The Sentry intercepts the untrusted code’s syscalls and handles them in user-space. It reimplements around 200 Linux syscalls in Go, which is enough to run most applications. When the Sentry actually needs to interact with the host to read a file, it makes its own highly restricted set of roughly 70 host syscalls. This is not just a smaller filter on the same surface; it is a completely different surface. The failure mode changes significantly. An attacker must first find a bug in gVisor’s Go implementation of a syscall to compromise the Sentry process, and then find a way to escape from the Sentry to the host using only those limited host syscalls.
The valuation represents a 31% increase from the $6.1 billion valuation the 13-year-old company achieved in April of last year, when it raised a $575 million round led by Franklin Templeton for partly the same purpose: purchasing shares from employees, including to help them cover the taxes associated with converting expiring restricted stock units (RSUs, a form of equity compensation) into shares.

For example, as models improve at understanding semantic meaning and context, exact keyword matching will matter even less than it does now. Conversely, models might become better at assessing content quality through subtle signals like writing sophistication, logical coherence, and comprehensive coverage. This evolution favors creators focused on genuine quality over those trying to game systems through technical tricks.
