Correct by Construction Code

OSLF – short for Operational Semantics in Logical Form – is F1R3FLY's checking tool. Before a program runs, OSLF analyses it mathematically: confirming that the data it handles is of the right kind, surfacing faults and security weaknesses, and reporting exactly what will happen when the program executes. When tested against real-world examples of notorious hacks and software failures, OSLF has consistently identified the very weaknesses that let them through. For organizations where a software failure is also a regulatory failure, OSLF turns code review from a matter of expert opinion into a matter of mathematical proof.

Conventional software is only ever tested, not proven. The F1R3FLY platform is proven, not tested.
