An ethical hacker kept finding the same weakness outside the fortress. He turned that recurring clue into Black Kite - and a career spent making invisible supplier risk legible.
HackerOne Made a Business Out of Inviting Strangers to Break In
The bet sounded reckless: give hackers permission, set a bounty, and listen. One Pentagon pilot and hundreds of thousands of validated vulnerabilities later, HackerOne is trying to turn that human network into a continuous, AI-assisted security system.
Synack Put 1,500 Hackers Behind One Locked Door - Now AI Is Knocking
Annual pentests were too slow, scanners were too noisy, and inviting strangers to attack corporate systems sounded absurd. Synack turned that trust problem into a platform - then added an autonomous red agent without removing the humans who prove what matters.
