Context
Armadin announced on October 1 that it raised 255.5 million dollars in a Series B at a valuation above 2.5 billion dollars, seven months after launch. Andreessen Horowitz and Accel co-led, per Reuters.
TechCrunch ties the company to Kevin Mandia, founder of Mandiant, and describes an agent swarm approach to security.
The amount, date, valuation and AI-native security focus match Armadin's release and Reuters.
'Defense has to be automated to keep up' follows the release's framing that AI compresses the time between vulnerability discovery and exploitation.
'The attacker's speed is now the budget line' is the author's opinion.
