Legba is built by people who have lived both sides of the breach.
Hackers. Bankers.
Builders.
We have led red teams, locked down enterprises, and financed the founders building tomorrow's infrastructure. From security labs to boardrooms, we have seen how attacks start and how to stop them. Now we are securing the layer everyone overlooks: the browser.
Three people. Three lifetimes of work. One reason: the browser is where everyone's attack surface actually lives.
