Yes, the fact that your parents do not know may be one red flag, you'll just need more information demonstrating your relationship is genuine to compensate. It's not insurmountable but will require more effort and documentation.
In simplest form, they are looking for signs that the relationship may be a marriage of convenience, or evidence that the relationship is genuine.
For signs it is a marriage of convenience: search here for red flags.
Your task will be to demonstrate fully that the relationship is genuine: you live together, share expenses, have a longer relationship, are 'out' to friends and family on both sides (or if not, why not), children, etc.
