"What set BCT Global apart was their ISO 27001 certification and genuine understanding of financial security requirements. Their on-site engineers in Tokyo became extensions of our team, while the Hanoi lab delivered code at a pace we couldn't have achieved alone. We passed every regulatory audit in three countries."
