Mendoza's disclosures led to official investigations and public attention.

She reported facing personal risk, including receiving death threats as a consequence of her whistleblowing activities. Her revelations brought attention to systemic corruption in the AFP and were cited by commentators as demonstrating her commitment to public service and ethical standards.
