I am involved in a software project that requires a degree of

First define secure: do you want to protect confidentiality,
integrity, or both? RC4 (used alone and in standard ways)

Also check if the adversary has access to the running
implementation (e.g is the user, or can trojan the user's PC).
If yes, the algorithm is likely not the weak link.
