Apple has SecureTransport[1] and it is open source[2], it had the goto fail bug from earlier this year. Shoving money at the problem isn't necessarily the answer. The problem is the TLS spec is a confusing, arcane spec riddled with tons of gratuitous addons and extensions. Implementing all or even most of it without error/bus is simply a very hard problem
