When choosing a Speech-to-Text provider, it is crucial to consider the security of your data. Confidentiality, integrity, and availability are fundamental aspects of data security, known as the "security triad." Developers should ask their API providers about defense in depth, industry standard frameworks, code-level controls, technical controls supporting data security, and training for developers. Key technical controls include encryption (end-to-end, AES, TLS), malware prevention, role-based access control, handling of sensitive data, transparent data handling policies, and regular security audits and updates. Strong security practices help build trust with customers and maintain the viability of a business.
