Cybersecurity startup Ent raised $100 million in seed funding to advance its platform that detects unusual device behavior and prevents data breaches. The company's approach represents a strategic pivot away from traditional detection methods toward proactive threat prevention. This positioning comes amid growing market interest in preemptive security solutions.

The funding round was led by Decibel Venture Capital, with additional backing from Sequoia Capital, Crosspoint Capital Partners, Craft Ventures, Shield Capital, Felicis, and In-Q-Tel. Such investor diversity signals strong confidence in Ent's prevention-focused model. The capital injection ranks among the largest seed rounds in cybersecurity this year.

Ent launched in 2025 and currently employs approximately 100 workers. CEO Lou Manousos said the funds will support platform development and team expansion through strategic hiring. The company specifically targets the market momentum behind Mythos and similar advanced vulnerability detection tools.

This massive seed investment reflects investors' belief that prevention beats remediation in cybersecurity economics. Ent's approach could reshape how enterprises allocate security budgets, potentially reducing reliance on costly incident response services that dominate current spending.
