) led by Bain Capital Ventures at a $1.1 billion valuation. Group 11, Tru Arrow, Tau Capital and Aleph were among the participants.

In September 2025, Dream announced $45 million in secondary financing led by 7GC, along with Tru Arrow Partners, TAU Capital, and Group 11.

Dream provides complete organizational asset mapping through automated analysis of data flows and dependencies, eliminating reliance on manual audits while revealing unauthorized access points and misconfigured systems. They go beyond just asset and vulnerability management to simulate attacker behaviors through AI agents representing a hacker replication model to anticipate tactics and enable preemptive countermeasures against both known and novel threats.
