Code injection on Mac OS X 10.11

With System integrity protection on Mac OS X 10.11, the code injection is prevented on Apple signed processes. If the security vendor wants to reverse engineer, inject the code for legitimate purpose, what are alternatives?

- Is there possibily of security vendor can work with Apple, in a way to ceritify their apps so that only they would be allowed to do certain tasks?

Can someone from Apple respond to this query? What are the solutions to hooking into Apple processes on OS X 10.11?
