The question asks about likelihood of being believed based solely on gender in a professional context. While research shows gender bias exists in various fields including tech/security, the answer cannot be determined from the information given because:

1. Belief depends on many factors beyond gender (credibility of the specific vulnerability, evidence quality, track record, etc.)
2. Organizational culture varies significantly
3. Making a definitive prediction based only on gender would itself be stereotyping

The most accurate answer is that it cannot be determined from the information provided.
