Offensive cyber operations for the US
Twenty Technologies industrialises offensive cyber operations for the United States. Its founding argument is that America is under sustained attack, with adversaries infiltrating networks, stealing intellectual property and degrading the digital infrastructure everything else runs on, having learned that those attacks rarely carry consequences. The company exists to change that calculation and make an attacker think twice beforehand. Founded in 2024 and headquartered in Arlington, Virginia, its work sits under US government contract and security requirements, so roles are restricted to US persons and some require an active security clearance.
