MEXICO CITY–(BUSINESS WIRE)–Proofpoint, Inc., a leading cybersecurity and compliance company, today announced the appointment of Luis Isselin as its new country leader for Mexico.

We now have an exceptional opportunity to further strengthen our commitment in Mexico,” said Luis Isselin. “I look forward to bringing Proofpoint’s award-winning, innovative solutions to market, to help organizations in Mexico navigate a complex and ever-evolving cyber threat landscape to better protect their people and defend their data.”
